運動理論上可以戒煙，但是不能徹底幫助戒煙，也許你有煙癮了，去運動五分鐘，隔個一分鐘又渴望吸煙了，接著……
Even short bouts（一輪,一陣） of light exercise such as strolling（散步） can help smokers quit by reducing cigarette cravings（渴望） and withdrawal symptoms(癥候), say scientists at the University of Exeter in the UK.
The study is published in the April edition of the journal Addiction.
The scientists suggest that a short session of moderate(適度的) exercise, lasting for as little as five minutes, is sufficient（足夠的） to reduce cravings for a cigarette.
"People who struggle to give up smoking could make things much easier for themselves by taking just moderate exercise," said lead author Dr Adrian Taylor of the University of Exeter's School of Sport and Health Sciences.
"Not only may it help prevent weight gain but it will also help control the cravings and withdrawal symptoms that often lead to relapse," he added.
With today, 14th March, being National No Smoking Day in the UK, it is expected that one third of UK smokers (around 4 million people) will try to give up and 85,000 will do so for good.
Dr Taylor and his co-authors reviewed 12 studies on the effect of a single session of exercise compared to no exercise on three outcome measures: cigarette cravings, withdrawal symptoms and smoking behaviour. All reported beneficial impact on （對...之影響）at least one of the three outcome measures.
The papers they reviewed covered between them nearly 1,400 people who rarely exercised and in all but one study stopped smoking during the period of the experiment.
The participants(參加者,參與者) were assessed(已審估的) while they were doing the exercise using single and multi-item questions on cravings, symptoms of withdrawal and negative affect, the results of which reduced rapidly during exercise and remained reduced for up to 50 minutes afterwards.
Most of the studies on withdrawal symptoms showed a significant reduction in 2 of 6 symptoms: stress, restlessness, irritability, anxiety, tension and poor concentration.
Most of the studies showed increasing reductions in cravings and withdrawal symptoms with increasing duration and intensity of exercise, but even a short 5 minute seated exercise showed beneficial effects.
Four of the studies reported that the delay in lighting up the first cigarette after doing the exercise lasted two and sometimes three times longer.
Three studies showed that mood improved with exercise, while one did not.
The review team concluded that even small doses of exercise should be recommended to help people manage cigarette cravings and withdrawal symptoms.
Dr Taylor said "If a drug revealed the same effects it would immediately be marketed as a valuable aid to help people quit smoking or cut down."
He and his colleagues called for further research to find out what the underlying mechanisms could be such as stress and the neurobiology(神經(jīng)生物學(xué)) involved. This could then lead to more effective and practical ways to help people give up smoking.
Dr Taylor and his team at the University of Exeter are also doing research using brain imaging. They are looking at how exercise affects the brain's mood centres, which could be how the appetite for cigarettes is reduced. They are supporting a national project called "Walk-2-Quit" and want to see exercise recommended by National Health Service smoking cessation clinics.

美聯(lián)社１３日報道說，英國?？巳卮髮W(xué)幾名科學(xué)家要求接受測試的煙民在想吸煙時做些簡單的運動，如散步、做體操和收緊肌肉等。結(jié)果發(fā)現(xiàn)，適當(dāng)?shù)倪\動，哪怕只有５分鐘，就可以讓煙民暫時克服對尼古丁的渴望。
主持研究的阿德里安·泰勒說，這是因為運動可以產(chǎn)生多巴胺，從而減輕煙民對尼古丁的依賴。
對此，倫敦大學(xué)學(xué)院教授羅伯特·韋斯特指出：“在理論上，可以通過運動來克服對尼古丁的一時渴望，但我們不知道運動是否可以幫助徹底戒煙。”韋斯特認(rèn)為，或許可以把運動和其他戒煙手段結(jié)合在一起，以便更有效地幫助煙民戒煙。
英國瑪麗女王學(xué)院醫(yī)院的醫(yī)生彼得·哈杰克建議說，如果普及一些在辦公桌前就可以進(jìn)行的運動，可能會有更多煙民通過運動戒煙。
