Pedometer-recorded physical activity of 34 menstruating women showed three peaks during the menstrual cycle—one at each end and one in midcycle. The latter, coinciding with the time of ovulation, suggests that women have the same type of estrus-induced motor activity characteristic of many other mammals. The two end peaks support the viewpoint that ovulation is not essential to the production of such augmented activity.
