Examining the Most Effective Method to Reduce Running Ground Contact Time

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.

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.

"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."
