Luc van Loon is an internationally renowned expert in skeletal muscle metabolism. In this episode, Luc starts with an exploration of the roles of insulin & triglycerides in endurance exercise, highlighting their impact on skeletal muscle metabolism, & he offers profound insights into the significance of protein in this context. He elucidates how different protein types & forms influence muscle protein synthesis rates, exploring the nuances of protein absorption, digestibility, amino acid quality, & their implications for performance & recovery. Delving deeper, he differentiates between animal & plant protein sources, unraveling the distinctive properties of various protein types, from the differences between whey & casein to the emerging trends in collagen protein supplementation. Moreover, Luc dissects the intricate connections among physical activity, lean muscle mass, muscle protein synthesis induced by resistance training, & dietary protein.
