Which metric, glute med maximal voluntary isometric contraction (MVIC) activation during a stop hop test or stop hop distance, has a stronger relationship with knee valgus during an overhead squat. Explain what these data indicate (what kind of relationship?) Copy and paste a graph of this relationship.
Run a t-test and determine if 10-meter fly sprint speed is statistically different from the pre-season to the postseason (use the best time from the postseason). Also, calculate a coefficient of variation (CV) for postseason sprint times. Did the team adequately improve?
