To compare the impact of walking with a recreational activity on postprandial glycemia, heart rate variability, and mood state following the dinner meal.
Participants with type 2 diabetes (T2D) participated in 3 trials on different days in random order after ingestion of a standardized dinner meal (300 ± 6 kcals).
University clinical testing laboratory.
Twelve participants (9 female, 3 male; 58.7 ± 2.4 years) with uncomplicated T2D not taking insulin or beta-blocker medications.
Thirty minutes of self-paced walking on a treadmill (TM), 30 minutes of table tennis played continuously against the iPong robot (TT), and 30 minutes of rest (CON) undertaken 30 minutes after the start of ingestion of the same dinner meal on three occasions within a week.
Blood glucose was measured at 30-minute intervals through 180 minutes starting immediately prior to the dinner meal. Profile of Mood States was completed before and immediately following exercise or rest. Sympathovagal balance (heart rate variability) was measured prior to eating and 30 minutes after trial completion.
Compared with TT or CON, TM resulted in significantly lower postprandial blood glucose (P < .05), as well as a greater quantity of physical activity than TT (+72%) or rest (+91%; P < .01). Mean heart rate during TM was significantly greater than during TT (+25.9 beats per minute; P < .01). However, neither mood state nor HRV were significantly different among trials.
Thirty minutes of self-paced walking following the dinner meal may be more effective at lowering postprandial glycemia in T2D than a similar duration of table tennis played continuously against a robot.
比较餐后进行散步和娱乐性活动对餐后血糖、心率变异性和情绪状态的影响。
2 型糖尿病（T2D）患者在不同天内随机摄入标准化晚餐后进行 3 次试验。
大学临床测试实验室。
12 名参与者（9 名女性，3 名男性；58.7±2.4 岁）患有未经胰岛素或β受体阻滞剂治疗的单纯 T2D。
在跑步机（TM）上进行 30 分钟的自我 paced 散步，与 iPong 机器人连续打 30 分钟乒乓球（TT），以及在一周内的 3 次进餐 30 分钟后进行 30 分钟的休息（CON）。
从进餐前即刻开始，通过 180 分钟每隔 30 分钟测量一次血糖。在运动或休息前后完成心境状态问卷。在进食前和试验结束后 30 分钟测量自主神经平衡（心率变异性）。
与 TT 或 CON 相比，TM 导致餐后血糖显著降低（P<0.05），并且比 TT（+72%）或休息（+91%；P<0.01）的体力活动量更大。TM 期间的平均心率明显高于 TT（+25.9 次/分钟；P<0.01）。然而，在试验之间，心境状态或 HRV 均无显著差异。
与连续打乒乓球相比，餐后进行 30 分钟的自我 paced 散步可能更有效地降低 T2D 患者的餐后血糖。
