The purpose of this study was to compare the impact of velocity-based resistance training (VBRT) and percentage-based resistance training (PBRT) on anaerobic ability, sprint performance, and jumping ability. Eighteen female basketball players from a Sport College were randomly divided into two groups: VBRT (n = 10) and PBRT (n = 8). The six-week intervention consisted of two sessions per week of free-weight back squats with linear periodization from 65% to 95%1RM. In PBRT, the weights lifted were fixed based on 1RM percentage, while in VBRT, the weights were adjusted based on individualized velocity profiles. The T-30m sprint time, relative power of countermovement jump (RP-CMJ), and Wingate test were evaluated. The Wingate test assessed peak power (PP), mean power (MP), fatigue index (FI), maximal velocity (Vmax), and total work (TW). Results showed that VBRT produced a very likely improvement in RP-CMJ, Vmax, PP, and FI (Hedges' g = 0.55, 0.93, 0.68, 0.53, respectively, < 0.01). On the other hand, PBRT produced a very likely improvement in MP (Hedges' g = 0.38) and TW (Hedges' g = 0.45). Although VBRT showed likely favorable effects in RP-CMJ, PP, and Vmax compared to PBRT ( < 0.05 for interaction effect), PBRT produced greater improvements in MP and TW ( < 0.05 for interaction effect). In conclusion, PBRT may be more effective in maintaining high-power velocity endurance, while VBRT has a greater impact on explosive power adaptations.
本研究的目的是比较基于速度的阻力训练（VBRT）和基于百分比的阻力训练（PBRT）对无氧能力、短跑成绩和跳跃能力的影响。来自一所体育学院的18名女篮球运动员被随机分为两组：VBRT组（n = 10）和PBRT组（n = 8）。为期六周的干预包括每周两次的自由重量深蹲训练，采用从65%到95% 1RM的线性周期化训练。在PBRT组中，举起的重量根据1RM百分比固定，而在VBRT组中，重量根据个体速度曲线进行调整。评估了30米短跑时间、反向移动跳的相对功率（RP-CMJ）和温盖特测试。温盖特测试评估了峰值功率（PP）、平均功率（MP）、疲劳指数（FI）、最大速度（Vmax）和总功（TW）。结果表明，VBRT组在RP-CMJ、Vmax、PP和FI方面有极有可能的改善（Hedges' g分别为0.55、0.93、0.68、0.53，P < 0.01）。另一方面，PBRT组在MP（Hedges' g = 0.38）和TW（Hedges' g = 0.45）方面有极有可能的改善。尽管与PBRT组相比，VBRT组在RP-CMJ、PP和Vmax方面显示出可能的有利影响（交互效应P < 0.05），但PBRT组在MP和TW方面有更大的改善（交互效应P < 0.05）。总之，PBRT在维持高功率速度耐力方面可能更有效，而VBRT对爆发力适应有更大影响。
