Doctors share 11-minute exercise that can cut risk of cancer and heart disease

Cancer Disease University of Cambridge

Research has found that by just walking for 11 minutes a day, a person can slash their risks of early death.

Adults should generally be getting around 150 minutes of moderate exercise, or 75 minutes of vigorous exercise, every week, according to UK health officials.

Although many people would assume that a lot of exercise is needed to maintain tip top health, it turns out that even doing a small amount of exercise each day - like going for a brisk walk - is a lot better than nothing.

This is recommended by experts at the University of Cambridge, who revealed in a study, published on Tuesday in the British Journal of Sports Medicine, that one in 10 premature deaths could be prevented if the person did at least half the advised amount of physical activity.

Dr Soren Brage from the MRC Epidemiology Unit said: "If you are someone who finds the idea of 150 minutes of moderate-intensity physical activity a week a bit daunting, then our findings should be good news. Doing some physical activity is better than doing none.

"This is also a good starting position – if you find that 75 minutes a week is manageable, then you could try stepping it up gradually to the full recommended amount."

What counts as moderate-intensity physical activity?

Moderate-intensity physical activity raises your heart rate and makes you breathe faster, but you would still be able to speak during the activity. Examples include:

Brisk walking
Dancing
Riding a bike
Playing tennis
Hiking

Through extensive data analysis of published evidence, academics from the Medical Research Council (MRC) Epidemiology Unit at the University of Cambridge determined how much physical activity could positively impact several chronic diseases.

Scientists found that outside of work-related physical activity, two out of three people reported activity levels below 150 minutes per week of moderate-intensity activity, and fewer than one in 10 managed more than 300 minutes.

Those who completed over 150 minutes of weekly moderate exercise saw only marginal benefits in terms of reduced risk of disease or early death, but even half this amount came with noticeable improvements.

Accumulating 75 minutes per week of moderate-intensity activity brought with it a 23 per cent lower risk of early death. The same amount was also enough to reduce the risk of developing cardiovascular disease by 17 per cent and cancer by seven per cent.

The researchers calculated that if everyone in the studies had done at least 150 minutes per week of moderate exercise, around one in six - 16 per cent - of early deaths would be prevented. One in nine - 11 per cent - cases of cardiovascular disease and one in 20 - five per cent - of cancer cases would be prevented.

However, even if everyone managed at least 75 minutes of the same physical activity, this would prevent around one in 10 - 10 per cent - of early deaths. Five per cent, or one in 20, cases of cardiovascular disease, and nearly one in 30, or three per cent, of cases of cancer, would be prevented.

To come to these conclusions, academics examined results reported in 196 peer-reviewed articles, covering more than 30 million participants from 94 large study cohorts. Through this, researchers produced the largest analysis to date of the association between physical activity levels and the risk of heart disease, cancer and early death.

If you're not used to regular exercise, the good news is that your amount of physical movement can be worked into your daily routine.

Dr Leandro Garcia from Queen’s University Belfast said: "Moderate activity doesn’t have to involve what we normally think of exercise, such as sports or running. Sometimes, replacing some habits is all that is needed.

"For example, try to walk or cycle to your work or study place instead of using a car, or engage in active play with your kids or grandkids. Doing activities that you enjoy and that are easy to include in your weekly routine is an excellent way to become more active."
