The physiologic and morphologic changes of pregnancy may interfere with the ability to engage safely in some forms of physical activity. A woman's overall health, including obstetric and medical risks, should be evaluated before prescribing an exercise program. Generally, participation in a wide range of recreational activities appears to be safe during pregnancy; however, each sport should be reviewed individually for its potential risk, and activities with a high risk of falling or those with a high risk of abdominal trauma should be avoided during pregnancy. Scuba diving also should be avoided throughout pregnancy because the fetus is at an increased risk for decompression sickness during this activity. In the absence of either medical or obstetric complications, 30 minutes or more of moderate exercise a day on most, if not all, days of the week is recommended for pregnant women.
怀孕期的生理和形态变化可能会影响安全参与某些体育活动的能力。在制定运动计划之前，应评估女性的整体健康状况，包括产科和医疗风险。一般来说，孕期参与多种娱乐活动似乎是安全的；然而，每项运动都应单独评估其潜在风险，孕期应避免有高跌倒风险或高腹部创伤风险的活动。整个孕期也应避免潜水，因为在此活动期间胎儿患减压病的风险会增加。在没有医学或产科并发症的情况下，建议孕妇每周大多数日子（若不是所有日子）每天进行30分钟或更长时间的适度运动。
