Supporting data: Ageing attenuates exercise-enhanced motor cortical plasticity

In this study, we compared the effects of a single session of cardiorespiratory exercise on motor cortical plasticity in young and older adults. We acquired measures of cortical excitatory and inhibitory activity of the primary motor cortex using transcranial magnetic stimulation (TMS) from 20 young and 20 older healthy adults. Single and paired pulse TMS measures were collected before and after a 20-minute bout of high-intensity interval cycling exercise or an equivalent period of rest, and again after intermittent theta burst stimulation (iTBS).

本研究旨在对比单次心肺运动对青年及老年人运动皮层可塑性的影响。我们采用经颅磁刺激（TMS）技术，对20名青年和20名老年人初级运动皮层的皮层兴奋性和抑制性活动进行了测量。在20分钟高强度间歇性骑自行车运动或相应休息期间前后，以及再次经过间歇性θ波爆发刺激（iTBS）后，收集了单脉冲和成对脉冲TMS的测量数据。
