To review the current data regarding the safety of exercise in pregnancy.
MEDLINE search was limited to English literature between 1987 and 1995 with the key MeSH words exercise and pregnancy. Other sources included the Sports and Fitness Database between 1991 and 1995 and a manual search for relevant articles. Previous studies on the safety of exercise in pregnancy are limited in many ways and exhibit difficulties in controlling for confounding factors and in establishing associations while maintaining maternal and fetal safety.
Concerns about the effect of exercise on pregnancy include exercise-induced hyperthermia, birth weight changes, fetal heart rate responses, miscarriage, labour patterns, maternal injury, and maternal weight gain. Exercise during pregnancy also has many potential benefits.
Important gaps in our knowledge of exercise and pregnancy remain. Available data suggest, however, that moderate exercise on a regular basis during a healthy pregnancy has minimal risk for women and their fetuses.
回顾当前关于孕期运动安全性的资料。
MEDLINE检索仅限于1987年至1995年间的英文文献，关键词为运动和妊娠。其他来源包括1991年至1995年间的体育与健身数据库以及对相关文章的手工检索。以往关于孕期运动安全性的研究在许多方面存在局限性，在控制混杂因素以及在确保母婴安全的同时建立关联方面存在困难。
对运动对妊娠影响的担忧包括运动引起的体温过高、出生体重变化、胎儿心率反应、流产、分娩模式、母体损伤和母体体重增加。孕期运动也有许多潜在益处。
我们在运动与妊娠方面的知识仍存在重大空白。然而，现有数据表明，在健康孕期定期进行适度运动对女性及其胎儿的风险极小。
