Values are mean ± standard deviation, SBP: systolic blood pressure, DBP: diastolic blood pressure, MAP: mean arterial pressure, SV: stroke volume, HR: heart rate, CO: cardiac output, TPR: total peripheral resistance. a: rest, b: recovery 10 min, c: recovery 20 min, d: recovery 30 min, e: recovery 40 min. a, b, c, d, e f: different alphabet appear significant difference stage. |
#p < .05, significant different between groups effects. |
*p < .05, significant different main or interaction effects. |
