只有少数人能坚持运动,科学家的话让我惊呆了
我们都知道运动有好处,我们都知道久坐不动没好处。但为什么我们中的大多数依旧久坐不动呢?这真是个让人不解的悖论。 说简单点,这都是我们的大脑惹的祸。新的研究发现,懒惰可能是我们在进化过程中发展出的一种生存技能,就和它对于很多其他动物来说一样,所以我们这么喜欢赖在沙发上真的一点也不奇怪。 "Conserving energy has been essential for humans' survival, as it allowed us to be more efficient in searching for food and shelter, competing for sexual partners, and avoiding predators," explains neuroscientist Matthieu Boisgontier from the University of British Columbia. In a new study, Boisgontier and his team tried to find out just how deeply rooted laziness is in our brains, by measuring our cognitive responses to different stimuli representing physical activity and sedentary behaviour. 受试者需要通过控制键盘来让小人儿走向运动图像、远离静止图像。 之后他们需要做相反的事:让小人儿走向静止图像、远离运动图像。 这项实验和以前的很多研究发现了相似的东西:人们在回避静止静止行为、走向活动行为的时候表现得更快。但这次的实验也显示出了一些新东西。 "The exciting novelty of our study is that it shows this faster avoidance of physical inactivity comes at a cost – and that is an increased involvement of brain resources," says Boisgontier. Boisgontier举了一个例子:比如,你去健身房健身,而健身房不在一楼,这时你下意识地就会坐电梯上去,而这和你来健身的目标根本就是相悖的。 不过他现在说: "I try to fight this too. I would never take the elevator or escalator to go to the gym now, because I'm aware of this." |
