History of Changes
  Purpose

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 Intervention
Mobility Limitation
 Behavioral: Lower Extremity high velocity low force Power Training

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Treatment
Official Title: Lower Extremity Muscle and Function in the Elderly: Study 2

Further study details as provided by Tufts University:

Primary Outcome Measures:
  • Peak lower extremity velocity [ Time Frame: Change from Baseline to Week 4, change from baseline to Week 16 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
