Relationship between the menstrual cycle phases and wellness on football performance in sub-elite players

The effect of hormonal fluctuations of the menstrual cycle on performance remains understudied. [...]this study aims to explore the relationship between the menstrual cycle phases and wellness on football performance. Player kinematic and load performance was assessed via Global Positioning Systems (GPS) devices during each training session and match. Weekly external loads over the season averaged: total distance 15,871 (9206)m, percent maximal speed 89 (17.2), high speed running distance 1636 (1048)m and high metabolic load distance 2222 (1323) m. Discussion: Variations in perceived menstrual cycle effects on performance and training were observed between players.
