抵消坐辦公室的不良影響需要一個小時的運動

At least an hour of physical activity a day may be required to offset the harmful effects of sitting at a desk for eight hours, according to the latest study to highlight the perils of a sedentary lifestyle.

根據最新關於久坐不動的生活方式的研究報道,每天至少一個小時的身體活動纔可能抵消八小時坐辦公室的有害影響。

The World Health Organisation (WHO) guideline, adopted by Public Health England, recommends 150 minutes of exercise a week but research, based on data from more than one million people, suggests that is insufficient for many.

在世界衛生組織(WHO)方針的指引下,英國公共衛生建議, 基於超過一百萬人的研究數據顯示，每週150分鐘的鍛鍊對大部分人是不夠的。

A team of international experts found that the risk of dying during a follow-up period of two to 18 years was 9.9% for those who sat for eight or more hours a day and engaged in low activity, compared with 6.8% for those who sat for less than four hours a day and were active for at least one hour a day.

國際專家小組發現, 在隨訪兩年到18年的期間內，對於那些一天久坐8小時或更長時間、身體運動量低的人來說，死亡的風險爲9.9%,相對於一天坐的時間小於4小時、身體運動至少一小時的人而言，這個指數爲6.8%。

But they also found that the increased risk of death associated with sitting for eight hours a day was eliminated for people who did a minimum of one hour of physical activity a day.

但他們也發現, 死亡風險的增加與一天坐8小時有關，一天至少做一小時運動的人能降低死亡風險。

Lead author Prof Ulf Ekelund, from the Norwegian School of Sports Sciences and Cambridge University, said: "You don't need to do sport, you don't need to go to the gym. It's OK doing some brisk walking, maybe in the morning, during lunchtime, after dinner in the evening. You can split it up over the day, but you need to do at least one hour."

來自挪威體育科學院和劍橋大學的首席作家烏爾夫-埃克隆德教授,說:"你不需要做運動、不需要去健身房。在早上、午餐時間期間、晚餐之後做健步走就可以了。一天內你可以分開做，但至少需要一個小時。"
