一項研究數據顯示，全球有 14 億成年人缺乏運動，成為心臟病、癌癥等疾病的多發群體。本文用具體的數字說明了一周之內人們應做多長時間的運動才能保持健康。

People across the world need to get moving， according to a new study by the World Health Organization （WHO）.

5 percent of adults do not get enough exercise， according to the study. This number hasn’t changed from 2001. Because of this， about 1.4 billion people are close to deadly diseases such as heart disease and cancer.

People should do at least 150 minutes of “moderate intensity （中等強度）” exercise each week， such as dancing or swimming. They can also do 75 minutes of “vigorous intensity （高強度）” activity， such as running or playing soccer， according to the WHO.

As for how to exercise more， experts suggest we don’t have to go to the gym every time. For example， we can go up and down stairs a lot instead of taking the lift. If we don’t feel we can go to a dancing class each week， standing on one leg for 30 minutes a day is very good， too.

The study also found that women are less active than men， with 32 percent of women failing to exercise enough， compared to 23 percent of men. Women spend more time at home taking care of children and doing housework.

But unlike that in most other countries， men are less active than women in China， with 16.6 percent of men and 12 percent of women not getting enough exercise.
