目的：我们的目的是检验零假设，开始定期，中等强度的运动在怀孕早期没有影响fetoplacentalgrowth.Study设计：46名妇女谁没有经常行使：随机分配在8周要么没有运动（n = 24）或负重运动（n = 22）3至5次，每周为其余的怀孕。结果变量包括产前胎盘生长率和新生儿和胎盘形态测量measurements.RESULTS：运动妇女的后代比对照妇女出生的后代明显更重（校正出生体重：3.75 +/- 0.08 Mg vs 3.49 +/- 0.07 Mg）和更长（51.8 +/- 0.3 cm vs 50.6 +/- 0.3 cm）。出生体重的差异是瘦体重和脂肪量增加的结果。此外，运动组孕中期胎盘生长速度更快（26 +/- 2 cm（3）/wk vs 21 +/- 1 cm（3）/wk），胎盘功能的形态测量指数更大。有新生儿体脂百分比，头围，体重指数，或产妇weight gains.CONCLUSIONS：这些数据表明，开始在怀孕早期的负重锻炼的适度方案增强胎儿胎盘的生长没有显着差异。
OBJECTIVE: Our purpose was to test the null hypothesis that beginning regular, moderate-intensity exercise in early pregnancy has no effect on fetoplacental growth.STUDY DESIGN: Forty-six women who did not exercise regularly were: randomly assigned at 8 weeks either to no exercise (n = 24) or to weight-bearing exercise (n = 22) 3 to 5 times a week for the remainder of pregnancy. Outcome variables included antenatal placental growth rate and neonatal and placental morphometric measurements.RESULTS: The offspring of the exercising women were significantly heavier (corrected birth weight: 3.75 +/- 0.08 Mg vs 3.49 +/- 0.07 Mg) and longer (51.8 +/- 0.3 cm vs 50.6 +/- 0.3 cm) than those born to control women. The difference in birth weight was the result of an increase in both lean body mass and fat mass. In addition, midtrimester placental growth rate was faster (26 +/- 2 cm(3)/wk vs 21 +/- 1 cm(3)/wk) and morphometric indexes of placental function were greater in the exercise group. There were no significant differences in neonatal percentage body fat, head circumference, ponderal index, or maternal weight gain.CONCLUSIONS: These data indicate that beginning a moderate regimen of weight-bearing exercise in early pregnancy enhances fetoplacental growth.
