"Ordinary sports" reduces premature death by up to 40%

A methodological study that is the largest of its kind so far has revealed strong and convincing evidence that maintaining fixed or increasing levels of physical activity during the puberty period can significantly reduce the risk of death for general causes and cardiovascular disease, ranging from 20% and 40%. The study said that exercise contributes to reducing the possibility of early death due to illnesses, accidents or physical decline, that is, it extends the average life expectancy and protects against the main causes of death such as heart disease, cancer and strokes, and increases the chances of survival for a longer period. These results represent a qualitative leap in our understanding of the influence of physical activity in the long run, and highlight the shortcomings of previous studies that relied on one measurement of physical activity, which emphasize the importance of continuous detection of activity patterns during the course of life. Physical inactivity The physical inactivity is currently the fourth largest risk factor for death in the world and is closely related to a wide variety of non -communicable diseases. The World Health Organization recommends adults to practice 150 to 300 minutes per week of light physical activity, or 75 to 150 minutes per week of serious activity, or a mixture of the two. However, recent research suggests that the assessment of physical activity at a time does not reflect the changes in patterns of physical activity throughout the individual’s life, affecting the interpretation of long -term health benefits. The researchers analyzed data from 85 previous studies, which included more than 6.5 million people, and found that people who were regularly physically active through puberty would be less likely to die for any cause of 30 to 40% compared to those who remained inactive. As for those who started practicing physical activity at a later time in their lives, they performed less by 20 to 25%, which is a remarkable percentage that refute the idea that “time is missed”. The study did not stop there. On the contrary, I also found that the mere increased levels of physical activity, even if it was below the medical -recommend level, were linked to noticeable benefits for public health and longevity. These results hold the golden rule: “Moving is better than nothing, and starting late is better than not starting at all.” Physical activity, its health interest and its global challenges define physical activity and inert behavior: World Health Organization defines physical activity as any physical movement produced by structural muscles and requires energy spending, and includes movement during free time, transport or as part of work and home activities. Inactive behavior is any period of low energy spending during vigilance, such as sitting, lying or lying, and is related to increased obesity, poor heart health, metabolism and behavior in children and adolescents, and increases the risk of death with general causes, heart and blood diseases and cancer in adults. Health benefits of physical activity: For adults: Physical activity contributes to the prevention of non -infective diseases (such as cardiovascular disease, cancer, diabetes), and reduces symptoms of depression and anxiety, promotes brain health and improves general luxury. For children and adolescents: promote bone health, support muscle health growth, improve motor and cognitive development. Disturbing inactivity rates and excessive costs: 31% of adults and 80% of adolescents do not meet the recommended levels of physical activity worldwide. Global goals seek to lower the levels of physical inactivity by 10% by 10%, and 15% by 2030 compared to 2010. WHO recommendations: Provide global instructions for the amount of physical activity required for all age groups such as children, adolescents, adults, elderly, pregnant women and after birth, and even people with chronic cases and disabilities. The organization argues that any degree of physical activity is better than nothing, and that all physical activity is calculated, and that all age groups should reduce the time assigned to sitting. Global differences and influential factors: Women are less active than men with an average of 5 percentage points, and that has not changed since 2000. Physical inactivity levels in men and women increase after the age of 60. 81% of teenagers (11-17 years) were physically inactive, and teenage girls were less active than boys. Physical activity levels are influenced by individual, social, cultural, environmental and economic factors. The study shows that even those who did not reach the recommended movement limit also have a clear decline in the risk of death, which is considered a happy news for those who find it difficult to meet strict sports programs. Among the striking results shown by the study, those who started physically active and then stopped did not have the same long -term benefits in health as the groups set up that continued to maintain an active lifestyle. Regarding the causes of death, physical activity was found to have more influence on the prevention of cardiovascular disease, as the risk of death decreased by 40% in