Abstract

The purpose of this study is to monitor the physiological changes by measuring EEG, blood pressure, heart rate, etc after applying progressive relaxation technique to university archery players in order to verify the effect of progressive relaxation through respiration, and, ultimately, improve an athlete's archery performance. This study chose 13 female archery athletes. The EEG, blood pressure, and heart rate of the athletes were measured before applying Jacobson's progressive relaxation technique for 12 weeks, during which the EEG, blood pressure, and heart rate were measured 3 times a week after 15 to 20 minutes of training before every measurement. We used the SPSS18.0 program for technical analysis to check the general features of the athletes and carried out the paired t-test to examine the changes made to the EEG, blood pressure, and heart rate of a single test group before and after the experiment. All statistical level of significance was maintained at ${\alpha}=0.5$. The results are as follows. First, after 12 weeks of appliance, between the targets' relative ${\alpha}$ wave and ${\beta}$ wave, the relative ${\alpha}$ wave showed a statistically significant increase while the relative ${\beta}$ wave showed no changes. Second, after 12 weeks of appliance, in terms of blood pressure, the systolic pressure showed no changes while the diastolic pressure showed a statistically significant change. Third, there was no statistically significant change to the heart rate. In conclusion, progressive relaxation through breathing has a positive effect on the archery athletes.

본 연구의 목적은 점진적 이완기법을 대학 양궁선수들에게 적용한 후 뇌파측정과 혈압, 심박수 등의 생리적인 변인의 측정을 통하여, 호흡을 통한 점진적 이완의 효과성을 검증하고 궁극적으로 양궁의 경기수행력을 향상시키는데 목적이 있다. 본 연구의 대상자들은 여자 양궁선수 13명을 대상자로 선정하였고, 12주간 Jacobson의 점진적 이완기법을 적용하여 1주일에 3일, 1회 약 15~20분 동안 훈련 후, 동일 대상자 13명의 뇌파와 혈압, 심박수를 측정하였다. 본 연구의 자료처리는 SPSS18.0프로그램을 이용하여 실험 대상자의 일반적인 특정을 알아보기 위하여 기술분석을 실시하였고 단일 집단의 뇌파, 혈압, 심박수의 사전 사후의 변화를 알아보기 위하여 대응 t-test(paired t-test)를 실시하였다. 모든 통계적 유의 수준은 ${\alpha}=0.5$로 하였고, 다음과 같은 결과를 얻었다. 첫째, 12주간 처치 후 상대 ${\alpha}$파, 상대 ${\beta}$ 중에서 상대${\alpha}$파가 통계적으로 유의한 수준으로 증가하였고, 상대 ${\beta}$파의 변화는 나타내지 않았다. 둘째, 12주간 처치 후 혈압의 변화로는 수축기압의 변화는 나타내지 않았고, 이완기 혈압의 변화가 통계적으로 유의한 수준으로 나타났다. 셋째, 심박수의 변화는 통계적으로 유의하게 나타나지 않았다. 이상의 결과를 종합하여 볼 때 호흡을 통한 점진적 이완기법은 대학 양궁선수들에게 긍정적인 영향을 미치는 것으로 나타났다.
