The purpose of this study was to investigate the effect of surface height on muscular activity of triceps brachii and pectoralis major muscle during push-up exercise. Twenty-two healthy subjects were recruited and were asked to push-up exercise in four different surface height(0, 8, 13, and 20㎝). The push-up exercise was divided three stages which were holding in starting position, moving from starting position to final position, and holding in final position. We used surface electromyography to measure the activities of both triceps brachii and pectoralis major. We analyzed the data by using repeated one way ANOVA, the alpha level was 0.05. The results showed that the activity of triceps brachii and pectoralis major muscle is significantly different among four surface height in starting position and moving from starting position to final position. The activity of both triceps brachii is significantly different, however the activity of both pectoralis major is not significantly different holding in final position. The triceps brachii and pectoralis major muscle strength should be essential for transport in paraplegia patient. Therefore, the surface height in push-up exercises should use intensity factor of strengthen triceps brachii and pectoralis major.
