12주간 축구운동프로그램이 중학생의 건강관련체력과 혈중지질 및 코티졸 변화에 미치는 영향

Abstract

본 연구의 목적은 12주간 축구운동프로그램이 중학생의 건강관련체력, 혈중지질과 코티졸에 미치는 변화를 규명하고자 하였다. 본 연구는 중학생 14명을 선정하여 운동군 (N=7), 통제군 (N=7)으로 구분하였다. 축구운동프로그램은 12주간 주 3일, 120분으로 최대심박수의 50～80%의 강도로 실시하였다. 측정항목은 건강관련체력(근력, 근지구력, 유연성, 심폐지구력, 신체조성), 혈중지질(TG, TC, HDL-C, LDL-C), 코티졸의 수준을 사전과 사후에 각각 검사하였다. 본 연구는 SPSS프로그램을 사용하여 평균 및 표준편차를 산출하였고, 가설검정을 위하여 대응표본 t-test와 독립표본 t-test을 사용하였으며, 가설검정을 위한 유의수준은 α=.05로 설정하였다. 본 연구의 결과 근력, 유연성, 체중, BMI, 근육량, 체지방률, WHR은 운동군내에서 유의하게 개선되었다. 그러나, 혈중지질은 12주 후 유의한 차이를 나타내지 않았다. 한편, 코티졸은 12주 후 운동군내에서 뿐만 아니라 운동군과 통제군간에도 유의한 차이를 나타내였다. 이상의 결과를 종합해 보면, 본 연구의 축구운동프로그램은 중학생의 신체조성을 향상시킬 뿐만 아니라 코티졸의 농도를 감소시킬 수 있었다.

The purpose of this research was to examine the effect of 12 weeks soccer exercise program on health-related physical fitness, blood lipids and cortisol in middle school students. 14 subjects were divided into exercise (N=7) and control (N=7) groups. Soccer exercise program was carried out under the condition of 50～80% of HRmax for 120 minutes, 3 days a week for 12 weeks. Health-related physical fitness (muscle strength, muscular endurance, flexibility, cardio-respiratory endurance, body composition), blood lipids (TG, TC, HDL-C, LDL-C) and cortisol of all subjects were measured before and after the experiment participation. All data were expressed as mean and standard deviation and also paired and independent t-test was performed to test the significant levels of differences within and between groups by using SPSS program. Significance was set at the α=.05. Consequently, muscle strength, flexibility, body weight, BMI, muscle mass, % body fat, WHR were significantly enhanced within exercise group after application of soccer exercise program. However, blood lipids were not shown that there were any significant differences within and between group. On the other hand, cortisol was significantly decreased within exercise group, and exercise group was shown that there was significant difference of cortisol, compared with control group. In summary, when considering the above results, soccer exercise could improve the levels of body composition. Futhermore soccer exercise program could decrease the concentration of cortisol in middle school students.
