加拿大麦克马斯特大学研究人员开展的一项研究结果表明,学龄前儿童的体力活动对未来心血管健康有明显影响,是预防成年后心脏病的关键。

研究者发现,孩子从3岁左右开始加强运动,有利于促进血管健康,提高心脏适能。

研究者表示,很多人认为心脏病只有成年人尤其老年人才会得,但实际上血管在我们年幼时就已经开始硬化了。尽早开始实施任何一种预防措施都是很重要的,因此,要确保幼儿有足够运动的机会。

该研究纳入418名3~5岁的孩子,每年进行一次评估,连续评估3年。

评估内容包括体力活动量和心血管健康指标,例如,心血管适能(最大强度平板运动试验中的运动时间、1分钟心率恢复程度)、静息状态下的动脉僵硬度(全身脉搏波传导速度、颈动脉β僵硬指数)、坐位收缩压。

研究者发现,在学龄前儿童中,总体力活动和中高强度运动均可改善心血管适能,减轻血管僵硬度,但颈动脉除外,只有中高强度运动对颈动脉僵硬度有明显改善。

另外,在女孩中,中高强度运动还可减缓收缩压升高的速度。

研究者指出,这说明,对于学龄前儿童来说,运动强度对于促进血管健康很重要。孩子的血管获益主要来源于在户外精力充沛地玩乐,活动得越多,获益越大。
