In spite of an extensive knowledge of the physiologic features of exercise during pregnancy, we still lack a comprehensive understanding of the effects of different types, intensities and duration of exercise throughout pregnancy on maternal and fetal well being. The aim of the current study was to examine the influence of an aerobic exercise program throughout pregnancy on gestational age at the moment of delivery.
This study was a randomized controlled trial. Three hundred and twenty Caucasian (Spanish) healthy pregnant women with singleton gestation were randomly assigned to either an exercise (n = 160) or a control (n = 160) group. Gestational age (weeks) and other outcomes were measured. The exercise program included 85 sessions (general fitness class, 3 times/week, 55-60 min/session from weeks 8-10 to weeks 38-39 of pregnancy).
Two hundred and ninety women were analyzed (exercise group EG, n = 138, control group CG, n = 152). The mean gestational age did not differ between groups (EG= 39.7 ± 1.3 vs CG= 39.6 ± 1.1 weeks, P = .81). Relative to preterm deliveries in EG we found 6 (4.3%) and 11 (7.2%) in CG, (P = .73).
A supervised program of moderate exercise performed throughout pregnancy is not a risk of preterm delivery for healthy pregnant women.
尽管我们对孕期运动的生理特征有广泛了解，但对于孕期不同类型、强度和时长的运动对母婴健康的影响，仍缺乏全面认识。本研究的目的是探讨整个孕期有氧运动计划对分娩时孕周的影响。
本研究为随机对照试验。320名单胎妊娠的白人（西班牙裔）健康孕妇被随机分为运动组（n = 160）和对照组（n = 160）。测量孕周（周）及其他结局指标。运动计划包括85节课程（一般健身课程，每周3次，每次55 - 60分钟，从妊娠第8 - 10周到第38 - 39周）。
对290名女性进行了分析（运动组EG，n = 138；对照组CG，n = 152）。两组间的平均孕周无差异（EG = 39.7 ± 1.3周 vs CG = 39.6 ± 1.1周，P = 0.81）。相对于运动组的早产情况，对照组分别有6例（4.3%）和11例（7.2%），（P = 0.73）。
整个孕期进行的有监督的适度运动计划对健康孕妇而言并非早产风险因素。
