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

Table 2 Hemodynamic response to the stand-up challenge without (control) and with warm water (WWI)

Variables	Control	WWI	P-value
Baseline HR, beat/min	62 ± 7	72 ± 9	0.003
Baseline MAP, mmHg	73 ± 16	77 ± 16	0.322
Nadir MAP, mmHg	43 ± 8	46 ± 12	0.364
Delta MAP, mmHg	− 33 ± 11	− 34 ± 14	0.700
Beat to nadir MAP, beats	13 ± 2	11 ± 4	0.235
Number of data plots, n	6.3 ± 1.5	4.8 ± 1.3	0.007
Correlation coefficient	0.964 ± 0.022	0.968 ± 0.027	0.719

Data are mean and SD. Baseline data were averaged values for 10 s immediately before the stand-up motion. HR heart rate, MAP finger artery mean arterial pressure. Number of data plot and correlation coefficient were obtained from the regression line calculation data between finger systolic blood pressure and R–R interval
