The purposes of this study are 1) to assess foot strike patterns initially, at six months and at one year between two groups of runners attempting to transition to a non-rearfoot strike pattern (NRFS) with and without the use of biofeedback technology, and 2) to prospectively compare injury incidence rates at one year between NRFS and rearfoot strike (RFS) runners.

| Change in Foot Strike Pattern From Baseline | Foot strike pattern will be either classified as rearfoot strike or non-rearfoot strike. This is determined by video analysis of 240hz camera. All participants baseline foot strike pattern was rearfoot at study enrollment. | Immediately post-training, 6mo post-training, and 1yr post-training |
| Measure | Description | Time Frame |
|---|---|---|
| Injury Incidence Between Foot Strike Patterns | Percentage of runners that became injured over 1 yr. Injury defined as pain in the lower extremity that caused restriction or stoppage of running for at least one week, or required the runner to consult a physician or other health care professional. | 1yr |
