Examining the Most Effective Method to Reduce Running Ground Contact Time
Sponsor: Keller Army Community Hospital
Summary
The purpose of our study is to establish the most effective running retraining technique to decrease ground contact time. This will be investigated by applying three running retraining conditions and assessing the change in ground contact time and other biomechanical variables between the runner's baseline running and each retraining technique.

Conditions
Interventions
Real-time Visual Feedback
Runners will visualize their real-time ground contact time (GCT) measured by the RunScribe on a TV screen. They will be instructed to run with a goal of matching their target GCT. Their target GCT will be 5% less than their baseline.
Real-time Auditory Feedback
Runners will be instructed to match their step rate to a target step rate, 10% above their baseline step rate. A metronome will be played over a speaker to provide real-time auditory feedback of the target step rate.
Real-time Verbal Feedback
The clinician will provide real-time verbal feedback to runner to "pull your foot off the ground as quickly as you can," every 15 seconds during the retraining condition.
