Abstract

The purposes of this project is to establish information on risk factors pertaining to discomfort and muscle fatigue associated with prolonged standing; analyse muscle activity of passengers while riding moving train in prolonged standing. The questionnaire was distributed to KTM Komuter Berhad passengers to establish information on risk factors relating discomfort and muscle fatigue. A Surface Electromyography (sEMG) was used to measure and analyze muscle activity in the erector spinae, gastrocnemius, and tibialis anterior inside the train. A total of 20 students participated as subjects for sEMG measurement. The muscle activity of the subjects was measured for 1 hours and 30 minutes of continuous standing during the beginning of travel, middle of travel, and end of travel in KTM Komuter Berhad which travel along 18 stations from Pulau Sebang/Tampin station to KL Sentral station. The results of the questionnaire surveys revealed that all respondents experienced psychological fatigue due to prolonged standing in a moving train. Similarly, muscle fatigue has been identified through sEMG measurement and according to the results of the myoelectric level, only one muscle which is right gastrocnemius muscle did not experience fatigue during all travel sessions. The nonparametric statistical test using the Spearman’s rank order correlation found that there is a positive correlation between subjective fatigue and muscle fatigue. The study concluded that standing in a long period of time is a cause of muscle fatigue experienced by the passengers while riding moving train in prolonged standing. Results of this study can provide awareness to the passengers in order to minimize discomfort and muscle fatigue when traveling using KTM Komuter Berhad.
