You may know that a little exercise is better than no exercise. But a 2022study has found that the intensity1 of your exercise can have an impact2 onyour health， too.

Of course， a walk to the shops does not have the same effect3 on ourbodies as running 10 kilometers. But researchers found that small changes tosimple4 activities could make a real difference. For example， the researchers saythat， instead5 of going for an easy 14-minute walk， it’s better for your heart ifyou go for a faster seven-minute walk.

The researchers looked at data from more than 88，000 people in the UK，with an average6 age of 62. They wanted to see how the intensity of people’sexercise impacted their heart disease7.

Those people’s physical activity was watched for one week using monitors8on their wrists9. The researchers then watched them for around seven more years.They took notes on any heart problems of those people.

It was found that， while just doing more exercisegives us smaller risk of heart disease， it could be evensmaller if we do some of our activity with greater intensity.

The researchers wrote that if we do 20%—instead of 10%—of our exercise at a moderate10intensity， it could cut down our risk of heartdisease by 14% . However， the researchers alsowrote that more activity of any intensity is helpful！

你可能知道，少運動總比不運動好。但2022 年的一項研究發現，運動強度也會對你的健康產生影響。

當然，步行去商店對我們身體的影響并不像跑步10 公里那樣大。但研究人員發現，對簡單活動的微小改變可能會起到真正重要的作用。例如，研究人員說，與其散步14 分鐘，還不如快走7 分鐘對心臟更好。

研究人員查看了英國88000 多人的數據，這些人的平均年齡為62 歲。他們想知道人們的運動強度會如何影響他們的心臟疾病。

研究人員用這些人手腕上的監視器觀察他們一周的體育活動。然后，研究人員又觀察了大約七年，并記錄下了這些人所有的心臟問題。

研究發現，雖然多運動會降低我們患心臟病的風險，但如果我們進行一些強度更大的活動，患心臟病的風險可能會更小。

研究人員寫道，如果我們以中等強度進行20%而不是10%的運動，我們患心臟病的風險可以降低14%。然而，研究人員也寫道，多做運動，不論什么強度都是有益的！
