Abstract :Objective:Obrving the effect of different surface temperatures of skeletal muscles on the surface EMG signals is of great significance for understanding the mechanism of changes in surface EMG signals during human exerci,especially exerci fatigue.Methods:Taking 11male college students were ud to make the surface muscle of the left biceps brachii muscle contract at different temperatures by three different methods:heating,ice compress and room temperature,u the ME6000surface electromyograph to collect the surface EMG signal of the left arm biceps.For tim
e domain indicators,integrated electromyography (IEMG),root mean square amplitude (RMS),frequency domain indicators mean power frequency (MPF)and median frequency (MF)For analysis.Results:The amplitude of the time domain indicators RMS and IEMG at the surface temperature of 16℃is significantly higher than the average of 35℃and 42℃(P <0.01),while the amplitude of the frequency domain indicators MF and MPF at 16℃is higher than 35℃,Significantly decread at 42℃(P <0.01).Conclusion:As the
skin surface temperature decreas,the time domain indicators IEMG and RMS show a significant upward trend,while the frequency domain indicators MPF and MF show a significant downward trend.It can be en that the skeletal muscle temperature has an effect on the time and frequency domain indicators of myoelectricity May affect the judgment of muscle fatigue on the surface EMG signal.Key words:surface electromyography;superficial muscle temperature;IEMG;RMS;RMS;MF ··48加油 日语>inc
