SAP, Systolic arterial pressure; PI, pulse interval; LF, low-frequency component; HF, high-frequency component; αLF and αHF, spontaneous baroreflex sensitivity estimated by LF and HF spectral components respectively. Correlations include 24–30 values of sedentary and trained rats (n = 4 rats/subgroup) from all time points.
#
denotes a significant correlation after Bonferroni correction of the significant level (αc = 0.0028) for the 18 analysis made.
