eF, Early follicular; F, Follicular; HR, Heart Rate; mF, Mid follicular; mL, Mid luteal; L, Luteal; lF, Late follicular; N, No statistical difference between the phases; Y, yes, there was a statistical difference between the menstrual cycle phases. Upward arrow indicates which menstrual cycle phase had greater endurance time (i.e., less fatigability). yr, years old.
