Context: Baseball pitching requires the coordination of the lower and upper extremities to effectively generate and transfer force to the ball. High-velocity pitchers have been found to have significantly greater stride leg force generation than low-velocity pitchers. The influence of stride leg fatigue on pitching has yet to be investigated. Objective: The purpose of this study was to examine the effect of stride leg fatigue on peak vertical ground reaction forces (vGRFs) and hand velocity. Design: Pretest-posttest. Setting: Biomechanics laboratory. Patients or Other Participants: A convenience sample of 11 collegiate baseball pitchers (19.27 ± 0.64 years old; 85.88 ± 12.16 …
