研究：走路慢的人思维也慢

长期以来，医生们一直利用步速对老年人的认知能力进行快速可靠的了解，因为人们越来越认识到，步态不仅与肌肉骨骼机制有关，还与中枢神经系统有关。

Until now, however, no one knew it could signify underlying brain health so much earlier in life.

然而，直到现在，没有人知道步速可能在生命的早期就预示大脑的潜在健康状况。

The correlation was so stark, however, that the US scientists now say walking tests could be used to provide an early indication of dementia.

美国科学家现在认为，这种关联非常明显，步行测试可以提供有关痴呆症的早期迹象。

dementia[dɪˈmenʃə]：n.痴呆

Published in the Journal of the American Medical Association, the study revealed an average difference of 16 IQ points between the slowest and the fastest walkers at the age of 45.

发表在《美国医学会杂志》上的这项研究表明，45岁时，走路最慢和最快的人之间平均相差16个智商值。

This reflected both the participants’ natural walking speed and the pace they achieved when asked to walk as fast as they could.

这既反映了参与者的自然行走速度，也反映了他们在被要求尽快行走时的速度。

Those with a slower gait also scored less well in both physical exercises, such as hand-grip strength and visual-motor coordination tests, as well as biological markers of poor health.
