Abstract :The aim of this study was to explore the impact of the menstrual phases on exercise capacity parameters measured by a treadmill exercise test in sedentary premenaupausal women. Exercise capacity expressed in terms of metabolic equivalents insert ignore into journalissuearticles values(MET); and exercise duration was measured by performing treadmill exercise tests in 30 women insert ignore into journalissuearticles values(mean age: 29 ± 5.8 years); with regular menstrual cycles at two points during their menstrual cycles: the late-follicular insert ignore into journalissuearticles values(LF); phase and the mid-luteal insert ignore into journalissuearticles values(ML); phase. The exercise duration was significantly higher insert ignore into journalissuearticles values(P < 0.05);, and the exercise capacity insert ignore into journalissuearticles values(in MET); tended to be higher insert ignore into journalissuearticles values(P = 0.075); in the ML phase than in the LF phase. These results suggested that the menstrual phases in sedentary women can have an influence on exercise capacity. These changes may be attributed to the relative changes in the female steroid hormones between the LF and the ML phases.
