Time to Move in Pregnancy Hyperglycemia

Completed · Not applicable

Conditions studied: GDM, Physical Activity, Hyperglycemia, Glucose Intolerance, Circadian Rhythm, Exercise

In brief

This randomized controlled crossover trial of 36 pregnant individuals with gestational diabetes (GDM) or gestational glucose intolerance (GGI) will: 1. Determine the effects of physical activity (PA) timing, specifically 30 minutes of moderate intensity walking or stepping in the morning (between 5am-9am, within 30-40 minutes of starting breakfast), versus late afternoon/evening (between 4pm-8pm, within 30-40 minutes of dinner) on glucose across the 24-hour cycle. 2. Explore the potential effects of the timing of PA on sleep and mood state.
