研究發(fā)現(xiàn)，每周僅需2.5小時的鍛煉，就可抵消終日久坐帶來的危害。這項由英國萊斯特大學(xué)主持的研究發(fā)現(xiàn)，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?orreclining?posture—has?been?linked?to?ill?health.But?medics?are?concerned?as?many?British?adults?now?spend?between?half?and?nearly?threequarters?of?waking?hours?sitting.

久坐行為指清醒狀態(tài)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。然而，令醫(yī)療工作者擔(dān)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。[/cn]

Dr?Thomas?Yates,?who?worked?on?the?study,?said:"It?is?possible?for?an?individual,?over?thecourse?of?a?day,?to?have?high?levels?of?physical?activity?and?still?accumulate?large?amounts?ofsedentary?time."

The?study?published?in?BMC?Public?Health?used?data?from?the?2008?Health?Survey?to?paint?arepresentative?sample?of?English?adults.
這份發(fā)表在《英國醫(yī)學(xué)會公共衛(wèi)生》期刊上的研究報告引用了《2008年健康調(diào)查》中的數(shù)據(jù)，列舉了英國成年人的代表類型。

They?were?grouped?as?"Busy?Bees"—physically?active?with?low?sedentary?levels; "SedentaryExercisers"—physically?active?with?high?sedentary?levels; "Light?Movers"—physically?inactive,had?low?sedentary;?and?"Couch?Potatoes"—physically?inactive,?high?sedentary.
研究對象被歸為四個類型，他們分別是：“忙碌蜜蜂”——運(yùn)動充足且久坐時間短；“久坐鍛煉者”——運(yùn)動充足但久坐時間長；“輕量行者”——缺乏運(yùn)動但久坐時間短；以及“沙發(fā)土豆”——缺乏運(yùn)動且久坐時間長。

Dr?Yates?said: “Overall,?adults?who?engaged?in?at?least?150?min?of?moderate?to?vigorousphysical?activity?per?week,?including?'Sedentary?Exercisers',?had?more?favourable?health?profilescompared?to?'Couch?Potatoes'.
耶茨博士表示：“總的來說，包括‘久坐鍛煉者’在內(nèi)的成年人每周至少進(jìn)行150分鐘中高等強(qiáng)度的運(yùn)動，就能擁有比‘沙發(fā)土豆’更加理想的健康狀況?！?/div>

"By?suggesting?that?being?physically?active?may?offset?some?of?the?deleterious?consequencesof?routinely?engaging?in?high?levels?of?sedentary?behaviour,?this?study?further?emphasises?theimportance?of?physical?activity?in?the?promotion?and?maintenance?of?health."
“運(yùn)動可以抵消日常久坐帶來的消極影響，通過揭示這一點，此次研究進(jìn)一步強(qiáng)調(diào)了運(yùn)動對保持和促進(jìn)身體健康的重要性?！?/div>

PhD?student?Kishan?Bakrania?added: "This?research?is?significant?because?it?demonstrates?yetagain?why?physical?activity?and?exercise?is?so?important.
基尚·巴克讓尼亞是一名在讀博士生，他補(bǔ)充道：“這項研究意義重大，因為它再次證明了運(yùn)動鍛煉的重要性?！?/div>

"It?shows?that?people?who?spend?large?amounts?of?time?not?moving?either?through?work,?leisureor?lifestyle?can?counteract?some?of?the?negative?effects?of?sedentary?behaviour?by?regularlyexercising.
“它表明人們即便在工作或閑暇時不經(jīng)?；顒?，仍能通過定期鍛煉抵消久坐帶來的消極影響?！?/div>
