S3 EPISODE 22 - Athlete Asymmetry & Impacts on Performance and Return To Play w/ Chris Bishop MS

Season 3, Episode 22

Dr. Bubbs interviews Chris Bishop MS, Senior Lecturer in Strength and Conditioning at the London Sport Institute and current Chairman of the Board of Directors for the UK Strength and Conditioning Association. In this episode, Chris discusses his research in inter-limb asymmetries or differences in strength and power in athletes. He shares current assessment methods to detect asymmetries and how they impact performance in athletes. Chris also talks about the various methods that can be used to correct or limit asymmetries in athletes, as well as whether a ‘threshold’ exists for asymmetries, and when practitioners should address an asymmetry in athletes. Finally, he shares his thoughts on return to play and the evolution of research in athlete asymmetries.

Summary of This Episode

5:00 – Chris’ background

10:00 – Definition of asymmetries in performance

14:00 – Assessment methods for asymmetries

17:00 – How do asymmetries impact performance in athletes?

28:30 – What methods can be used to correct or limit asymmetries in athletes?

32:30 – When do you really need to address asymmetry in athletes?

40:00 – Return to play - how do asymmetries impact injured athletes?

S3E21: Effects of Protein Supplementation on Strength and Fat-Free Mass w Dr. Rob Morton PhD(c)

Season 3, Episode 21

Dr. Bubbs interviews Rob Morton, PhD Candidate in the Protein Metabolism Research Laboratory under the mentorship of Dr. Stuart Phillips at McMaster University. In this episode, Rob talks about his research into the effects of protein supplementation on strength and fat-free mass. He’ll highlight just how much of a benefit (or not) protein supplementation has when combined with strength training, if athletes need more protein than recreational trainees, and how much protein type really matters. Rob also discusses the impact of protein supplementation on fat-free mass, if there is an upper threshold for muscle protein synthesis, and what happens to protein excess in the body. Finally, Rob shares key insights on how protein requirements change as you age, effects on kidney health, and the evolution of research in this area.

Summary of This Episode

5:00 – Rob’s background

10:30 – Benefits of added protein supplementation for athletes

12:00 – How much does training impact your gains vs. protein supplementation?

13:00 – Protein types – Does it even matter?

14:30 – What is the proposed upper threshold for muscle protein synthesis?

17:00 – How is excessive protein intake utilized in the body?

19:00 - Is 1g per pound bodyweight still a good heuristic?

22:30 -  How to achieve higher doses of protein as we age?

30:30 -  Protein intake and kidney health

36:00 – General heuristics on protein and health

40:00 – The evolution of research on protein and health

About Dr. Rob Morton PhD

Robert Morton is a PhD Candidate in the Protein Metabolism Research Laboratory under the mentorship of Dr. Stuart Phillips at McMaster University. Rob’s passion is understanding how exercise and nutrition mediate skeletal muscle size, and why there is individual variability. Rob combines his background in Strength and Conditioning with his academic training to provide a practical and evidence-based appraisal of current dogma in sport science. Indeed, Rob’s research has been published in leading sport science journals and has been featured in a number of media outlets including The New York Times, The Globe and Mail, Global News, Men’s Health and Sports Illustrated.

S3E8: Muscle Loss, Sarcopenia, and Implications for Healthy Ageing w/ Dr. Theo Ispoglou PhD

Dr. Bubbs interviews Dr. Dan Cleather PhD to discuss all things strength and conditioning. In this episode, Dan outlines the most common mistakes trainers, clients and athletes make in training, the problem with conventional guidelines for training intensity, and the value of starting a program small. He’ll also share his preference for wave loading, the value of autoregulation, why it’s important to leave sessions feeling better than when you started, his MOST important “cardinal rule” of training, as well as insights from years working in the trenches. This episode is loaded with evidence-based insights and wisdom from Dr. Cleather!
