Abstract

The purpose of this study was to compare the false step (FS) to the straight out step (SOS) out of a parallel athletic stance (PAS) in Division I college athletes. 30 Division I college athletes from football, baseball, softball, and volleyball performed three repetitions each of the FS and SOS. Each trial was timed at 5 and 10 yards using the TC Brower Timing System as well filmed from two vantage points for kinematic data collection using the Ariel Performance Analysis System (APAS). From this, the velocity of the center of mass (VCM), projection angle of the center of mass (PCM), and acceleration (A) was calculated. Results showed greater VCM and A for the FS compared to the SOS. The PCM was in the upwards direction for the FS, while the PCM for the SOS was downward. The results from this study suggest that the FS is superior in terms of increasing the velocity of the center of mass and acceleration, while projecting the center of mass in a direction that allows for better velocity and acceleration.
