Let's unpack something most midlife women are totally missing – protein for Menopause Hormone Support. Are you feeling moody, low-energy, or constantly craving carbs in midlife? It might not just be your hormones—it could be your protein intake… and its effect on your hormones.  In today's episode, know how protein connects hormones and why your daily meals might be the hormonal tune-up you didn't know you needed. Cortisol & Protein: The Stress-Balance Dance Cortisol levels increase in response to low blood sugar or stress, which are common when meals are high-carb and low-protein. A high-protein diet blunts cortisol spikes post-meal and improves the body's stress response.   Insulin: Protein's Role in Glucose Control Protein stimulates insulin—but in a modulated way that helps with blood sugar stability, not spikes. In midlife and beyond, protein helps preserve insulin sensitivity, especially when combined with resistance training.   Ghrelin & Leptin: Protein vs. Cravings Ghrelin = your hunger hormone. Protein is the most effective macronutrient at suppressing ghrelin. Leptin = satiety hormone. Protein helps regulate leptin sensitivity over time. The Protein theory goes that if the body doesn't get enough protein it will message you it wants more. The problem is the message is not clear. It's just a hunger signal. You're left to figure it out or deal with the tempting cookies, cakes, and chocolate hidden in the icebox.    Estrogen: From Muscle Protector to MIA Estrogen is an anabolic hormone—it supports muscle maintenance, insulin sensitivity, and metabolic efficiency. As estrogen declines in perimenopause and menopause, its natural support of muscle protein synthesis (MPS) disappears. With estrogen no longer stimulating MPS, women must now rely on two primary tools to stimulate it: Resistance training Adequate high-quality protein (especially leucine-rich) “Estrogen enhances the anabolic response of skeletal muscle to both feeding and resistance exercise, and its loss results in anabolic resistance.”   More Truths About Protein for Menopause Hormone Support Muscle Protein Synthesis declines with age—and even more so without estrogen.  This is why RDA-level protein (0.8g/kg) is not sufficient in midlife - a statement agreed on by Registered Dietitians, longevity and geriatric experts alike.  Experts (ISSN) recommend ≥1.6–2.2g/kg of body weight for active women in midlife to maintain muscle, metabolism, and hormonal resilience.   The Anabolic vs. Catabolic Hormone Framework Anabolic Hormones = Build & Repair These are hormones that stimulate tissue growth and regeneration: Testosterone – promotes muscle growth, strength, libido Growth Hormone (GH) – supports repair, recovery, and fat metabolism Estrogen – helps preserve lean mass, regulates insulin sensitivity Insulin – can be anabolic by shuttling nutrients into cells, especially post-exercise Protein intake supports all of these by providing the amino acid building blocks needed for anabolic activity. Catabolic Hormones = Break DownThese are hormones that promote the breakdown of muscle, tissue, and energy stores: Cortisol – breaks down muscle for glucose during stress Epinephrine/Norepinephrine – mobilize energy in fight-or-flight Chronically elevated catabolic hormones + low protein = muscle loss, cravings, fatigue. Fat Storage Insulin isn't actually a catabolic hormone but it does increase fat storage. You can't be burning fat if insulin is high, as is true for many women. Focusing on boosting the anabolic hormones is the game-changer.    Other Episodes You Might Like: Previous Episode - Can We Just Stop the Self Sabotage to Feel Your Best Ever  Next Episode - How and Why to Consider Meditation in Menopause More Like This - Where Protein Recommendations for Women Come From?   Resources:  This episode is brought to you by Flipping 50 Longevity Pro Protein & Fiber, the simplest ingredient, cleanest, third-party-tested protein powder formulated specifically for midlife metabolism.

