Effects of Stimulus Timing on the Kinetics of a Directed Jump Landing, The
Introduction: Tearing the anterior cruciate ligament (ACL) is a significant threat to athletes when an unanticipated component is present. The current research investigated the change in injury and performance kinetics when manipulating the timing of a directional stimulus through a range of 0ms to 400ms before landing. Methods: Thirteen uninjured recreational athletes jumped forward from a 30cm tall block, landing bilaterally with the dominant foot on a Bertec forceplate. Upon landing, participants either performed a vertical jump or a left/right jump at 90°, indicated by an LED panel. Stimuli ...
