Abstract
PURPOSE: The aim of the present study was to examine the influence of a supervised and regular program of aquatic activities throughout gestation on maternal weight gain and birth weight. DESIGN: A randomized clinical trial. SETTING: Instituto de Obstetricia, Ginecología y Fertilidad Ghisoni (Buenos Aires, Argentina). PARTICIPANTS: One hundred eleven pregnant women were analyzed (31.6 ± 3.8 years). All women had uncomplicated and singleton pregnancies; 49 were allocated to the exercise group (EG) and 62 to the control group (CG). INTERVENTION: The intervention program consisted of 3 weekly sessions of aerobic and resistance aquatic activities from weeks 10 to 12 until weeks 38 to 39 of gestation. MEASURES: Maternal weight gain, birth weight, and other maternal and fetal outcomes were obtained by hospital records. ANALYSIS: test were used; P values ≤.05 indicated statistical significance. Cohen's d was used to determinate the effect size. RESULTS: There was a higher percentage of women with excessive maternal weight gain in the CG (45.2%; n = 28) than in the EG (24.5%; n = 12; odds ratio = 0.39; 95% confidence interval: 0.17-0.89; P = .02). Birth weight and other pregnancy outcomes showed no differences between groups. CONCLUSION: Three weekly sessions of water activities throughout pregnancy prevents excessive maternal weight gain and preserves birth weight. TRIAL REGISTRATION: The clinicaltrial.gov identifier: NCT 02602106.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
