New and important guidelines have been issued today outlining the amount of exercise adults and children need to do to stay healthy.
Newspapers and other media outlets have picked up on the angle that, for the first time, the new guidelines include recommendations for children under the age of five.
However, these new guidelines, issued by the chief medical officer, go much further and should be read and acted on by all adults in England.
They are based on a comprehensive review of the latest scientific evidence regarding physical activty and health.
The new guidelines include the following points:
The guidelines, which are now much more in line with those used in the US, also include recommendations for muscle-building and bone strengthening activities such as lifting weights and yoga.
The amount of exercise you need to do each week depends on your age. Use the links below to find out how much exercise you should be doing:
To stay healthy, adults aged 19-64 should try to be active daily and should do at least:
150 minutes (2 hours and 30 minutes) of moderate-intensity aerobic activity such as cycling or fast walking every week, and
muscle-strengthening activities on two or more days a
week that work all major muscle groups (legs, hips,
back, abdomen, chest, shoulders and arms).
75 minutes (1 hour and 15 minutes) of vigorous-intensity aerobic activity such as running or a game of singles tennis every week, and
muscle-strengthening activities on two or more days a
week that work all major muscle groups (legs, hips,
back, abdomen, chest, shoulders and arms).
An equivalent mix of moderate- and vigorous-intensity aerobic activity every week (for example two 30-minute runs plus 30 minutes of fast walking), and
muscle-strengthening activities on two or more days a week that work all major muscle groups (legs, hips, back, abdomen, chest, shoulders and arms).
The new physical activity guidelines drew upon an extensive body of research, including some large-scale evidence reviews conducted by the World Health Organization and in other developed countries. In particular, the guidelines were formulated after consideration of a US Government report looking at the health benefits of physical activity. This report was based on the findings of a comprehensive two-year review examining a large body of relevant research. The new UK guidelines also take into account the results of a similar Canadian evidence review.
The authors of these UK guidelines said that given these recent large-scale reviews it was unnecessary to undertake a full review of the primary literature, but they agreed upon a set of key primary evidence sources that would underpin the new UK guidelines. These sources were:
In addition, the evidence and draft guidelines were examined by an expert panel of leading international and national experts in the field of physical activity. The guidelines in development then went through various stages of presentation, consultation and feedback. The focus was on developing recommendations for new physical activity guidelines for the prevention of disease.
At present, only a minority of people in the UK get enough exercise. Based on the long-standing guidelines of achieving 30 minutes activity on at least five days, the following proportions of people meet their target activity levels:
Furthermore, according to self-reported measures of sedentary behaviour, approximately two-thirds of adults spend more than two hours a day watching TV and using the computer, and significant proportions of adults report spending between three to four hours sitting down during their leisure time.
The proportion of children meeting current targets are:
For those aged under five, the report says that UK data is only available for three- and four-year-olds, and shows that the mean total time spent being physically active is 120-150 minutes a day, with 10-11 mean hours spent being sedentary.
