- 研究成果概要
- Purpose: The present study examined the effect of multiple short bouts of exercise, with and without dietary replacement of the exercise-induced energy deficit, on postprandial TG in older women. Methods: Seventeen postmenopausal women underwent three, 8-hour laboratory-based trials in a random order: 1) control, 2) accumulated walking and 3) accumulated walking with energy replacement. During the control trial, participants rested for 8 hours. The accumulated walking trial comprised twenty 1.5 min bouts of brisk walking performed at a pre-determined self-selected pace with 15 min seated rest between walks. In each trial, participants consumed a standardised breakfast (0800, 0 h) and lunch (1100, 3 h). The breakfast in the accumulated walking with energy replacement trial included replacement of the same energy deficit induced by exercise. Venous blood samples were collected fasted and at 2, 4, 6 and 8 h after breakfast. Results: Time-averaged postprandial serum TG concentrations over 8 hours were lower after accumulated walking than control and accumulated walking with energy replacement. There was little difference between control and accumulated walking with energy replacement. Conclusions: Replacing the energy expenditure induced by accumulating 30 min of brisk walking in short (1.5 min) bouts diminishes the postprandial TG-lowering effect in postmenopausal women.
