Efficacy of Plyometrics to Increase Bone Mass in Male Cyclists With Osteopenia - Full Text View

Purpose

This study will compare the ability of two types of long term (12 months) weight-bearing exercise treatments (1. high-intensity jumping and 2. weight lifting) to increase the level biochemical mediators of bone formation and reduce those of bone breakdown in male cyclists exhibiting lower than normal bone density of the spine and/or hip. Additionally, will we compare the ability of both exercise treatments to improve the accrual of bone minerals (bone mineral content) and subsequently bone strength via bone mineral density.
