In an editorial, two authors noted that the results of one study prove that the health benefits of exercising too intensely are not always the best.. Experts also noted that this study tells about the required duration and established intensity of physical activity at certain stages of a person’s life..

The first analysis was carried out by German scientists who, over the course of ten years, assessed the intensity and frequency of physical activity of more than a thousand people with permanent heart disease..

The volunteers were in their 60s and were participating in a heart health recovery program.. Currently, heart patients are advised to do an hour of moderately intense exercise at least about five times a week..

Of all the participants, the most physically inactive people were twice as likely to develop a heart attack or attack, as were those who exercised excessively strenuous exercise every day.. In a second study from Sweden, more than 44,000 aged 45 to 79 were asked about their exercise habits at ages 50, 30, 15..

It found that men who exercised more than 5 hours a week were more likely to develop an irregular heartbeat by age 60..
