The general data were described by frequencies and percentages, and the quantitative data with normal distributions were represented by the representation. Repeated one‐way ANOVA was performed to assess the differences in the anaerobic power cycling test indicators (HRR and HRV) between groups before and during high‐intensity exercise. Repeated two‐way ANOVA was used to assess the differences in HRR and HRV between groups during the recovery period. The hypothesis testing criterion was set to
