Arthritis Pilot for Preserving Muscle While Losing Weight

The purpose of this research study is to see whether wearing a weighted vest during a period of active weight loss can decrease the loss of muscle and bone that occurs during weight loss. We will also determine if study participants who wear the weighted vest will have greater improvements in physical function and self-reported disability, pain, stiffness, fatigue and quality of life. This knowledge could impact weight loss programs designed for older adults. Hypothesis: Participants randomized to VEST will experience similar weight loss, but less loss of lean mass and bone density, than participants randomized to Control.
