Shiloah Kviatkovsky, PhD CISSNCollagen - the secret ingredient to joint health?Dr. Kviatkovsky's talk reviewed the subject of collagen and joint health. I found it interesting that sex differences exist in levels of joint pain. Granted, this work was applicable to athletes, non-athletes, and even older adults, where pain can be an important issue. Essential aspects are if athletes need to address joint pain, both steroids and Non-Steroidal Anti-inflammatory Drugs (NSAIDs) can also cause problems with training or biomarkers associated with performance. Collagen is sometimes overlooked as an essential supplement in an athlete's diet, and this talk highlighted how collagen could be the answer to address problems with joint health – as a study of collagen protein use over six months shows improvements in knee-related functions and decreases in pain, indicating potential benefits for joint health and quality of life. 

Speaker: Eric Trexler, PhDTitle of Talk: Fueling the energy cost of exercise; Is there an "exercise energy compensation?" Dr Trexler's presentation explored the interesting relationship between exercise and energy expenditure, touching on a potential "exercise energy compensation" mechanism. His research focused on the various components of daily energy expenditure, including basal metabolic rate (BMR), non-exercise activity thermogenesis (NEAT), thermic effect of food (TEF), and exercise activity thermogenesis (EAT). The talk also discussed how these elements contribute to overall energy balance and how exercise influences energy utilization. Data was presented on total energy expenditure related to age, sex, and fat-free mass, offering insights into how these variables interact. Furthermore, different models of energy expenditure were compared, such as additive versus constrained models, highlighting the body's complex responses to physical activity. I found it also interesting that metabolic pathways were also examined, illustrating how the body processes different macronutrients and the resultant energy yield. He also introduced the "Dual-Intervention Point Model", suggesting a regulatory mechanism within the body that responds to changes in body weight or fatness due to environmental pressures and physiological controls. The model also proposes that the body has set points for intervention, which could be crucial in understanding weight management in the context of physical activity and exercise.

Join our fun conversation with Dr. Jorn Trommelan as we smash the myth of the 20-gram protein limit.   Don't miss this protein-packed episode that will leave you rethinking everything you thought you knew about the role of dietary protein in your body.Episode 62 Timeline: 2:29 How did Dr. Trommelen come up with the (milk) protein dosing for the 100-gram study?  Milk has the largest contribution to protein intake in the Western world.3:22 Prior dose-response studies – well accepted that 20 g of protein is all you need in a single meal; anything else above that is oxidized.4:05 This new study question was inspired by the copious consumption of BBQ meat!5:09 Do we need to distribute protein throughout the day?6:18 Snakes can eat >20% of their body mass in a single meal7:05 Why the 0, 25, and 100 gram dose? This study is absurdly expensive! So for all the fake science peeps online that have never done a study, STFU.8:20  25 gram dose was used as is the “upper limit” based on prior data; 100 grams for the simple reason that it is likely the upper limit of what a large male could likely eat in a single meal.9:33 The exercise protocol was a basic whole-body resistance training regimen10:37 Total protein intake vs. timing/distribution13:00 What would you speculate on 100 grams of protein twice a day versus 50 grams of protein four times a day?17:50 Your protein requirements are likely based on lean body mass? Perhaps…not much data.21:00 What is the upper limit?  There is a practical upper limit in terms of how much you can consume.22:25 What happens when professional eaters consume 80 plus hot dogs?26:25 Protein intake in talented Dutch athletes – they seem to under-report protein intake by 25%27:39 Dr. Trommelen is skeptical of the protein intake in the high-protein studies done by Jose Antonio. Are they over-reporting their intake?29:00 Male bodybuilders are the group that does not over-report protein intake.32:10 Compare acute feeding data vs what humans do in real-life (i.e., humans eat mixed meals throughout the day).33:27 Most long-term studies are not “long-term.”33:47 Most people over-estimate the role of protein vis a vis muscle growth.37:40 Plant vs Animal based protein – the total anabolic response is lower? 39:15 The issue with veganism is they eat less protein in general and the quality is lower.43:27 What would happen if an endurance athlete chronically did pre-sleep protein?45:22 Jorn gives thoughts on the 1.6 g/kg of protein daily as a “starting point” with the flexibility to elevate it as needed. Carbs and fats as needed.50:39 Good to see higher protein recs for endurance athletes.50:59 Endurance athletes are already probably at 1.5 g/kg/d. Why do folks recommend lower? It’s so silly.About our guest:Jorn Trommelen PhD works as an Assistant Professor at the Department of Human Biology. He is involved in research and education regarding the impact of exercise and nutrition on muscle mass and function. His research is part of the M3 research group and focuses on exercise and nutritional interventions to augment exercise performance and training adaptations in athletes.About the ShowWe cover all things related to sports science, nutrition, and performance.
