Abstract

The purpose of this study is to construct basic data for efficient technical training by investigating the difference in muscle activity during badminton technical movements involving jump motions similar to game situations. Seven male badminton players were randomly assigned to perform smash, drop, and clear techniques, and electromyograms were measured during the implementation of three technical movements. Measured EMG was calculated by RMS and one-way ANOVA was performed. The muscle activity of the smashing motion did not show any significant difference according to the site. In drop motion, activity of PM in the upper extremity muscles was lower than that of BC and ECR, and FCR activity was lower than that of EC. The activity of ECR was higher than that of PM and FCR. The activity of ES in trunk muscles was lower than that of RF and GM. RF activity of lower extremity muscles was higher than that of ES and BF. In clear motion, the activity of TC in upper extremity muscle was higher than FCR. The activity of ES in trunk muscles was lower than that of BF. RF activity of lower extremity muscles was higher than that of BF, and BF activity was lower than that of RF and GM. The activity of GM was higher than that of BF. As for muscle activity according to badminton skills, smash and drop motions were higher than clear motions in FCR, and clear motions were higher than smash and drop motions in RA. In conclusion, it is considered that muscle activity during the badminton game is different according to the characteristics of each skill, and FCR can affect the smash and drop, and RA can affect the clear motion.

이 연구는 경기상황과 유사한 점프 동작이 포함된 배드민턴 기술 동작 시 근육의 활성도의 차이를 조사함으로써 효율적인 기술훈련을 위한 기초자료를 구성하기 위한 목적이다. 남자 배드민턴 선수 7명을 대상으로 하여 스매시, 드롭, 클리어 기술을 무선배정으로 실시하였으며, 3가지 기술 동작 시행 중 근전도를 측정하였다. 측정된 근전도는 RMS로 산출하였으며 일원분산분석을 실시하였다. 스매싱 동작의 근활성도는 부위에 따른 유의한 차이를 보이지 않았다. 드롭 동작에서 상지 근육 중 PM의 활성도는 BC, ECR보다 낮았으며, FCR의 활성도는 EC보다 낮았다. ECR의 활성도는 PM, FCR보다 높았다. 몸통 근육 중 ES의 활성도는 RF, GM보다 낮았다. 하지 근육 중 RF의 활성도는 ES, BF보다 높았다. 클리어 동작에서 상지 근육 중 TC의 활성도는 FCR보다 높았다. 몸통 근육 중 ES의 활성도는 BF보다 낮았다. 하지 근육 중 RF의 활성도는 BF보다 높았으며, BF의 활성도는 RF, GM보다 낮았다. GM의 활성도는 BF보다 높았다. 배드민턴 기술에 따른 근활성도는 FCR에서 스매시와 드롭 동작이 클리어 동작보다 높았으며, RA에서 클리어가 스매시, 드롭 동작보다 높았다. 종합하면, 배드민턴 경기 중 근육활동은 기술별 특성에 따라 다르게 나타나고 노쪽손목굽힘근은 스매시와 드롭, 배곧은근은 클리어 동작에 영향을 미칠 수 있을 것으로 사료된다.
