8주간 수중훈련 프로그램이 고교 축구선수 등속성 근력 및 인스텝 킥의 수행력에 미치는 영향

Abstract

The purpose of this study is to show the effects of aquatic training with high school soccer player on in-step shooting speed and accuracy of kick, muscle strength of lower extremities and balance. The subjects of this study were 9 high school-soccer players with a career more than 6 years and they participated in aquatic training for 8 weeks before and after, that the study consist of in-step shooting speed, accuracy of in-step kick, isokinetic strength of ankle and knee joint and balance. We used SPSS 12.0 in order to analyze the results through the research, and compared the measurement subject by using the standard deviation of the mean. In addition, we did paired 2-sample non-parametic test for comparison of variables before and after the experiment and Spearman's Bivariate Correlation Analysis for relationship of respective variables. The level of significance is set up to 0.05 The results of the study were as follows ; 1. In the shooting speed was significantly differentiated pre and post-test(p<.05). 2. In the accuracy of in-step kick was significantly differentiated pre and post-test(p<.05). 3. In the muscle strength of knee flexor and extensor were improvement pre and post but not significantly differentiated. In the muscle strength of ankle dorsiflexor and plantarflexor were significantly differentiated(p<.05). 4. In the one leg standing, muscle strength of the left leg was improvement but not significantly differentiated and the right leg was significantly differentiated(p<.05). 5. Right ankle plantarflexor was significantly differentiated with exercise performance of in-step kick pre and post(p<.05), balance was significantly differentiated with high and mean speed pre and post(p<.05). Therefore, based on the result, it is indicated that the aquatic training had a positive effect on the shooting speed, accuracy of kick, muscle strength of lower extremities and balance. It is considered that give helps to improve ball speed and accuracy.
