The latest results of influences of physical training during pregnancy on the foetus are presented. In humane, no pathological effects on the embryogenesis have been demonstrated. During exercise, a modest increase (5-25 bpm) in foetal heart rate is a common finding. This might be caused by reduced oxygen supply to the foetus, but could more likely be due to stimuli from vasoactive hormones or training-induced uterine contractions. Foetal growth seems to be influenced by maternal training, as moderate training has resulted in significantly bigger babies compared to both inactivity and hard training. In one study it was shown that low body weight in babies from hard-training mothers was due to reduced neonatal fat mass. Pathological sequelae due to increased maternal temperature during training have not been found in humans. The results strongly suggest that moderate training during pregnancy can be recommended if simple precautions are taken.
本文介绍了孕期体育锻炼对胎儿影响的最新研究结果。在人体研究中，尚未证实体育锻炼对胚胎发育有病理影响。运动期间，胎儿心率适度增加（5-25次/分钟）是常见现象。这可能是由于胎儿氧气供应减少，但更可能是由于血管活性激素的刺激或训练引起的子宫收缩。胎儿生长似乎受母亲锻炼的影响，因为适度锻炼的母亲所生婴儿比不锻炼和过度锻炼的母亲所生婴儿明显更大。一项研究表明，过度锻炼母亲所生婴儿体重低是由于新生儿脂肪量减少。在人类中尚未发现因锻炼期间母亲体温升高而导致的病理后遗症。结果强烈表明，如果采取简单的预防措施，孕期适度锻炼是可以推荐的。
