• EFFECTS OF 12 WEEKS OF PHYSICAL TRAINING ON CARDIOVASCULAR RESPONSES TO HEAD-UP TILT DURING HEAT EXPOSURE IN SEDENTARY MEN

抄録

The purpose of this study was to investigate the effects of 12weeks of physical training on cardiovascular responses to postural change at 27℃ and 35℃. 16 sedentary subjects were assigned to either a training group (n=8:30-min ergometer at 60% V^^・O_2peak, 3 days a week) or a control group (n=8 : no exercise). Measurements were made of heart rate (HR), stroke volume (SV), cardiac index (CI), mean blood pressure (MBP), total peripheral resistance (TPR), rectal temperature (Tr), mean skin temperature (Tsk) and heart rate variability (HRV), before and after a chronic physical training. After training, training group significantly increased their V^^・O_2 peak (+10.3%, p<0.01). As for the cardiovascular responses to head-up tilt, in both group there were significant interaction effects between postural condition and ambient temperature in HR, CI and TPR. In training group, HR was significantly decreased after training during head-up tilt at 27℃. These results suggest that the physical training may effect on cardiovascular responses to postural change.
