This study evaluated the possible benefits of year-round strength training for male intercollegiate basketball players. Eight players were evaluated four times (T1-T4) during a 12-month period. Test items included body weight, body composition, the Margaria-Kalamen Stair Test, vertical jump, and 1-RM bench press. The repeated-measures ANOVA technique was used to test for significant differences across test scores. Percent body fat consistently decreased over time (p<.05), while body weight decreased (p<.05) from T1 to T2 and then gradually returned to the T1 level by T4. This shift toward a higher percent lean body mass might explain a 27.5-lb mean 1-RM bench press gain over the same time period. Correlational analyses indicated that the positive relationship of weight to strength decreased from r = 0.33 to r = 0.04, indicating that size is less of a predictor of strength when strength training supplements traditional basketball training. Vertical jump and stair test mean scores did not change significantly. Results suggest there are physical and physiological benefits associated with year-round strength training for male intercollegiate basketball players, although control data were not available.
