Supervised and Unsupervised Physical Activity Programs in Pregnancy-There Is a Benefit for Both.

Area of Science:

• Obstetrics and Gynecology
• Sports Medicine
• Public Health

Background:

• Regular physical activity (PA) during pregnancy is crucial for reducing cardiometabolic disease risk.
• The World Health Organization recommends 150 minutes of moderate-intensity exercise weekly, but adherence is low.
• Understanding the impact of different exercise program structures on pregnancy outcomes is essential.

Purpose of the Study:

• To compare the effects of supervised versus unsupervised exercise programs on gestational weight gain and birth outcomes.
• To identify predictors of infant morphometrics in pregnant women undertaking exercise programs.

Main Methods:

• A study involving 478 pregnancies across two countries.
• Participants were assigned to either a supervised or unsupervised exercise program.
• Maternal characteristics, PA levels, and birth outcomes were analyzed.

Main Results:

• Significant differences in gestational weight gain were observed between groups (p = 0.007).
• The supervised group showed a substantial increase in weight gain (21.99 ± 36.34) versus the unsupervised group (14.22 ± 10.91).
• Higher PA intensity and frequency were noted in the unsupervised group, with PA intensity predicting birth BMI.

Conclusions:

• Supervised exercise programs can be beneficial but are not essential for positively influencing pregnancy outcomes.
• The intensity of physical activity during pregnancy is the most critical factor affecting outcomes.
