How much exercise do you need to undo the harm of a life spent sitting down?
Exercising for as little as two-and-a-half hours a week can undo damage done by sitting down all day, a study has found.
研究發現,每周僅需2.5小時的鍛煉,就可抵消終日久坐帶來的危害.
The study by the University of Leicester found that even moderate activity can be enough for a health boost.
這項由英國萊斯特大學主持的研究發現,適度鍛煉足以保持身體健康.
Sedentary behaviour – any waking behaviour with low energy expenditure while in a sitting or reclining posture – has been linked to ill health.
久坐行為指清醒狀態下任何坐著或靠著的低能量消耗行為,這種行為與不佳的健康狀況直接掛鉤.
But medics are concerned as many British adults now spend between half and nearly three quarters of waking hours sitting.
然而,令醫療工作者擔心的是,如今許多英國成年人二分之一到四分之三的清醒時間都是坐著的.
Dr Thomas Yates, who worked on the study, said: "It is possible for an individual, over the course of a day, to have high levels of physical activity and still accumulate large amounts of sedentary time."
托馬斯·耶茨博士參與了此次研究,他表示："個體可以在一天中既進行高強度的運動又保持長時間的久坐."
