  1. All data are presented as mean ± standard deviation. The paired t test was used to compare differences between ERP peaks’ amplitudes and latencies at rest and while cycling and differences between the mean amplitude of late slow wave (LSW) at rest and while cycling. The bold p value indicates significant variables after conducting Hochberg’s correction on each component
