본 연구의 목적은 뇌에 자극을 주고, 뇌를 깨워 활동할 수 있게 해주는 아침운동(점프밴드)을 12주간 실시하여 남자 중학생의 IGF-1, BDNF 및 cortisol에 미치는 영향을 구명하는데 있다. 13-15세 남자 중학생 24명을 대상으로 운동군 13명, 대조군 11명으로 구성하였고 운동군은 12주간 주 3회 45분간 수행하였다. 운동 강도는 4주 마다 점진적으로 증가시켰으며 여유 심박수 40-70%HRR로 설정하였다. 연구의 결과는 two-way repeated measures ANOVA, independent t-test, paired t-test를 사용하였고 유의수준은 α=.05로 설정하여 분석하였다. 그 결과 IGF-1(p<.01), BDNF(p<.001), cortisol (p<.01)에서 시기×그룹 간 상호작용 효과가 나타났으며, 본 연구의 결과에 따라 규칙적인 아침운동은 남자 중학생들의 IGF-1, BDNF 및 cortisol에 긍정적인 변화를 가져왔다.
The purpose of this study was to investigate the effect of morning exercise for 12 weeks on IGF-1 (insulin like growth factor-1; IGF-1), BDNF (brain-derived neurotrophic factor; BDNF) and cortisol in middle school male students aged 13 to 15 years old. The subjects were randomly assigned to an exercise group (n=13) and a control group (n=11). The 45 minute morning exercise routine (jump band exercise) was performed 3 times per week for 12 weeks. Exercise intensity progressively increased from 40% HRR to 70% HRR. The test data were analyzed by two-way repeated measures ANOVA, independent t-test, paired t-test and the alpha level of p<0.05 was set for all tests of significance. The findings of this study were as follows; IGF-1 and BDNF significantly increased and cortisol levels significantly decreased in the exercise group after participating in the morning exercise routine. In conclusion, this study suggests that regular and continuous jump band exercise is an effective method for improving brain function by increasing IGF-1 and BDNF levels and decreasing cortisol levels in male middle school students.
