Physical activity is associated with a reduced risk of developing chronic diseases, primarily diabetes mellitus, cardiovascular disease, and certain types of cancer. A sedentary lifestyle is the cause of 5.3 million deaths a year. However, since 2001, the world has not seen a significant increase in the level of physical activity in the world; in 2016, a quarter of the adult population remained inactive.
Scientists believe that due to the pandemic COVID-19-19 the problem of physical passivity has worsened. This is especially dangerous given the fact that people with chronic diseases are more likely to end up in hospitals and die from coronavirus infection.
The authors of the first study found that physical activity in 80% of adolescents did not meet the recommendations of the World Health Organization. That is, they move for less than one hour a day, and since 2012 this indicator has practically not improved. In addition, 40% of adolescents do not walk to school, 25% sit for more than three hours a day, in addition to the time spent studying.
According to data from 38 European countries, 60% of boys and 56% of girls watch TV at least two hours a day, and 51% of boys and 33% of girls play video games three hours or more a day. However, scientists point out that the health effects of long screen time are poorly understood today.
The authors of the study write that the pandemic, the accompanying distance learning and social dropping have led to a decrease in physical activity in children, the consequences of which can be felt throughout life.
The second study published in IN Lancetdedicated to physical activity among people with different types of disabilities. People from this group are 16-62% less likely than others to fulfill the WHO standards for physical activity. Scientists write that this increases the risk of exacerbating existing health problems and the emergence of new chronic diseases.
The study authors note that people with disabilities benefit from physical activity even if they do not spend the recommended 150 minutes per week. Its effects include improving cardiovascular and mental health, increasing muscle strength, and increasing independence.
In a third study, researchers tested whether mass sporting events, including the Olympics, promote physical activity. According to them, in the cities that hosted the Olympic Games, there have been no tangible changes in this regard.
“The Olympic Games and other mass sporting events are an untapped opportunity to influence health and physical activity not only in host cities and countries, but around the world. The Olympic Games provide a global audience that can be interested in physical activity. The challenge is transforming their enthusiasm into sustainable public health programs that are affordable and enjoyable for most people, ”explained study co-author Professor Adrian Bauman of Sydney. university.
The authors of the studies are convinced that very little is being done in the world to combat physical inactivity. Adolescents and people with disabilities are the groups of people whose activity is least likely to meet the WHO recommendations. Scientists are calling for global action to get the level of physical activity off the ground.
