Exercise-mediated, brain-derived neurotrophic factor induction benefits health and cognitive functions. The multifaceted interplay between physical activity, urinary brain-derived neurotrophic factor levels and cognitive functioning has been largely neglected in previous literature. In this pilot study, two bouts of training exercise (65% and 70% of heart rate reserve) influenced urinary brain-derived neurotrophic factor levels and cognitive performances in 12 overweight and obese participants. Percent heart rate reserve, expenditure energy, brain-derived neurotrophic factor urinary levels and cognitive performances were measured before and after the exercise. No significant variations in energy expenditure were observed, while differences of heart rate reserve between two groups were maintained. Both bouts of training exercise induced a similar reduction in urinary brain-derived neurotrophic factor levels. Only visuo-spatial working memory capacity at 65% of heart rate reserve showed a significant increase. These findings indicate a consistent effect of training exercise on urinary brain-derived neurotrophic factor levels and cognitive factors in overweight and obese participants.
运动介导的脑源性神经营养因子诱导有益于健康和认知功能。以往文献在很大程度上忽视了身体活动、尿脑源性神经营养因子水平和认知功能之间的多方面相互作用。在这项初步研究中，两次训练运动（心率储备的65%和70%）影响了12名超重和肥胖参与者的尿脑源性神经营养因子水平和认知表现。在运动前后测量心率储备百分比、能量消耗、尿脑源性神经营养因子水平和认知表现。未观察到能量消耗有显著变化，而两组之间的心率储备差异保持不变。两次训练运动均导致尿脑源性神经营养因子水平出现类似程度的降低。仅在心率储备为65%时视觉空间工作记忆能力有显著提高。这些发现表明训练运动对超重和肥胖参与者的尿脑源性神经营养因子水平和认知因素具有一致的影响。
