The aims of the current study were to analyze a kick from 10 m in a futsal context and the parameters of muscular strength using an isokinetic dynamometer in a laboratory environment, performed with the dominant (DL) and nondominant lower limbs (NDL). Seventeen professional elite players participated. Kicking performance was evaluated from the second penalty mark. Next, athletes completed a strength evaluation with an isokinetic dynamometer at speeds of 60°⋅s, 180°⋅s, and 300°⋅s. Significant differences were observed for hip (15.64 ± 3.44; 13.97 ± 2.62), ankle (63.19 ± 8.90; 52.55 ± 8.72), foot (82.31 ± 7.93; 68.41 ± 7.85), and ball (99.74 ± 8.45; 88.31 ± 7.93) speeds (km⋅h), and average power at 180°⋅s (325.59 ± 40.47; 315.79 ± 39.49 W), but not for accuracy (1.33 ± 0.57; 1.66 ± 0.77 m) between the DL and NDL, respectively. Few moderate correlations were observed in the DL (r = .54-.64) or NDL (r = .53-.55) between the kinematic variables of kick and muscular strength parameters (P < .05). We conclude that highly trained players present asymmetries in kicking motion; however, the imbalance in muscular strength is very small. We recommend that specific court tests be conducted to reliably characterize kicking performance in futsal. Success in kicking seems to be too variable and complex to be totally predicted only by joints, foot and ball speed, and lower limb muscular strength parameters.
本研究的目的是在室内五人制足球环境中分析10米处的一次踢球动作，并在实验室环境中使用等速测力计测量优势下肢（DL）和非优势下肢（NDL）的肌肉力量参数。17名职业精英球员参与了研究。从第二个罚球点评估踢球表现。接下来，运动员以60°·s、180°·s和300°·s的速度使用等速测力计完成力量评估。观察到髋部（15.64±3.44；13.97±2.62）、脚踝（63.19±8.90；52.55±8.72）、足部（82.31±7.93；68.41±7.85）和球的速度（千米·小时）以及180°·s时的平均功率（325.59±40.47；315.79±39.49瓦）存在显著差异，但DL和NDL之间的准确性（1.33±0.57；1.66±0.77米）没有显著差异。在DL（r = 0.54 - 0.64）或NDL（r = 0.53 - 0.55）中，踢球运动学变量与肌肉力量参数之间观察到少数中等程度的相关性（P < 0.05）。我们得出结论，训练有素的球员在踢球动作中存在不对称性；然而，肌肉力量的不平衡非常小。我们建议进行特定的场地测试，以可靠地表征室内五人制足球中的踢球表现。踢球的成功似乎过于多变和复杂，无法仅通过关节、足部和球的速度以及下肢肌肉力量参数完全预测。
