OVERVIEWPower, heart rate, or RPE (rate of perceived exertion or how you feel)? Which data point is best for gauging intensity during training or a race, and which is best for monitoring training progress? Coach Adam Pulford tackles these frequently asked questions in Episode 249 of "The Time-Crunched Cyclist Podcast". Although ALL THREE metrics have their place, Coach Adam reveals the hierarchy for what matters most and what metrics are used for context. TOPICS COVEREDPower vs Heart Rate vs RPE HierarchyHow to keep HR from drifting up during intervalsWhy HR might drop during intervalsWhy prioritize Power first, then RPE, and HR lastTraining at the top vs bottom of power zonesAll about Rate of Perceived Effort (RPE)Why three data points are better than oneASK A QUESTION FOR A FUTURE PODCASTLINKS/RESOURCESEston, R., & Connolly, D.

Send us a textIn this illuminating solo episode, I dive deep into the interconnected realms of applied physiology and neuroscience to explore how honoring our evolutionary design can transform the way we live, perform, and thrive. With a focus on bridging the gap between the world within us and the rapidly evolving modern world around us, I break down the fundamental principles of how our bodies and brains are designed to function under "normal conditions"—a concept that feels increasingly distant in today's fast-paced, convenience-driven lifestyle.From the role of intermittent fasting in tapping into evolutionarily conserved mechanisms to the power of hormetic stressors like exercise, cold exposure, and mindful breathing, this episode unpacks how intentional, evidence-based lifestyle choices can support neuroplasticity, resilience, and overall well-being. I emphasize the importance of understanding key biomarkers like heart rate variability (HRV) to track and optimize our nervous system's adaptability and share actionable insights to help you integrate progressive, sustainable practices that elevate both mental clarity and physical performance.Whether you're navigating a health plateau, looking to build healthier habits, or simply aiming to deepen your connection with your body and mind, this episode offers a practical roadmap to reclaiming control over your physiology and psychology. Join me as I reflect on my own journey from dependency on external solutions to achieving self-mastery through a deeper understanding of how our bodies are designed to thrive in an ever-changing world.Looking to discover your science and optimize your life?APPLY FOR HEALTH OPTIMIZATION COACHINGhttps://coaching.knowyourphysio.org/Key Points From This Episode:Gap between modernity and physiology [00:01:06] Intermittent fasting and longevity [00:04:50] Heart rate variability and stress [00:09:21] Neuroplasticity and mental health [00:14:12]  Visit KYP Blog:https://knowyourphysio.org/learnSupport the show

Les bains glacés, souvent promus par des sportifs, influenceurs ou adeptes du bien-être, sont vantés pour leurs prétendus bienfaits : récupération musculaire, amélioration de la circulation sanguine, gestion du stress et renforcement du système immunitaire. Mais qu'en dit la science ?Récupération musculaireL'un des usages les plus populaires des bains glacés concerne la récupération musculaire après l'effort. Une méta-analyse publiée dans Sports Medicine (2016) a confirmé que l'immersion dans de l'eau froide (10-15 °C) réduit efficacement l'inflammation et les douleurs musculaires à court terme, en ralentissant la circulation sanguine et en diminuant l'œdème des tissus. Cependant, une étude dans le Journal of Physiology (2015) a souligné que cette pratique pourrait ralentir les adaptations musculaires et la croissance à long terme, car elle inhibe les processus inflammatoires nécessaires à la régénération naturelle des muscles.Circulation sanguine et inflammationLes bains glacés provoquent une vasoconstriction (rétrécissement des vaisseaux sanguins), suivie d'une vasodilatation lorsqu'on sort de l'eau. Ces effets, étudiés dans European Journal of Applied Physiology (2007), peuvent temporairement améliorer la circulation sanguine périphérique. Cependant, les preuves sur des bénéfices durables pour la circulation ou la gestion systémique de l'inflammation restent limitées et controversées.Gestion du stress et bien-être mentalL'immersion dans l'eau froide stimule la libération d'hormones comme l'adrénaline et les endorphines. Une étude dans PLoS One (2014) a montré une amélioration immédiate de l'humeur grâce à l'augmentation de ces neurotransmetteurs. De plus, une recherche publiée dans Medical Hypotheses (2008) suggère que les bains glacés pourraient réduire les symptômes de dépression légère à modérée, bien que des études supplémentaires soient nécessaires pour en valider l'efficacité à long terme.Renforcement du système immunitaireL'idée que les bains glacés renforcent l'immunité a été popularisée par des figures comme Wim Hof. Une étude publiée dans PNAS (2014) a examiné l'impact de cette pratique combinée à des techniques de respiration sur l'activité immunitaire. Les participants ont montré une meilleure réponse immunitaire après une exposition contrôlée à une toxine bactérienne, mais ces résultats restent spécifiques à ce protocole et ne prouvent pas d'effets généralisables.ConclusionLes bains glacés présentent des bénéfices scientifiquement validés, notamment pour la récupération et le bien-être immédiat. Cependant, leurs effets à long terme sur la santé restent incertains. Avant d'intégrer cette pratique à votre routine, considérez vos objectifs personnels et consultez un professionnel, surtout si vous souffrez de problèmes cardiovasculaires. Hébergé par Acast.

La survie lorsqu'une personne est enterrée vivante dépend de plusieurs facteurs cruciaux : la quantité d'oxygène disponible, l'espace dans lequel elle est enfermée, le niveau de stress, ainsi que l'état physique de la personne. Les études scientifiques sur ce sujet sont limitées pour des raisons éthiques, mais certains principes de physiologie humaine permettent d'estimer le temps de survie. Facteurs Affectant la Survie 1. Quantité d'Oxygène Disponible : Le facteur le plus déterminant est la quantité d'air disponible. Un adulte moyen consomme environ 0,5 litre d'oxygène par minute au repos. Un espace confiné tel qu'un cercueil ou une cavité d'environ 0,5 m³ contiendrait environ 150 litres d'air. Étant donné qu'environ 21 % de l'air est composé d'oxygène, cela représente 31,5 litres d'oxygène disponible. À un rythme de respiration normal (repos), la personne consommerait cette quantité en environ 2 à 3 heures. Cependant, l'augmentation du dioxyde de carbone (CO2) dans un espace confiné entraînerait une suffocation rapide. 2. Augmentation du CO2 et Asphyxie : À mesure que la personne consomme de l'oxygène, la concentration en CO2 augmente, créant une situation d'hypercapnie. Une étude sur les effets de l'hypercapnie montre que la concentration de CO2 entre 5 et 10 % provoque des symptômes graves comme l'hyperventilation, la panique et, finalement, la perte de conscience . En espace clos, cela peut survenir en moins d'une heure après l'épuisement partiel de l'oxygène disponible. 3. Impact Psychologique et Physique : Le niveau de panique influence également le taux de consommation d'oxygène. Une personne calme pourrait ralentir sa respiration, prolongeant ainsi sa survie. Mais en réalité, la plupart des gens éprouveraient de la panique, ce qui augmente la consommation d'oxygène. Un article publié dans *Resuscitation* montre que l'hyperventilation due à la panique peut doubler ou tripler la consommation d'oxygène . Études et Expérimentations Les études empiriques directes sur la survie en étant enterré vivant sont rares, mais il existe des récits historiques et des reconstitutions contrôlées. En 2011, un illusionniste américain, Anthony Britton, a tenté de survivre à un enterrement volontaire en étant enfermé sous terre. Cependant, il a dû être sauvé après moins de 30 minutes, soulignant les dangers liés au manque d'oxygène et à la panique . Une autre étude sur la survie en espace confiné, publiée dans *Applied Physiology*, révèle que l'hypoxie (manque d'oxygène) associée à l'accumulation de CO2 peut entraîner une perte de conscience en moins de 15 à 20 minutes, suivie de la mort dans l'heure si aucune ventilation n'est disponible . Conclusion En résumé, une personne enterrée vivante pourrait survivre quelques heures au maximum, mais en réalité, les niveaux de panique et la disponibilité limitée d'oxygène réduiraient ce temps de manière significative. La mort survient généralement par asphyxie, provoquée par l'épuisement de l'oxygène et l'accumulation de dioxyde de carbone. Bien que des récits et des expériences existent, les cas réels de survie en étant enterré vivant sont extrêmement rares, et la science ne soutient pas l'idée d'une survie prolongée sans ventilation adéquate.

