Abstract

BACKGROUND

Soccer players' leg muscular strength and power have been shown to be significant due to their association with soccer-specific performance including jumps, sprints, tackles and kicks. The aim of this study, therefore, was to examine the effects of an in-season in-field variable resistance training (VRT) program on strength, power, and anthropometry of junior soccer players.

METHODS

A team of male soccer players were randomly assigned into Experimental (N.=10) and Control groups (N.=10). The Control group performed 8 weeks of soccer training alone. The Experimental group performed squat VRT using chains in addition to soccer training. Measures before and after training included squat strength, countermovement jump, and anthropometric estimation of thigh muscle cross sectional area (CSA).

RESULTS

The VRT induced large improvements in absolute (34.45%; P=0.001; Cohen's d=1.78) and relative strength to thigh muscle CSA (21.53%; P=0.002; Cohen's d=1.04). Similarly, there were large (18.07%, P=0.007; Cohen's d=1.5) increases in jump height and medium gains in absolute peak power output (16.13%; P=0.009; Cohen's d=0.34) and relative peak power output to thigh muscle CSA (9.6%; P=0.002; Cohen's d=0.31). Further, there was a medium increase (5.9%, P=0.03; Cohen's d=0.36) in thigh muscle CSA. No significant changes were observed in the Control group.

CONCLUSIONS

In-season in-field biweekly squat VRT enhanced strength and power measures in junior soccer players.

摘要

背景

足球运动员的腿部肌肉力量和爆发力已被证明至关重要，因为它们与包括跳跃、短跑、铲球和踢球在内的特定足球表现相关。因此，本研究的目的是检验赛季内场地可变阻力训练（VRT）计划对青少年足球运动员的力量、爆发力和人体测量学的影响。

方法

一组男性足球运动员被随机分为实验组（N = 10）和对照组（N = 10）。对照组仅进行8周的足球训练。实验组除足球训练外，还使用链条进行深蹲VRT训练。训练前后的测量指标包括深蹲力量、反向移动跳跃以及大腿肌肉横截面积（CSA）的人体测量估计。

结果

VRT训练使绝对力量（提高34.45%；P = 0.001；科恩d值 = 1.78）和相对于大腿肌肉CSA的相对力量（提高21.53%；P = 0.002；科恩d值 = 1.04）有大幅改善。同样，跳跃高度大幅增加（18.07%，P = 0.007；科恩d值 = 1.5），绝对峰值功率输出中等增加（16.13%；P = 0.009；科恩d值 = 0.34），相对于大腿肌肉CSA的相对峰值功率输出增加（9.6%；P = 0.002；科恩d值 = 0.31）。此外，大腿肌肉CSA有中等程度增加（5.9%，P = 0.03；科恩d值 = 0.36）。对照组未观察到显著变化。
