  Objective: To compare the mediolateral, anteroposterior and vertical ground reaction forces (GRF) of a drop jump landing (DJL) with eyes open and eyes closed conditions to analyze the effects of visual input on the body’s ability to modulate motion. Methods: An experimental crossover research design was used for this study. Twenty-four subjects were recruited to participate containing male and female subjects. All subjects performed a DJL from a height of 24-inches onto a force plate below for a total of 6 alternating attempts of 3 eyes closed and 3 eyes open. Maximal GRF were analyzed for each condition in the anteroposterior, vertical and mediolateral directions and averaged for each participant. Results: There was a statistical significance of the GRF analyzed when comparing the eyes closed with .. View More»
