Abstract

Exercise can favorably influence brain plasticity by facilitating neurogeneration, neuroadaptivity, and neuroprotection. Aerobic exercise has been reported to change brain nerve growth factors (growth hormone, insulin like factor-1, estrogen and serotonin). The purpose of this study was to demonstrate the effects of aerobic exercise for 12 weeks on brain nerve growth factors in girls. Fourteen female participants in elementary school grades 1 through 3 were randomly allocated to the exercise group (EG, n=6) and control group (CG, n=8). The EG participated in 60 minutes of modified ballet exercise as aerobic training three days a week for 12 weeks. Based on comparison between groups by two-way ANOVA with repeated measures, aerobic exercise program participants experienced decreased weight (p<0.01), BMI (p<0.01), fat mass (p<0.001), fat percent (p<0.001) and increased LBM (lean body mass) percent (p<0.001). In addition, we detected that aerobic exercise decreased the level of serotonin (p<0.05) and increased the level of GH (p<0.05) and IGF-1 (p<0.05). These findings suggest that aerobic exercise programs can be an efficient intervention to change body composition, alleviate central fatigue, improve brain function, and induce brain cell proliferation in girls.

운동은 신경의 생성, 적응, 보호 기능을 통해 뇌 기능 및 생성에 긍정적인 영향을 미치며, 유산소운동은 뇌신경 성장인자(GH, IGF-1, estrogen, serotonin)를 변화시키는 것으로 보고되었다. 본 연구는 여자 아동의 뇌기능 발달 및 뇌세포 생성 유도인자의 유산소운동 효과를 알아보고자 유산소운동 프로그램에 따른 뇌신경 성장인자(GH, IGF-1, estrogen, serotonin)의 변화를 분석하여 다음과 같은 결론을 얻었다. 반복측정 분산분석에 의해 운동군과 대조군의 평균을 비교한 결과 유산소운동은 집단간 유의한 차이를 보이며 체중, BMI, 체지방량, 체지방률을 감소 시켰으며, 제지방률을 증가시켰다. 또한 뇌신경 성장인자인 serotonin을 감소시켰으며, GH와 IGF-1을 증가시켰다. 본 연구결과 유산소운동 프로그램이 아동의 체중, BMI, 체지방, 체지방률 감소와 제지방률 증가에 효과적이다. 또한 serotonin이 운동 후 감소된 결과를 볼 때 유산소운동 프로그램이 아동의 중추피로 감소에 효과적이며, GH, IGF-1의 운동 후 증가된 결과를 볼 때 유산소운동이 아동의 뇌기능 발달 및 뇌세포 생성 유도에 긍정적인 프로그램임을 알 수 있다.
