The purpose of this study was to determine the effect of two-hand backhand shots on wrist extensor and flexor muscle activation. Fourteen collegiate tennis athletes were participated in this study. The subjects does not have experiences of surgery on lateral epicondyle of elbow and musculoskeletal for at least last 6 months. The mean and standard deviation of data was calculated by SPSS/PC 18.0 and One-way ANOVA (post-hoc: LSD) was used to verify differences among groups. Significant level was p<.05. The results of this study were as follows; 1. There was significant difference on maximal value of muscle activation of extensor carpi ulnaris (D>S>V) and on maximal value of muscle activation of flexor carpi radialis(D>S>V) in male athletes by types of two-hand backhand shot(p<.05). 2. There was significant difference on maximal and average value of muscle activation of flexor carpi radialis(D>V>S) in female athletes by types of two-hand backhand shot(p<.05). In conclusion, this study suggests that beginers should learn a drive after aquiring the other skills to prevent their injuries since the level of muscle activation is higher than the others.

현대사회에 있어서 신체활동 연구의 주요 탐구과제는 ‘신체활동을 통한 교육’으로부터 ‘인간의 기본적인 움직임’을 목표로 하는 스포츠적인 움직임을 중심으로 한 생명 활동의 개념으로 급속히 변화되고 있는 추세이다. 이러한 환경변화에 대응하기 위하여 본학회는 ‘체육’적인 요소에서 ‘스포츠’적인 요소를 중심으로 한 학문적 정체성을 견고히 하고, 정기적인 학술지 발간과 학술활동을 통해 한국스포츠츠 문화의 발전과 학문적인 발전에 기여하는데 그 목적이 있다.
