Experimental timeline.
No full text<p>Measures of resting motor threshold (RMT), active motor threshold (AMT), motor evoked potential (MEP) recruitment curves obtained at rest (MEP<sub>REST</sub>) and during ~10% MVC (MEP<sub>ACTIVE</sub>), short-interval intracortical inhibition (SICI), intracortical facilitation (ICF) and short-interval intracortical facilitation (SICF) were acquired prior to (T<sub>0</sub>) and ten minutes following the cessation of exercise (T<sub>1</sub>).The order of dependent measure acquisition was pseudo-randomized across participants using a Williams Square design. The exercise intervention began following the assembly of the heart rate (HR) monitor and involved 5 minutes of cycling warm-up, 20 minutes of moderate-intensity exercise (50–70% of age-predicted maximal heart rate (HR)) and 5 minutes of cycling cool-down. During the 20-minute exercise, resistance was adjusted online to maintain HR in the target range. HR was recorded every 2 minutes as shown.</p
Thresholds and recruitment curves.
No full text<p><b>(A)</b> Group-averaged MEP<sub>REST</sub> recruitment curves (with standard errors) at T<sub>0</sub> and T<sub>1</sub> for the LOW (N = 14) and HIGH (N = 13) groups. TMS intensity is defined as the percentage of RMT. Solid and dashed lines indicate pre (T<sub>0</sub>) and post (T<sub>1</sub>) values, respectively. <b>(B)</b> Histograms displaying TIME x GROUP interaction for group-averaged MEP<sub>REST</sub> amplitude (with standard error; LOW: N = 14, HIGH: N = 13). The asterisk indicates a significant increase in MEP<sub>REST</sub> amplitudes. <b>(C)</b> Histograms displaying TIME x GROUP interaction for group-averaged MEP<sub>REST</sub> AURC (with standard error; LOW: N = 14, HIGH: N = 14). The asterisk indicates a significant increase in MEP<sub>REST</sub> AURC. <b>(D)</b> Group-averaged MEP<sub>ACTIVE</sub> recruitment curves (with standard errors) at T<sub>0</sub> and T<sub>1</sub> for the LOW (N = 14) and HIGH (N = 13) group. TMS intensity is defined as the percentage of the active motor threshold (AMT). Solid and dashed lines indicate pre (T<sub>0</sub>) and post (T<sub>1</sub>) values, respectively.</p