4 Exercise Mistakes Hijacking Your Menopause Fitness (and how to fix them)

You're doing it all but could there be hidden mistakes hijacking your menopause fitness. Increasing protein, lifting weights, doing high intensity… How can you be this active but not working?  Disclaimer: This could trigger you. The mistakes hijacking your menopause fitness you could be doing on purpose because you were told once this is what you SHOULD DO.  This episode is for all women, and for you. So let's unpack these mistakes hijacking your menopause fitness.  Before anything.. Measure.  If you aren't measuring your body composition - skeletal muscle mass vs. body fat—you won't truly know what's working. I'll link to the 4 Smart scales in my store. You can get a Dexa or go to a gym. #1 Not Consuming Enough Fuel Women are not the same as men on carbohydrate needs. We get little, we disrupt hormones. You are influenced by cortisol, insulin, thyroid, testosterone, growth hormone and the endocrine.   How much fuel do you need? Endocrine dysfunction - ~30-35 calories per kg of FFM in women; but around 15 calories per kg FFM in men. Fat Free Mass (FFM) - say you're 130kg and you have 25% body fat. You need 2923 kcals to keep your body functioning well.   Fueling Your Workouts: Cardio: 30g carbs and 15g protein before Strength: 15g protein before + 30-45g protein after (higher in and after menopause)    Thyroid & Carbohydrates Low carb diets (under 100g) - pivotal point for lower thyroid function.  Serotonin - produced in the gut, declines with low carb diets.  Low-carb diets - don't lead to better weight loss long-term, they cause water loss.   What Happens When You're Under-Fueled?Low Energy Availability from brain (hypothalamus) to body… Hypothalamus signals HPA axis dysfunction Adrenals releases cortisol Thyroid slows metabolism Body conserves energy and breaks down muscle instead of fat for fuel   When You Fast, try one of these: High intensity intervals  Lift heavy weights  High intensity boot camp class  Reduce carbs, maintain a keto-like diet while increasing your walks   Know the Sneaky Mistakes Hijacking Your Menopause Fitness #2 Never REALLY Recovering From Hard Intervals or Hard Workouts  Some bootcamps and spin classes are rapid, high-intensity intervals without adequate recovery. Your cortisol levels during this session accumulate.  It feels like you crushed it, but here's the truth: if you're not giving yourself real recovery, you're not hitting your peak.  When you skip the full recovery, you're not building the strength and power that protect against sarcopenia (muscle loss). Try these: Warm-up A:  Run up a steep hill for 40 seconds Mark that point on the hill Slowly go back down Fully recover, with your nasal breathing. Repeat until you don't make it to the same spot on the hill Warm-up B: Run up a steep hill for 40 seconds Mark that point on the hill Quickly make your way down Cool down within 60 seconds Immediately run up again Repeat until you don't make it to the same spot on the hill They both will feel hard, but only one gets you to your maximum capacity.  The glycolytic fibers - fast twitch that sustain power fatigue quickly. Women have fewer of them than slow twitch and lose twice as fast as slow-twitch fibers. Fast-twitch fibers need power moves — like heavy lifting or box jumps — and plenty of recovery to reload and go again.  You're fooling yourself into thinking you're getting in better shape.  So test yourself… a simple protocol you can do at home. Try a full test battery you can easily do at home - I'll provide access to it in the show notes as soon as it's ready.  Measure. Monitor your waist girth, your body fat percent and your skeletal muscle. Rate your energy, sleep, focus, digestion and elimination. Are you improving, worse or the same? When you're exercising optimally these things also improve. It's not just muscle mass and fat.    Are these Mistakes Hijacking Your Menopause Fitness?   #3 Relying on Caffeine, Bar Codes and Over Emphasis on Packaged Food By nature, your cortisol level is highest at about 8am. You've fasted overnight and if you're not eating soon after waking, especially if you're exercising as a female, your body has stressor on top of stressor: Punched your ticket in midlife (less estrogen, more cortisol) Caffeine (more cortisol)  No fuel (more cortisol)  Exercise (more cortisol)  Fuel before intense exercise.  Fuel again after, especially within the 24 hour period after resistance training or other HARD workouts the need for recovery persists, so it's not just that single meal following activity. #4 Always High and Hard You have never needed high intensity more in your life than whatever age over 40 you are now.  You also need full recovery … between intervals, strength training sets and sessions.  Here's the secret: Muscle gets stronger between sessions. The exercise is the stimulus. The recovery is where fitness happens – the release of hormones, the repair and supercompensation.  Recovery time. Get AT LEAST 48 to 72 hours between hard use of the same muscle groups. Active Recovery. The low intensity movement between your hard sessions is absolutely important in increasing circulation, blood sugar stabilization, improving sleep and mood and overall fitness levels.    Keep It Simple: Movement Time. Walking at the level below where cortisol negatively spikes so you can reduce or optimize it. Short & Intense. Spend small amounts of time in high intensity interval session - where you recover completely between sessions. All Major Muscle Groups. Spend 2-3 sessions a week hitting all major muscle groups or twice to total muscle fatigue. If you're in post menopause, the volume of sets has to be greater compared to a perimenopause woman. Recover. Give yourself at least 48 hours.. 72 is often BEST.  Resources: Flipping50 Membership Flipping50 Insiders Group   Other Podcasts You Might Like: Previous Episode - Is Red Light Therapy the Answer to Aches, Pains and More Movement?

