Abstract

The purpose of this study is to compare muscle activity of the upper limbs muscles and erector spine in cadet national athlete according to the shooting distance. In this study, participant of this study were selected one cadet national athlete to investigate the muscle activity. Draw arm extensor flexor digitorum superficialis (FDS), biceps brachii (BB), triceps brachii (TB), middle deltoid (MD), trapezius (TRA), erector spinae (ES) and Bow arm triceps brachii (TB), trapezius (TRA), erector spinae (ES) of muscle measured with surface electromyography (EMG). The results obtained from the study are as follows. The results of average muscle activity, 1. In the TRA of bow arm, 60 m was higher then the 30 m the drawing phase. 2. In the MD of bow arm, 30 m was higher then the 60 m the back-tension phase. 3. In the MD of draw arm, 30 m was higher then the 60 m the shooting phase. 4. In the FDS of draw arm, 60 m was higher then the 30 m the release phase. In addition, the results of maximum muscle activity, 1. In the MD of draw arm, 30 m was higher then the 60 m the drawing phase. 2. In the MD of bow arm, 30 m was higher then the 60 m the back-tension phase. 3. In the BB of draw arm, 30 m was higher then the 60 m the shooting phase. 4. In the TRA of draw arm, 60 m was higher then the 30 m the shooting phase. 5. In the FDS of draw arm, 60 m was higher then the 30 m the release phase. 6. In the BB of draw arm, 30 m was higher then the 60 m the release phase. 7. In the BB of bow arm, 30 m was higher then the 60 m the release phase.