Episode 2672: Christian Finn of MuscleEvo.net debunks the common claim that squats and other compound exercises significantly increase testosterone levels and accelerate muscle growth. Despite temporary hormonal spikes post-exercise, the research indicates these effects are too fleeting to impact muscle hypertrophy or strength gains meaningfully. Finn recommends focusing on overall lifestyle changes for lasting hormonal balance. Read along with the original article(s) here: https://muscleevo.net/squats-testosterone/ Quotes to ponder: "Heavy resistance training involving large muscle groups does have the potential to increase post-training testosterone levels." "Any temporary surge in post-training hormone levels is too small to have any impact on muscle protein synthesis, muscle fiber hypertrophy or strength gains."

The ancient Mayan and Incan civilisations were the first to record various theories of consciousness. Since then many different definitions have sprouted up in various spiritual, psychological, medical, and moral texts in both Eastern and Western cultures. The ancient Mayans were among the first to suggest an organised sense of each level of consciousness, it's purpose and relationship to humanity. Then about 150 years ago, Sigmund Freud, speaking to consciousness and what in the dickens it might be - suggested that psychological processes are flows of psychological energy in a complex brain. Complex is right! So then this would mean that our behaviour, our habits and actions are all essentially influenced and controlled by psychological energy, that is, our beliefs and patterns. On top of that, specific patterns, real or imagined, will be reinforced by emotional experiences, conditioning, and even psychedelic drugs. Throughout human evolution the ability to process patterns became increasingly sophisticated as the parts of our brains involved in the processing of images - the cerebral cortex, particularly the prefrontal cortex - started to expand. Recognising our patterns allows us to predict and expect what is coming. The process of pattern recognition involves matching the information received, with the information already stored in the brain. I first embarked formally on this road to self-discovery a few decades ago in my early 20's, to start the long process to unpack my stuff. (No, we didn't have EMDR back then.) Kinesiology was the modality where the yellow brick road took me first. When I first met Kim O'Brien for kinesiology - to start looking at some of my negative patterning, the things that were getting me unstuck, well, really ruining and ruling my life, Kim was using the Enneagram and other systems to unpack this stuff, and today we're going to hear where she has gone in this field of Patterning since then. Kim O'Brien started as a kinesiologist, then studied Applied Physiology which are both disciplines that look for, and aim to correct patterns in the body. Over several years of intense work in this area it became obvious to her that patterns manifest everywhere and the most challenging ones - which can prevent healing at all levels - are the ones buried in the subconscious.  Welcome to the podcast Kim. Its a pleasure to have yo here as my guest. I'd like to start by asking - are you still using the Enneagram as a tool, and are there any new methods or systems that you're now using in clinic, and in your own life.

Anabolic resistance, a phenomenon marked by reduced muscle protein synthesis and impaired muscle maintenance, is a significant concern in aging populations. In this episode, Dr. Armstrong and Corbin Bruton discuss anabolic resistance and its impact on healthy aging.They explore the factors contributing to anabolic resistance, ranging from age-related declines in muscle protein synthesis to alterations in cellular signaling pathways. Despite its prevalence, the hosts challenge the notion that anabolic resistance is an inevitable consequence of aging, emphasizing the role of lifestyle interventions in mitigating its effects. Through discussions on resistance training, protein intake optimization, and other strategies, they highlight actionable steps individuals can take to combat anabolic resistance, maintain muscle health, and… age well.Articles:Aragon, A.

As an adult, there's a good chance you've experienced moments when your brain feels foggy or you struggle to concentrate. This phenomenon, commonly known as "fuzzy brain" or "brain fog," can be frustrating and impact your daily life. But what causes these symptoms, and are there solutions to combat them? In this article, we will delve into the causes of fuzzy brain symptoms and explore solutions to enhance your clarity and cognitive function. So, if you have ever wondered why your brain always feels foggy, keep reading to gain a better understanding of this condition and how to address it. What is Fuzzy Brain or Brain Fog? "Fuzzy brain," commonly referred to as "brain fog," is not a medical condition in itself but a term used to describe a set of symptoms affecting cognitive abilities. People experiencing brain fog may feel confused, disorganized, and have difficulty focusing, putting thoughts into words, or remembering things. This cognitive dysfunction is characterized by memory problems, lack of mental clarity, poor concentration, and an inability to focus, often described as mental fatigue. Common Signs and Symptoms Brain fog, often described as "fuzzy brain," is characterized by a constellation of symptoms related to cognitive dysfunction, including confusion, memory problems, lack of mental clarity, poor concentration, and the inability to focus. While the term "brain fog" is not always used explicitly in scientific literature, the symptoms it encompasses are well-documented in studies related to cognitive function and mental health. Below are the most common symptoms: Cognitive Impairment and Memory Problems: Cognitive dysfunction, including memory lapses and difficulties with recall, is a hallmark of brain fog. A study by Banks, S. et al. (2020) on sleep deprivation highlights how lack of sleep—a common contributor to brain fog—can impair memory and cognitive performance, simulating the symptoms of brain fog.Banks, S., Van Dongen, H. P. A., Maislin, G., & Dinges, D. F. (2010). Neurobehavioral dynamics following chronic sleep restriction: Dose-response effects of one night for recovery. Sleep, 33(8), 1013–1026. Lack of Mental Clarity and Poor Concentration: People experiencing brain fog often report a lack of mental clarity and difficulty concentrating.Gavelin, H. M., Neumann, S., Kovacs, A. H., Malmberg, F., Malmberg, J., Bonde, A. H., ... & Wicksell, R. K. (2021). Cognitive impairments in individuals with long COVID: A 6-month follow-up study. EClinicalMedicine, 41, 101159. Feeling of Mental Fatigue: Mental fatigue is another symptom frequently associated with brain fog. This encompasses a subjective sense of tiredness and a lack of energy for mental tasks.Marcora, S. M., Staiano, W., & Manning, V. (2009). Mental fatigue impairs physical performance in humans. Journal of Applied Physiology, 106(3), 857–864. Difficulty Stringing Thoughts Together: People with brain fog often describe a sensation of struggling to string thoughts together, leading to difficulties with speech or articulating ideas. This symptom points towards an impairment in executive function, which is crucial for planning, decision-making, and verbal fluency.Diamond, A. (2013). Executive functions. Annual Review of Psychology, 64, 135–168. Disrupted Executive Function: Executive dysfunction, including difficulty planning, organizing, and multitasking, is often reported in the context of brain fog. Such symptoms can stem from various conditions, including chronic stress and poor sleep. Stress can alter executive functions, leading to decreased cognitive flexibility and increased rigidity in thoughts and actions.Arnsten, A. F. T. (2009). Stress signalling pathways that impair prefrontal cortex structure and function. Nature Reviews Neuroscience, 10(6), 410–422. These symptoms collectively contribute to the subjective experience of brain fog, making daily cognitive tasks more challenging and impacting ove...

