The protective role of estrogens against muscle microdamage is supported by findings from some studies; however, it is questioned by others. The aim of the present study was to investigate the effect of eccentric exercise on biomarkers of muscle microdamage and on oxygen uptake during two phases of the menstrual cycle in healthy premenopausal women.
