怀孕期间运动的价值存在争议。收益和风险都已被假设。由于经验证据很少，因此在一项前瞻性研究中对这个问题进行了调查，该研究评估了怀孕每个三个月母亲运动对胎儿生长的影响。 1987 年 1 月至 1989 年 6 月期间，从宾夕法尼亚州和纽约州的产科诊所招募了超过 800 名产前患者。受试者在进入护理机构时接受了采访，并在妊娠 28 周和 36 周时再次联系。对于既往有过不良后果或缺乏调理的女性，母亲运动与胎儿生长之间的关联是模棱两可的。在健康、低风险的产前患者中，运动与胎儿生长呈正相关。在中低运动水平下，调整后的平均出生体重比不运动者高出约 100 克（117 克；95% 置信区间为 17 至 217 克）。运动量越大，出生体重增加幅度越大，整个孕期运动能量消耗水平约为 2,000 kcal/周的出生体重增加接近 300 g（276 g；95% 置信区间为 54 至 497 g）。这些结果表明，美国妇产科医师学会发布的指南对于健康状况良好、低风险的产前患者可能过于严格。似乎有必要进行更多研究来更准确地定义安全限值。
The value of exercise during pregnancy is controversial; both benefits and risks have been hypothesized. As empiric evidence is scant, the issue was investigated in a prospective study that assessed the impact on fetal growth of maternal exercise in each trimester of pregnancy. A cohort of over 800 prenatal patients was recruited from obstetric practices in Pennsylvania and New York between January 1987 and June 1989 Subject were interviewed at entry into care and recontacted at 28 and 36 weeks of gestation. In women with prior adverse outcomes or a lack of conditioning, the associations between maternal exercise and fetal growth were equivocal. In fit, low-risk prenatal patients, exercise was positively associated with fetal growth. With low-moderate exercise levels, the adjusted mean birth weights were about 100 g higher than in nonexercisers (117 g; 95% confidence interval 17 to 217 g). With heavier exercise, larger birth weight increments were seen, close to 300 g in those who exercised throughout pregnancy at levels of about 2,000 kcal/week in energy expenditure (276 g; 95% confidence interval 54 to 497 g). These results suggest that the guidelines issued by the American College of Obstetricians and Gynecologists may be too stringent for well-conditioned, low-risk, prenatal patients. Additional research to define safe limits more precisely seems warranted.
