A specially instrumented bicycle ergometer is utilized in this investigation to induce reproducable loading conditions on the muscles of the lower extremity at different speeds. Various tehcniques for evaluating the electromyographic signals from the vastas medialis muscle are investigated for different load and speed conditions and shown to be essentially equivalent. The RMS signal power computed by means of a real time spectral analyzer is shown to be a convenient means of quantification of the dynamic EMG signals. The electromyographic signals are shown to be stable under repeated static or dynamic conditions but not under sustained isometric static loading.
在本研究中，使用了一种特殊的仪器化自行车测力计，以在不同速度下对下肢肌肉施加可重复的负荷条件。针对不同的负荷和速度条件，研究了评估股内侧肌肌电信号的各种技术，并表明它们基本等效。通过实时频谱分析仪计算得到的均方根信号功率被证明是量化动态肌电信号的一种便捷方法。肌电信号在重复的静态或动态条件下是稳定的，但在持续的等长静态负荷下则不稳定。
