본 연구는 규칙적인 태권도 트레이닝이 비만 중년 여성의 뇌신경성장인자 및 인지기능에 미치는 영향을 알아보는데 목적이 있었다. 본 연구를 위하여 중년 비만 여성 33명이 연구대상자로 선정되었으 며, 연구대상자들은 태권도 그룹(TG, n=15)과 대조그룹(CG, n=18)에 무선 배정되었다. 태권도 그룹은 16 주간 일주일에 5번 태권도 트레이닝을 실시하였으며, 두 그룹 모두 트레이닝 전과 후 각각 brain-derived neurotrophic factor(BDNF), vascular endothelial growth factor(VEGF), insulin-like growth factor-1(IGF-1) 농도 검사와 Stroop Color and Word test를 실시하였다. 연구 결과 태권도 그룹의 BDNF와 IGF-1이 트레이닝 후 유의하게 증가한(p<.05) 반면 VEGF와 Stroop Color and Word Test 결과는 유의한 차이가 나타나지 않아 규칙적인 태권도 트레이닝이 비만 중년 여성의 뇌신경영양인자에는 긍정 적이지만 뇌 인지기능에는 영향이 없는 것으로 나타났다. The purpose of this study was to investigate the effects of regular taekwondo training on neurotrophic factors and cognitive function in obese middle-aged women. Thirty-three middle-aged women with obesity were selected for this study and randomly assigned into a control group(CG, n=18) and an taekwondo group(TG, n=15). The TG performed taekwondo training 5 times weekly for 16 weeks, while the CG did not exercise training. Serum brain-derived neurotrophic factor(BDNF), vascular endothelial growth factor(VEGF), and insulin-like growth factor-1(IGF-1) levels were analyzed and Stroop Color and Word tests were performed before and after the intervention. The serum BDNF and IGF-1 levels were significantly increased in the TG after the intervention(p<.05). On the other hand, no statistically significant differences were found in the serum VEGF levels, or in the Stroop Color and Word Test scores(p>.05). These results suggest that regular taekwondo training may be affects levels of peripheral neurotrophic factors but not cognitive function in obese middle-aged women.
