Abstract
We measured the brachial-ankle PWV (baPWV) after 60 watt exercising by bicycle ergometer for five minutes of 7 healthy young men (25 ± 4 years) and 7 middle-aged men (51 ± 4 years), and analyzed the changes in baPWV before and after the exercising. The resting baPWV before exercise was significantly higher in the middle-aged group compared to the young group (p<0.001). In both groups, baPWV after 6 minutes motor stress showed significantly lower values compared to resting baPWV (p<0.05). After 20 minutes exercising, baPWV declined 7 and 5 % in the young group and the middle-aged group, respectively. Heart rate (HR) increased by exercise recovered to normal levels in twelve minutes after exercise for both groups. From these results, by transient motor stress, it was seen that baPWV continued declining despite recovering HR after exercise, reconfirming exercise effects arterial dilatation.
