The purpose of this study was to analyze the effects of zero hour 8-shaped jump rope program for 12 weeks on PAPS(physical activity promotion system), BDNF(brain-derived neurotrophic factor) and learning attitude of elementary school students aged 12-13 years by dividing them into a control group(N = 15), exercise group(N = 20). This program included 30-minute sessions 3 times each week at the following intensities: 40–50% HRR for 1–4 weeks, 50–60% HRR for 5–8 weeks, 60–70% HRR for 9–12 weeks, and 60–70% HRR for 13–16 weeks. For the comparison of 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 an independent t-test was used to test differences between the control and exercise groups. And two-way repeated measures ANOVA was used to test the interactions between each period in the control and exercise groups. The alpha level of p<.05 was set for all tests of significance. The findings of this study were as follows; First, percentage of body fat significantly decreased and power, cardiovascular endurance, flexibility and learning attitude significantly increased in the exercise group. Second, the level of BDNF increased in the exercise group and decreased in the control group, but the difference was not statistically significant. Therefore, it is concluded that zero hour 8-shaped jump rope program for 12 weeks had a positive effect on PAPS(percentage of body fat, power, cardiovascular, flexibility) and learning attitude of elementary school students.

본 연구는 12주간의 8자줄넘기 프로그램이 초등학생의 PAPS, BDNF 및 학습태도에 미치는 영향을 구명하기 위하 여, Y초등학교 5-6학년 학생 35명을 대상으로 대조군(n=15), 운동군(n=20)으로 구분하여 실시하였다. 8자줄넘기 프로그램은 주 3회, 회당 30분으로 1-4주는 40-50%HRR, 5-8주는 50-60%HRR, 9-12주는 60-70%HRR의 강도 로 실시하였고, 측정된 자료의 그룹 내 차이는 paired t-test, 그룹 간 차이는 independent t-test를 실시하였으 며, 측정변인들에 대한 그룹 및 시기 간 상호작용을 검증하기 위해 two-way repeated measures ANOVA로 분 석하였다. 연구결과 PAPS(체지방률, 순발력, 심폐지구력, 유연성)와 학습태도에서 운동군 학생들이 대조군 학생들 보다 유의하게 더 향상되었다. BDNF는 운동군에서는 증가하였고, 대조군에서는 감소하였지만 통계적으로 유의한 차이는 나타나지 않았다. 결론적으로 12주간의 8자줄넘기 프로그램이 초등학생의 PAPS와 학습태도에 긍정적인 영 향을 주는 것으로 나타났다.
