新奇事件簿 做家务并不能代替身体锻炼（在线收听）

A new study suggests housework is not the quality form of exercise many people consider it to be. The report even went as far as saying that those who did the most housework were usually those most overweight. The study is called, "Does doing housework keep you healthy? The contribution of domestic physical activity to meeting current recommendations for health". It questions whether physical activities such as do-it-yourself, gardening and housework are such good exercise. It acknowledges that any activity is better than none, but says, "there is a danger that those undertaking domestic 'chores' may assume that this activity is moderate intensity" and wrongly count it as proper exercise.

一项新的研究表明干家务并不是许多人认为的那样是一种有效的锻炼形式。报告甚至还称那些家务负担最重的人通常也是体重超重的人。这项研究叫作“干家务更健康？干家务的运动量与身体健康。”该研究对例如自己动手、园艺以及干家务等活动是否有益进行了质疑。该研究承认运动总比不锻炼要好，但是称那些干家务的人群会自认为这些是中等强度运动，并误认为这些是适当运动，这是非常危险的。

A total of 4,563 adults participated in the survey, which was based on participants' weekly physical activity. The analysis from this research showed that people who included housework as part of their weekly exercise tended to be heavier. Research leader professor Marie Murphy said: "Housework is physical activity and any physical activity should theoretically increase the amount of calories [burnt]. But we found that housework was inversely related to leanness, which suggests that either people are overestimating the amount of moderate intensity physical activity they do through housework, or are eating too much to compensate for the amount of activity undertaken."

有总共4563名成年人参加了该研究，该研究是以研究对象每周的锻炼为基础的。分析称那些将家务看做是每周活动一部分的人群体重偏重。研究组长玛丽·墨菲教授称：“家务是体力运动，任何体力活动从理论上说都应该消耗卡路里。但是我们发现干家务却不会让人们减肥，这就表明人们或许是高估了干家务所带来的锻炼强度，或者是为了补偿消耗而食用了过多食物。
