Two newly published studies have found that prolonged and strenuous exercise may not be as bad as previous studies have suggested.

The first study from Harvard University revealed that people who exercised for 450 minutes every week were 39% less likely to experience premature death. Those who did 150 minutes of exercise weekly had 31% lower risk of early death, while those who exercised for less than 150 minutes a week were 20% less likely to die early.

This came from a survey of over 661,000 middle-aged adults whose results were compared with more than 116,000 death records from the same group.

The second study conducted by Australian researchers examined the degree of exercise of more than 200,000 Australian participants. Researchers then compared the data with the deaths among the participants.

According to this study’s results, participants who met the recommended 150 minutes of exercise had lower risks of early death regardless of how moderate their exercise was. Also, those who occasionally did strenuous exercise had an even lower risk of experiencing premature death.

The results of these studies contradict that of a study from the Journal of the American College of Cardiology published in February this year. In the study, joggers who did more than 150 minutes of exercise every week had a 66% mortality risk. On the other hand, those who exercised for less than 15o minutes a week had the lowest risk of dying early. The older study also found that moderate jogging is better and more beneficial than a strenuous one.
