■探索体力活动(PA)之间关系的研究有限,认知功能,以及健康老年人的大脑加工特征。
■总共41名参与者(42.7±20.5年,56.1%的男性)被纳入数据分析。国际身体活动问卷简表用于评估PA水平,并采用中文版《蒙特利尔认知评估基础》和《Flanker任务》评估认知功能。此外,fMRI技术用于检查大脑激活模式。
■发现老年人的认知功能明显低于年轻人。在老年人中,PA水平高的患者的认知功能明显高于PA水平低和中的患者。fMRI数据显示,不同PA水平的年轻人之间的大脑激活模式存在显着差异。然而,在老年人中没有观察到这种差异.
■在老年人中观察到认知功能下降。健康老年人的PA水平与认知功能之间存在显着相关性。该研究表明,PA水平对年轻人抑制控制相关区域的大脑激活模式有显著影响。虽然在老年人中并不重要。研究结果表明,驱动PA和认知功能之间关系的神经机制可能在老年人和年轻人之间有所不同。
UNASSIGNED: There are limited studies exploring the relationship between physical activity (PA), cognitive function, and the brain processing characteristics in healthy older adults.
UNASSIGNED: A total of 41 participants (42.7 ± 20.5 years, 56.1% males) were included in the data analysis. The International Physical Activity Questionnaire Short Form was used to assess PA levels, and the Chinese version of the Montreal Cognitive Assessment-Basic and the Flanker task were employed to evaluate cognitive function. Furthermore, fMRI technology was utilized to examine brain activation patterns.
UNASSIGNED: The cognitive function of the older adults was found to be significantly lower compared to the young adults. Within the older adults, those with high levels of PA exhibited significantly higher cognitive function than those with low and medium PA levels. The fMRI data showed significant differences in brain activation patterns among young adults across the different PA levels. However, such difference was not observed among older adults.
UNASSIGNED: A decline in cognitive function was observed among older adults. There was a significant correlation between the levels of PA and cognitive function in healthy older adults. The study demonstrated significant effects of PA levels on brain activation patterns in inhibitory control-related regions among young adults, while not significant among older adults. The findings suggest that neurological mechanisms driving the relationship between PA and cognitive function may differ between older and young adults.
