Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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?