Richard Morgan is 93 years old but a late love of indoor rowing has helped him develop into a physical specimen for his age. He spent most of his life spurning fitness and only took up indoor rowing - of which he subsequently became a world champion in his field - in his seventies. Richard is the subject of a recent paper in the Journal of Applied Physiology which looked at his training and diet regimes and has found he has the heart, muscles and lungs of someone less than half his age. His grandson Lorcan Daly is a sports and exercise lecturer at the Technological University of the Shannon in Ireland and he's one of the researchers behind the paper.

In this episode of the Owens Recovery Science podcast we chat with Laura Opstedal, PT of Build Physio in Bozeman, MT. Laura has extensive experience rehabbing Achilles repairs over the course of her career which provides her a first-hand perspective on the evolution of surgical techniques as well as integrating forms of measurement like force plates and novel treatment strategies like early weight bearing and BFR. Within we talk all things Achilles which apparently we're now calling the Taylor Swift of tendons.

Have you ever TAKEN THE PLUNGE?? Cold water immersion is one of hottest trends in the health and wellness world.  A number of theories exist re: the benefits of cold water immersion. Generally we think of recovery from exercise, muscle soreness, injuries, etc. But the recent “craze” has been due to the potential to improve depression and anxiety, boost immunity, and perhaps even extend our longevity. But does it work? Is there data to support it?? LET'S ASK AN EXPERT! Our expert today is Mike Tipton, PhD, FTPS! Dr. Tipton is a Professor of Human & Applied Physiology, Extreme Environments Laboratory, School of Sport Health & Exercise Science, University of Portsmouth, UK. He has published over 750 scientific papers, reports, chapters, abstracts and books in his research areas of drowning, thermoregulation, environmental and occupational physiology, and survival in the sea.  He has been a consultant in survival and thermal medicine to the Royal Air Force, UKSport and the English Institute of Sport (EIS).  Prof Tipton is a Fellow of the Royal Society of Medicine and The Physiological Society.  He was awarded his MBE for services to physiological research in extreme environments; the Ireland Medal for saving lives from drowning worldwide; and the H&L Swiftwater rescue lifetime achievement award from the USA. LET'S DIVE IN, SHALL WE?? Key highlights in this episode include: What's the basic physiology behind cold water immersion? What happens to our bodies when we make ourselves cold? Does it differ in full submersion vs a shower? Does it change if we put our faces in the cold water as opposed to just our bodies? What temperature is most appropriate for a cold plunge? How long should we stay submerged? What are the potential short and long term benefits? What does the research suggest? What are the risks/potential downsides? Who should NOT be doing this? What about cryochambers? Do they work? Who is Wim Hof? Should we do as the Iceman does?? Dr. Tipton recommends the following resources to learn about cold water immersion: The University of Portsmouth webpage- including Dr. Tipton's profile. 2022 British Medical Journal article "Cold Water Therapies: Minimising Risks". Beth Francis' video "100 Days of Vitamin Sea", chronicling her journey treating her intractable migraines with open water swimming. Check out Prof Tipton on Twitter, @ProfMikeTipton!

This episode is Brought to you by Four Sigmatic. Give yourself permission this year, proactively spend more time with the people that you care about, and again, this could be a date night, this could be, family get togethers, this could be, getting together with a friend to exercise or go for a walk, this could be scheduling lunch or dinners together, this could be making time for a cup of coffee, whatever the case might be. Whatever the case might be. And a little funny story, and I've never shared this before, I've never gotten a cup of coffee with someone, like out there in the streets, there are all these cool coffee shops. I've never done it. I've never done it. Alright, I just haven't. I didn't even drink coffee most of my adulthood, and this was until a few years ago when my wife, I was utilizing these dual extracted medicinal mushrooms from Four Sigmatic in making teas, but they were sending coffee as well, and my wife was just like... It was... She loved it. It was just her highlight of her morning, and I was just like, what is it? Because the last time I had tasted coffee, I was a kid, and I was with my grandmother and I'm wondering, why is this lady always drinking this? Whatever this is, and I drank it, I took a sip and I was like, I literally... The thought that crossed my mind when I sipped that coffee when I was probably seven years old, is that something is wrong with my grandmother. There's something wrong with her. How in the world can she drink this stuff? And that was that, and I even actually bought her for Christmas a little container of her favorite coffee, which was Folgers, is what she was using. The best part of waking up. And she actually, and this was... Again, I was like seven or eight, and when I was maybe in my late 20s, I went to my grandmother's house. And that Folgers gift that I had bought her that had a bow on top was in her cabinet still, she had kept it all those years. And so there was this beautiful affinity with this, but I was just like, I'm never drinking this stuff again. And so once I tried the coffee and had it the way that I was preparing it for my wife, like blending some high quality fats into it and things like that. It was like, oh, I get it. This is pretty awesome. But for me, I haven't gone and gotten coffee with anyone, I have gotten some tea, I have had some tea, like back in the day if somebody would wanna get coffee, I'd get some tea. But now it's because I'm kind of spoiled. I have the most incredible coffee in the world that I get from these people that I truly trust, because the coffee industry is crazy right now. All these different microplastics and toxic molds and pesticides and all the stuff that people are just consuming every single day. And many of these chemicals are in a category known as obesogens, these are obesity-causing agents that alter our metabolic health and also carcinogens, these are cancer-causing agents, and so Four Sigmatic is all organic, the most incredible coffee, all organic, but also it's blended with dual extracted medicinal mushrooms like lion's mane, and scientists at the University of Malaya discovered that compounds in lion's mane are able to significantly improve the activity of nerve growth factor in the brain. Nerve growth factor is essential in the regulation of growth, maintenance, proliferation and the survival of various brain cells, it's pretty powerful stuff to say the least, and also there's several studies indicating its role in helping to reduce issues related to mental health, things like anxiety and excessive stress, the lion's mane is really remarkable. And that's what I actually had today, the Four Sigmatic ground coffee lion's mane blend with Chaga as well, and Chaga is a powerful, powerful antioxidant and mountains of studies affirming its benefits with the immune system. So this is what I make for myself and my wife every morning, and I highly encourage you to check them out, go to foursigmatic.com/model. That's foursigmatic.com/model, and you're going to get 10% off all of their incredible coffee blends, if you're not into coffee like I used to be, they also have incredible elixirs or tea they're in a tea version basically, with these incredible science-backed long storied medicinal mushrooms as well, and they also have a great hot cocoa, a reishi hot cocoa that my son loves, my youngest son, Braden really loves, that reishi hot cocoa. So many great things, you get 10% off store wide, also you get access to some free shipping opportunities and stuff like that, so they're amazing. Really, really amazing. Been a big part of my family's lives for many years foursigmatic.com/model This episode is brought to you by Organifi. I'm imploring us to make it a mandate this year. This is the year to have some more home-cooked meals focus on a system for some food prep, making some delicious meals, spending a little bit of time in the kitchen, or having your family find a strategy for that so that you can have healthier ingredients and also ingredients that are not riddled with these toxic oils. And I'm a big fan of helping to create a fun kitchen culture and family culture around food and around the dinner table. And that was really the inspiration behind my latest book, The Eat Smarter Family Cookbook, which I am incredibly honored to say is a USA Today national bestseller. And it was a number one cookbook in the United States, number one new release cookbook in the United States when it came out. That is crazy pants, all right? But a book like that could not do what it did without being focused on deliciousness. Yes, we've got all the science there. As a matter of fact, the science that we just shared on those vegetable oils is in the Eat Smarter Family Cookbook. There's over 250 peer-reviewed scientific references embedded into the book in a fun and beautiful way. But also when it boils down to it, it's really about the delicious recipes. There's a hundred incredible recipes and something for everyone, absolutely. But listen, from what I'm seeing, this book is making its way into people's kitchens and it's just staying there, all right. So we're seeing pictures all over the place of people getting the Eat Smarter Family Cookbook and it just becomes a staple in their kitchen. There's so many delicious things to make from that book. And right now, you can actually get your hands on the Eat Smarter Family Cookbook as a free gift with the New Year, New You Superfood Bundle from Organifi. The Superfood Bundle has three components. One focuses on energy, the other focuses on recovery, and the other focuses on a radiant appearance, which includes healthy skin. For energy, you get the Organic Red Juice Superfood Blend. In addition to this berry blend, which includes blueberries that have been found to directly target fat cells, and this is according to researchers at the University of Michigan, one of their other ingredients used in the Red Juice Blend is beets. And a study published in the journal Applied Physiology showed that beet juice boosts stamina up to 16% during exercise and training. So the Red Juice Blend is all about energy and kids love it as well. It's one of my family favorites for sure, and it's been a huge upgrade to the Kool-Aid paradigm that I grew up in, and I know that you probably grew up in as well. Kool-Aid and their Flavor-Aid. Kool-Aid is already cheap, but if you didn't even have Kool-Aid money, we got Flavor-Aid. And now, in addition to that, so we've got the Red Juice Blend in this incredible bundle for this new year, but we've also got the Gold Blend. And the Gold Blend is centered around the power of turmeric, and it's an incredible turmeric latte. And in particular, a study that was published in the European Journal of Nutrition uncovered that compounds in turmeric can down-regulate inflammatory cytokines and up-regulate the activity of adiponectin and other satiety-related hormones. And turmeric has been well-established to improve insulin sensitivity, reduce blood fats, and directly act upon fat cells. And in addition to this organic turmeric blend, there's also things like Reishi Medicinal Mushroom and cinnamon and other incredible ingredients that have been documented through peer-reviewed studies to improve our sleep quality and improve cognitive function and recovery. And finally, in this amazing bundle, for a radiant appearance, in particular for healthy skin, and it's derived from the very best and most bioavailable sources there really isn't any collagen better in the world than Organifi's Collagen. Now, a study published in the journal Dermatology Practical and Conceptual titled Collagen Supplements for Aging and Wrinkles: A Paradigm Shift in the Fields of Dermatology and Cosmetics. This was just published in 2022, affirming collagen does in fact work at preventing and reducing the signs of aging of our skin. Improving the elasticity, reducing the appearance of wrinkles, and there's this huge component that often isn't given a name, but we talk about the glow of the skin and this kind of radiant appearance of the skin. Collagen is critical in that. And so you get all three of these incredible superfood blends, Organifi's Red Juice blend, their Gold blend, and their Collagen blend, you get all of these together for 15% off, plus they're going to give you a free physical copy they're gonna send to you of the Eat Smarter Family Cookbook, the USA Today National Best-Selling Book for free.

