You must have heard or read about the many benefits of exercise or physical activity. To prevent many diseases, to diagnose many diseases, doctors also recommend exercising regularly. But exercise is also a kind of medicine, the overdose of which can harm you. Many people exercise excessively in the name of fitness. Well, people are victims of the side effects of exercise. Anything in excess is bound to have side effects. That is why it is important to be alert and careful even while exercising. In new research, it has been told that excessive physical activity leads to the deposition of calcium on the arteries, which increases the risk of heart disease, that is, Cardiovascular disease. However, the benefits of exercise have also not been denied in this study.
Regular exercise can help prevent diseases like obesity, diabetes, and heart attack. Researchers from the Sungkyunkwan University of Medicine in South Korea and Johns Hopkins University Bloomberg School of Public Health in America did the research. The international team of researchers reported that Coronary atherosclerosis could also occur due to mechanical pressure and injury to the blood vessel wall and physiological response in conditions of excessive physical activity. It increases blood pressure as well as increases the level of parathyroid hormone.
Parathyroid hormone, also known as parathormone. It is secreted by the parathyroid. It controls the concentration of calcium serum in the bone, kidney, and intestine. Another dimension of exercise increases CAC (coronary artery calcium) levels without exacerbating cardiovascular disease. CAC is used as a guide in the treatment of heart attack or stroke. Exercise improves the effect of diet, vitamins, and minerals.
How was the research done?
Researchers conducted a study on 25,485 adult healthy individuals. Their average age was at least 30 years. These people regularly visited two major health centers for checkups from March 2011 to December 2017. On studying them, researchers found that people who were more physically active or exercised more are more prone to old age. Also, a good thing was seen that they had less desire to smoke than people who were less physically active. They had low cholesterol levels but had high blood pressure with calcium deposits in the coronary arteries.
Researchers also observed that the level of physical activity was correlated with coronary artery calcification over time. There was no effect on the CAC score at the start of the monitoring period. Researchers say this was an observational study. Therefore it cannot be included as a definite cause. It is also acknowledged that there was no accurate scale assessment of physical activity. It was also said that there is no data available on the incidence of heart attack or stroke based on CAC density or volume.
What should be the exercise limit?
Researchers say that people cannot question the benefits of exercise on the cardiovascular system. In this case, 150 to 300 minutes of vigorous-intensity or 75 to 150 minutes of vigorous-intensity exercise per week is recommended. However, monitoring for the elevation of coronary calcium levels should also be done.
