Aerobic exercise is a medicine. Doctors warn of the possibility of overdose

For most people, the benefits of aerobic exercise far outweigh the potential risks. But scientists warn that too much stress can be dangerous for people who are not ready for them.

For most people, the benefits of aerobic exercise far outweigh the potential risks. But scientists warn that too much stress can be dangerous for people who are not ready for them. They can increase the risk of sudden cardiac death, dangerous arrhythmias and heart attacks. This is stated in a new statement by the American Heart Association.

“Exercise is medicine and there is no doubt that both moderate and vigorous exercise are beneficial for cardiovascular health. But, as with any medication, insufficient doses and overdose of exercise are possible. Bigger isn't always better,”said Barry A. Franklin, professor at the University of Auckland's William Beaumont School of Medicine, and co-author of the statement.

Franklin added that excessive exercise is dangerous for inactive or untrained people with heart disease - diagnosed or unknown.

“More and more people are running marathons, participating in triathlon and doing intense interval training. The purpose of our statement is to soberly assess the benefits and risks of such intense exercise programs,”he explained.

Scientists have analyzed over 300 studies. They found that for most people, the benefits of exercise are much higher than the risks. Physically active people are much less likely to suffer from heart attacks and sudden cardiac death. But the authors also discovered potential dangers.

The authors of the statement noted that the number of acute heart problems among participants in marathons is growing, which indicates an increase in the popularity of this sport. Among triathlon participants, cardiovascular accidents occur in 40% of cases in beginners. This shows inadequate training or concomitant heart disease, scientists point out. Their analysis also showed:

· Half of cardiovascular accidents happen in the last kilometer of a marathon or half marathon. Therefore, it is recommended to take a responsible approach to the selection of the pace of running.

· The risk of heart attacks is greater if the activity is held high above sea level. But the risk can be reduced by acclimatizing in advance.

· The risk of ventricular fibrillation (a dangerous arrhythmia) is reduced with moderate exercise but high with a sedentary lifestyle. People who exercise too much, such as running over 100 kilometers a week, are almost as at risk of arrhythmias.

The American Heart Association recommends that people who want to be physically active gradually build up from light to more intense. If this does not cause pain and heaviness in the chest or severe shortness of breath, medical advice is not required. But it is necessary for people who have a diagnosis of any kind of heart disease.