This episode is brought to you by Onnit. One of the ways that Ed and I connect is our love of fitness, our love of training our bodies so we can show up stronger and more resilient in our day to day lives. And for me, it's all about practicality and understanding things that are going to happen in our lives that are going to be obstacles in our goals to getting to the level of fitness that we want to get to. So we can have aspirations of going to the gym every day or going on a hike or going for a walk every day. But stuff happens. Life happens. Things come up. And so over the years, I've been collecting different pieces of fitness equipment, different tools, low-cost tools that I always have on hand when plans change and I can't get to where I want to get to. So I always have something at home and also for my family to utilize as well. And so this is why I'm such a huge fan of unconventional training, not just the typical push-pull methods of training, but being able to focus on all of these remarkable stabilizer muscles and having a level of tone and definition that you typically don't see with people in my age bracket, for example, but also the functionality and being able to express myself in all these remarkable, creative, fun ways. Because we want to be able to continue playing and having fun as we age as well. And a big part of that, for me, has been utilizing unconventional training with the fitness tools from Onnit. They are the company that brought steel clubs and steel maces and their incredible primal kettlebells to the market. Things that have become popularized with other companies. Onnit is the originator. They've had partnerships with Marvel, with Star Wars, like you just can't partner up with companies like that, but it's because they are the real deal. They are the industry leader when it comes to utilizing these tools. And also they have top tier science backed. Literally, they run some of their supplements through double-blind placebo-controlled clinical trials, and they're based on earth-grown nutrients. So their Shroom Tech pre-workout has been run through a placebo-controlled clinical trial, and it is proven to increase your stamina, to increase your bench press and squat reps. It is truly remarkable. And the same thing holds true with their nootropic alpha brain. And so not only do they have steel clubs, steel maces, and their primal kettlebells, and so many other pieces of incredible fitness equipment that again, I highly recommend you pop over there and grab yourself at least one of these fitness tools to utilize this year. Add something to your repertoire, but also they have the very best human performance supplements that you're going to find. And you get everything that I just mentioned for 10% off store wide when you go to on onnit.com/model, that's onnit.com/model, upgrade your dedication to fitness, get yourself one of these pieces of equipment to have on hand at your home. And also they're fun. And they're amazing to be able to utilize. You could do sometimes dozens or even over 100 different exercises with some of these pieces of equipment. It's truly remarkable. And also again, incredible nutrition as well. So check them out onnit.com/model. This episode is brought to you by Pique Tea. Whenever a special guest comes into the Model Health Show studio, everyone is offered some of the most health-affirming and nourishing teas for them to sip on. Now, whether that's matcha green tea or one of my favorite teas, which is the fermented tea called pu'er. It's all about creating an environment for health and wellness within the body. In particular, when it comes to pu'er, it's about creating an environment of having a healthy microbiome. A study published in the Journal of Agriculture and Food Chemistry found that pu'er is able to potentially reverse gut dysbiosis by dramatically reducing the ratios of potentially harmful bacteria and increasing ratios of beneficial bacteria. One of the major ways that pu'er is able to do this is its high concentration of polyphenols that are remarkably beneficial for our gut flora. Now, the only pu'er that I drink and that I offer to my special guests is the fermented pu'er that utilizes a cold extraction technology making this pu'er at cold to low temperatures for up to eight hours. And this patented process gently extracts the natural antioxidants and polyphenols specifically and provides them in a way for maximum efficacy. And it's wild harvested. So this is beyond organic, making it even more rich in polyphenols. Plus it's triple toxin screened for one of the highest levels of purity. These are the teas from Pique Life. Go to piquelife.com/model. That's P-I-Q-U-E-L-I-F-E.com/model. And you're going to get up to 15% off their incredible fermented pu'er plus free shipping and other bonuses like free tea samples with some of their pu'er tea bundles.

