Topik: manual handling task; sex differences Fulltext: 1254.pdf (201.9KB) Isi artikel The purpose of this study was to examine the sex differences in physiological and psychological load during manual handling task. Twelve male and eleven female university students participated in this study. Each participant performed 4 different manual handling tasks (lifting, lowering, twisting and carrying a box). The box was 43cm in width, 23.5cm in depth and 32.5cm length. The weight of the box was 6kg. For the lifting task, participants lifted the box from the floor to the table which was at a height of 70cm from the floor. For the lowering task, participants lowered the box from the table to the floor. For the twisting task, participants transferred the box on the table of the right or left sides of their body to the table of the other side with twisting the trunk. The carrying task included lifting the box from the floor, carrying the box through the given distance (5m) and placing the box on the table. During each task, surface EMG was derived from the biceps brachii, trapezius, erector spinae and rectus femoris muscles. To obtain heart rate value, ECG was derived from chest CM5 position. Psychological load was measured with the modified Borg scale after each task. The results showed that the %EMG value on trapezius muscle in females were significantly higher than that of males for all tasks. In the lifting and carrying tasks, the %EMG value of biceps brachii in females was significantly higher than that of males. There was no sex difference in heart rate value for each task. Except for twisting task, the rating of the modified Borg scale in females was significantly higher than that of males. The sex differences in physiological and psychological load during manual handling task are discussed for workstation design implication.
