Dr Glenn McConell chats with Professor Eddie Coyle from the University of Texas at Austin. Eddie has been instrumental in our understanding of the effects of carbohydrate ingestion and fluid ingestion during prolonged exercise and also physiological characteristics of endurance athletes (amongst other areas). Here we talk about his more recent very important and novel work. 
0:00 Introduction  
3:08. Inactivity and exercise resistance.
If do not undertake enough steps during the day (inactive) then exercise at night you will not increase your fat oxidation the next day. Standing no better than sitting in regards to this. What about if exercise twice a day or exercise hours a day? How fits with the fact that people with the lowest VO2 maxes have the biggest increases in VO2 max with exercise training? VO2 max adaptations compared with metabolic adaptations with exercise training in inactive vs active participants. Need to walk enough so that you don’t turn on the unhealthy responses to inactivity and then you need to exercise more vigorously to increase aerobic capacity and get those benefits as well. 
24:00. 4 second repeated sprints.
High forces without large increases in lactic acid production. Short rest periods so aerobic component. Remarkably get increases in VO2max, anaerobic capacity, strength and metabolic adaptations such as improvements in insulin sensitivity. Also neuromuscular adaptations. 18-30 x 4 sec sprints with 15-45 sec recovery (depending on stage and age). 10-20 min long training sessions. 50-70 yr olds respond similarly to younger participants and actually obtained thigh hypertrophy. People tolerate it well and receiving overwhelmingly positive feedback. Improved activities of daily life. 
48:00.  Efficiency in cyclists. 
Controversial question about whether he thought cyclists improve their efficiency with training.  
Inside Exercise brings to you the who's who of exercise metabolism, exercise physiology and exercise’s effects on health. With scientific rigor, these researchers discuss popular exercise topics while providing practical strategies for all.
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).
