대학 테니스 선수의 체력 및 등속성 근기능 분석 연구

Abstract

This study was to evaluate the physical fitness and isokinetic muscular strength of university tennis players comparing to different exercise players. 10 male tennis players, 10 male volleyball players and 10 male handballl players those were engaged in H and S university were participated. Physical fitness was composed of grip strength, back strength, sit-up, vertical jump, close eyes foot balance and sit and reach. Cybex 770 was used to measure knee extension/flextion strength. Angle velocity was peak torque, %BW peak torque at 60o/sec, average power, %BW average power at 180o/sec and total work done at 240o?sec and exercise was repeated by 5, 10 and 30 times respectively. In grip strength and sit and reach there was no difference in the groups. However, the values of back strength, sit-up and vertical jump of tennis players were significantly lowest in the groups (p<0.05). In isokinetic muscular strength, all the values of tennis players such as peak torque(Nm) of right knee extension/flextion, and left knee extension/flextion at 60o/sec were significantly lower than the other groups (p<0.05). And all the values of tennis players such as %BW peak torque (%) of right and left knee extension/flextion at 60?sec were only significantly lower at right than the other groups (p<0.05). In isokinetic muscular strength, all the values of tennis players such as average power(Watt), average power (%) of right and left knee extension/flextion at 180?sec were significantly lower than the other groups (p<0.05). In isokinetic muscular strength, all the values of tennis players such as total work done of right and left knee extension/flextion at 240?sec were only significantly lower at flextion than the other groups (p<0.05). It means that the levels of physical fitness and isokinetic muscular strength were dependent on exercise pattern of players. However, the tennis players need more training to improve their fitness level in order to get better performance. Since there was no previous result to compare our data for university tennis players, further research on tennis players will be needed in the future.
