Optimizing Blood Glucose Control through the Timing of Exercise in Pregnant Individuals Diagnosed with Gestational Diabetes Mellitus.
Study Goal
The researchers aimed to evaluate the effectiveness of moderate-intensity walking on postprandial blood glucose control in pregnant individuals with and without gestational diabetes mellitus (GDM).
Results Summary
The study found that the GDM group had higher fasting, 24-h mean, and daily peak glucose values compared to the NON-GDM group across all conditions. Participants completed different walking protocols (short vs. long duration) and indicated their preference via a physical activity enjoyment scale (PACES).
Population
Pregnant individuals with (GDM) and without gestational diabetes mellitus (NON-GDM).
Effective Dosage
Three 10-minute walks immediately after eating (SHORT) or one 30-minute walk outside of 1 hour after eating (LONG).
Duration
5 days of exercise protocols, preceded and separated by 2 days of habitual exercise (total 14-day monitoring period).
Interactions
None mentioned

This study aimed to evaluate the effectiveness of moderate intensity walking on postprandial blood glucose control for pregnant individuals with (GDM) and without gestational diabetes mellitus (NON-GDM). Using a randomized cross-over design, individuals completed 5 days of exercise (three 10-min walks immediately after eating (SHORT), or one 30-min walk (LONG) outside of 1 h after eating). These protocols were preceded and separated by 2-days of habitual exercise (NORMAL). Individuals were instrumented with a continuous glucose monitor, a physical activity monitor for 14-days, and a heart rate monitor during exercise. Participants completed a physical activity enjoyment scale (PACES) to indicate their protocol preference. The GDM group had higher fasting, 24-h mean, and daily peak glucose values compared to NON-GDMs across all conditions (effect of group,
