The purpose of the present study was to examine the effects of stabilization training on trunk muscularity and physical performances in youth male soccer players aged 12-13 yrs (n = 28). The subjects allocated to training (TG, n = 16) performed a stabilization exercise program consisting of 5 exercises (elbow-toe, elbow-heel, side bridge, modified 1-legged squat, and bent-knee push-up) 4 times per week and a training program specific to soccer 6 times per week, whereas the others (control, n = 12) conducted the soccer training only for 6 months. Before and after the intervention, the cross-sectional areas (CSAs) of 5 muscles (rectus abdominus, oblique, psoas major, quadratus lumborum, and erector spinae) were determined using magnetic resonance imaging. Furthermore, peak torques during hip extension and flexion at 1.05 rad/second, heights of squat and countermovement jumps, and time taken to sprint 15 m were also measured. After 6 months, both groups significantly increased the CSAs of the 5 muscle groups (TG: 4.4-13.4%, control: 5.5-10.9%) and improved sprint time (TG: -1.4%, control: -1.6%), without significant effect of group, but only TG significantly increased the heights of squat (5.0%) and countermovement (6.8%) jumps. In addition, a greater increase in hip extension torque was found in TG (40.8%) than in control (17.4%). The current results indicate that, at least in early adolescent soccer players, adding stabilization exercise to soccer training cannot increase the trunk muscularity, but it will improve hip extensor strength and vertical jump performance.
本研究旨在探讨稳定性训练对 12-13 岁青少年男性足球运动员躯干肌肉力量和身体表现的影响。将受试者分为训练组（TG，n=16）和对照组（n=12）。训练组进行 5 项稳定性练习（肘对趾、肘对脚跟、侧桥、改良单腿深蹲和屈膝俯卧撑），每周 4 次，足球专项训练每周 6 次；对照组仅进行 6 个月的足球训练。干预前后，使用磁共振成像（MRI）确定 5 块肌肉（腹直肌、斜肌、腰大肌、竖脊肌和腰方肌）的横截面积（CSA）。此外，还测量了髋关节伸展和屈曲时的峰值力矩（1.05 rad/s）、深蹲和反向跳的高度，以及冲刺 15 米的时间。6 个月后，两组的 5 块肌肉 CSA 均显著增加（TG：4.4-13.4%，对照组：5.5-10.9%），冲刺时间也显著缩短（TG：-1.4%，对照组：-1.6%），但组间无显著差异，仅 TG 组的深蹲（5.0%）和反向跳（6.8%）高度显著提高。此外，TG 组髋关节伸展力矩的增加幅度（40.8%）大于对照组（17.4%）。结果表明，在青少年足球运动员中，至少在早期，将稳定性训练加入足球训练并不能增加躯干肌肉力量，但能增强髋关节伸肌力量和垂直跳跃能力。
