초록
본 연구의 목적은 규칙적으로 훈련을 실시하고 있는 투기종목 선수들과 일반인을 구분하여, BDNF의 차이를 분석하고, 심폐체력 및 근 기능과의 관련성을 알아보고자 한다. 연구의 대상은 Y 대학교 무도대학에 재학 중인 투기선수들 중 용무도 10명, 유도 10명, 레슬링 10명 및 일반학생 10명을 포함한 총 40명으로 표집 하였다. BDNF와 비만요인, 심폐체력 및 근 기능과의 관련성을 규명하기 위해, 점증부하운동방법을 이용하여 최대산소섭취량을 측정하고, 등속성 근기능 장비를 이용하여 각속도별에 따른 신근과 굴근을 측정하였다. 본 연구의 결과는 첫째, 무도종목선수들과 일반인의 뇌건강지표(BDNF)의 차이는 나타나지 않았다. 둘째, 심폐운동능력은 유도와 용무도집단, 일반집단과 모든 투기종목 집단간 통계적으로 유의한 차이를 나타내었다(p<.001). 셋째, 등속성 근기능 결과는 용무도와 레슬링 집단간에 근파워와 근지구력에서 통계적으로 유의한 차이를 나타내었다(p<.05). 넷째, 투기종목 선수들의 뇌 건강지표 BDNF와 심폐운동능력, 체지방률, 근파워 및 근지구력에서 통계적으로 정적인 관련성을 나타내었다(p<.05). 이러한 결과를 종합해 볼 때, 투기종목 선수들의 안정시 BDNF 발현량은 장기간 유산소성 운동 수행과의 관련성을 설명하고 있으며, 운동선수들의 뇌건강 지표를 개선시키기 위한 방법으로 규칙적인 유산소 운동을 통한 비만요인 개선, 심폐운동능력, 근 파워 및 근 지구력 향상이 필요하다고 생각된다.
Abstract
The purpose of this study is to provide a data for predicting brain health and developing them through analysis which are difference BDNF between martial art athletes and normal group and correlation of health factor, cardiorespiratory, muscle function with BDNF. Subjects were participated by Yongmoodo, Judo, Wrestling athletes and Normal group each ten person. We tested maximal oxygen uptake using graded exercise test to investigate a correlation on BDNF, obesity, cardiorespiratory and muscle function. Also, subject were tested eccentric and concentric muscle using ISOMED 2000. Results as follow:First, there was no statistically significant difference on BDNF between martial art athletes and normal group. Second, there was statistically significant difference on cardiorespiratory between Yongmoodo and Judo as well Normal group. Third, there was statistically significant difference on muscle function(muscle power & endurance) between Yongmoodo and Wrestling as well Normal group. Fourth, there was statistically significant positive correlation on cardiorespiratory, %bodyfat, muscle power & endurance with blood BDNF. These results are meaning that BDNF creation is related with long term aerobic exercise. Further more, they need improvement of obesity, cardiorespiratory and muscle functions from regular aerobic exercise to develop brain health.