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.

UND: - Was muss man dabei (noch) beachten? Den Rahmen dieser Episode bildet der "Schlagabtausch" zwischen zwei verschiedenen Arbeitsgruppen, die das für und wider polarisierten Trainings diskutieren. Wer am Ende die Oberhand behält und wie ihr die individuell "beste" TID findet, erfahrt ihr in dieser Folge.

In this MEGAphone episode we will be shouting out one of the most informative people to follow on social media that I know about, he specializes in power lifting and biomechanics and injury prevention and physical therapy. His Instagram handle is @SquatUniversity and his name is Dr. Aaron Horschig. As a physical therapist & strength coach, Aaron helps athletes move better, decrease their aches & pains associated with training, and find their true athletic potential.Dr. Horschig wrote an extremely informative and also controversial article that I love and want to share. This information addresses a well known injury protocol… A protocol that I used when I was an athlete in high school in college. A protocol that I used with clients and family members of mine when they got injured… A protocol that I believed in whole heartedly and taught every chance I could. A protocol my college courses taught me, straight out of the text books. It was simple… when you get hurt… the solution is RICE. Rest, Ice, Compression, Elevation. We all knew RICE.   And it turns out… we were all wrong. References: Dr. Aaron Horschig IG: @SquatUniversitywww.squatuniversity.com Book: Rebuilding MiloArticle Citations:1.    Mirkin G, Hoffman M.

