Lower limb strength and muscular balance are important attributes in the practice of Taekwondo.
To assess through isokinetic dynamometry the muscular strength and balance of knee extensor and flexor apparatus of elite Taekwondo athletes and to compare with recreational-type athletes.
The maximum torque, the angle of maximum torque, maximum torque work, total work of the series, average power, and flexor and extensor muscle apparatus balance of the knees were obtained.
A total of 32 knees were studied. Significantly higher values in peak torque and total work of the series were present in the group of TKD athletes in the extensor muscles, while the maximum torque angle of extensor and flexor muscles was higher in controls. We found a muscular imbalance due to flexor muscle strength deficit in both groups.
Higher levels of muscular strength and an imbalance between the knee flexor and extensor muscle groups characterized the predominant motor gesture of TKD athletes. These results are useful in the design and implementation of training programs, to optimize the value of muscular strength and muscle balance in TKD athletes directed to promote optimal athletic performance and prevent sport-related injuries.
下肢力量和肌肉平衡是跆拳道运动中的重要属性。
通过等速测力法评估精英跆拳道运动员膝关节伸肌和屈肌装置的肌肉力量和平衡，并与休闲型运动员进行比较。
获取膝关节的最大扭矩、最大扭矩角度、最大扭矩功、系列总功、平均功率以及屈伸肌装置平衡。
共研究了32个膝关节。跆拳道运动员组伸肌的峰值扭矩和系列总功显著更高，而对照组伸肌和屈肌的最大扭矩角度更高。我们发现两组均存在因屈肌力量不足导致的肌肉失衡。
更高水平的肌肉力量以及膝关节屈肌和伸肌肌群之间的失衡是跆拳道运动员主要运动姿态的特征。这些结果有助于训练计划的设计与实施，以优化跆拳道运动员的肌肉力量和肌肉平衡，促进最佳运动表现并预防运动相关损伤。
