There is no upper limit to safe exercise. The more there are, the better for the heart and health, according to the largest research ever conducted on this subject.
The World Health Organization (WHO) recommends that the intensity of exercise should be between 150 and 300 minutes a week. Exercise should not be too rare, but you should also not overdo it, it was advised. However, recent research has shown that there is no safe upper limit to exercise, and the more exercise the better for the heart. Therefore, it is a myth that too intense physical effort is detrimental to health (of course in the case of healthy people).
This is indicated by research published by "PLOS Medicine", which covered over 90 thousand. people. The observations lasted 5 years, both men and women participated in the tests. 25% exercised the most. volunteers with the greatest reduction in the risk of cardiovascular diseases, ranging from 54 to 63%.
The effect was slightly smaller in those people whose physical effort was slightly less, i.e. moderate or quite intense. In this group, the reduction in the risk of heart disease was between 48% and 57%. It follows that the greater the physical effort and the more intense the health effects are.
This study challenges the myth that there is some upper limit to exercise that should not be exceeded, ”emphasizes one of the authors of the project, Rema Ramakrishnan, an epidemiologist at Oxford University. Her colleague Aiden Doberty from the same university points out that this is indicated by the largest study ever conducted on the subject. It shows - he adds - that the benefits of physical activity are even greater than we realized so far. This applies equally to men and women, although it seems that women benefit more from strenuous exercise.
Active people not only care about their physical condition but usually also care more about their health. Research shows that those who exercise more often do not smoke, take care of their body weight and do not abuse alcohol. All this translates into better health and an even lower risk of cardiovascular disease.
But for the heart, exercise alone is beneficial. It manifests itself in the fact that the more we exercise and the more intensively, the slower the heart rate is. This, in turn, may reduce the risk of death. (PAP)