Episode 100: Sexercise. Written by Valerie Civelli, MD. Comments by Namdeep Grewal, MD; and Hector Arreaza, MD. Have you ever wondered if sex is a good workout? Drs. Civelli, Grewal and Arreaza discuss the topic based on evidence offered by science. The following episode is not recommended for young children or people who consider sex a sensitive topic. This is the Rio Bravo qWeek Podcast, your weekly dose of knowledge brought to you by the Rio Bravo Family Medicine Residency Program from Bakersfield, California. Our program is affiliated with UCLA, and it's sponsored by Clinica Sierra Vista, Let Us Be Your Healthcare Home. This podcast was created for educational purposes only. Visit your primary care provider for additional medical advice.___________________________Sexercise. Written by Valerie Civelli, MD. Comments by Namdeep Grewal, MD; and Hector Arreaza, MD. A: If I say “bow chika wow wow” what's the first thing that comes to mind? The Chipmunks movie right?B: Yes, exactly, I can hear Alvin in his high-pitched voice, [higher tone] “bowchicka wow wow”. For those of you unfamiliar with this movie, don't feel too left out because even Alvin was hinting to exactly what you're thinking.A: Yep, we're going there today people.  Let's talk about sex.  Medically speaking of course. B: That's right because 1. If you're doing it, your risk for heart attacks and strokes are decreased after age 50 and 2. If you're not doing it, ask you're doctor, we should be discussing it and why not.A: Yes, that is the guideline-directed recommendation actually. We're recognizing more and more the importance of sexual activity in medicine and its impact on overall health, quality of life and even level of risk for mortality. However, given the sensitive nature of sexuality, few studies have been done to better correlate and define exactly what this means for our health specifically. Sex can be an embarrassing topic to discuss by patients, doctors and researchers which has been largely influenced by culture, religion and other societal norms.  Well, today let's break this proverbial glass. B: I agree, let's talk about sexuality activity and what research do we have.A: It has been said that Dr. Masters and Dr. Johnson were the earliest pioneers of this type of investigation. They published the first study of its kind in 1966, which examined the physiological responses of sexual activity. This was an 11-year observational study involving 382 females, ages 18 to 78, and 312 male volunteers, 21 to 89 years of age. The study identified a progressive increase in respiratory rates, up to 40 per minute, an increased heart rate 110 to 180 beats/min and an increase in systolic blood pressure by 30 to 80mmhg during sexual activity. In 1970, Hellerstein and Friedman identified the mean heart rate at the time of orgasm was 117.4 beats per minute with a range of 90 to 144. This was done in middle-age men, average age 47.5. Interestingly, the 24-hr ekg monitoring also identified a lower peak post coital heart rate, which was usually lower than the heart rates achieved with normal daily activities (around 120.1 beats per minute). In 1984, Bohlen et al. did a racier study with 10 couples using ECG, oxygen consumption (measured using a fast-responding polarographic O2 gas analyzer), heart rate and blood pressure monitoring before and during 4 types of sexual activity. This study obtained data during self-stimulation, partner stimulation, man-on-top and woman-on-top coitus.  The men were aged 25 to 43 years of age.  Results showed that self-stimulation increased the heart rate by 37 % from baseline to orgasm compared with a 51 % increase with man-on-top coitus. B: So already it was clear in 1966 to 1984 that physical exertion in the bedroom correlates to physiologic responses like increased heart rate, blood pressure, etc.  However, our question of the day is, does sexual activity count as exercise, and to that question we ask why or why not?A: When I think about exercise, I think about heart rate and blood pressure.  I think about indicators of energy expenditures and/or intensity. And specifically, while I'm working out…I'm talking about at the gym, and I'm running on the treadmill for example, my mental state is, how much longer until I can quit.  Duration and level of intensity while under this physical exertion feels most important. And according to the AHA, this has been heavily studied.  That's why 150 active intentional minutes of exercise are recommended per week to improve cardiovascular health. Does this translate to sexual activity? B: Well before we answer this, let's first mention the Bruce protocol. Have you ever heard of this? The Bruce protocol is a standard test of cardiovascular health, comprised of multiple stages of exertion on a treadmill, with three minutes spent per stage. Also at each stage, the incline and speed of the treadmill are elevated to increase cardiac work output, which is called METS. Stage 1 of the Bruce protocol is performed at 1.7 miles per hour and a 10% incline. Stage 2 is 2.5 mph and 12%, while Stage 3 goes to 3.4 mph and 14%. If you're a pilot for example, the FAA expects testing to achieve 85-100% of Maximum Predicted Heart Rate (220 minus your age) for a 9-minute duration.  With the Bruce protocol in mind, we circle back to our question of the day, does sex count as exercise?A: In 2007, Palmeri et al. reported that in 19 men and 13 women aged 40-75 years old, the intensity of sexual activity was comparable to stage II of the standard multistage Bruce protocol (moderate intensity) on a treadmill for men and stage I (low intensity) for women. In addition, maximal heart rate and blood pressure during sexual activity was approximately 75 % of that attained during maximum treadmill stress testing of the Bruce protocol. Collectively, based on these above studies, the physiological responses of sexual activity seem to be at a moderate intensity. B: Okay, so “you're saying there's a chance.” Right, one in a million Lloyd. Another movie reference, if you've seen the American classic Dumb and Dumber, you can appreciate it.  The point is, the level of intensity was identified by Palmeri's research but are we convinced sex may be used as exercise based on studies that were conducted more than a quarter of a century ago? As a studious, thriving resident physician, with a heavy background in research, I turned to Up to date for more data, and recommendations.  