Objective: The purpose of the study is to explore the sEMG characteristics of associated major muscle groups (agonist muscles) in curving-round-bridge-posts event of 400m obstacle and its relationship with muscle performance. Methods: This study tested seven male military cadets who did quite well in 400m obstacle, and analyzed the original electromyography, iEMG and iEMG% data by using the surface electromyography telemetry and anatomical analysis of the action, combined with sEMG synchronal video data analysis. Results: The power order of the muscle strength in left upper limb and trunk muscle groups is: all test muscle groups are almost synchronized muscle power; the power order of the left lower limb muscle group and rectus abdoninis in sequence is: rectus abdoninis and tibialis anterior first generate power, followed by quadriceps, hamstrings, gastrocnemius, and gluteus maximus in sequence. The order of iEMG and iEMG% from large to small is: the left upper limbs and trunk muscle groups (biceps brachii muscle, latissimus dorsi muscle, triceps muscle of arm, trapezius muscle, wrist flexors, deltoid muscle, pectoralis major muscle, and wrist extensors); the left lower limb muscle and rectus abdoninis (rectus abdoninis, hamstrings, gluteus maximus, quadriceps, gastrocnemius, and tibialis anterior). Conclusion: In the process of curving round the bridge posts, the key action is to rely on upper limb and shoulder-back power to get the body close to the bridge post to control inertial deviation. The left arm should be pull out as soon as possible to avoid motion delay, and to make sure the body may approach the bridge post as close as possible and move rapidly along the shortest route. In teaching and training of the curving-round-bridge-posts activity, great efforts should be made to develop the muscle strength of the upper limb biceps, brachialis, triceps muscle of arm, wrist flexors, latissimus dorsi muscle and trapezius muscle; focus should also be put on improving the muscle strength of the lower limbs hamstrings, gluteus maximus, quadriceps, triceps surae, and rectus abdoninis.
