This study explored the effects of an 8-week repeated backward running training (RBRT) programme on measures of physical fitness in youth male soccer players. Youth male soccer players were randomly allocated into a RBRT group ( = 20; 13.95 ± 0.22y) or a control group (CG; = 16; 14.86 ± 0.29y). The CG continued normal soccer training, while the RBRT group replaced some soccer drills with RBRT twice per week. Within-group analysis revealed that RBRT improved all performance variables (∆-9.99% to 14.50%; effect size [ES] = -1.79 to 1.29; ≤ 0.001). Meanwhile, trivial-to-moderate detrimental effects on sprinting and change of direction (CoD) speed (∆1.55% to 10.40%; ≤ 0.05) were noted in the CG. The number of individuals improving performance above the smallest worthwhile change ranged from 65-100% across all performance variables in the RBRT group, whereas<50% in the CG reached that threshold. The between-group analysis indicated that the RBRT group improved performance on all performance tasks more than the CG (ES = -2.23 to 1.10; ≤ 0.05). These findings demonstrate that substituting part of a standard soccer training regimen with RBRT can enhance youth soccer players' sprinting, CoD, jumping, and RSA performance.
本研究探讨了为期8周的重复向后跑训练（RBRT）计划对青年男性足球运动员体能指标的影响。青年男性足球运动员被随机分为RBRT组（n = 20；13.95 ± 0.22岁）或对照组（CG；n = 16；14.86 ± 0.29岁）。CG组继续进行常规足球训练，而RBRT组每周用RBRT替代两次足球训练。组内分析显示，RBRT改善了所有表现变量（变化幅度为-9.99%至14.50%；效应量[ES] = -1.79至1.29；P ≤ 0.001）。同时，CG组在短跑和变向（CoD）速度方面出现了轻微至中度的不利影响（变化幅度为1.55%至10.40%；P ≤ 0.05）。RBRT组中所有表现变量上，表现改善超过最小有价值变化的个体比例在65%至100%之间，而CG组中只有不到50%的个体达到该阈值。组间分析表明，RBRT组在所有表现任务上的表现改善均超过CG组（ES = -2.23至1.10；P ≤ 0.05）。这些发现表明用RBRT替代标准足球训练方案的一部分可以提高青年足球运动员的短跑、CoD、跳跃和反复冲刺能力表现。