I had zero findings. Naturally I turned to Men's Health magazine to see what is out there to the general public:A: “You're in bed with your partner and you just finished a vigorous sex session. You're hot and sweaty, worked past that side cramp you got while thrusting, and are convinced you just burned as many calories as you would at the gym. You figure you can skip the treadmill today since your sex workout—a.k.a sex exercises, a.k.a sexercises—got you plenty of cardio.Well, we may have bad news: it depends on the type of sex you're having—specifically, how active you are during it, and how long you're having it—but unless you're really going at it for a couple of hours, odds are, it wasn't that great of a workout. To better quantify this, couples were evaluated while running on a treadmill for 30 minutes and compared to their sexercise. The results, which were published in the journal PLOS ONE, concluded that men burn 100 calories during the average sex session, while women burn about 69 calories. The researchers estimated that men burn roughly 4.2 calories per minute during sex, while women burn 3.1 calories. B: Men may be more physically active during sex which potentially explains why they burn more calories, study author Antony Karelis. But the main reason, Karelis told Time, is that “Men weigh more than women, and because of this, the energy expenditure will be higher in men for the same exercise performed.”It's also worth knowing that sex sessions in the study lasted an average of 25 minutes That's far longer than average. Times varied in the study, ranging from 10 to 57 minutes.  A: The longer the session, the more calories burned.  B: One study in the New England Journal of Medicine found that most sex sessions last six minutes. A: Here are some tips for burning more calories during sex:Make some moans and sighs to burn some extra calories.Change your position to make it more of a workout, especially women. If you're on top, move your hips like a belly dancer. It will feel good while giving you a workout.Experiment with a position where you squat on top of your partner and then bounce up and down. That's a great way to work out your thighs and rear.Try being on top rather than on the bottom, because research suggests that requires more energy.Kiss in unusual positions. Have the guy on his back. Do a push up on top of him. Come down to kiss him and then push back up.Take off your clothes in ways that burn calories. Draw it out and make it part of your foreplay. Or tease him as you get undressed. Do a seductive dance with a silk scarf, for example.Give a good massage to get your heart rate up. Ramp things up by going deeper. It's more sensual and works different muscles. Take turns so you can both get the calorie burn and its arousing impact. B: Harvard source:  During sexual intercourse, a man's heart rate rarely gets above 130 beats a minute, and his systolic blood pressure nearly always stays under 170. All in all, average sexual activity ranks as mild to moderate in terms of exercise intensity.  A: As for oxygen consumption, it comes in at about 3.5 METS (metabolic equivalents), which is about the same as taking a walk or playing ping pong. Sex burns about five calories a minute; that's four more calories used than watching TV. B: How do we decide if one is fit enough for sexual activity? For a 50-year-old man, the risk of having a heart attack in any given hour is about one in a million; sex doubles the risk, but it's still just two in a million. For men with heart disease, the risk is 10 times higher — but even for them, the chance of suffering a heart attack during sex is just 20 in a million. In short, if you are able to climb 3 flights of stairs, you are safe to proceed.  A: Circling back to exercise, keep in mind 4-5 calories burned per minute is still better than zero. Any time spent engaging in any level of physical activity is better than sitting on the couch.  B: Further, “Having sex for at least 10 minutes contributes to your cardiorespiratory health, increased serotonin levels (the happy hormone), and improved sleep,” Silberstang says. Studies have found that sex can relieve everything from anxiety and depression to high blood pressure.  A: When men orgasm, their bodies release serotonin, oxytocin, and prolactin, all hormones associated with better moods, relaxation, and lowered stress. Multiple studies have also found links between regular sex and a reduced risk for heart disease and prostate cancer, and a stronger immune system. One reason that sex isn't classified as a workout is due to its average duration: 3 to 13 minutes,” Silberstang explains. “So, naturally, one of the ways to make sex more of a cardio workout is to increase the time of the act.” C: The present study indicates that energy expenditure during sexual activity appears to be approximately 85 kcal or 3.6 kcal/min and seems to be performed at a moderate intensity in young healthy men and women. These results suggest that sexual activity may potentially be considered, at times, as a significant exercise. Moreover, both men and women reported that sexual activity was a highly enjoyable and more appreciated than the 30 min exercise session on the treadmill. Therefore, this study could have implications for the planning of intervention programs as part of a healthy lifestyle by health care professionals. B: We look forward to future studies that may further show the relationship between psychosocial/qualitative factors and energy expenditures which could explain how these variables could affect overall health and quality of life.____________________________Now we conclude episode 100, “Sexercise.” If you ever wondered if sexual intercourse was a good workout, today we learned that in general it is not an energy-demanding activity. The average man burns just 24 kilocalories during sex, but with some adjustments you can burn more calories, especially if the activity takes longer. If your patient is not having sex, they do not have to start having it just to exercise, remind everyone to be sexually responsible to prevent the spread of sexually transmitted infections and unintended pregnancies. Even without trying, every night you go to bed being a little wiser.Today we thank doctors Valerie Civelli, Namdeep Grewal, and Hector Arreaza. Thanks for listening to Rio Bravo qWeek Podcast.

