New research shows that stiffness can also be dangerous to health as smoking.In a study published in the journal The Lancet, provides data on more than 53 million deaths worldwide in 2008, resulting in a poor physical activity.For comparison, the researchers note that smoking is responsible for about 5 million deaths worldwide each year."Lack of physical activity has a big impact on the health of people around the world.In fact, the effects of inactivity can be compared with smoking, "- said at a press conference and a researcher-Min Lee, Ph.D., an epidemiologist at the Harvard School of Public Health.
experts, who did not participate in this study, nevertheless doubted this statement.Tim Armstrong, MD, coordinator of the monitoring and disease prevention program coordinator of the World Health Organization (WHO) in Geneva, Switzerland, points out that his organization estimates that inactivity is a little less deaths - about 3.2 million deathsper year worldwide.
Armstrong believes that the Lancet, res
sedentary lifestyle can be very harmful
experts studying the impact of physical activity on the health of people praised the study for its wide coverage and accurate scientific approach."This is an excellent analysis," - says James Levine, MD, professor of medicine at the Mayo Clinic in Rochester, Minnesota."We know that as soon as someone gets up from his chair, the sugar level in his blood returned to normal, as well as cholesterol and triglyceride levels, and this is very consistent.Every time you get up, these levels return to normal.Every time you sit down, they rise. "
«If we add the fact that you spend in the chair for a long time, the cumulative effect of such immobility is not surprising, therefore, very dangerous," - says Levin.Other experts agree."Too little exercise plays an important role in almost all chronic diseases," - says John P. Tifolt, Ph.D., professor of nutrition and physiology of sport in the School of Medicine at the University of Missouri.It examines the impact of inactivity on health, but did not participate in this study."We have to adopt the smoking health enemy number one, and physical inactivity put right next to it," - he says.
How many people jeopardize their health, because they are inactive?Lancet A separate study determined that worldwide, at least one out of three adults and four out of five adolescents aged 13 and 15 do not comply with the recommended amount of physical activity.For adults it is 150 minutes per week of moderate physical activity, such as brisk walking.For teenagers, it's an hour of moderate physical activity every day.This study found that women of all ages are less active than men, and that with age people become less physically mobile.
Why are we so inactive?Around the world, researchers say, people often resorted to using cars and other vehicles in order to get to the desired location.In the US, for example, less than 4% of people walk to work, and less than 2% commute to work by bicycle.In comparison, about 20% of people walk to work in China, Germany and Sweden.More than 20% in China, Denmark and the Netherlands get to work on a bicycle.Worldwide, about 42% of people have reported that they sit for more than four hours per day.About 70% of teens said they watch TV more than two hours a day.
Tips for sedentary
Tifolt said that one of the proven and inexpensive ways for greater mobility, is wearing a pedometer.In one study, women who wore a pedometer with the aim to make at least 10,000 steps a day were more physically active than those who set a goal to walk on foot for 30 minutes a day.
While the pedometer will count the number of steps that you have gone, but he will not be able to show how fast you do it.The intensity of physical activity is also important.According to the recommendations of the 2009 study, published in the American Journal of Preventive Medicine, to ensure that your load reaches the average, try to walk about 3,000 steps in 30 minutes.
