Exercise and Bone Development in Young Girls
In Brief
A clinical study evaluating Skeletal loading for Adolescent Development. Completed, enrolled 509 participants across 1 site.
Detailed Summary
The Jump-In study will prospectively assess the effects of impact exercise on skeletal development in young girls, including bone mass, bone mineral density, and bone geometry. We hypothesize that girls who regularly participate in impact loading exercise will accrue greater skeletal mass, increase bone density and undergo structural adaptations that in combination will improve bone strength compared to girls who do not participate in impact exercise.

Timeline
Interventions
Impact activities, 3 times per week, increasing the number of jumps (up to 40) and increasing height (from 6 inches to 24 inches per repetition) over the initial 8-weeks (2 months). New activities will be introduced approximately every 2-3 months in order to continually stress the skeleton over 2 years.
