This study used the EMG (electromyography) machine telemeter System WEB- 1000 to record the muscle activity and the sampling rate 1,000 Hz was used as the record condition of the bamboo moisture by immersed bamboo in water on 4-hour and 3-day would affect the muscle activity during separated bamboo by bending process Thirteen muscles which bilateral side of Pectoralis major, Biceps brachii, Triceps brachii, Latissimus dorsi, Gluteus medius and only right side of Rectus abdominis, Extensor carpi radialis longus and Flexor carpi radialis were recorded As a result, the bilateral side of Biceps brachii, right side of Extensor carpi radialis longus and Flexor carpi radialis, left side of Triceps brachii showed the difference quite clearly When the craftsman was bending the bamboo he was necessary more effortful by these muscles activity on the 4-hour immersed bamboo in water than the 3-day