He knows that his ability to express, his ability to serve, his ability to reach his highest potential and to stay at a high vibration has a lot to do with how he's taking care of his body. And one of the things that him and I are both big fans of is utilizing superfood concentrates. And one of my favorite superfood concentrates is a blend of the most powerful super-fruits. In particular, red, blue, that hue. That is an indication of certain antioxidants that have remarkable benefits. For example, Acai has the highest orac value meaning its concentration of antioxidants of any of the popular fruits that you see in the produce aisle at any conventional grocery stores. Now, Acai has an orac value of over 100,000. That's about 10 times more antioxidants than common fruits. And how does that show up? Does it actually translate over for our bodies? Well, a study published in the Journal of Agriculture and Food Chemistry found that Acai does in fact raise participants' antioxidant levels, demonstrating how effectively it is absorbed by our microbes, by the human gut. Our bodies really do vibe well with Acai. That's why it's popping out here on the streets right now. But we want to make sure, again, that it's organic. And these superfood concentrates. What if you blend Acai with, for example, blueberry, which researchers at the University of Michigan published data affirming that blueberries can actually affect genes that are controlling our ability to burn fat. Plus, combine that with the power of something that's well documented to increase our endurance. A study published in the Journal of Applied Physiology found that beet juice is able to increase stamina of study participants 16% during exercise. These are just some of the ingredients, the superfood ingredients in the Organifi red juice formula. It is free of conventional sugars. It's all organic. This is great for the kids. Kids really like Organifi red juice as well. It's a huge upgrade from the conventional Kool-Aid and Flavor Aid that many of us grew up with. This is a way to get all of these incredible nutrients infused into our bodies, into our cells by enjoying something like organifi red juice. Head over to Organifi.com/model and they're going to give you 20% off their incredible red juice blend. Go to organifi.com/model.

He's been an advisor and consultant to the Breaking 2 and INEOS projects with Eluid Kipchoge and professional endurance athletes including Paula Radcliff. Professor Jones gives his understanding of the evidence of the performance effect of the so called “super shoes” and whether they explain the recent pro marathon runner excess performance and if so, by how much. Amateur marathon runners may find interesting our exchange about the Boston Marathon and how it is getting harder to get into, and what amateur marathoners must do to enhance performance in order to qualify and get into the Boston Marathon today. Professor Jones gives his perspective on the popularized notion that when it comes to marathon training “volume is king” and if not, what would be the alternative. We talk about distance runners that are getting older, and how Professor Jones recommends changing training, if at all, for those looking to remain competitive. Finally, we talk about science and evidence-based nutrition protocol throughout the training cycle and pre-race and race nutrition.

Long-time listeners to the pod will know that Ed never ever talks about his swimming hobby, but the RTBC team have decided to indulge him - just this once, mind - and dedicate a *whole episode* to the boom in outdoor swimming. Whether you're a seasoned wild swimmer, a winter dipper or a lido goer, there's a huge number of reasons why you might like to step outside the indoor confines of your local swimming baths. We speak to Kate Rew and journalist - and former Hampstead Ponds lifeguard - Nell Frizzell about why they find outdoor swimming exhilarating, as well as how to avoid swimming in s**t. And Professor Mike Tipton is back to give us a health warning and plenty of advice on how to swim safely.Plus: How should Geoff navigate the annual rotting gourd display?GuestsKate Rew, Founder, Outdoor Swimming Society and author of the Outdoor Swimmers' Handbook (@kate_rew)Professor Mike Tipton, Professor of Human and Applied Physiology, University of Portsmouth (@ProfMikeTipton)Nell Frizzell, Journalist and Author of The Panic Years, Square One and Holding the Baby (@NellFrizzell)More informationCheck out the work of the Outdoor Swimming Society, including articles on how to stay well swimming and the 3% access mythBuy a copy of the Outdoor Swimmers' HandbookWatch a video of Mike immersing Chris van Tulleken into 12 degree waterMike mentioned the Blue Tits swimming groupThe Acta Physiologica article 'Effects of cold water on stress, cardiovascular and psychological variables'Check out Nell's books and her essay about being a lifeguard at the Hampstead Ponds Hosted on Acast.

What does it sound like when a young researcher meets one of his science heroes for the first time? Listen to this episode of The AJP-Heart and Circ Podcast to find out. Associate Editor Dr. Keith Brunt (Dalhousie University) interviews author Dr. Holger Burchert (University of Basel) and leading expert Dr. William Stringer (Lundquist Institute at Harbor-UCLA Medical Center) about a new Methods and Resources article published by Burchert and Klimpel as part of the recent Call for Papers on Exercise, Physical Activity, and Cardiovascular Health. The article by Burchert et al. is an important contribution of methodological advancement built upon a foundation of established literature, dating back to Fick's Principle, which first appeared as a two-paragraph conference abstract published in German in 1870 and later translated by The New England Journal of Medicine in 1948. Fick was the first to realize that cardiac output is equal to oxygen consumption divided by the arterial mixed venous oxygen content difference, allowing the first accurate determination of cardiac output. While non-invasive measurements of oxygen consumption and heart rate are now routine, sampling arterial and mixed venous blood is inherently challenging. This makes finding non-invasive techniques for these measurements incredibly important. Enter the OG of the linear method for determining the arterial mixed venous oxygen content difference, Dr. William Stringer. In his seminal 1997 article published in the Journal of Applied Physiology, “Cardiac output estimated noninvasively from oxygen uptake during exercise”, Dr. Stringer found that the arterial mixed venous oxygen content difference during incremental exercise can be estimated because it behaves in a predictable, linear fashion, thus avoiding the difficult blood sampling. Reading the article by Stringer et al., which was referenced in the CPET (cardiopulmonary exercise testing) machine manual Burchert used during his PhD work, sparked Burchert's interest to investigate the literature and ultimately build on Stringer's methodological approach by collaborating with this former school friend Dr. Fabian Klimpel. Burchert et al. found that a 3rd order polynomial S-curve described the arterial mixed venous oxygen content difference slightly better. More importantly, the authors also determined that the inflection point of this function could be related to the first ventilatory threshold and the inflection point of the oxygen dissociation curve. Why is this important? A deeper understanding of the mechanisms behind the s-shaped response has potential clinical translation, as the method could be further developed by tailoring it to individual patients. Listen as we discuss why it is important for early career researchers “to look back in order to look forward,” to use collaborators from other disciplines to support thinking creatively about cardiovascular physiology, and to align with mentors who facilitate young careers through constructive peer review and publication.   Holger Burchert and Fabian Klimpel Revisiting cardiac output estimated noninvasively from oxygen uptake during exercise: an exploratory hypothesis-generating replication study Am J Physiol Heart Circ Physiol, published August 25, 2023.

