The advent of an ageing society has begun to become a big challenge for seeking for the way to prevent brain ageing and keeping brain fitness for the researchers, by which allows for a better understanding of the implications of specific lifestyle factors for cognitive health. We adopted cross-sectional analysis to explore the association between aerobic exercise and executive function is mediated by prefrontal cortex with multi model MRI technology among old Taichi practitioners. The hypothesis is that higher-fitness practitioners, better performance in task demanding executive control and multi-level changes such as greater grey matter volume, cortical thickness and more increased function connectivity of relevant network in prefrontal cortex.
