- 研究成果概要
- Purpose: Although a single bout of continuous exercise (≥30 min) reduces postprandial triglyceride (TG), little evidence is available regarding the effect of short (≤10 min) bouts of exercise on postprandial TG in at-risk individuals. This study compared the effect of different patterns of walking on postprandial TG in older women with hypertriglyceridemia. Methods: Twelve older women (aged 71 ± 5 yrs, mean ± S.D.) with hypertriglyceridemia (fasting TG ≥ 1.70 mmol/L) completed three, one-day trials in a random order: 1) control, 2) continuous walking, and 3) short bouts of walking. On the control trial, participants rested for 8 hours. For the walking trials, participants walked briskly in either one 30-min bout in the morning (0900-0930) or twenty 90-sec bouts over 8 hours. Venous blood samples were collected in the fasted state and at 2, 4, 6 and 8 h after breakfast. Results: The serum TG incremental area under the curve was 35% and 33% lower on the continuous and short bouts of walking trials than the control trial (8.2 ± 3.1 vs 8.5 ± 5.4 vs 12.7 ± 5.8 mmol∙8h/L respectively, P = 0.001). Conclusions: Accumulating walking in short bouts limits postprandial TG in at-risk, older women with fasting hypertriglyceridemia.
