Summary

This study looked at whether the menstrual cycle changes shoulder muscle strength in high-level female rugby players. Sixteen players from Montpellier Hérault Rugby had their shoulder strength measured twice during their cycle: once at the start (days 0-5) and once around ovulation (days 13-18). The goal was to see if strength varies by cycle phase, which could help tailor training or injury prevention.
