Effects of supervised exercise during pregnancy on gestational diabetes mellitus and other pregnancy outcomes: a systematic review and meta-analysis

The authors aimed to evaluate the effects of supervised exercise on gestational diabetes mellitus (GDM) and various pregnancy outcomes through a systematic review and meta-analysis. They found that supervised exercise significantly reduced the risk of GDM, gestational hypertension, excessive weight gain, and macrosomia, particularly when initiated early in pregnancy, adhered to closely, and included a combination of aerobic and resistance training. The study highlights the importance of exercise dosage, with optimal benefits observed at around 500-550 metabolic equivalent task-minutes per week.
