本研究分析了跆拳道和自由搏击运动员膝关节伸展和屈曲的表现。功率值通过等速测功机在60A度/秒下获得的肌电图提取。这些值是由肌电信号的平方得到的。采用一种改进的小波算法，考虑具有95%显著性的值，对踢腿功率进行分析。两组在不同训练时间和训练经验下的力量和扭矩能力相当，另一方面，小波分析显示经验越丰富的运动员在肌肉招募表现上效果越好，即力量不仅是表现，而且力量加招募效果更好。该研究独特地表明，肌肉增强能力不仅与收缩的力量能力有关，而且与运动协调能力有关。
This study analyzes the performance of knee extension and flexion of Taekwondo and Kickboxing athletes. The power values were extracted through electromyography obtained by an isokinetic dynamometer at 60A degrees per second. These values are resulted from the square of the electromyography signal. The analysis of kick power was made using a modified wavelet algorithm considering values with 95% significance. Both groups presented equivalent power and torque capacity with different training times and experience, on the other hand, the wavelet analysis showed better results in muscular recruitment performance in athletes with more experience, in other words, power is not only performance but also power plus recruitment produces better results. This study uniquely showed that muscular enhancement capacity is not only related to the power capacity of contraction but also to motor coordination.
