High Intensity Strength Training & Bone Mineral Density in Young Women

The current guidelines emphasize the prevention of bone loss, by building up bone mass in young age, as one of the most important measures to reduce the incidence of osteoporosis. Strength training and "explosive" exercises have been shown to have beneficial effects on bone mass and bone metabolism in both young and postmenopausal women. However, meta-analysis concludes that it is still unclear what type of exercises, intensity and execution that is most effective for skeletal adaptations. The following study will examine the effect of 12 weeks of heavy, explosive strength training on bone mineral density and bone metabolism in young, healthy girls aged 18-30 years.
