In this episode, Luc starts with an exploration of the roles of insulin and triglycerides in endurance exercise, highlighting their impact on skeletal muscle metabolism, and he offers profound insights into the significance of protein in this context. He elucidates how different protein types and forms influence muscle protein synthesis rates, exploring the nuances of protein absorption, digestibility, amino acid quality, and their implications for performance and recovery. Delving deeper, he differentiates between animal and plant protein sources, unraveling the distinctive properties of various protein types, from the differences between whey and 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, and dietary protein.
