Study Details

Brief 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.

Interventions and Outcome Measures

Arms

experimental: Run Retraining Conditions

Single-arm, within subject, repeated measures design. All participants will run at baseline and then under 3 different running 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.

Primary outcome measure

  • Ground Contact Time [ Time Frame: Within a single session, measured pre-intervention (baseline) and during each running condition intervention ]
