关于降低餐后血糖（PPG）的最佳运动时间尚未达成共识。本研究的目的是确定最有效的锻炼时间。十一名参与者完成了四种不同的锻炼模式：1）不锻炼； 2）餐前运动（慢跑）； 3）餐后运动； 4) 短暂的定期运动干预（三组 1 分钟慢跑 + 30 秒休息，每 30 分钟一次，共 20 次），随机顺序，间隔至少 5 天。餐前和餐后运动包括20组间歇运动（每组1分钟慢跑+30秒休息），每天重复3次。所有三种运动模式的每日总运动量都是相同的。运动强度为 62.4 +/- 12.9% V-O2peak。每次试验期间连续测量血糖浓度 24 小时。早餐后，短暂定期运动的峰值血糖浓度 (99 +/- 6 mg/dl) 低于餐前和餐后运动的峰值血糖浓度 (分别为 109 +/- 10 和 115 +/- 14 mg/dl，P < 0.05，效应大小 = 0.517)。午餐后，短暂定期运动的血糖峰值浓度低于餐后运动的血糖浓度（97 +/- 5 和 108 +/- 8 mg/dl，P < 0.05，效应大小 +/- 0.484）。晚餐后，不同运动模式的血糖峰值浓度没有显着差异。餐后 24 小时和餐后 2 小时的曲线下面积在运动模式之间没有差异。这些研究结果表明，在年轻活跃个体中，短暂的定期运动可能比餐前和餐后运动更有效地减弱 PPG。 新的和值得注意的 这是第一项研究不同运动时间（短暂的定期运动、餐前运动和餐后运动）对活跃的健康男性餐后血糖 (PPG) 减弱的影响。我们证明，短暂的定期运动比餐前和餐后运动更能降低 PPG 峰值水平，尤其是在早上。此外，餐后运动停止后，PPG 很快就会反弹。因此，在降低 PPG 水平方面，短暂的定期锻炼可能比餐前和餐后锻炼更好。
There is no consensus regarding optimal exercise timing for reducing postprandial glucose (PPG). The purpose of the present study was to determine the most effective exercise timing. Eleven participants completed four different exercise patterns 1) no exercise; 2) preprandial exercise (jogging); 3) postprandial exercise; and 4) brief periodic exercise intervention (three sets of 1-min jogging + 30 s of rest, every 30 min, 20 times total) in a random order separated by a minimum of 5 days. Preprandial and postprandial exercise consisted of 20 sets of intermittent exercise (1 min of jogging + 30 s rest per set) repeated 3 times per day. Total daily exercise volume was identical for all three exercise patterns. Exercise intensities were 62.4 +/- 12.9% V-O2peak. Blood glucose concentrations were measured continuously throughout each trial for 24 h. After breakfast, peak blood glucose concentrations were lower with brief periodic exercise (99 +/- 6 mg/dl) than those with preprandial and postprandial exercise (109 +/- 10 and 115 +/- 14 mg/dl, respectively, P < 0.05, effect size = 0.517). After lunch, peak glucose concentrations were lower with brief periodic exercise than those with postprandial exercise (97 +/- 5 and 108 +/- 8 mg/dl, P < 0.05, effect size +/- 0.484). After dinner, peak glucose concentrations did not significantly differ among exercise patterns. Areas under the curve over 24 h and 2 h postprandially did not differ among exercise patterns. These findings suggest that brief periodic exercise may be more effective than preprandial and postprandial exercise at attenuating PPG in young active individuals.NEW & NOTEWORTHY This was the first study to investigate the effect of different exercise timing (brief periodic vs. preprandial vs. postprandial exercise) on postprandial glucose (PPG) attenuation in active healthy men. We demonstrated that brief periodic exercise attenuated peak PPG levels more than preprandial and postprandial exercise, particularly in the morning. Additionally, PPG rebounded soon after discontinuing postprandial exercise. Thus, brief periodic exercise may be better than preprandial and postprandial exercise at attenuating PPG levels.
