Effects of 10-week treadmill walking exercise training on cortical silent period (CSP) time. (A) In the hemisphere corresponding to the stronger hand, shorter CSP time (ms) at all transcranial magnetic stimulation intensities used [105–155% of active motor threshold (AMT)] suggested less GABAergic-mediated intracortical inhibition post-exercise training (ET), with return to baseline at 3-month follow-up (3-mo). (B) In the hemisphere corresponding to the weaker hand, although statistical significance was reached for the TMS intensities of 105, 115, and 125% of AMT between the different time points [Friedman's test: pre vs. post vs. 3-mo; χ²₍₂₎ = 6.33, p = 0.042], there was no statistical significance during pairwise analysis.
