Abstract

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
