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，少運动总比不运动好。但2022 年的一项研究发现，运动强度也会对你的健康产生影响。

当然，步行去商店对我们身体的影响并不像跑步10 公里那样大。但研究人员发现，对简单活动的微小改变可能会起到真正重要的作用。例如，研究人员说，与其散步14 分钟，还不如快走7 分钟对心脏更好。

研究人员查看了英国88000 多人的数据，这些人的平均年龄为62 岁。他们想知道人们的运动强度会如何影响他们的心脏疾病。

研究人员用这些人手腕上的监视器观察他们一周的体育活动。然后，研究人员又观察了大约七年，并记录下了这些人所有的心脏问题。

研究发现，虽然多运动会降低我们患心脏病的风险，但如果我们进行一些强度更大的活动，患心脏病的风险可能会更小。

研究人员写道，如果我们以中等强度进行20%而不是10%的运动，我们患心脏病的风险可以降低14%。然而，研究人员也写道，多做运动，不论什么强度都是有益的！
