This study aimed to investigate the method of evaluating the ability of power exertion at the lower limb for female collegiate athletes. A total of 103 female collegiate athletes belonging to the athletic club performed vertical and squat jumps (VJ and SJ, respectively) on the laboratory floor. The vertical ground reaction forces of both legs were determined by using a force platform (500 Hz) for calculating these jumping heights. The increase ratio of the jumping height (%) was calculated as ((height of VJ - height of SJ) / height of SJ) × 100. Significant positive relationships were observed between the heights of VJ and SJ (r=0.836, p<0.001), and the increase ratio of jumping height (r=0.249, p<0.05). Based on each average of the height of SJ and the increase ratio of jumping height, the athletic clubs (9 groups) were divided into the Excellent, Power, Technique, and Poor types. Athletic clubs that have superior athletic performance had a greater height of VJ, and are classified in the Excellent type. This study method could be useful to evaluate the ability of power exertion at the lower limb of athletic clubs.
