The major objective of the study was to compare Right External oblique muscle activity by surface electromyography (EMG) include others trunk and upper limb muscle activities in male badminton players of different performance levels between aged 18-30 years old. Twenty-eight badminton players were classified into 2 groups as 14 high skilled badminton players and 14 low skilled badminton players. All badminton players must perform 3 characteristics of smash stroke; including forehand smash stroke, backhand smash stroke and overhead smash stroke. Thirty trials of each smash stroke characteristic were experimented. Therefore each player were required to perform 90 trials in the cross court smash stroke. The results demonstrated no statistically significant difference in EMG activity of trunk and upper limb muscles between male badminton players of different performance levels. (p < 0.05) It was found that the shuttlecock velocity at impact of forehand, backhand and overhead smash stroke of high skilled badminton players were significantly greater than low skilled badminton players. (p < 0.05). X-factor and X-factor stretch at the moment of impact were analyzed and found that high skilled badminton players had X-factor and X-factor stretch less than low skilled badminton players, but no statistically significant difference. (p < 0.05)
