Dietary Protein and Physical Training Effects on Body Composition and Performance

This chapter discusses the role protein and exercise play in the optimization of muscle mass and performance under normal conditions as well as during periods of acute and chronic muscle catabolism. Both the quality of protein and the quantity (dose) of protein can affect the rates of muscle protein synthesis (MPS) and muscle protein breakdown (MPB). While muscle mass is important, particularly in the context of aging, it is also important to …
