Postprandial exercise represents an important tool for improving the glycemic response to a meal. This study evaluates the effects of the combination and sequence of different exercise types on the postprandial glycemic response in patients with type 2 diabetes. In this repeated-measures crossover study, eight patients with type 2 diabetes performed five experimental conditions in a randomized order: (i) uninterrupted sitting (CON); (ii) 30 min of moderate intensity aerobic exercise (walking) (A); (iii) 30 min of combined aerobic and resistance exercise (AR); (iv) 30 min of combined resistance and aerobic exercise (RA); and (v) 15 min of resistance exercise (R). All the exercise sessions started 30 min after the beginning of a standardized breakfast. All the exercise conditions showed a significant attenuation of the post-meal glycemic excursion ( < 0.003) and the glucose incremental area under the curve at 0-120 min ( < 0.028) and 0-180 min ( < 0.048) compared with CON. A greater reduction in the glycemic peak was observed in A and AR compared to RA ( < 0.02). All the exercise types improved the post-meal glycemic response in patients with type 2 diabetes, with greater benefits when walking was performed alone or before resistance exercise.
餐后运动是改善餐后血糖反应的重要手段。本研究评估了不同运动类型的组合和顺序对 2 型糖尿病患者餐后血糖反应的影响。在这项重复测量交叉研究中，8 名 2 型糖尿病患者以随机顺序进行了五种实验条件：（i）不间断静坐（CON）；（ii）30 分钟中等强度有氧运动（步行）（A）；（iii）30 分钟有氧和抗阻运动的组合（AR）；（iv）30 分钟抗阻和有氧运动的组合（RA）；以及（v）15 分钟抗阻运动（R）。所有运动均在标准化早餐开始后 30 分钟开始。与 CON 相比，所有运动条件均显著降低餐后血糖波动（ < 0.003）和 0-120 分钟（ < 0.028）和 0-180 分钟（ < 0.048）的血糖增量曲线下面积。与 RA 相比，A 和 AR 中的血糖峰值降低幅度更大（ < 0.02）。所有运动类型均改善了 2 型糖尿病患者的餐后血糖反应，单独进行或在抗阻运动之前进行步行时获益更大。
