Genetic Link to Sleep and the Negatives of Sleeping Too Much

Dr Glenn McConell chats with Professor Shona Halson from the Australian Catholic University, Melbourne, Australia. We chatted about how much sleep athletes need compared with how much sleep they actually get. Night sleep vs naps vs total sleep in athletes vs non athletes. The importance of consistency of sleep. Caffeine, sleep and exercise performance. Is overtraining actually a lot less common than believed? Ice baths may reduce hypertrophy with resistance training but improve team sports/endurance. Effects of compression garments on recovery. The effects of mental fatigue on exercise performance. A very interesting chat. Twitter: @ShonaHalson

The interviewer, Emeritus Professor Glenn McConell, has an international research profile following 30 years of Exercise Metabolism research experience while at The University of Melbourne, Ball State University, Monash University, the University of Copenhagen and Victoria University.
He has published over 120 peer reviewed journal articles and recently edited an Exercise Metabolism eBook written by world experts on 17 different topics (https://link.springer.com/book/10.1007/978-3-030-94305-9).
