Summary

This study looks at how natural menstrual cycles and oral contraceptive use affect muscle protein synthesis after resistance training. Twenty recreationally active women will consume protein drinks and undergo muscle biopsies to measure protein building. The goal is to understand if hormone fluctuations change how muscles respond to exercise and protein, which could lead to better fitness advice for women.