Professor Chris Imray is a consultant vascular, renal transplant and trauma surgery at the University Hospitals Coventry & Warwickshire NHS Trust in Coventry, UK. He is also an Honorary Professor at Warwick Medical School, Coventry and Exeter Universities and immediate Past President of the Vascular Society of Great Britain and Ireland. Professor Imray has combined his love of mountaineering with clinical vascular surgery - he is involved in a number of polar medicine societies and is a world expert on the management of frostbite and non-freezing cold injuries. He has conducted research into hypoxia and ischemia at altitude and has published extensively. His personal accomplishments include a wide range of expeditions across the globe, from the sea cliffs of the Outer Hebrides in Scotland to the volcanoes of Chile and, most notably, to the summit of Everest.

In this episode, we explore the evidence on whether smaller endotracheal tubes are... 1. Less likely to maintain a secure patent airway 2. Less reliable in facilitating positive pressure ventilation 3. Less able to seal the trachea and protect the lungs from aspiration We also discuss the potential harms associated with larger endotracheal tubes.  Our guests are Dr. Shamir Karmali and Dr. Peter Rose from the Department of Anesthesiology at Vancouver General Hospital.

While generally thought to affect the elderly and the very young, it can affect people of all ages, not just because of the heat in the environment (classic heatstroke) but also because of activity (exertional heatstroke). The problems caused by heatstroke sometimes happen but don't appear clinically, like GI ischemia. Bitcoin is a decentralized cryptocurrency that's used in peer to peer transactions. This happened in 2011 when individual people could still mine coins, but now, miners are usually pools or in large facilities in places that have cheap electricity and cool climate to save on computer cooling costs.

We are honored to talk about sweet spot training with Dr. Andy Coggan, Ph.D on this podcast.  Dr. Coggan is an Associate Professor of Kinesiology at Indiana University's School of Health and Human Sciences.  IU has a doctoral program in Kinesiology so if there's a young cyclist out there that wants to study how to get faster, IU's Department of Kinesiology could be the place for you. 39701More Training For Your Limited Time Andy and Frank go way back to the early days of USA Cycling Coaches Education Program primarily from the power based training seminars and clinics.  In 2004 Andy presented at the Coaches Summit at USA Cycling's headquarter's in Colorado Springs, CO and introduced a power based impulse – response performance model. The term sweet spot training was born a few months later from a group of coaches working to validate the model which would later become the Performance Manager Chart in TrainingPeaks and WKO. Andy is also the co-author of “Training and Racing with a Powermeter” along with Hunter Allen. Of course we reference the sweet spot graph, address the arbitrary units from the y-axis and the expected physiological adaptations from training in Zones 1 – 7.

I denne episoden snakker vi med manuellterapeut og idrettsfysioterapeut Lars Haugvad om styrketrening. Paradoksalt er hans hobby og idrettsprestasjoner primært innen snowboard og jøgling, samt innen utholdenhetssegmentet med 2.47på maraton og 2.plass i Ironman. Allikevel slenger han oppdatert litteratur på bordet når vi diskuterer hvordan og hvorfor vi tester styrke og hvilken verdi ulik styrketrening har som tiltak i håndteringen av muskel- og skjelettplager. Vi går løs på noen myter både om styrketrening og coretrening, noe vi også skal høre mer om i fremtidige episoder. Lars er spesialist i idrettsfysioterapi og jobber på Olympiatoppen primært med landslagene i snowboard, beachvolley og seiling og har tidligere jobbet som medisinsk koordinator hopplandslaget. Han er også screeningansvarlig for de norske olympiske utøverne. Lars vil gjerne takke kolleger ved NIMI og Olympiatoppen for faglig utvikling, samt forskningsmiljøene ved Norges Idrettshøgskole, og rette ekstra takk til Gøran Paulsen som lar han surre rundt i fagmiljøet kraft/styrke.Referanser:Beyer, R. et al.

