Study Description
Brief Summary:
This research study is looking to compare the effects of two uniquely different power training interventions (high force, lower velocity versus low force, high velocity) on changes in mobility status among older individuals at risk for mobility disability.

Condition or disease Intervention/treatment
Mobility Limitation Behavioral: Lower Extremity high velocity low force Power Training
