研究成果概要
This study was to examine the chronic effect of increased physical activity of daily living on postprandial triacylglycerol (TAG) in postmenopausal women. Twentysix postmenopausal women, aged 72 ± 5 years (mean ± SD), were randomly divided into two groups: active (n=11) and control (n=15) groups. The participants in the active group were asked to increase their activities above their usual lifestyle levels  for 3 months; freely deciding the duration and intensity of their chosen activities (i.e., at least 10 minutes per day). The participants in the control group maintained their usual lifestyle for 3 months. All participants were asked to wear a uniaxial accelerometer for 3 consecutive months. At baseline, after 1 month and after 3 months, all participants rested and consumed a standardised breakfast after a 24-hour period of physical activity avoidance. Blood samples were collected in the fasted state (0 hour) and at 2, 4 and 6 hours after breakfast. There was no difference in the pattern of postprandial TAG response between groups. Postprandial TAG was not reduced after performing self-selected activities under free-living in postmenopausal women when these responses are determined 24 hours after the last physical activity bout.
