OBJECTIVE: To evaluate whether a 12-week supervised exercise program promotes an active lifestyle throughout pregnancy in pregnant @entity1 with @entity28 . METHODS: In this preliminary randomised trial, pregnant @entity1 (body mass index >=  30 kg/m2) were allocated to either standard care or supervised training, from 15 to 27 weeks of gestation. Physical activity was measured by accelerometry at 14, 28 and 36 weeks, while @entity410 ( @entity26 consumption (VO2) at the anaerobic threshold), nutrition (caloric intake and macronutrients percentage) and anthropometry were assessed at 14 and 28 weeks of gestation. Analyses were performed using repeated measures ANOVA. RESULTS: A total of fifty (50) @entity1 were randomised, 25 in each group. There was no time-group interaction for time spent at moderate and vigorous activity (pinteraction = 0.064), but the exercise group's levels were higher than controls' at all times (pgroup effect = 0.014). A significant time-group interaction was found for daily physical activity (p = 0.023); similar at baseline ((22.0    6.7 vs 21.8    7.3) x 104 counts/day) the exercise group had higher levels than the control group following the intervention ((22.8    8.3 vs 19.2    4.5) x 104 counts/day, p = 0.020) and at 36 weeks of gestation ((19.2    1.5 vs 14.9    1.5) x 104 counts/day, p = 0.034). Exercisers also gained less weight than controls during the intervention period despite similar nutritional intakes (difference in weight change = -0.1 kg/week, 95% CI -0.2; -0.02, p = 0.016) and improved @entity410 (difference in @entity410 change = 8.1%, 95% CI 0.7; 9.5, p = 0.041). CONCLUSIONS: Compared with standard care, a supervised exercise program allows pregnant @entity1 with @entity28 to maintain @entity410 , limit weight gain and attenuate the decrease in physical activity levels observed in late pregnancy. TRIAL REGISTRATION: ClinicalTrials.gov NCT01610323.
