Official title
Exercise and Bone Development in Young Girls
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
