Relationships between Lower-body Power, Sprint and Change of Direction Speed among Collegiate Basketball Players by Sex.

The purpose of this study was to determine if significant relationships exist between absolute and relative lower-body power and selected measures of speed among male and female collegiate basketball players. Archived performance testing data from 29 (male = 14; female = 15) NCAA division II collegiate basketball players were used for this analysis. These measures included lane agility, 10-yard sprint, and shuttle run time (sec). A Pearson's correlation coefficient was used to determine if significant relationships existed between measures of lower-body power and linear sprint time, change of direction speed (CODS), and shuttle performance. Statistical significance was set at ≤ 0.05. A significant large correlation was found between absolute power and lane agility ( = 0.54, = 0.05) among male players. No significant correlations were found between absolute or relative power for 10-yard sprint times, lane agility, or shuttle run performance ( > 0.05). Females showed no significant correlations between relative power and lane agility ( = -0.25, = 0.37) or 10-yard sprint ( = -0.47, = 0.08), but did show a significant large correlation ( = -0.64, = 0.01) between relative power and shuttle run performance. Generating high amounts of relative power is vital in intermittent team sports such as basketball. In particular, this study provided evidence that relative power in female collegiate basketball players is significantly related to shuttle run ability.
