简要总结
Adaptation to resistance exercise requires maximal rates of muscle protein synthesis, which can be achieved with post-exercise ingestion of ~20g of protein. These recommendations are based on studies in males and responses in females may vary.
Muscle recovery is related to the ability to build new muscle protein from amino acids (muscle protein synthesis). This response is thought to be impacted in females by hormones that fluctuate across different phases of the menstrual cycle. However, the effect of menstrual cycle phase on muscle protein synthesis is not known.
