Abstract

The purpose of this study was to identify regions of an overground sprint trial required to accurately determine independent Horizontal Force Velocity (FV) measures. Forty-seven university aged athletes completed two separate overground sprint trials. Baseline FV metrics; theoretical maximum velocity [V_0], peak velocity [V_max], maximum power [P_max], maximum theoretical force [F_0], decrease ratio of force [DRF], and force-velocity slope [〖FV〗_slope] were calculated for each trial. Trials were then modified by systematically removing percentages of the total sprint from the beginning and end of the trial independently. FV metrics were compared at each percentage stage and compared to baseline. Results of this analysis indicate that no changes occur in FV variables until 7% of the sprint is removed from the end of the sprint, while significant changes are present after any alteration of data during sprint onset.