You've been hitting the gym regularly, maintaining a balanced diet, and following all the best advice from your favorite health gurus, but you're not quite seeing the results you've expected. Have you ever thought, "Is it just my genes?" Have you ever told someone else that your current state of health is just genetic? If so, you're certainly not alone. I heard it all the time when I worked on-on-one with clients as a personal trainer. Many people question why they can't bulk up or slim down as quickly as their friends or why some people can eat all they want without gaining a pound. Is it truly down to genes, or is there more to it? In this article, I will guide you through the complex interplay between our DNA and our fitness levels. By the end of this read, you'll have a newfound understanding of why we are the way we are and, more importantly, what you can do about it. Together, we'll explore fascinating scientific research and dive into topics like how genes can influence physical traits relevant to fitness, the impact of genetics on how our bodies respond to exercise, and the never-ending "nature vs. nurture" debate. Genetics and Fitness 101 You might've breezed through high school biology, nodding along when the teacher mentioned DNA, genes, and chromosomes. But let's face it, back then, you probably didn't imagine you'd be revisiting the topic in the context of your gym routine. So, let's roll up our sleeves and demystify the relationship between your genetics and fitness. The Basics of Genetics First things first: What exactly is genetics? At its core, genetics is the study of genes, the segments of DNA that provide the instructions for making proteins in our bodies. Think of your genes as the blueprint, the original plan that determines everything from your eye color to, yes, certain aspects of your fitness profile.Ridley, M. (2006). Genome: The Autobiography of a Species in 23 Chapters. Harper Perennial. Every cell in your body contains DNA, and every DNA molecule comprises two strands that twist together to form a shape we often refer to as the 'double helix.' This DNA is broken down into units called genes. Imagine your DNA as a cookbook and genes as individual recipes. They dictate how things should be constructed and function. How Genetics Can Influence Fitness Levels Now, the juicy part: how do these genes affect our fitness? Your genes can influence many factors related to your physical capabilities. For example, a study published in the Journal of Applied Physiology found that individuals with certain genetic markers were more predisposed to have a higher percentage of slow-twitch muscle fibers. These fibers are essential for endurance sports like marathon running.Costill, D. L., Daniels, J., Evans, W., Fink, W., Krahenbuhl, G., & Saltin, B. (1976). Skeletal muscle enzymes and fiber composition in male and female track athletes. Journal of Applied Physiology, 40(2), 149-154. Conversely, some genetic markers indicate a higher percentage of fast-twitch muscle fibers. If you've ever marveled at the explosive power of sprinters or weightlifters, you can bet that fast-twitch muscle fibers play a significant role in their prowess. Real-life Examples of Genetic Factors Affecting Fitness To make this even clearer, let's discuss some real-world examples. Have you heard of the ACE gene? Research published in the European Journal of Applied Physiology points to the fact that individuals with a specific variant of the ACE gene might have an edge in endurance events. On the other hand, a different variant of the same gene is linked to strengths in power and sprint activities.Myerson, S., Hemingway, H., Budget, R., Martin, J., Humphries, S., & Montgomery, H. (1999). Human angiotensin I-converting enzyme gene and endurance performance. European Journal of Applied Physiology, 80(3), 224-230. Another interesting gene is ACTN3. This particular gene has been dubbed the "sprint ...

