The Effect of Elastic Band Variable Resistance Training on the Explosive Power of Lower Limbs in College Basketball Athletes

Key Points

To investigate the effect of elastic band variable resistance training on explosive power in college basketball athletes.
Participants comprised 28 college basketball players randomly assigned to variable resistance training or traditional resistance training groups.
Training sessions occurred twice per week for 8 weeks, utilizing various jump tests and sprint measures to assess performance.
Analyses included comparisons of time effects and interactions between the training groups.
Significant improvements observed in explosive power measures for both training groups, but traditional resistance training did not yield significant group differences.
The time × group interaction effect was significant for the squat jump measure, indicating greater enhancement for the variable resistance training group.
No significant differences in the eccentric utilization rate across the training types.

Abstract

Abstract Dai, J, Liang, X, Wang, H, Lin, W, Sun, J, Li, D, and Wang, N. The effect of elastic band variable resistance training on the explosive power of lower limbs in college basketball athletes. J Strength Cond Res 39(8): e1003–e1009, 2025—The aim of this study was to investigate the impact of elastic band variable resistance training (VRT) on the explosive power of college basketball players. This study hypothesizes that elastic band VRT is superior to traditional resistance training (RT) in enhancing the lower limb explosive power of college basketball athletes. A total of 28 college basketball players specializing in basketball were randomly assigned to either the VRT group ( n = 14) or the traditional RT group ( n = 14). A training intervention was conducted twice per week, for a total of 8 weeks. Testing included the countermovement jump with arm swing (CMJA), countermovement jump (CMJ), squat jump (SJ), reaction strength index (RSI), eccentric utilization rate (EUR), standing long jump (SLJ), 10-meter sprint, squat 1 repetition maximum (1RM), and squat index (SI). The analysis of variance revealed significant time main effects for both the VRT group and the RT group in CMJA ( p 0.05). The time × group interaction effect was significant for the SJ measure ( p = 0.026), while it was not significant for the other measures ( p > 0.05). The effect of elastic band VRT on improving lower limb maximum strength is similar to that of traditional RT, but it is more effective in enhancing lower limb explosive power. Variable RT enhances the flexibility of RT regimens, resulting in more pronounced and enduring strength gains. When applying VRT, selecting the suitable intensity and techniques is crucial.
