Effect of a Secondary Cognitive Task on Lower Extremity Biomechanics during Landing, The
Background: The purpose of this study was to examine the effect of a cognitive task on jump-landing biomechanics and performance. Methods: 31 recreational athletes participated in the study. Participants jumped forward off of a 30cm box a distance equal to one half of their body height, then immediately performed a countermovement jump. This movement was performed in a control condition, while counting backwards by intervals of 1, and by intervals of 7. Initial knee flexion, knee range of motion, peak vertical ground reaction force (PVGRF), stance time, and jump height were calculated. Results: ...