Welcome to the PT on ICE Daily Show. Happy Friday morning. Hope your Friday's off to a great start live here on YouTube and Instagram, everywhere you get your podcasts. My name is Alan. I'm happy to be your host today. Currently have the pleasure of serving as the chief operating officer here at ICE and a lead faculty in our fitness athlete division here on Fitness Athlete Friday. We consider it the best start day of the week. We talk all things CrossFit, Power Lifting, Olympic Weightlifting, endurance athletes, running, swimming, cycling, all that sort of thing. So if you're interested in working with the recreationally active patient or client, Fridays are for you. We're going to talk all things heat based recovery today. We spent two weeks ago talking about cold based recovery. So it'll be a nice change of pace on the opposite side of the spectrum. Before we get started today, first of all, I want to say big thanks to our friends at FIRE, Foraging Youth Resilience for having Jeff, our CEO, and myself out this week to their annual camp outside of Boulder, Colorado. Huge fun getting to know a lot of the kids, the campers, as well as a great network of coaches, games athletes, all sorts of wonderful people from the CrossFit space coming together to help support FIRE. It was great to meet everybody out there. If you want to learn more about FIRE, you can read more on their website. We're big supporters of FIRE here at ICE. So you'll continue to see us have more opportunities to help get involved with FIRE and support FIRE as time goes on. Some courses coming your way from us in the fitness athlete division. If you're looking to catch us out on the road for clinical management in the fitness athlete live, that's our two day live seminar. Your next chance will be September 9th and 10th. That's going to be out in Bismarck, North Dakota with Mitch Babcock. And then you can catch the same month at the end of September, September 30th and October 1st out on the west coast. Zach Long, aka The Barbell Physio, will be out in Newark, California. That's in the Bay Area of California. And then online, our clinical management fitness athlete essential foundations, our eight week online entry level course into the clinical management fitness athlete curriculum. That will start September 11th. That's taught by myself, Mitch Babcock, Kelly Benfee and Guillermo Contreras. And then the next week after our level two online course, clinical management fitness athlete advanced concepts start September 17th. So you can learn all about that at ptenice.com. That's where everything lives that you want to know about ice. So today's topic, heat based recovery. We have talked about cold based recovery, specifically two weeks ago here on fitness athlete Friday. We talked everything regarding cold plunges and cold based recovery. We're going to go to the opposite side of the spectrum now and talk about heat based recovery. So the big summary from if you didn't catch us two weeks ago, the big summary from cold plunging is that we really want to avoid it after exercise. It seems to really have an effect on that post exercise inflammation effect that we want to build strength, build hypertrophy. It does have some benefits, but we mainly want to avoid it after exercise. You're going to see a recurring theme here with heat based recovery. But I do want to start by first of all, defining what is heat based recovery, talking about the differences between things like hot tub or whirlpool. Differences between you may have questions about infrared versus traditional sauna. And then I want to talk about some of the research supporting the use of heat based recovery, but also the application of it both in the clinic. And when you're discussing these topics in the clinic or the gym with your patients or athletes. So let's start first by defining it. What is heat based recovery? We have a couple different types. The first is what we'll call hot water immersion. This is basically the opposite of cold water immersion or cold plunging. This is where you get in a hot tub or a hot bath or a whirlpool machine, some sort of hot water immersion. Now defining temperatures here is really important. We did that two weeks ago with cold water immersion. Really important to note that at least from the research, we have specific temperature ranges that we're discussing with all of these modalities. And we're also assuming that you have your whole body immersed in something like a sauna. Or that if you're in hot water, for example, a hot tub or a hot bath, you're immersed at least up to the level of your neck. A lot of what we're going to talk about doesn't apply to you if you're somebody that just sticks your your foot in the hot tub. Or doesn't otherwise get fully immersed in whatever modality you're using. So two different types of hot water immersion, hot tub or hot bath. When we're at home and we run a bath, when we look at what is the temperature of what the average human being might consider quote-unquote hot. A hot bath is right around 100 degrees Fahrenheit. And that your average hot tub is not too different. A hot tub that you might get into is going to be somewhere between 100 to 110 degrees Fahrenheit. But now when we look at this from a research perspective, it's usually tightly controlled and it's usually tightly controlled a little bit hotter. So when they look at hot tub whirlpool type immersion in the research, they're looking specifically at a temperature range of about 110 to about 120 degrees Fahrenheit. So if you're somebody that really hates a hot bath, if you run a hot bath and you wait for it to cool down a lot, then just know this is going to be on the upper end of your temperature comfort. Why this matters is that when we add that that circulating bubble component to a whirlpool, to a hot tub, it seems with the water continuously moving that it makes that hot water immersion just a little bit more tolerable and therefore they bump the temperature up a little bit. Again, 110 to 120 degrees Fahrenheit. And again, immersion in a hot tub whirlpool up to the level of the neck. Now duration is really important. We talked about that with cold plunging. That if you're somebody that gets in for a minute, you probably don't have to worry about the positive or the negative effects because you're really not doing it. The same is true here. When we look at hot water immersion, when we talked two weeks ago, we talked about humans have a really great tolerance for heat at rest. We can sit outside 70, 80, 90, maybe even 100 degrees, especially if we're in some shade and we can be okay. We don't have a great tolerance for cold at rest. And we see this carry over into hot water immersion that because we're so much more tolerant to heat, we see duration for hot water immersion a lot higher. We often see duration 15 to 30 minutes in a whirlpool in a hot tub. Maybe you've been at a hotel or a resort or something. You've seen that sign. We've all seen that sign on the hot tub. You know, don't stay in here too long. Max time 20 minutes, 30 minutes. That tends to be our tolerance for hot water immersion. So somewhere between 15 to 30 minutes, but definitely longer than what we're used to seeing with cold water exposure where the general recommendation usually never exceeds 10 minutes. Now getting into sauna, temperatures are going to go up. We're no longer actually sitting in water. We're usually sitting in a room that is either steam heated or dry heated. Those also have different temperature parameters when we look specifically at how they're studied in the research. Traditional sauna, whether it's dry or a steam sauna, is a lot hotter. 150 to up to 220 degrees Fahrenheit. Infrared sauna is going to be lower, 120 to 140 degrees Fahrenheit. And again, the duration for sauna is going to be higher, a lot like hot water immersion. Somewhere between 30, maybe even to a 90 minute dose, and that's going to be mostly for infrared sauna. That would be really tough to do in a traditional sauna. So that's how we define hot water immersion and also what we would call just sauna, sauna protocol, traditional or infrared. Now the research. I want to share a couple of different papers with you as we get into talking about what does the research support? What does it not support? Talking back to hot water immersion. So again, our hot tub or our whirlpool protocols. A great paper from 2022, the Journal of Sports Science. More and more Gamino and colleagues, pardon me butchering that, looking at hot water immersion. They took folks and they had them sit in a whirlpool for 15 minutes at 110 degrees Fahrenheit. They also had another group sit in a cold plunge at 50 degrees Fahrenheit and they compared outcomes on the quadriceps muscle. They wanted to look at specifically the contractile properties of the muscle itself and found that the group sitting in the hot water after exercise had increased contract properties of the quadricep muscle compared to the folks who did cold water immersion and compared to the folks who did nothing, who sat at a room temperature room. So the the effects of hot water immersion appear to have a more beneficial effect on our muscle and we'll get more into that as we get more into the research. My next paper, really old. I love some of these old papers that just show how long we've been studying this stuff. Francisco and colleagues back from 1985, so before I was even alive, Journal of Applied Physiology. Looking at the use of hot water immersion and comparing it to basically an active recovery protocol. So two groups of subjects, one group exercising at 60% of their VO2 max. So essentially an active recovery spin on a cycle or a really really really low slow jog, something like that. To a group that did an hour in a whirlpool at 105 to 110 degrees Fahrenheit. And then they did a crossover here. So they took both groups and then flipped them a couple of days later and had them repeat the same thing. What they found in the group who sat in the hot tub for 60 minutes is they had an almost identical cardiovascular change. So they had an increase in their cardiovascular output and their mean arterial pressure, which just kind of tells us that there is a cardiovascular demand on the body when you are exposed to heat that mimics low-level active aerobic recovery type exercise. So what does that tell us? That tells us that first of all if we are looking for a recovery day that a longer hot water immersion or maybe a sauna can be a viable option in place of a recovery workout that we're going to get some increased cardiac output. Our heart rate is going to elevate. We know being exposed to heat we're definitely going to sweat. That's going to come on board no matter what. But we're going to see blood pressure changes as well. That tells us we're kind of getting a flushing pumping effect when we're exposed to heat specifically in this study hot water immersion compared to if we went to the gym and just spun on our bike or went for maybe a really long walk or a really slow jog or just some sort of active recovery exercise that they appear about equal. Which is great if that's what we want. If we're trying to limit cardiovascular load, if we're trying to limit volume on our body then we need to be mindful that a longer duration hot water experience can have that effect on us. So it appears to be about an equal effect, which is nice. The next study here, Borg and colleagues from 2020, the International Journal of Sports Physiology and Performance, looked at hot water immersion versus cold water immersion versus control. Specifically they had these folks do these modalities after cycling in what they called hot weather, 75 degrees Fahrenheit. So they went for a long bike ride in the heat and they came back. They threw one group in cold water immersion in the cold plunge. They threw one group in hot water immersion, a whirlpool, and one group just sat at room temperature. And they found that those exposed to the hot water immersion were more likely to report that the session they had just performed, the cycling session in the heat, was easier. And they also had a lower cardiovascular response to those who had a cold water immersion. So it seems like when we're cooling down we want to choose heat as it's easier on our body, easier on a cardiovascular system than finishing a hot workout in the heat. It sounds great. We've all had those workouts. I just had one two weeks ago where we literally want to stick our head in the sink, which is exactly what I just did, and just cool down our head. That seems like what we want to do, but we know that can have sort of a shocking effect on the body compared to if we ease ourselves out of the heat with maybe not exactly what we just did in the heat, but we choose something that's going to feel temperature neutral compared to what we just did, which was a really tough workout in the heat. Heat exposure after exercise, especially in the heat, seems to have a beneficial effect as we're trying to cool back down to baseline. Now switching gears and looking at the sauna research. So this is just as popular as everybody wants to know about cold plunges. Everybody wants to know about sauna protocols. If you listen to anything about Andrew Huberman, you have been blasted with more information than maybe you've ever wanted to know about the sauna. But I want to pick just a couple papers here looking at sauna exposure, specifically after exercise. So Bezoglav and colleagues 2021 International Journal of Environmental Research and Public Health. This is a great study. This doesn't actually research anything on sauna protocols itself. I love this study. This is basically a patient expectation, an athlete expectation of what athletes expect will help them recover and what they actually choose when they are performing their recovery. And it's just really important to know this paper in the back of your head. That 97% of athletes surveyed use sauna as their number one choice for recovery. So that's really important for us to know. We have to be able to speak intelligently about good, bad pros, cons about sauna with our athletes knowing that 97% of them are thinking I'm not feeling great. I'm feeling banged up. I am going to choose sauna as my number one recovery protocol. And we know this from physical therapy research. Massage is also popular. Not surprising. It's popular with athletes. 87% of athletes choose massage as their secondary recovery protocol. And then 80% choose taking a nap, third. So in that order, sauna, massage, and napping. So that's a really important paper to know. Miro and colleagues from 2015 in Springer Plus. This is an online open access journal. Looked at comparing folks doing infrared sauna, traditional sauna, after performing either hypertrophy focused resistance training for 60 minutes or endurance training. So they basically wanted to create a bunch of muscular damage and then have folks either get in an infrared sauna or traditional sauna. This study also had a crossover design. So the objective outcome here was a counter movement jump test and then also effects on the cardiovascular system. So that traditional sauna was performed at 122 degrees Fahrenheit for 30 minutes. The traditional sauna was performed at 70 degrees Fahrenheit for 30 minutes. And again, both groups exercise really hard for an hour. The traditional sauna group saw a reduction in performance on the counter movement jump after sauna protocol compared to the group using the infrared sauna. The traditional sauna group also had a significant spike in their heart rate. About 30 to 40 more beats per minute resting while sitting in the traditional sauna than the group sitting in the infrared sauna. So again, like we talked about a couple papers ago with environmental exposure, it seems like using sauna, specifically a really hot traditional sauna after exercise, seems to have a negative impact on our system. Of it's just too much heat load, it's too much cardiovascular load. It can lead to both negative performance outcomes, but also negative physiological outcomes. Supporting that, Skorsky and colleagues from 2019 International Journal of Sports Physiology and Performance. This group was looking specifically at performance. They had swimmers perform 4x50 meter sprints. I don't know anything about swimming. I assume that's a tough thing to do to do 4x50 sprints. Afterwards, the swimmers were either put in a group where they sat passively at room temperature. For 25 minutes or they did three eight minute rounds in the sauna, a traditional sauna at 185 degrees Fahrenheit. And then they had those athletes come in the next day and repeat the 4x50 swim performance. All of the subjects who used the traditional sauna after the sauna reported a stressful experience, both physically and mentally. And then the next day all of them had impaired performance when they went to repeat the 4x50 swims compared to the group that sat at control. They obviously did not report sitting at room temperature as a stressful experience. And they all performed better at the 4x50 than the sauna group. So it appears that longer duration, hotter traditional sauna seems to have a more negative impact on recovery. So what does this tell us? What does all this research tell us? How can we apply this with our patients, with our athletes, when they're asking questions about sauna? Maybe they're already using a sauna protocol. So as we talked about two weeks ago, cold water immersion, cold plunging appears to have a really negative impact on performance and recovery when used directly after exercise. Compared to hot water immersion, whirlpool, hot tub used after exercise. And it also really seems to affect our ability to adapt to the heat. So the takeaway here is that if we're just finishing exercise, maybe traditional sauna, especially for a longer duration, especially for a higher heat duration, is maybe not the modality of choice. Just like a cold plunge is maybe not the modality of choice. Which is not to say we can't use heat as recovery modality. But if we're thinking we just finished training, we should look towards that hot tub. We should look towards that whirlpool. We should maybe look towards that active recovery. And we should save a really long, hot traditional sauna or a cold plunge for maybe before training earlier in the day. Or what we don't have research on yet is what is that window? How much time difference between training and using a really hot sauna or using a cold plunge is still going to allow us to feel better recovery wise but not have those negative effects on performance. We don't know that yet. But for now what we can recommend is stay away from that cold plunge. Stay away from that really hot, long duration traditional sauna about right after training. Give yourself a gap. Again, we don't know how long. Or do it earlier in the day sometime before you actually start your exercise protocol. We do know that both hot water immersion and infrared sauna offer cardiovascular effects that are similar to active recovery. So if we really are not feeling like exercising today, if we're really feeling like we need a day off, we can still have some positive health benefits from going and getting in the sauna. Especially something like an infrared sauna or sitting in a hot tub for maybe 10 to 30 minutes. But we really need to consider avoiding that long duration traditional sauna. It appears to have a big effect on our cardiovascular system. It's adding a training load. It's adding a heat load to our body that's going to cause our body to need to adapt to that stress. So big term takeaways. There's no shortcut, right? What we're seeing in the research with both cold water immersion and hot water immersion, there's no shortcut here. We need to allow the body's natural inflammatory response to the exercise that we just did occur if we want to reap the benefits of that occurring. Yes, these things can help us feel less sore. Yes, they can help us feel less fatigued. But if we use them too much, they do seem to have a long-term detrimental effect on our performance. Which kind of defeats the purpose of going in and doing a hard workout, a long run, a long bike, a long CrossFit session, a long weightlifting session, whatever you're doing. If we chronically use these things, yes, we might feel better. But we need to be concerned that maybe we're leaving something on the table as far as strength, as far as hypertrophy when we use these kind of extreme temperature modalities, cold plunging, really really hot sauna. I could imagine that one study that showed a really detrimental effect was only 185 degrees. Some traditional sauna protocols in the 200s. I know Jeff Moore does the sauna at 205 degrees, I think for 15 minutes, which is even more of a heat load than 185 degrees. So just be aware of that and understand how to speak about these things with your patients and athletes because they're going to have questions about it. Remember that paper? 97% of people look to sauna is the first choice for a recovery modality and then massage and then taking a nap. So 97% of people could use probably more education on sauna because we know they're thinking about using it. So I hope this was helpful. We have an entire week in clinical management fitness athlete essential foundations dedicated to this now. We talk all things nutrition, sleep, we talk cold water immersion, hot water immersion. We also talk about compression therapy. So things like massage, massage guns, cupping, all that sort of thing. We discuss all of that research that your athletes, your patients want to know about when they come into the clinic and ask about recovering from exercise. So I hope you have a wonderful Friday. I hope you have a fantastic weekend. Thank you for joining us. Have a good day. Bye everybody. 22:33 OUTRO Hey, thanks for tuning in to the PT on Ice daily show.

