Abstract

The purpose of this study was to examine the relationship between the amount of muscle electrical activity and the change of speed in walking of healthy adults. The subjects of our study were 8 physically fit and healthy men whose ages ranged from 18 to 34 (23.1±6.4) years. The EMG signal was measured by the ME 3000 Professional System Muscle Tester (Mega Electronics Ltd). EMG activity in the right leg was measured through two surface electrodes on the belly of each muscle. The following muscles were monitored in all subjects : Gluteus medius, Gluteus maximus, Vastus lateralis, Biceps femoris, Tibialis anterior, Gastrocnemius, and Sacrospinalis. The series of tests consisted of seven speeds of walking, from 25 meters per minute to 175 meters per minute (25,50,75,100,125,150,175m/min). The results showed the following : 1) In general, integrated EMGs of each muscle for walking increased with increasing speed. Especially, the tibialis anterior showed a weak discharge at the 25m/min, and a strong discharge with increasing the speed up to 150m/min. However, at 175m/min, integrated EMGs of each muscle decreased. 2) Optimum speed of walking was supported in terms of the amount of muscle electrical activity elicited. The optimum speed of walking were ranged from 75m/min to 100m/min. Also, at the walking speed of 25m/min, integrated EMGs of each muscle attained the highest value.
