본 연구는 12주간의 트램폴린 운동이 PAPS, 혈중지질, 성장관련 호르몬에 미치는 영향을 구명하기 위하여 과체중 남자 중학생을 대상으로 운동군(n=13), 대조군(n=12)으로 구분하여 실시하였다. 트램폴린 운동은 주 3회, 회당 45분으로 운동 강도는 1-2주는 41-50%HRR (RPE 9-10), 3-4주는 51-60%HRR(RPE 11-12), 5-12주는 61-70%HRR(RPE 13-14)의 강도로 설정하였다. 측정변인들에 대한 그룹 및 시기 간 상호작용을 검증하기 위해 two-way repeated measures ANOVA로 처리하였고, 측정된 자료의 그룹 내 차이는 paired t-test, 그룹 간 차이는 independent t-test를 실시하였으며, 통계적 유의수준은 .05로 설정하여 분석하였다. 그 결과 PAPS의 경우 그룹 내 비교 시 운동군의 심폐지구력(p<.001), 유연성(p<.01), 순발력(p<.01)은 유의하게 증가하였고, 체지방률(p<.05)은 유의하게 감소하였다. 그룹 간 비교 시, 12주간 운동 후 운동군의 심폐지구력(p<.05), 순발력(p<.01)이 대조군보다 유의하게 증가하였고, 심폐지구력(p<.01), 순발력(p<.05), 체지방률(p<.05) 변화량에서 유의한 차이가 나타났으며, 심폐지구력(p<.01), 유연성(p<.05), 순발력(p<.05)에서 그룹×시기 간 상호작용 효과가 나타났다. 혈중지질의 경우 그룹 내 비교 시 운동군의 TC(p<.001), HDL-C(p<.01), LDL-C(p<.01)은 유의하게 감소하였다. 그룹 간 비교 시, 12주간 운동 후 운동군의 TC(p<.01), LDL-C(p<.01)가 대조군보다 유의하게 감소하였다. 성장관련 호르몬의 경우 그룹 내 비교 시 운동군의 성장호르몬(p<.05)은 유의하게 증가하였고, IGF-1은 유의한 차이가 나타나지 않았다. 따라서 본 연구의 결과를 통해 12주간의 트램폴린 운동이 과체중 남자 중학생의 PAPS, 혈중지질, 성장호르몬에 긍정적인 영향을 미친 것으로 사료된다.
The purpose of this study was to analyze the effects of trampoline exercise on PAPS (physical activity promotion system), blood lipids, and growth related hormones in overweight male middle school students by dividing them into a combined exercise group (n=13), and control group (n=12). This program included a 45-minute trampoline exercise three times a week with the following different intensities: Exercise intensity was 41-50%HRR (RPE 9-10) in week 1 to 2, 51-60%HRR (RPE 11-12) in week 3 to 4, and 61-70%HRR (RPE 13-14) in week 5 to 12. For the comparison of the mean value differences in each item before and after 12-week exercise, a paired t-test was used to analyze the within-group differences, and two-way repeated measures ANOVA was used to test the interactions between each period in the combined exercise group and control group. An independent t-test was used to test differences between the combined exercise group and control group. The alpha level of p<.05 was set for all tests of significance. The findings of this study were as follows. First, the results of PAPS showed that cardiovascular endurance, flexibility and power significantly increased and percentage of body fat significantly decreased in the exercise group. Cardiovascular endurance and power was significantly higher in the exercise group than in the control group after 12-week exercise and the changes in cardiovascular endurance, power and percentage of body fat was significant. Cardiovascular endurance, flexibility and power showed interaction effects between the groups and times. Second, blood lipids indicated that TC, HDL-C, LDL-C significantly decreased in the exercise group. TC and LDL-C in the exercise group was significantly decreased compared to the control group after 12-week exercise. Finally, GH significantly increased within the exercise group and IGF-1 increased in the exercise group, but the difference was not statistically significant, respectively. Therefore, this research showed that trampoline exercise for 12 weeks had a positive PAPS, blood lipids, GH of overweight male middle school students.
