A newly-released study reveals that walking fast in your old age is a sign you will live a long life. The report in the Journal of the American Medical Association analyzed data from nine studies that involved 34,485 senior citizens. Participants in the research were regularly tested over a period of 21 years. The researchers looked at the relationship between walking speed in the over-65s and expected longevity. They concluded that the faster an older person can walk, the longer they can expect to live. Lead researcher Dr. Stephanie Studenski said: "It’s a real part of the human experience to see that when someone slows down with age, they may not be doing as well as they once were."

一項最新發(fā)布的研究披露，老年時走路快是長壽的標(biāo)志?！睹绹t(yī)學(xué)會雜志》上這份報告分析了來自9份調(diào)查，包括34485名老年公民的數(shù)據(jù)。研究的參加者在21年的時間內(nèi)定期接受測試。研究人員查看了65歲以上的老人走路速度和長壽之間的關(guān)系。他們得出結(jié)論，老年人走路速度越快，他們的預(yù)期壽命越長。首席研究人員Stephanie Studenski博士表示：“這是人類經(jīng)驗的一部分，當(dāng)一個人隨著年長走路速度慢下來的時候，他們的身體狀況可能不像以前那么好。”

Dr. Studenski explained why an elderly person’s walking pace could be an indicator of a longer life. She said walking involves the use of many bodily functions working in tandem. The heart, lungs, skeletal system and joints, muscles, nerves and brain must all work together to ensure a smooth and consistent speed. Damage to any of these systems could result in walking more slowly, which could signal medical problems. Studenski said that walking speed was a better indicator of longevity than other factors, and that elders who walked at “one metre per second or higher consistently demonstrated survival that was longer than expected by age and sex alone”. She also suggested doctors look more carefully at slow-walking patients.

Studenski博士解釋了為何老年人的走路速度是長壽的標(biāo)志。她表示，走路需要身體許多功能協(xié)同行動。心，肺，骨骼系統(tǒng)，關(guān)節(jié)，肌肉，神經(jīng)和大腦必須一起工作，確保速度流暢，一致。這些系統(tǒng)中的任何一個出現(xiàn)損傷都會導(dǎo)致走路速度變慢，意味著身體出現(xiàn)問題。Studenski博士說，走路速度比其他指標(biāo)更好地反映壽命的情況。每秒鐘走一米以上的老年人比僅僅看年齡或性別能夠更好地表明長壽。她還表示，醫(yī)生應(yīng)該更關(guān)注走路慢的病人。
