Design outcomes
Primary
| Measure | Time frame |
|---|---|
| We will compare the change-of-direction performance and biomechanical variables before and after the 9-week intervention. Specifically, we will evaluate the completion time of the cutting maneuver along with knee flexion and dynamic valgus angles, trunk anterior/posterior lean, and lateral flexion angles. Furthermore, we will analyze the foot placement of the cutting leg relative to the body center of mass to determine the effects of the training and coaching on movement quality. | — |
