PLOS Genet:战胜肥胖基因!18000名汉族人数据显示,这6种简单运动或许能帮大忙!

大量数据显示,现代人有着越来越肥胖的趋势。不过,无论在什么环境下,都有人似乎怎么也吃不胖,而有的人却似乎“喝水都能胖”。科学研究也证明,遗传因素确实对肥胖具有一定作用,并且遗传因素能够与环境产生相互作用,对肥胖产生影响。

大量数据显示,现代人有着越来越肥胖的趋势。不过,无论在什么环境下,都有人似乎怎么也吃不胖,而有的人却似乎“喝水都能胖”。科学研究也证明,遗传因素确实对肥胖具有一定作用,并且遗传因素能够与环境产生相互作用,对肥胖产生影响。

好在,已经有研究表明,经常参加体力活动,可以减弱遗传因素对于肥胖的影响。

那么,具体哪些运动最能够抵消遗传因素对肥胖的作用呢?最近就有学者对于这个问题进行了研究。研究结果于8月1日发表在《公共科学图书馆杂志·遗传学》(PLOS Genetics)上。

这项最新研究分析的是遗传基因与自我报告的运动方式之间的相互作用。共纳入一万八千多名汉族成年人,年龄在30至70岁之间。研究人员专门研究了5种肥胖指标:体重指数(BMI)、体脂百分比、腰围、臀围和腰臀比,并请参加研究的受试者自己报告经常参加哪些运动(这项研究共分析了18种经常性运动)。

结果发现,经常进行运动可以减弱4种肥胖指标的遗传效应,包括BMI、体脂百分比、腰围、臀围。

在这18种经常性运动中,有6种减轻了至少一种肥胖指标的遗传效应。其中,经常慢跑对于所有5种肥胖指标的遗传效应都能减轻。爬山、散步、快步走、国标舞以及长时间瑜伽练习也减弱了BMI的遗传效应。

但是,令人吃惊的是,对于其他一些运动种类,诸如骑自行车、拉伸运动、游泳、跳舞机和气功等,这项研究却没有发现它们能改变任何肥胖指标的遗传效应。

这项研究结果表明,通过进行一些类型的运动,可以不同程度地降低肥胖指标的遗传效应。并且,肥胖的遗传倾向越是强的人,经常体育锻炼的好处越是大。

当然,这只是一项观察性的研究,并且各种运动种类的参与情况是依据受试者自己报告的数据,所以存在一定的局限性。另外,英国埃克塞特大学(University of Exeter)糖尿病和肥胖研究临床高级讲师Katarina Kos博士指出,有一些运动,比如篮球、网球、举重等,在这项研究中参与的人比较少,所以这项研究没有发现它们对于肥胖遗传风险的抵消作用,并不代表它们真的不存在,还需要进一步研究去发现。

不管怎么说,这项最新研究还是告诉我们一些简便易行的运动类型,可以对抗肥胖的遗传风险。所以不要犹豫,赶紧换上运动鞋和服装,运动起来,甩掉多余的脂肪,换回我们的健康吧!