On the first day of January, people all over the world dive into the water as a way to start the new year fresh. It's often referred to as a “polar plunge”. But cold water dipping is different.It's not a breathless in-and-out plunge, but a slow submersion: lingering in the cold water for 5 or 10 minutes. No wetsuit. This fall, Outside/In producer Justine Paradis got to know a community of dippers along the coast of Maine. Many of them described something happening once they're in their water.. Something which they say changes their relationship to the cold, the ocean, and themselves. In this episode, we're ringing in the new year by sharing a little more from those conversations.Featuring Kelsy Hartley, Caitlin Hopkins, Puranjot Kaur, Betsy Dawkins, and Judy Greene-Janse. Thanks to everyone who sent in suggestions for winter surthrival. We featured ideas from James in Bend, Oregon; Kyra in Edmonton, Alberta, Canada; and Annie in Portland, Maine. Thanks also to Gin Majka, Guenola Lefeuvre, and Annie Ropeik. A word on the risks of cold water immersionPeople engage in cold water dipping and swimming around the world. Many claim health benefits, like a boosted immune system and reduced inflammation. But it's not a risk-free activity. "I'm not sitting here as the fun police stopping people doing what they want to do. It's just we would encourage them to do it safely,” said Mike Tipton, a professor of Human and Applied Physiology at the Extreme Environments Laboratory at the University of Portsmouth. He shared a couple risks to consider before jumping in.Cold shock response, which occurs as you enter cold water and lasts a couple minutes. This prompts an involuntary gasp and hyperventilation – bad news if you're underwater or in choppy water.Cardiac triggers. Cold water shock sends a signal to your heart telling it to beat faster, but face immersion tells your heart to slow down. These competing signals to your heart can potentially cause cardiac arrhythmia, especially when plunging and breath holding. On top of that, the cold water constricts your blood vessels, pushes up blood pressure, and makes your heart work harder.Swim failure, the result of direct cooling of the superficial nerves and muscles (especially in the limbs). This can occur before other effects of hypothermia. “This is where we see people swimming out to sea offshore, turning around and finding they can't get back because they become physically incapacitated… one of the obvious bits of safety advice is don't swim out of your depth and swim parallel to the shore, not away from it,” Mike said.A few basic safety tips: Don't go alone.As one cold water swimmer put it, “Keep your feet on the ground.”Get yourself checked for any pre-existing conditions that might be triggered by a sudden change in blood pressure. SUPPORTOutside/In is made possible with listener support.
