청소년기의 신체활동정도에 따른 체력 및 혈중 BDNF 발현이 인지능력향상에 미치는 효과

Abstract

The purpose of the present research is to investigate the effects of Physical activity levels onserum levels of neurotrophins and neurocognitive function. The subjects of the research were 60 healthy maleadolescents. The subjects underwent three experiments according to physical activity level: one experiment inthe Elit Athletes (EA, N=20) condition, Physical exercise (PS, N=20) condition, and the other in the ControlGroup (CG, N=20) condition. Blood samples were collected analyses of serum brain-derived neurotrophic factor(BDNF) and insulin-like growth factor-1 (IGF-1). For the measurements of neurocognitive functions, the StroopColor-Word test and Physical activity-related energy expenditure, Caloric intake of Lifestyle habit. The resultsof the research showed that the serum levels of the BDNF, IGF-1 and Stroop Color-Word test weresignificantly differences a between groups(p<0.05), and BDNF of Post-hoc for significantly higher in PS thanCG (p<0.05), IGF-1 of Post-hoc for significantly higher in PS, EA than CG (p<0.001). Color-Word score ofPost-hoc for significantly higher in EA than CG, PE (p<0.001). In the VO2max, PAEE and Caloric intake ofLifestyle habit significantly differences scores were observed a between groups(p<0.001, p<0.001, p<0.05). Withrespect to the serum levels of the neurotrophic factor (BDNF, IGF-1) and neurocognitive functions(StroopColor-Word test) a positive correlation between physical activity level. In addition, these results suggest thatlong-term regular physical activity has positive effects on neurocognitive functions and neurotrophins factor.
