Abstract

Aim/introduction: This study investigated if immediately post-lunch exercise may improve postprandial hyperglycemia in individuals with prediabetes.

Materials and methods: The study consisted of a control phase involving no exercise and an exercise phase involving exercise. During both phases, participants were assessed for their AUC, RCMC and %TITR using CGM-derived postprandial data; they were also assessed for physical activity using a physical activity tracker and for energy intake using a dietary management application.

Results: Of the 43 males included, 23 were available for analysis. Their AUC values were significantly lower at post-lunch 1 h in the exercise phase than in the control phase with their %TITR values being significantly higher in the exercise phase than in the control phase. Their cumulative AUC values were significantly lower for post-lunch 2, 3, and 4 h in the exercise phase, with the cumulative %TITR values being also significantly higher. Their RCMC values were significantly lower for post-lunch 0-1 and 3-4 h, and significantly higher for post-lunch 1-2 h, in the exercise phase than in the control phase, with no difference for post-lunch 2-3 h between the phases. They exhibited monophasic or biphasic glucose profiles in the exercise phase with significantly different AUC and %TITR values for post-lunch 0-4 h, but no difference in HR reserve (HRR), energy intake or its composition.

Conclusion: In those with prediabetes, postprandial hyperglycemia improved with immediately post-lunch exercise, with significant improvements in cumulative AUC and %TITR values. Further study is required to clarify why they exhibited disparate glucose profiles.

改善糖尿病前期、久坐上班族午餐后立即进行中等强度运动的餐后高血糖:使用身体活动追踪器、饮食管理应用程序和连续血糖监测的综合评估
目的/介绍:本研究调查了是否午饭后立即运动可以改善糖尿病前期患者的餐后高血糖。材料和方法:研究分为不运动的控制阶段和运动阶段。在这两个阶段,使用cgm衍生的餐后数据评估参与者的AUC、RCMC和%TITR;研究人员还使用身体活动追踪器对他们进行了身体活动评估,并使用饮食管理应用程序对他们的能量摄入进行了评估。结果:纳入的43名男性中,有23名可供分析。午休后1 h,运动阶段的AUC值显著低于对照组,运动阶段的%TITR值显著高于对照组。午休后2、3、4 h的累计AUC值显著低于午休后2、3、4 h,累计%TITR值显著高于午休后2、3、4 h的累计AUC值。运动阶段的RCMC值在午餐后0-1和3-4 h显著低于对照组,在午餐后1-2 h显著高于对照组,在午餐后2-3 h无显著差异。他们在运动阶段表现出单相或双相葡萄糖谱,午餐后0-4小时的AUC和%TITR值有显著差异,但HR储备(HRR)、能量摄入或其组成没有差异。结论:在糖尿病前期患者中,餐后高血糖通过午餐后立即运动得到改善,累积AUC和%TITR值有显著改善。需要进一步的研究来阐明为什么他们表现出不同的葡萄糖谱。

期刊介绍: Diabetology International, the official journal of the Japan Diabetes Society, publishes original research articles about experimental research and clinical studies in diabetes and related areas. The journal also presents editorials, reviews, commentaries, reports of expert committees, and case reports on any aspect of diabetes. Diabetology International welcomes submissions from researchers, clinicians, and health professionals throughout the world who are interested in research, treatment, and care of patients with diabetes. All manuscripts are peer-reviewed to assure that high-quality information in the field of diabetes is made available to readers. Manuscripts are reviewed with due respect for the author''s confidentiality. At the same time, reviewers also have rights to confidentiality, which are respected by the editors. The journal follows a single-blind review procedure, where the reviewers are aware of the names and affiliations of the authors, but the reviewer reports provided to authors are anonymous. Single-blind peer review is the traditional model of peer review that many reviewers are comfortable with, and it facilitates a dispassionate critique of a manuscript.
