Description
The purpose of this study was to examine changes in lower-body power from pre- to post-season in a women’s ice hockey team using broad jump (BJ) and countermovement jump (CMJ) assessments. Fifteen NCAA Division I athletes completed BJ and CMJ tests within a month prior to the competitive season and within a month following the final game. All tests were conducted at a consistent time of day and began with a standardized warmup, followed by the CMJ testing using dual force plates and BJ on a marked flat surface. CMJ metrics included in the analysis were jump height, relative peak and average propulsive power, and reactive strength index-modified (RSI-mod). Paired samples t-tests revealed significant (p < 0.05) increases in relative average propulsive power, RSI-mod, and broad jump distance. No significant changes in jump height or relative peak propulsive power were observed. These improvements suggest that the in-season strength and conditioning program effectively enhanced lower body explosiveness. Regular monitoring of power metrics can help guide training adjustments to optimize athletic performance and development throughout the competitive season.
