PURPOSE: To quantify and compare anthropometric and performance variables (i.e., counter movement jump (CMJ), lane agility, 10-yard sprint, and 300-yard shuttle run) between NCAA Division II men’s and women’s college basketball players. METHODS: Archived data for 30 (male=14; female=16) NCAA division II collegiate basketball players were used for this analysis. Anthropometric (height, weight, and wingspan) and performance (i.e., countermovement jump (CMJ), lane agility, 10-yard sprint, and 300-yard shuttle run) data were assessed. All data was analyzed using PASW software version 24.0 (SPSS Inc, Chicago, IL, USA). A series of Independent samples T-tests were used to determine significant differences between sexes. Effect sizes (d) calculation were also performed to determine the least amount of worthwhile difference. Statistical significance was set a priori (p < 0.05). RESULTS: Independent samples t-test revealed significant (p < 0.001) sex-related differences favoring males in all measured variables (CMJ height (29.74 ± 3.16in vs. 19.65 ± 2.11in; d = 3.76), 300yard shuttle run performance (55.93 ± 2.94s vs. 65.67 ± 3.64s; d = 3.06), lane agility (10.76 ± 0.61s vs. 12.04 ± 0.55s; d = 2.11) and 10-yard sprint times (1.67 ± 0.09s vs. 1.88 ± 0.08s; d = 2.58). CONCLUSION: These findings suggest that NCAA DII collegiate male basketball players perform better on measures of power, speed, and anaerobic endurance compared to their female counterparts. These sex-related differences are likely due to previous reports of larger type II fibers among males compared to females, resulting in greater cross-bridge activity during high-intensity efforts.
