Abstract

Seven women at 25 weeks' gestation exercised on land and in the water at 70% maximum oxygen capacity (VO2max) on a bicycle ergometer. Women had significantly lower heart rates and lower systolic blood pressures during immersion exercise. Women had a mean diuresis of 207 ml (6.5 ml/min) during water exercise compared with 98 ml. (2.4 ml/min) during land exercise. Fetal heart rates showed a tendency toward being higher after land exercise compared with water exercise. Six of seven fetuses displayed tachycardia after land exercise compared to one of seven after water exercise. Exercise on land and during immersion at 70% VO2max was well tolerated. However, exercise during immersion offers several physiologic advantages during pregnancy.

摘要

七名妊娠25周的女性在自行车测力计上以最大氧摄取量（VO2max）的70%进行陆地和水中运动。在水中运动时，女性的心率和收缩压显著降低。与陆地运动时的98毫升（2.4毫升/分钟）相比，女性在水中运动时的平均尿量为207毫升（6.5毫升/分钟）。与水中运动相比，陆地运动后胎儿心率有升高的趋势。七名胎儿中有六名在陆地运动后出现心动过速，而在水中运动后七名胎儿中只有一名出现心动过速。以VO2max的70%进行陆地运动和水中运动时耐受性良好。然而，孕期水中运动具有一些生理优势。
