This project will evaluate the impact of resistance training on the synthesis and release of hormones and growth factors from the musculoskeletal system and the extent to which the communicative capacity influences glucose homeostasis In turn, the contribution of glucose regulation on the musculoskeletal system will also be evaluated. This small study will serve as a pilot/feasibility study to define a protocol for implementation of a resistance training intervention in the pediatric population. To establish feasibility, this study population is limited to overweight African American boys ages 7-11 years.
