摘要: 为研究草原公路驾驶人腰部肌肉疲劳恢复特性,在草原公路模拟驾驶环境开展腰部疲劳恢复试验。利用MP150多通道生理测试仪采集驾驶人试验前、驾驶结束时和疲劳恢复阶段的腰部肌电信号,并应用配对样本t检验和独立样本t检验进行统计分析,探讨草原公路驾驶人腰部肌肉疲劳恢复特征。结果表明:在驾驶疲劳恢复期,时域指标平均振幅值(AEMG)、积分肌电值(IEMG)和均方根值(RMS)随恢复时间而增大,频域指标中位频率值(MF)和平均功率频率值(MPF)则随之减小;各指标在疲劳恢复初期恢复较快,当驾驶人疲劳恢复程度达到80%左右时,其在之后同等时间段内肌电各指标的恢复能力趋于平缓;2 h组腰部竖脊肌的表面肌电(sEMG)指标在恢复期第 18 min与静测无显著差异,4 h组在恢复期第27 min与静测无显著差异。

Abstract: To study the characteristics of recovery from waist muscle fatigue for drivers driving on the prairie highway,drivers' lumbar muscle recovery experiments were carried out in a simulated grassland highway driving environment.The waist electromyographic signal was collected before the test,the end of the driving and fatigue recovery phase by MP150 multi-channel physiological tester acquisition.The paired sample t-test and independent sample t-test statistical analysis were carried out,drivers waist muscle fatigue recovery characteristics were discussed on the prairie highway.The results show that there is a positive correlation between the time-domain indices (AEMG,IEMG and RMS of sEMG) and the recovery time,and there is a negative correlation between the frequency domain indices (MF and MPF) and the recovery time.Recovery rate is inversely proportional to recovery time.

Key words: prairie highway, traffic safety, recovery time, surface electromyography(sEMG), lumbar muscles, driving fatigue
