Introduction: Gestational Diabetes is a group of metabolic disorders that result in glucose intolerance during pregnancy. Among the range of treatments are diet, continuous use of medication, and psychological monitoring. Since it is a multidisciplinary treatment, a proper protocol is vital for a favorable outcome. In addition, there are questions about the benefits of physical activity as a complementary therapy. Objective: To verify the impact of adding exercise to the hospital protocol for patients with gestational diabetes, both on the risks of type 2 diabetes in pregnant women and on the obesity of their offspring. Methods: Sixty pregnant women diagnosed with Gestational Diabetes were randomly divided into control and intervention groups. Both groups received specific treatment and intervention, and the experimental group practiced controlled moderate-intensity physical activity (125-146bpm). Morning blood samples were collected from both groups to check fasting glucose and insulin levels, indicators of lipid metabolism, low and high-density lipoprotein cholesterol, apolipoprotein B. The Brog scale measured the fatigue level. In addition, the premature rupture of membranes, postpartum hemorrhage, neonatal asphyxia, macrosomia, and others was checked. Results: The peripheral blood total cholesterol levels were 5.93, 5. 38, low-density lipoprotein cholesterol levels were 2.95 before versus 2.64 after, and apolipoprotein B levels were 1.84 versus 1.59 in the control group, high-density lipoprotein cholesterol content increased from 1.74 to 1.88, blood cholesterol, and apolipoprotein B levels after the intervention in the experimental group were lower than those in the control group, with an elevation of high-density lipoprotein cholesterol. Conclusion: Aerobic exercise proved to be more appropriate for patients with gestational diabetes in the later stages of pregnancy and may also be adapted for bedridden patients refractory to traditional drugs.
