Summary

This study looks at how natural menstrual cycles and birth control pills affect strength, hydration, and energy balance in 40 female athletes. Researchers will measure muscle strength, body water, and energy use at different times of the month. The goal is to better understand how hormones influence performance and health, which could lead to better training and nutrition advice for women.
