Dans cet épisode, Jérémie et Simon discutent de 4 aspects qu'il considère soit surestimé (overrated) ou sous-estimé (underrated), et ils ne sont tous les deux pas d'accord sur chacun des points... Bien entendu, ils partageront leur point de vue et supporteront leur vision avec leur expérience et leurs connaissances scientifiques sur le sujet.

In this archive episode from 2020, Carolina Allen and Shelli Spotts discuss the origin and roots of the gift economy, and the way maternal feminism rests on an alternative structure, a way of living that does not depend on getting ahead but the responsibility to lift everyone up.  "We are born into a gift economy, one that starts with our own mothers. It is a far more natural way of living that does not depend on the economy of exchange, but on trust and generosity." Genevieve Vaughn Genevieve Vaughan was born in Texas in 1939. She is an independent researcher. After finishing college in Pennsylvania in 1963 she married philosopher and semiotician Ferruccio Rossi-Landi and moved with him to Italy where they had three daughters. The couple participated in the beginnings of the Semiotics movement in Italy as well as in the Italian Left, where Genevieve got her political consciousness raised. After her divorce in 1978 Vaughan became a feminist, participating in the Italian and international feminist movements. She began to see the fact of women's free labor in the home as a gift economy, the unacknowledged free economy of women from which communication and community derive. Her two early essays ‘Communication and exchange' (Semiotica 1980) and ‘Saussure and Vigotsky via Marx'(1981) deal with language and economics, a theme introduced by her husband but which she elaborated in alternative directions, and which she has been working on throughout the rest of her life. In 1983, Vaughan returned to Texas where she started the Foundation for a Compassionate Society, a multicultural all-women activist foundation which initiated many innovative projects for social change based on the political use of ‘women's gifting values'. The Foundation closed its doors in 2005 after two final international conferences: A Radically Different Worldview is Possible: The Gift Economy Inside and Outside Patriarchal Capitalism, 2004 and Societies of Peace: the Second Congress of Matriarchal Studies (under the guidance of Heide Goettner Abendroth), 2005. Several other conferences have been held including one in Toronto in 2011 called A (M)otherworld is Possible in collaboration with Goettner-Abendroth and in conjunction with the Association for Research on Mothering.   Carolina is the founder and leader of Big Ocean Women, the international maternal feminist organization representing perspectives of faith, family, and motherhood throughout civil society. Carolina holds a B.A. in philosophy from the University of Utah with an emphasis in cultural religions and philosophy of science. Her inspirational and philosophical work has been presented at various international U.N. conferences. She is a native of Brazil, and a fluent trilingual. She and her husband Kawika are parents to 7 children. She is an avid soccer fan and had a brief career as a semi-professional player. ShelliRae Spotts is an essayist, advocacy writer, screenwriter, and sometime poet who teaches creative writing and composition at Brigham Young University. She is passionate about exploring the ways we use stories to build bridges within our communities and her essays delve into the connections we discover through languaging our lived experiences. Shelli has attended the United Nations Commission on the Status of Women as an advocacy writer for the last several years, and is dedicated to social justice and environmental causes. She was the co-director and writing mentor for "Words for Water: Dancing the Stories of our Home Waters," a collaborative writing/dance advocacy project focusing attention on the challenges facing our rural river watersheds.  She is the author of a forthcoming essay collection, "Radical Creativity: On a New Economy of Care." When she is not teaching, writing, or reading, Shelli loves to spend time with her husband and four adult children watching great movies, attending live theatre, or dragging everyone outside to “look at the sky.”

V. M. Abstract: We studied the behavioral consequences of fentanyl vapor self-administration (SA) in mice with and without chronic neuropathic pain (one month after spared-nerve injury(SNI) model or sham injury). We assessed fentanyl consumption, motivation, and seeking during as well as anxiety, hyperactivity, immobility, and pain for two regimens of fentanyl SA: 1) Dose escalation, where over a 3-week period mice are exposed (daily 2-hour sessions) to escalating numbers of fentanyl puffs per active nosepoke (from 1 puff/active nosepoke for first 3 days, up to 6 puffs/active nosepoke in days 16-18). 2) Effort escalation, where over a 3-week period (daily 2-hour sessions) mice need to increase effort to acquire the same amount of fentanyl (fixed ratio 1 (FR) = 1 active nosepoke results in 1 fentanyl puff, while second and third week we use FR5 and FR10). We observe sex-, injury- and regimen- dependent differences in outcomes. Importantly the dose escalation regimen resulted in higher seeking behavior (post forced abstinence, context and cue driven nosepoking in the absence of fentanyl delivery), long lasting increased anxiety, immobility, and hyperactivity, as well as transient but full pain relief in SNI mice. Therefore, this regimen seems a better rodent model for translating outcomes to human chronic pain patients managed with opioids. Copy rights belong to original authors.

