- 研究成果概要
- This study aimed to investigate the effects of a single bout of upper or lower body exercise on postprandial triglyceride (TG) concentrations in healthy young men. Nine healthy young men (aged 22 ± 2, body mass index 22 ± 2, mean ± SD ) underwent three, 8-h experimental trials with at least a 7-day washout period: 1) control (C), 2) upper-body exercise (U) and 3) lower-body exercise (L). On the C trial, participants sat in a chair for 8 h. For the exercise trials, participants performed one 30-min bout of upper-body or lower-body exercise in the morning (0900-0930 h). Except for exercise, both exercise trials mimicked the control trial. In each trial, participants consumed a standardised breakfast (1000 h) and lunch (1300 h). Blood samples were collected in the fasted state, immediately after exercise or rest (0.5 h), and at 2, 4, 6, and 8 h after the commencement of each trial. Serum TG concentrations differed among trials and were higher in the U trial than L and C trials. The present study demonstrates that an acute bout of upper-body exercise increases postprandial TG concentrations, partly due to a transient insulin resistance by the physiological stress of unfamiliar exercise.
