The purpose of this study was to evaluate changes in muscle power performance in a horizontal (forward movement), vertical, and lateral directions in collegiate basketball players due to the presence of an in-season resistance training program (ISRTP). Four basketball teams were recruited for this study. Two women's basketball teams and two men's basketball teams participated with one team in each gender participating in an ISRTP and one team not participating in an ISRTP. Fifty-three collegiate basketball players (Females= 29, Males= 24) were successfully recruited for this project. Subjects were assessed for lower extremity muscle power and muscle strength at pre-season, mid-season and post-season in order to evaluate any changes that occur over the course of a collegiate varsity basketball season. Margaria-Kalaman, single leg horizontal leap, single leg vertical leap, single leg lateral leap, 5-10-5 shuttle run, estimated RM leg press performance data were collected. Statistical analysis was performed with a multivariate analysis of variance with repeated measures. Results show that an in-season resistance training program significantly impacted the changes over the course of the season (p< .001) as well as a significant interaction with ISRTP and gender (p<.001). All six performance measurements showed significant differences between genders, and the presence of an ISRTP had a significant interaction with gender with the 5-10-5 shuttle run, single leg horizontal leap, and the estimated 1RM leg press. The results of this study support implementation of an ISRTP for male basketball players. This study did not reveal benefits of female basketball players participating in an ISRTP during a collegiate varsity basketball season. The difference in gender responses of an ISRTP on collegiate basketball players may be due to a decrease in muscular strength that was observed in male non-ISRTP basketball players, but not male ISRTP, female ISRTP, or female non-ISRTP basketball players.