Imagine what it would have been like, to have lived in 1918. Spanish influenza killed approximately 3% of the world’s population. Other than the world war, international travel was fairly limited. There was no social media. No flu vaccine. No mechanical ventilators. No World Health Organization. A century later, we’re facing the next great pandemic. And what have we learned? What do we know? From the neurologic complications of SARS-CoV-2, to non-infectious consequences, the environmental impact of a pandemic, and lessons learned polio, we hope to leave you with a few important take-home messages, a silver lining—and some food for thought—about the ongoing COVID pandemic. ** IF YOU’RE TAKING YOUR NEUROLOGY BOARDS THIS SUMMER, CHECK OUT THE PENN NEUROLOGY BOARD REVIEW COURSE AT https://upenn.cloud-cme.com/default.aspx?P=5&EID=65373.

Low load BFR training and achilles tendon adaptations - an alternative to high load training

Happy New Year everyone. Today's podcast looks into low load BFR training and achilles tendons. This is quite an exciting paper due to the positive effects of Blood Flow Restriction training with tendon adaptation. Previously only high load strength training has shown positive responses to tendon so this is a great result for what BFR can bring to the user - i.e. we can finally use low load training to elicit a tendon response (with the addition of BFR). The other advantage of this session was how simple it was. There was a couple of points that I feel are quite important to note. Firstly, it was a 14-week training intervention. Typically a lot of academic studies are of 4-6weeks in lengths and probably this is why previous studies may not have shown positive training responses. The other point, was an incremental loading protocol - although the loads were still low (20-35% 1RM) every 4 weeks the load was increased by 5% and the subjects' max strength was reassessed and readjusted. This highlights that the body needs a continual increase in strength, even if we are using low-load BFR training. Therefore we can start to look at bringing this type of training to an "at-home" situation providing a simple solution for everyone. This same principle for other tendons (esp. shoulder and patella) I feel can also be applied. I've had great success with tendon issues acutely and this paper highlights that a longer (14 week) approach to tendon adaptation is needed. The article I review today is: Low-load blood flow restriction training induces similar morphological and mechanical Achilles tendon adaptations compared with high-load resistance training. Centner C1, Lauber B1,2, Seynnes OR3, Jerger S1, Sohnius T1, Gollhofer A1, König D1. J Appl Physiol 2019 Dec 1;127(6):1660-1667. doi: 10.1152/japplphysiol.00602.2019. Epub 2019 Nov 14. Abstract Low-load blood flow restriction (LL-BFR) training has gained increasing interest in the scientific community by demonstrating that increases in muscle mass and strength are comparable to conventional high-load (HL) resistance training. Although adaptations on the muscular level are well documented, there is little evidence on how LL-BFR training affects human myotendinous properties. Therefore, the aim of the present study was to investigate morphological and mechanical Achilles tendon adaptations after 14 wk of strength training. Fifty-five male volunteers (27.9 ± 5.1 yr) were randomly allocated into the following three groups: LL-BFR [20-35% of one-repetition maximum (1RM)], HL (70-85% 1RM), or a nonexercising control (CON) group. The LL-BFR and HL groups completed a resistance training program for 14 wk, and tendon morphology, mechanical as well as material properties, and muscle cross-sectional area (CSA) and isometric strength were assessed before and after the intervention. Both HL (+40.7%) and LL-BFR (+36.1%) training induced significant increases in tendon stiffness (P < 0.05) as well as tendon CSA (HL: +4.6%, LL-BFR: +7.8%, P < 0.001). These changes were comparable between groups without significant changes in Young's modulus. Furthermore, gastrocnemius medialis muscle CSA and plantar flexor strength significantly increased in both training groups (P < 0.05), whereas the CON group did not show significant changes in any of the evaluated parameters. In conclusion, the adaptive change in Achilles tendon properties following low-load resistance training with partial vascular occlusion appears comparable to that evoked by high-load resistance training.NEW &  Before you go and listen to the podcast could I ask a couple of favours: 1. If you know of someone who is suffering from achilles tendon issues please get them to listen to this podcast. 2. If you are enjoying the podcast please give it a positive rating on iTunes.   Thanks for listening.   In the methods, there was a couple of points around how Tendon properties was calculated and I mentioned that I would put it in the notes: How did they measure Tendon Stiffness? To assess tendon stiffness, elongation of the Achilles tendon was determined during ramped isometric contractions by B-mode US scans at 100 Hz at the gastrocnemius medialis myotendinous junction After familiarization with the procedure and preconditioning of the tendon with five trials at 80% of MVC, participants were instructed to steadily exert torque to their individual maximum with a standardized loading rate of 50 Nm/s. This loading rate was chosen because it resulted in a ramped isometric plantar-flexion contraction lasting between 3 and 5 s for all subjects. During this process, visual online feedback of the torque signal was provided. Achilles tendon force was calculated by dividing plantar flexion torque by the tendon moment arm with a subsequent correction for ankle joint rotation by kinematic data Tendon moment arm was calculated by measuring the perpendicular distance from the inferior tip of both medial (L1) and lateral (L2) malleolus (center of rotation) to the posterior part of the Achilles tendon. For this purpose pictures were taken from the medial and lateral sagittal planes (Sony Cyber-shot DSC-RX100 Digital Camera). In accordance with previous studies, the mean of these two measurements (L1,2) was used for further calculations. Subsequently, the intersection of L1 and L2 was indicated with a needle and the perpendicular distance (M) from the needle to the tendon’s line of action was measured (32). Tendon moment arm was then determined by subtracting M from L1,2 (for detailed descriptions see Refs. 32 and 50). All analyses were conducted with ImageJ (1.51; NIH). Tendon stiffness was then calculated as the slope of the force-elongation curve between 50% and 80% MVC. This procedure has previously been used in the scientific literature (56). Young’s modulus was calculated as the slope of the stress-strain curve between 50% and 80% MVC. What is Young’s Modulus? Young's modulus is a measure of the ability of a material to withstand changes in length when under lengthwise tension or compression. Sometimes referred to as the modulus of elasticity, Young's modulus is equal to the longitudinal stress divided by the strain.

