야구는 던지고(Throw), 치고(Hit), 받는(Catch) 세 가지의 주요 동작으로 구성된 체력의 모든 요소가 필요한 스포츠 종목으로서 최근 국내 야구가 올림픽과 같은 국제대회에서 좋은 성적을 거두고 있어 유소년시기부터 야구를 시작하는 어린 선수들이 많아지고 있다. 운동은 궁극적으로 활동에너지 소비량의 증가를 통해 일반 어린이들에게는 인체 내부 환경(호르몬, 골대사 등)을 바람직하게 조성시켜 신장 발육에 긍정적인 영향을 줄 수 있으며(박동호 등, 2002), 또한 비만아의 체지방 및 성장 패턴 등의 변화를 주어 성장 저하를 예방할 수 있다(Kemper, Post, Twi나, 1997). 또한 박일봉(2002)은 야구운동이 초등학생들에게 근력과
This study was for the analysis of EMG(electromyography) change of elementary school baseball players according to career. For the performance of this study, subject was done dividedly 5 trained group, 5 non-trained group and 5 control group. In that result, it was shown that EMG value at deltoid, latissimus dorsi & pectoralis major significantly increased control group rather than trained & non-trained groups, at extensor carpi radialis & flexor carpi ralialis significantly increased trained & non-trained groups rather than control group in arm-cocking phase. In arm acceleration phase, there was significantly increased at deltoid & biceps significantly increased control group rather than trained & non-trained groups and extensor carpi radialis & flexor carpi radialis was significantly increased trained & non-trained groups rather than control group. lastly, there was significantly increased control group rather than non-trained groups at deltoid in deceleration phase. ※ Key words : EMG, Elementary Shool Baseball Player
