[Influences of resistance training on bone.]

Resistance training has been known to be effective to maintain and improve bone mineral density(BMD)and bone strength. Resistance training in combination with other types of exercise might be effective for maintaining BMD in patients with osteoporosis. Resistance training improves a decrease in BMD through an enhancement of bone formation and a suppression of bone resorption. It is thought that resistance training might affect bone metabolism through direct biomechanical force on bone cells and endocrinological factors as well as the nervous system.
