Effects of short-term warm water immersion on cardiac baroreflex sensitivity in healthy men

Table 1 Tympanic temperature and systemic hemodynamics during sitting in the bathtub without (control) and with warm water (WWI)

Variables	Control	WWI	P-value
Tympanic temperature, °C	36.4 ± 0.3	36.4 ± 0.3	0.999
Heart rate, beats/min	62 ± 8	68 ± 8	0.017
Finger systolic BP, mmHg	107 ± 17	107 ± 17	0.961
Finger diastolic BP, mmHg	58 ± 14	62 ± 14	0.210
Finger MAP, mmHg	74 ± 15	77 ± 14	0.278
Stroke volume, mL	84.6 ± 17.2	83.5 ± 16.2	0.760
Cardiac output, L/min	5.2 ± 0.9	5.6 ± 1.2	0.022
Systemic VR, mmHg min/L	15.2 ± 6.3	14.6 ± 6.0	0.556

Data are mean and SD. Systemic hemodynamic variables were averaged values from 3.5 to 4.5 min of the sitting period
BP blood pressure, MAP mean arterial pressure, VR vascular resistance
