剧烈的产前运动会降低出生体重吗？减少产妇运动会增加出生体重吗？怀孕期间锻炼有什么建议？我们招募了117名打算在怀孕期间每周锻炼5次或更多次的女性，以研究怀孕期间减少母亲运动量是否与出生体重增加有关。只有61/117（52%）的女性同意随机继续或减少（每周3次或更少的运动）其预期的妊娠运动计划。大多数拒绝随机化的妇女不想冒着被要求在怀孕期间减少运动的风险。在随机试验中，继续和减少运动计划的妇女所生婴儿的平均出生体重没有统计学显著差异。拒绝随机化的高比率限制了研究发现出生体重差异的能力，限制了结果的普遍性，并表明许多打算在怀孕期间进行这种水平运动的女性对运动持不妥协的态度。
Does strenuous antenatal exercise reduce birthweight? Does reducing maternal exercise increase birthweight? What to advise about exercise during pregnancy?We recruited 117 women who intended to exercise 5 or more times weekly during pregnancy to a study of whether reducing the amount of maternal exercise during pregnancy is associated with an increase in birthweight. Only 61/117 (52%) of women agreed to be randomised to either continue or to reduce (to 3 or fewer sessions of exercise weekly) their intended pregnancy exercise program. Most women who refused randomisation did not want to risk being asked to reduce their exercise during pregnancy.Within the randomised trial, there was no statistically significant difference between the mean birthweight of babies born to women who continued and those who reduced their intended exercise program. The high rate of refusal of randomisation limits the power of the study to find a difference in birthweight, limits the generalisability of the results and shows that many women intending to exercise at this level during pregnancy have an uncompromising attitude to exercise.