regular active people. In terms of cancer, physical activity is linked to a decrease in the risk of death by 25%, although the evidence remains less beautiful compared to heart disease. Sports physiology and sports create deep physiological changes in the cardiovascular system, which is considered one of the strongest causes that extend regular physical activity and occur death. If exercise exercises regularly, the size of the heart increases, and it becomes stronger and more efficient to pump blood, reducing the heart rate during rest, and increasing the blood flow to muscles and vital organs. Exercise also expands the blood vessels and improves their elasticity, reducing blood pressure and reducing the risk of atherosclerosis. With each heartbeat, the body becomes more capable of producing oxygen and nutrients for each cell, reducing the possibility of heart attacks and strokes, which is one of the most important causes of sudden death. In addition, exercise lowers harmful cholesterol levels and increases good cholesterol, which contributes to the protection of the arteries against sclerosis and blockage. The study improves the sensitivity of the body cells for the insulin hormone. During physical activity, the muscles pull glucose out of the blood to use it as an energy source, leading to a direct decrease in blood sugar levels. Over time, the body becomes more effective in the use of insulin, which protects from the development of type 2 diabetes, and this prevents the condition from worsening if it has already been diagnosed. As diabetes is directly related to an increase in the risk of heart disease, renal failure, blindness and other complications that can lead to death, the effect of exercise in combating this disease is one of the most important causes that make it a physiological factor that is protected from death. Regular exercise reduces the levels of inflammatory substances in the body, such as CRP and IL-6 protein, associated with an increase in the risk of chronic diseases such as cancer, heart disease and Alzheimer’s. Chronic inflammation, even if low, works to “destroy” the tissue of the body in the long run, and accelerates the aging of cells and the damage of the organs. The physical activity restores the balance of the immune system, increases the production of natural antioxidants and reduces the ‘oxidative pressure’ that accelerates the deterioration of the DNA. In this way, sport serves as an anti -inflammatory shield, which retains the tissue of the body and slows down biological aging, which is directly reflected at the rate of survival and prevention of early death. Physiologically, physical exercises increase the blood flow to the brain, which means better access to oxygen and nutrients. Sports also stimulate the release of substances such as the neuromedia derived from the brain, which helps with the growth of new neurons and strengthen the ties between existing neurons. These changes improve memory, attention and executive thinking function and reduce the risk of dementia and Alzheimer’s disease. It is known that cognitive decline is linked to an increase in the risk of death, either directly or by falling, food neglect or wrong medication. The loss of muscle mass and stimulating regular exercises, especially resistance exercises and lifting weights, producing protein in the muscles and the loss of muscle mass associated with aging, which is the case known as “Sarcopinia”. The mechanical pressure of exercise also stimulates bone construction cells, which increase bone density and reduce the risk of fractions and fragility. In the elderly, the loss of muscle and large mass is one of the hidden causes of death. The fall that seems simple can lead to a hip fracture and then a series of physical and mental decline ending with death. Maintaining a strong structure for the body is another defensive line that sports we offer, as sport contributes to organizing the work of the endocrine, and it improves the secretion of hormones such as cortisol, endorphins, dopamine and reduces the levels of stress and anxiety. It also increases the quality and depth of sleep, which is a substantial element in cell regeneration and heart health. Chronic sleep disorders are related to an increase in the risk of diabetes, obesity, depression and heart disease, all of which are factors associated with early death. The study concluded that those who practiced a moderate to strong physical activity at a rate that recommended the maximum did not achieve a great extra advantage in lowering the death rates. As for those who meet the recommended rates, they have achieved almost the maximum benefits, which means that achieving this level is very sufficient for better health, and there is no need for exaggeration or physical exhaustion. Although most of the studies on the analysis were based on self -reports (it can sometimes be inaccurate), the results remain of utmost importance. The researchers emphasized that physical activity should not only be a goal for the sport, but that it must be a natural part of everyone’s life, because they emphasized that public health campaigns should not only target those who do not exercise, but also those who practice to retain their continuity.
