Summary

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.

Conditions

Interventions

BEHAVIORAL

Heavy, explosive strength training

All participants of the training group will pursue a 12 weeks of heavy, explosive strength training, 3 sessions a week for a total of 36 sessions. The training session will include one squat exercise only, which allows muscle contraction of the quadriceps from a 90° bend at the knees to straight legs.

BEHAVIORAL

recommendations

The control group will be encouraged to follow a training program according to recommended exercise guidelines: * Weight bearing activities (walking, jogging or strength training) * 30 - 60 minutes, 3 - 5 times each week * A total of 2 - 3 hours each week should be achieved
