摘要

Skeletal muscle is a dynamic tissue that is critical to the physical health and function of humans. The maintenance of muscle mass is largely dependent on the process of muscle protein synthesis (MPS), which is nutritionally regulated by the provision of amino acids in the form of dietary protein and can be augmented by prior contractile activity (e.g. exercise). However, not all proteins are created equally in their ability to enhance MPS. Contemporary research has revealed that to optimally stimulate MPS in young and old adults, similar to 0.25g/kg and similar to 0.4g/kg, respectively, of leucine-rich, rapidly digested protein should be consumed at rest and/or after exercise. The present review will briefly discuss current science that underpins these "muscle-centric" recommendations for dietary protein.
