Moderate exercise 'good for heart'

Moderate exercise 'good for heart'

US scientists have found that a little physical activity, such as brisk walking and heavy cleaning on a regular basis, can reduce the risk of developing heart disease.

According to researchers at the Harvard School of Public Health, as little as 150 minutes of moderate exercise per week can reduce the risk of cardiac problems by 14%, compared with individuals who do not exercise.

The researchers said two-and-a-half hours of moderate exercises are beneficial but 300 minutes of activity per week will achieve even better results. It could cut down the risk by 20%.

For the research, the team analysed data from 33 studies of physical activity and heart disease. It also examined data from nine studies that looked at the actual amount of physical activity people are getting.

Jacob Sattelmair, from the Department of Epidemiology at the graduate school, said: "Recent studies have begun to assess the actual amount of physical activity people are getting and how that relates to their risk of heart disease."

Details of the research are published in Circulation, the journal of the American Heart Association.
