Watching a horror film could burn off a whole bar of chocolate, according to new research released today.

根据今天发布的最新研究，观看一部恐怖片让人消耗的热量相当于一根巧克力棒所含的热量。

Viewers who put themselves through 90 minutes of adrenaline-pumping terror can use up as much as 113 calories, close to the amount burned during a half-hour walk and the equivalent to a chocolate bar.

看完90分钟恐怖片可以使人消耗多达113卡路里的热量，接近于散步半小时，或者一根巧克力棒所含的热量。

The movie top of the list of calorie-burners was found to be the 1980 psychological thriller¹ The Shining, with the average viewer using up a whopping 184 calories.

位居十大最能燃烧卡路里的恐怖片榜单之首的是1980年的心理惊悚片《闪灵》，平均每位观看者会消耗多达184卡路里的热量。

Jaws² took the runner-up spot, with viewers burning on average 161 calories, and The Exorcist came third, with 158 calories.

排在第二位的是《大白鲨》，观看者平均消耗161卡路里热量；排在第三的是《驱魔人》，平均消耗量为158卡路里。

The University of Westminster study measured the total energy expenditure³ of ten different people as they watched a selection of frightening movies.

这项研究由威斯敏斯特大学开展，评估了10名受访者在观看所挑选出的恐怖电影时的总能量消耗。

Scientists recorded their heart rate, oxygen intake⁴ and carbon dioxide output - and discovered the number of calories used increased by on average a third during the films.

科学家记录了他们的心跳、摄氧量和二氧化碳排出量，发现在观看恐怖片时，受访者的卡路里消耗平均增加了三分之一。

The research also revealed films featuring moments designed to make viewers jump in terror are the best calorie-burners, as they cause heart rates to soar.

研究还显示，设计有极度惊恐场景的电影消耗的热量最多，因为这能让观看者的心跳迅速加快。

Dr Richard Mackenzie, senior lecturer and specialist in cell metabolism⁵ and physiology⁶ at the University of Westminster, said: "Each of the ten films tested set pulses racing⁷, sparking an increase in the heart rate of the case studies.

理查德-麦肯齐博士说：“调查选用的十部恐怖片都会使人血脉贲张，使被调查者心跳加速。”麦肯齐博士是威斯敏斯特大学细胞代谢与生理学的高级讲师和专家。

"As the pulse quickens and blood pumps around the body faster, the body experiences a surge in adrenaline.

“随着心跳加快、全身血流加快，体内肾上腺素水平也随之上升。”

"It is this release of fast acting⁸ adrenaline, produced during short bursts of intense stress (or in this case, brought on by fear), which is known to lower the appetite, increase the Basal Metabolic⁹ Rate and ultimately burn a higher level of calories."

“正是由于身体里释放出能迅速起效的肾上腺素，导致基础新陈代谢率上升，最终使身体燃烧掉更多的卡路里。人体突然感受到强烈压力（在该研究中是由于恐惧）暴发时会释放肾上腺素，肾上腺素也会使人降低食欲。”

Helen Cowley, editor of the movie rental¹⁰ company LOVEFiLM - which commissioned the University of Westminster study - said: "We all know the feeling of wanting to hide behind the sofa or grab a pillow when watching scary or hair raising scenes, but this research suggests that maybe those seeking to burn some calories should keep their eyes on the screen."

委托开展该调查的电影租赁公司“爱情影片”的编辑海伦-考利说：“我们都曾有过看恐怖片时想躲到沙发后面或者抱住枕头的经历，但这项研究告诉我们，想减肥的人们应该盯紧屏幕。”