EMG studies, they're the classic “evidence-based” tool to “Um actually” all the bros about what the perfect exercises they should have chosen for every muscle group. Or are they? Today we're joined by returning guest, Ph.D. candidate Andrew Vigotsky, who's published some of the most influential papers on the limitations and the best practice guidance for EMG research. In this episode, we learn what EMG data can and can't tell us, what types of evidence we should rely on to inform exercise selection, and what research we should perform in the future to move the field forward. Ultimately, we unfortunately learn that the good old days of T-Nation articles might be sadly behind us.

Biomechanics is the understanding of the body’s structure, function, and motion with physics to describe what we experience. As lifters, most of what biomechanics explains mathematically, we understand intuitively. But, in a complex dynamic system like the human body, sometimes what we experience, or our assumptions based on a limited understanding of biomechanics, can be counterintuitive and misleading. To clear up the confusion and address the popular tropes, we’re joined by Megan Bryanton-Jones, PhD, the powerlifting biomechanist behind Kinetic Advantage. She joins us alongside returning guest, the PhD candidate and intellectual entity known as Andrew Vigotsky, on this episode of Iron Culture.

Or is the squat a decent exercise to develop the quads and glutes until it’s not?What is the muscular limiter for the barbell squat? Is it even a muscle?Episode 20 Notes “From these data, it is unclear if strengthening a single muscle group (e.g., knee extensors) would increase squat strength, as the strength of one muscle group does not appear to relate more strongly to squat strength than another…Net joint moments observed during the squat do not approach 100% of what each joint can produce in isolation…The relationship between individual joint strength and multi-joint strength may be highly nonlinear and paradoxical, owing to the increased degrees of freedom of multi-joint movements…Humans may be less than the sum of their parts when it comes to multijoint force production”Vigotsky et al. 2018It seems like counter to what people think that by putting the barbell further away from the center of mass you are probably allowing for a more upright torso…until you aren’t. Meaning we actually see more and more erector spinae activity as you move the bar further out so the likely limiter here is just your ability to hold the position under increased fatigue and loading. https://journals.lww.com/nsca-jscr/Fu... and we probably can’t trust our eyes here for telling when people lose lumbar “neutrality” anyways.https://www.ncbi.nlm.nih.gov/pubmed/2...The glutes aren’t really working much in the bottom of the squat (the hardest part of the lift) in their lengthened position…it looks like that is primarily adductor magnus. So the glutes really wouldn’t be the limiter to extend the hip ever in the squat and wouldn’t even be used much until after 90 degrees and their force output above 90 is likely way more than anything we could put on the bar anyways. https://www.ncbi.nlm.nih.gov/pubmed/3...https://www.ncbi.nlm.nih.gov/pmc/arti...https://www.ncbi.nlm.nih.gov/pmc/arti...https://www.researchgate.net/publicat...https://www.ncbi.nlm.nih.gov/pubmed/2...Could the muscular limiter in a barbell squat variant ever really be the quads?We generally see people tip forward as they start to fatigue out later in a set.

En attendant le prochain épisode d'analyse d'album, je vous propose un nouveau format qui me trottait dans la tête depuis très longtemps : le talk. L'idée est d'aborder des thématiques liées à la musique sur un point de vue plus général qui peut aller de la simple pensée à la philo ou, ici, la sociologie. Le point de départ de cet épisode est lié à la lecture du livre "La Vie Est Plus Belle En Musique" de la pianiste Anne-Claire Le Guay. Elle y parle de son parcours et une phrase m'a fait réfléchir sur le choix de l'instrument quand on est enfant. Est-ce qu'on choisit vraiment son instrument, comme elle le sous-entend, ou ce choix est-il déterminé par nos origines sociales?  J'essaie d'y apporter ma réponse qui n'est pas une vérité absolue bien entendu.  Si le sujet vous intéresse, n'hésitez pas à vous renseigner sur les notions de déterminisme social avec notamment les écrits de Pierre Bourdieu (et la notion d'habitus) et celle de socio-constructivisme avec les recherches de Vigotsky.

On this episode of the Healthy Wealthy and Smart Podcast, I welcome Andrew Vigotsky and Dr. Nick Rolnick back on to the show to discuss Andrew’s paper, Interpreting single amplitude in sports and rehab sciences.  In this episode, we discuss: -What information can you conclude from a surface EMG study -The limitations of surface EMG research -What to look for in a surface EMG methods section -And so much more!   “I would urge practitioners not to make clinical decisions primarily based off of surface EMG or any acute type of measure especially when they want a longitudinal outcome for a given patient.”   “There are no studies that validate surface EMG as a predictive outcome for strength or hypertrophy.”   “Look for studies that are relevant to your patient population and your outcomes.”   “I would look at all surface EMG studies with a critical eye especially as they pertain to your patient population and desired patient outcomes.”   “Don’t apply measures that aren’t validated to the outcomes you want.”   For more information on Andrew: Andrew is currently a PhD student in Biomedical Engineering at Northwestern University, where he studies neuromuscular biomechanics. He has published papers in areas ranging from rehabilitation to surface electromyography methodology and biomechanical modeling. His dissertation works aims to understand the neuromechanical implications of muscular heterogeneities.   For more information on Nick:  Dr. Nicholas Rolnick, DPT is a licensed physical therapist, the founder of the Human Performance Mechanic and the co-founder of Blood Flow Restriction Pros. He received his Doctor of Physical Therapy Degree with academic honors from Columbia University in New York City. Through his work as a physical therapist his goal is to keep his patients in perfect balance, have the skills to recognize asymmetries and help patients enjoy the benefits of pain-free movement. He teaches across the United States as a clinical instructor for SmartTools Plus and is an adjunct faculty member at Concordia University – Chicago where he teaches Kinesiology I and II in their MS Applied Exercise Science Program. He also speaks nationally and internationally on the use of blood flow restriction therapy for various diagnoses and populations. He has been featured on The Mind Muscle Project Podcast, Highly Functional Podcast, The Muscle Medicine Podcast, The Missing Variable Podcast, the PTA Tapes Podcast and the Alinea Podcast. He currently lives and works in New York City.   Resources discussed on this show: Vigotsky, Andrew & Halperin, Israel & Lehman, Gregory & Trajano, Gabriel & Vieira, Taian. (2018).

