JSMPF：孕妇适当锻炼对宝宝成长有益

医生和研究人员已经通过研究证实，低出生体重的婴儿在以后的生活中患高血压的风险较高；近日，来自密歇根州立大学的研究人员通过研究首次揭示，怀孕女性的锻炼习惯实际上会降低所生婴儿将来患高血压的风险，即便婴儿出生时的体重较轻；相关研究刊登于国际杂志the Journal of Sports Medicine and Physical Fitness上。

研究人员James Pivarnik表示，通过分析观察一系列正常体重及体重较低的婴儿，我们发现，如果孕妇经常做锻炼，那么婴儿出生体重较低和高血压之间的关系就并不成立，这两者关系不成立就意味着锻炼或许可以以某种方式来改变婴儿出生后期患心血管疾病的风险。

目前这种现象和此前研究者提出的胎儿起源假说之间存在一定的关系，胎儿起源假说认为，如果怀孕母亲经历着某些艰苦的事情，那么婴儿在母亲体内的成长就会经历关键的生长期，而持久性的改变则会影响婴儿后期的健康。

文章中，研究人员对51名女性进行了长达5年的观察研究，研究者评估了这些女性的体力活动能力，比如在怀孕期及生产后的跑步和步行能力，在随后的研究中研究者发现，在一些孕妇中，尤其是其处于妊娠晚期时，有规律的锻炼和婴儿后期血压正常较低直接相关。因此这就告诉我们，怀孕时期有规律的锻炼或许对于婴儿具有明显的益处。

最后研究者Pivarnik说道，本文研究表明，母亲（怀孕女性）有规律的锻炼习惯或许对于儿童后期的成长具有明显的帮助。（生物谷Bioon.com）

However, a Michigan State University study is the first to suggest that the exercise habits of expecting moms can actually reverse this long-standing belief and possibly lower a child's chances of high blood pressure, even though they may weigh less at birth. High blood pressure, or hypertension, is a key factor in cardiovascular health.

The research is a start in getting at the issue of genetic preprogramming of a child's health characteristics while in the womb and can be found in the Journal of Sports Medicine and Physical Fitness.

"We looked at a range of normal birth weight babies, some falling at the lower end of the scale, and surprisingly we found that this lower birth weight and higher blood pressure relationship in these offspring is not supported if the women were physically active," said James Pivarnik, lead author and kinesiology professor at MSU. "The connection was disrupted, indicating that exercise may in some way alter cardiovascular risk that occurs in utero."

This phenomenon is linked to what's known as the fetal origins hypothesis. The theory suggests if something strenuous happens to a mother and her unborn child during critical growth periods in the pregnancy, permanent changes can occur that can affect the health of the baby.
