  1. Δα and Δβ are the change rates in the alpha-band power (α) and beta-band power (β) between pedal stages. For example, Δα from early to middle stages is defined as (αmiddle - αearly) / αearly. The change rate is represented as median (interquartile range). The paired permutation test is used to compare the distributions of change rates between low- and high-resistance exercises, where the mark * indicates a significance level of p < 0.05. The effect size is reported as the correlation coefficient ρ based on the Wilcoxon signed-rank test
