Senile osteoporosis. The effects of exercise.

The available literature indicates that a high level of physical activity throughout life can result in increased skeletal mass during the fourth decade. Such a large reservoir of bone mass at midlife may delay the clinical manifestations of osteoporosis in later life. Furthermore, the published studies of animal models and humans strongly suggest that physical activity retards or prevents involutional bone loss in both recently postmenopausal and very elderly women.
