테니스 웨스턴과 세미웨스턴 그립 간 근 협응 분석

Abstract

This research aimed to examine the effects of western grip and semi-western grip on muscle coordination change among the members of the Korean tennis national team. Conclusions are as follows. First, there were differences in muscle coordination sequences between western grip and semi-western grip across P1, P2, and P3 periods. For the P1 period, the same muscle manifestation sequence was observed with right-sided latissimus dorsi muscle. For the P2 period, the same muscle manifestation sequence was observed with backbone erector. For the P3 period, however, the same muscle manifestation sequence was not observed. Second, although changing from western grip to semi-western grip for forehand strokes resulted in different muscle manifestation sequences, it did not affect motor actions because of balances among agonistic muscle, antagonist muscle, and synergic muscle when doing a same action. In conclusion, this research shows that it is not easy to obtain deep understanding about muscle coordination and generalize the results. But an important point is that this research provides basic data for clarifying the coordination relationship between agonistic muscle and antagonist muscle. Based on this set of data, it is hoped that future research can examine what happens before and after athletes’ injuries more in depth.
