The purpose of this study was to assess the effects of soccer training on strength and power of leg extensor muscles in preadolescent boys and their possible influence in developing a muscular lateral dominance. Twenty male children (mean age 9.6 yr), ten soccer players and ten untrained subjects, participated in this study. Force and power were measured at five constant cranking velocities on an isokinetic bicycle dinamometer. Each isokinetic load was given after each trial. Force and power outputs were calculated for each limb. Soccer players always showed higher and statistically significant differences (p < 0.05) for force and power values for all considered pedal frequencies. No significant differences were observed for force and power values between preferred and non preferred limb. The results demonstrate the effect of soccer training on the increase of force and power of both legs regardless of lateral dominance.
本研究的目的是评估足球训练对青春期前男孩腿部伸肌力量和功率的影响，以及其对形成肌肉侧优势的可能影响。二十名男性儿童（平均年龄9.6岁），十名足球运动员和十名未受过训练的受试者参与了本研究。在等动自行车测力计上以五种恒定的曲柄速度测量力量和功率。每次试验后施加每个等动负荷。计算每个肢体的力量和功率输出。对于所有考虑的踏板频率，足球运动员的力量和功率值总是显示出更高且具有统计学意义的差异（p <0.05）。在优势侧和非优势侧之间未观察到力量和功率值的显著差异。结果表明，无论侧优势如何，足球训练对双腿力量和功率的增加均有影响。
