PURPOSE: To assess the effectiveness of a maternal exercise program (land/aquatic activities; both aerobic and muscular conditioning) in preventing gestational diabetes mellitus (GDM). METHODS: Two hundred and seventy-two pregnant women from Spain (age 33.24 +/- 4.3 years) without obstetric contraindications were recruited for a clinical randomized controlled trial. The intervention group (IG; n = 101) exercised for 60 minutes and 50 minutes on land and in water, respectively, 3 times per week. The control group (CG; n = 156) received usual standard care. RESULTS: The prevalence of GDM was reduced in the IG group (IG 1%, n = 1 versus CG 8.8%, n = 13 (Chi2 = 6.84; p = 0.009)) with a significant risk estimate (OR 0.103; 95% CI 0.013 to 0.803). CONCLUSION: The exercise program performed during pregnancy reduced the prevalence of GDM by preserving glucose tolerance.
