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 60 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.
本研究分析了跆拳道和踢拳运动员的膝关节伸展和弯曲表现。通过等速测力仪以每秒 60 度的速度获取肌电图,提取出功率值。这些数值是由肌电图信号的平方得到的。通过考虑具有 95%显著性的数值的改进的小波算法对踢腿功率进行分析。两组都表现出不同训练时间和经验的等效功率和扭矩能力,另一方面,小波分析显示在经验更丰富的运动员中肌肉募集性能的结果更好,换句话说,力量不仅是表现,而且是力量加上募集可以产生更好的结果。这项研究独特地表明,肌肉增强能力不仅与收缩的功率能力有关,还与运动协调有关。
