Basal values of arterial pressure and heart rate with respective low (LF) and high frequency (HF) components in trained (T) and sedentary (S) SHR and sedentary WKY groups at the different time-points.

<p>Values are means ± SEM; <i>n</i> is the number of rats in each subgroup. MAP, mean arterial pressure; SAP, systolic arterial pressure; HR, heart rate. Significances (<i>P<0.05</i>) are: *<i>vs</i> time-paired WKY,</p>†<p><i>vs</i> respective sedentary control,</p>‡<p><i>vs</i> week zero (T₀ or S₀).
