Default 女子锻炼对下一代有良好影响

俗话说:“母壮子肥”。女子经常参加体育锻炼,无疑会增强体质,提高身体的抗病能力,对下一代 有利。
婴儿先天发育生长是后天的生长发育的基础。有人用智力评分的方法对婴儿出生体重与智力发育之间的关系进行过 研究,认为出生体重大的孩子的智力得分多,这是因为新生儿的大脑结构和神经细胞数目都已接近成人,重量可达 成人的1/3。
婴儿出生9个月后,http://sns.wowa.cn/,自身才能开始制造抗体。所谓抗体就是针对侵入身体的病源体所产生的一种物质,http://model-railroad-hobbyist.com/。所以9个月以内婴儿的抗病能力主要依靠母体。经常锻炼身体的女子.抗病能力无疑会提高,这样也提高了婴儿 抵抗疾病的能力。
再从分娩过程来看,常锻炼的妇女优于不锻炼的妇女。因为分娩时,胎儿能顺利娩出,则视产妇的产力而定。产力 有两种,一是子宫肌肉本身的收缩力,http://www.zjoubbs.com/,另一种是腹壁肌、隔肌、盆底肌的收缩力。锻炼有素的产妇,全身肌肉状态良好,辅助分娩的肌肉 强而有力,http://xtqxzf.gov.cn/,因而胎儿娩出比较顺利。由于锻炼,腹壁和子宫腔的肌肉更有弹性,腹压正常还能防止胎位不正或子宫异常位而 引起的难产。
妇女加强体育锻炼,特别是腹部肌肉的锻炼,对分娩是十分有利的。