On today’s episode of the Healthy Wealthy and Smart Podcast, Andrew Vigotsky joins me to answer audience questions and translate biomechanics literature to clinical practice. Andrew is currently a Master's student in Biomedical Engineering at Northwestern University in Evanston, IL, concentrating on musculoskeletal biomechanics. His thesis work aims to elucidate the relationship between the shear-wave velocity of muscle, as measured using Supersonic Shear Imaging, and muscle stiffness in vivo. In this episode, Andrew answers: -What is your biggest surprise on engaging clinical practitioners with research evidence? -How much do you feel biomechanics matter when looking at injury and pain development across various exercises? -If you were building your own program to maximize muscle hypertrophy what parameters would you use? -What can we draw from EMG studies and what conclusions are fair to make? -And so many more!   The goal of biomechanics research is to ultimately translate results to the clinic and enhance how clinicians treat their patients. Andrew states, “It’s only after you find those answers that you really understand what your results mean and how your question can affect society.”   Despite the large amount of research done each year in university labs, very little reaches practioners. Andrew notes, “There is a time lag from research to practice in the medical field of about 17 years.” Andrew believes clinicians can improve this transmission rate through a greater focus on science literacy and improved dissemination of new findings.   Best evidence based practice encompasses all elements of a biopsychosocial framework. Andrew believes, “Biomechanics still matters… It’s just in what context does it matter. From the people that are purely biomechanical, the neurophysiological and the pain science stuff matters a lot and we can’t ignore that.”   For more information on Andrew: Andrew is currently a Master's student in Biomedical Engineering at Northwestern University in Evanston, IL, where he is concentrating on musculoskeletal biomechanics. His thesis work aims to elucidate the relationship between the shear-wave velocity of muscle, as measured using Supersonic Shear Imaging, and muscle stiffness in vivo. He is completing this work in two different labs: the Neuromuscular Biomechanics Laboratory and the Neurobionics Lab, under Drs. Sabrina Lee and Elliott Rouse, respectively. Before attending Northwestern, Andrew graduated with a BS in Kinesiology from Arizona State University (ASU). It was during those undergraduate studies that he started getting involved in research; Erin Feser supervised him in ASU's Motion Analysis Laboratory, where he carried out two data collections that resulted in three publications. The studies investigated the effects of load on good morning kinematics and EMG amplitude, the acute effects of anterior thigh foam rolling, and the validity of the modified Thomas test. In addition to Erin's mentorship, I also grew close to Dr. Rick Hinrichs, who taught me a lot about biomechanics both inside and outside of the classroom.  While at ASU, Andrew was also able to secure an internship under Dr. Bret Contreras while he was completing research for his Ph.D. Bret has had a profound impact on how he thinks about movement and sports science. Together, they have published over a dozen papers related to strength, muscle hypertrophy, and physical performance, and have much more in the pipeline. Moreover, he has introduced Andrew to other great minds and researchers, such as Chris Beardsley and Dr. Brad Schoenfeld. After graduating from ASU, Andrew completed pre-requisites for graduate school (i.e., math, physics, and engineering courses) at a local community college while splitting time between two laboratories: the Leon Root, MD Motion Analysis Laboratory, at the Hospital for Special Surgery (HSS), and the Human Performance Laboratory, at CUNY Lehman. At HSS, he worked under Dr. Andrew Kraszewski to develop a 3D-mesh model of the gluteus maximus. At CUNY Lehman, he worked under Dr. Brad Schoenfeld to train participants and collect data for a training study, and also designed and carried out a cross-sectional study that investigated the determinants of squat strength, which is currently in peer-review.   If you are interested in learning more about what Andrew has done or reading works that he has published, you can check out it out at ResearchGate, Google Scholar, PubMed, or my CV.   Resources discussed on this show: Andrew Vigotsky Twitter Movement Science Blog   Thanks for listening and subscribing to the podcast!
