Proper tuck jump technique. The athlete begins in deep hip and knee flexion, and should swing the arms backward in preparation for the jump. The goal is to minimize frontal plane motion of the trunk and lower extremities, while achieving thigh position that is parallel to the floor at the height of the jump. The sports medicine clinician should view the athlete during repeated jumps in both the sagittal and frontal plane views in order to identify take-off and landing asymmetries.
