（单词翻译）

One Minute of Exercise May Be All You Need 每天一分钟运动有益健康

There is good news for people who think they do not have time to exercise.

对于那些认为自己没有时间运动的人来说，这是个好消息。

A group of researchers from a university in Canada recently published a study that says short bursts of high-intensity exercise are good for you.

加拿大一所大学一些研究人员最近发表了一份研究称，短暂的高强度运动对健康有益。

In fact, this kind of exercise is just as good as spending up to an hour riding a bike or running steadily¹.

实际上，这种运动和花费一小时时间稳固地骑自行车或跑步的效果相当。

The research team followed 27 men who were not very active for 12 weeks. They divided the men into three groups. One group did short, intense workouts on a bicycle three times a week. Another group rode a bicycle for about 50 minutes, three times a week. A third group did nothing.

该研究团队追踪记录了27名不那么积极运动的男子连续12周的时间。他们将这些男子分成几组。一组男子每周三次骑自行车进行短暂的高强度运动。另外一组每周三次骑自行车，每次50分钟。第三组什么运动都不做。

The researchers found something they did not expect. The group that exercised for only 10 minutes each session was just as healthy after 12 weeks as the group that exercised for 50 minutes each session.

这些研究人员发现了他们没有预料到的结果。12周之后，每一次只运动十分钟的一组和每次运动50分钟的一组健康状况相同。

That is because of the way the researchers organized the workouts.

这是因为研究人员安排锻炼的方式。

Each group started with a two-minute warm-up and finished with a three-minute cool-down. But in-between, the high-intensity group sprinted² for 20 seconds, followed by a two-minute recovery period. They did three sprints³ for a total of 10 minutes of exercise. This kind of exercise is known as interval⁴ training.

每一组都从两分钟的热身运动开始，以三分钟的放松活动结束。但是在这期间，高强度运动的一组短跑冲刺20秒钟，然后进行两分钟的恢复。他们在十分钟的运动时间内进行了三次冲刺。这种锻炼方式被称为间歇训练。

The lead author of the study says interval training is both time efficient and effective.

该研究首席作者表示，间歇训练既节约时间，又效果显著。
