Vigorous training, for example, can temporarily lengthen or even eliminate a runner's menstrual cycle. The response appears to have a healthy effect. In a separate study of ten rowers at Harvard, Frisch found that active women produce a less potent form of estrogen than their sedentary counterparts. Result: breast and uterine tumors that depend on the hormone cannot develop as easily. In addition, athletes lack excess body fat, which can predispose...
...Changes occur in the skin. The topmost layer, or epidermis, becomes dry and blemished. The middle layer, or dermis, thins dramatically, making the skin seem translucent, and becomes much less elastic and supportive.
