Scientists from Duke University (USA) conducted a study aimed at establishing exactly how much physical effort and training is needed every day to reduce the risk of cardiovascular disease and premature death. The article was published in the Journal of the American Heart Association, reports EurekAlert.
The specialists analyzed the data obtained during a long-term study involving 4,840 people over the age of 40. The lifestyle observations of the volunteers were conducted from 2003 to 2006, with all of them wearing accelerometers to quantify their daily physical exertion. By checking the national database, the scientists found that in 2011, 4,140 of the participants in the experiment remained alive.
It turned out that those whose physical activity did not last more than 20 minutes a day had the highest risk of premature death. One hour of exercise reduces the probability of premature death by half, and 100 minutes – by 76%. At the same time, climbing the stairs instead of taking the elevator, as well as brisk walking, are also beneficial for health, experts say.
According to the recommendations of the US Department of Health and Human Resources, at least 150 minutes of moderate physical activity should be spent per week, and these should be a complex of exercises lasting more than 10 minutes. However, the results of the new study show that activity can be sporadic and the time required for light physical activity can accumulate over the course of the day.Zdrave.to
