Brief Summary

The fluctuating concentrations of female sex hormones, namely estrogen and progesterone may have an effect on the ability of the tissue to withstand challenging exercise conditions, such as eccentric exercise. These sex hormones have also been purported to influence the perceived difficulty of exercise. This study aims to uncover how the different estrogen and progesterone concentrations present throughout the menstrual cycle effect perceived readiness to perform, perceptions of difficulty, and different recovery metrics.
