Summary

This trial will study the effects of different times of physical activity on glucose levels in pregnant people with gestational diabetes or gestational glucose intolerance. It will also investigate if the timing of physical activity affects sleep

Who is the study for?

This trial is for pregnant individuals aged 18-40 with gestational diabetes or glucose intolerance, carrying a single baby without significant abnormalities. Participants must have been diagnosed after 24 weeks of pregnancy and be comfortable communicating in English without a translator.

What is being tested?

The study tests the effects of timing on physical activity—specifically, whether walking or stepping for 30 minutes in the morning versus late afternoon/evening has different impacts on blood sugar levels, sleep quality, and mood during pregnancy.

What are the potential side effects?

Since the intervention involves moderate intensity walking or stepping, potential side effects may include typical exercise-related discomforts such as muscle soreness or fatigue but are generally minimal.
