France16 participantsStarted 2025-09-01

Plain-language summary

The goal of this prospective interventional study is to measure the strength of the external and internal rotator muscles of both shoulders (dominant and non-dominant) of Montpellier Hérault Rugby players at different stages of their menstrual cycle. During the menstrual phase (beginning of the follicular phase from D0 to D5) and during the ovulatory/early luteal phase (approximately D13 to D18 of the menstrual cycle). The study is conducted on volunteers. The main question it aims to answer is : Is there an effect of the menstrual cycle on the maximum strength of the internal and external rotators of the shoulder in female athletes who play rugby?