Background: Inspiratory activity is a prerequisite for successful application of patient triggered ventilation such as proportional assist ventilation (PAV). It has recently been reported that surfactant instillation increases the activity of slowly adapting pulmonary stretch receptors (PSRs) followed by a shorter inspiratory time (Sindelar et al, J Appl Physiol, 2005 [Epub ahead of print]). Changes in lung mechanics, as observed in preterm infants with respiratory distress syndrome and after surfactant treatment, might therefore influence the inspiratory activity when applying PAV early after surfactant treatment. Objective: To investigate the regulation of breathing and ventilatory response in surfactant-depleted young cats during PAV and during continuous positive airway pressure ( CPAP) early after surfactant instillation in relation to phrenic nerve activity (PNA) and the activity of PSRs. Methods: Seven anesthetized, endotracheally intubated young cats were exposed to periods of CPAP and PAV with the same end-expiratory pressure (0.2 - 0.5 kPa) before and after lung lavage and after surfactant instillation. PAV was set to compensate for 75% of the lung elastic recoil. Results: Tidal volume and respiratory rate were higher with lower PaCO2 and higher PaO2 during PAV than during CPAP both before and after surfactant instillation ( p < 0.05; both conditions). As an indicator of breathing effort, esophageal deflection pressure and PNA were lower during PAV than during CPAP in both conditions ( p < 0.02). Peak PSR activity was higher and occurred earlier during PAV than during CPAP ( p < 0.01), and correlated linearly with PNA duration in all conditions studied ( p < 0.001). The inspiratory time decreased as tidal volume increased when CPAP was changed to PAV, with the highest correlation observed after surfactant instillation ( r = - 0.769). No apneic periods could be observed. Conclusion: PSR activity and the control of breathing are maintained during PAV in surfactant-depleted cats early after surfactant instillation, with a higher ventilatory response and a lower breathing effort than during CPAP.
