The purpose of the study was to evaluate the influence of neuromuscular electrical stimulation (NMES) on a roundhouse kick (RHK) and the rate of force development (RFD) and peak force during maximal isometric contractions with the knee extensors. Sixteen martial arts athletes were randomly assigned to either a training group (NMES + martial arts) or a control group (martial arts). The RHK was performed to a fixed target located approximately 1.5 m away from the athlete. The reaction time and execution time were quantified with a light-sensor system. Participants were tested before and after completing 15 sessions of training (5 weeks, 3 sessions/week, 90 min/session). In addition, the training group performed another 15 sessions (3 sessions/week, 30 min/session) in which electrical stimulation was superimposed on maximal isometric contractions of the quadriceps (100 Hz, 450 μs). There were no statistically significant changes in either RFD or maximal isometric force for either group ( > 0.05). However, the training group experienced significant reductions ( < 0.05) in both reaction time (-9.2%) and the execution time (-5.9%). The findings indicate that supplemental NMES training can improve sport-specific movements, such as the RHK, without any changes in maximal force capabilities in skilled martial arts athletes.
本研究的目的是评估神经肌肉电刺激（NMES）对旋踢（RHK）以及膝关节伸肌最大等长收缩过程中的力量发展速率（RFD）和峰值力量的影响。16名武术运动员被随机分为训练组（NMES + 武术训练）或对照组（仅武术训练）。向距离运动员约1.5米处的固定目标进行旋踢。使用光传感器系统对反应时间和执行时间进行量化。参与者在完成15节训练课程（5周，每周3节，每节90分钟）之前和之后接受测试。此外，训练组还进行了另外15节课程（每周3节，每节30分钟），其中电刺激叠加在股四头肌的最大等长收缩上（100Hz，450μs）。两组的RFD或最大等长力量均无统计学上的显著变化（P>0.05）。然而，训练组的反应时间（-9.2%）和执行时间（-5.9%）均有显著缩短（P<0.05）。研究结果表明，补充性NMES训练可以改善特定运动动作，如旋踢，而不会改变熟练武术运动员的最大力量能力。
