Everyone knows that exercise is good for the heart. Many people also do a lot of exercise to keep their body and heart right. But, in a recent research, it was told that due to excessive exercise, the arteries carrying blood to different parts of the body can be blocked. Since then many doubts have arisen in the minds of the people. Now Matthew Farrow, Lecturer of Anatomy and Musculoskeletal Department, University of Bradford, UK, has given his opinion while resolving the doubts of the people.
CAC score of people who work hard
This study, which blocked the arteries of Hart, had also made a lot of headlines. It found that more active people had higher coronary artery calcium (CAC) scores than less active people. The CAC score measures the amount of calcium in the walls of the coronary arteries – the arteries that supply blood and therefore oxygen to the heart muscle.
Increased calcium risk of heart attack
An increase in calcium in the coronary (heart) arteries can increase a person’s risk of a heart attack because the presence of calcium in the coronary arteries is a sign that a layer may be forming, known as atherosclerosis. The buildup of this layer is usually the result of an unhealthy lifestyle, such as smoking, drinking alcohol, being overweight and not getting enough exercise. That’s why doctors often use the CAC score to identify people at risk for heart disease.
South Korea and American scientists did research
Researchers from the University School of Medicine in South Korea and the Johns Hopkins Bloomberg School of Public Health in the US measured coronary artery calcium intakes of more than 25,000 healthy adults (predominantly male) aged 30 years and older between March 2011 and December 2017. analysed. Two comprehensive investigations were conducted to monitor changes in the coronary arteries of these adults during the study period.
The purpose of the research was to find out the relationship
The researchers wanted to find out whether there was a link between physical activity and an increase in coronary artery calcification. All of them were asked to complete a questionnaire to find out how much exercise they did each week. Nearly half the participants (47 percent) were classified as inactive, 38 percent as being moderately active and 15 percent as more active (the equivalent of running 6.5 kilometers a day). was classified.
Scientists got this result
Scans performed at the start of the study showed an average CAC score of 9.5 in the inactive group, 10.2 in the moderately active group, and 12 in the more active group. At the end of the study period, those who were moderate and more active saw an increase in their average score from 3 to 8. Therefore, with moderate and excessive exercise, calcium starts to accumulate in the arteries.
Exercise does not risk heart attack, keep doing it
However, the researchers found no association between higher coronary artery calcium scores and cardiovascular events, such as heart attack or stroke, due to exercise. So reports that claim that exercise ‘increases heart attack risk’ are both false and dangerous. The researcher cautioned against such an interpretation. Their conclusion was: The cardiovascular benefits of physical activity are undeniable.
