Going to gyms is the best way to exercise? Does exercise require well-being without income? Does exercise require a daily routine?
You may be surprised by the correct scientific answer to these questions, according to a study conducted by a research team at the Faculty of Health Sciences at Simon Fraser University of Canada.
The study concludes that regardless of the level of income of individuals, "the exercise of 150 minutes per week - divided by 30 minutes for five days - prevents 8.0% (1 per 12) of the world's deaths annually, and reduces infection rates Cardiovascular disease by about 4.6% (1 per 20) ".
They also found that "in the case of hyperactivity - which reaches more than 750 minutes of physical activity per week - it gives more positive indicators; mortality rates fall by 13%, and rates of cardiovascular disease by 9.5% .
The study involved more than 130,000 people between the ages of 35 and 70 from 17 countries with high and low economic levels for a period of 6 to 9 years to determine the effect of physical activity on life rates and the prevention of cardiovascular disease.
Canada, Sweden, the United Arab Emirates, Argentina, Brazil, Chile, Poland, Turkey, Malaysia, South Africa, China, Colombia, Iran, Bangladesh, India, Pakistan and Zimbabwe.
With the launch of the Lancet study, participants presented information on their economic and social levels and lifestyle, their family histories with cardiovascular disease, and provided information on their normal physical activity, which was renewed every three years at least.
"It does not matter what kind of physical activity a person does, it is not a requirement to go to the gymnasium," he said. "The time spent cleaning the house, or even walking briskly on the way to work, This framework ".
Motivating results
"Our findings will be more useful for people with low incomes, and we hope to be a catalyst for many to develop a routine," says Scott Lear, a specialist in cardiovascular disease prevention at the Simon Fraser University of Canada and principal investigator for the study. Daily exercise. "
"Staying active by doing homework can save money and resources on people with cardiovascular disease, and can be particularly helpful in low-income countries," he said, adding that "affordability of treatment and diet linked to heart disease Blood vessels, such as the consumption of fruits and vegetables, are often beyond the reach of many people in low- and middle-income countries, but physical activity is a low-cost approach to preventing cardiovascular disease. "
The study can be very useful in the face of what the World Health Organization (WHO) points out on its official website: "The problem of physical activity appears to be more pronounced in high-income countries: in 26% of men and 35% of women in high-income countries Compared to 12% of men and 24% of women in low-income countries. "
sudden death
"Without knowing the history of people, I can not be sure that exercise has led to death; in most of these cases people may have some heart disease," says Lear. Which do not show symptoms to individuals immediately until an emergency occurs. "
"What happens in some individual cases does not mean that physical activity or sport is bad or unhealthy. For example, a person may die while driving, but that does not mean that we will not drive the car, and that driving is generally dangerous to health. , And I think that if a person practicing sports of various types of walking or performing gymnastics in the gym, there may not occur a sudden drop in blood circulation, and therefore less sudden death rate.
Underlying heart problems
"The underlying heart problems are a major cause of many deaths that occur during exercise," said Mohammed Nasr, a professor of cardiology at the National Heart Institute. "The problem is usually due to a defect In the heart muscle, which drives sports clubs to perform ultrasound waves on the players involved in the newly; to ensure that this problem does not have.
"Smoking is one of the causes of sudden death during exercise. It leads to coronary stiffness, which makes it impossible to pump blood to the heart, especially with physical exertion."
"What is new in the latest study is the detailed information you have provided on the preferred rate of physical activity, which improves muscle, heart and respiratory fitness, and reduces the risk of blood pressure and coronary heart disease," he said.
The World Health Organization has recommended that people aged 18 to 64 be required to exercise for at least 150 minutes, but unfortunately, 23% of the world's population They implement the guidelines on physical activity approved by the organization.
