Intra-class correlation coefficients (ICC) and coefficients of variation (%CV) representing intra-subject reproducibility across three trials and two sessions. Data presented as mean ± SD. AP, arterial pressure (Systolic, Diastolic and Mean); HR, heart rate; SV, stroke volume; CO, cardiac output; TPR, total peripheral resistance.
