Surface rms-EMG measurement as a real time monitoring method for detecting the anaerobic threshold during a bicycle ergometer test was evaluated and compared with blood lactate and ventilatory parameters. The study group consisted of 12 healthy ice hockey players. The anaerobic threshold indicated as dislinearity of increase in blood lactate level, ventilatory parameters and myoelectrical activity was observed at the work level of 300 (range 270-330) W in each case. The linearity disappeared at same time in the rms-EMG-load ratio both in working (quadriceps and gastrocnemius) and nonworking (frontalis) muscles. The rms-EMG follow-up was easier to perform than measurements of blood lactate and ventilatory parameters.
评估了表面均方根肌电图（rms-EMG）测量作为自行车测力计测试期间检测无氧阈的实时监测方法，并将其与血乳酸和通气参数进行了比较。研究组由12名健康的冰球运动员组成。在每种情况下，无氧阈表现为血乳酸水平、通气参数和肌电活动增加的非线性，在工作水平为300（范围270 - 330）瓦时观察到。在工作（股四头肌和腓肠肌）和非工作（额肌）肌肉中，均方根肌电图-负荷比的线性在同一时间消失。与血乳酸和通气参数的测量相比，均方根肌电图随访更容易进行。
