Study: jogging too much is life-threatening

Exercise in moderation is healthy, but if you overdo it with physical fitness, you live dangerously. This is the conclusion of an analysis by the Copenhagen City Heart Study. Peter Schnohr from Frederiksberg Hospital has been accompanying a sample of residents in the Danish capital since 1976. In 2001 they were asked, among other things, whether they jog and, if so, for how long.

Schnohr compared the data with the deaths since then. The result is a U-shaped curve that shows the lowest mortality rate when jogging 2 to 3 times a week for a total of 1 to 2.4 hours. The optimal speed is 8 kilometers per hour. According to the study, those who jog for a long time or constantly push their limits when running can stay away from it. His risk of death in the study was just as high as that of people who never jogged.

The study is an epidemiological finger exercise, the results of which, as always in prospective observational studies, are not necessarily suitable as a recipe for lifestyle. The main objection is reverse causality. It is conceivable that some people avoid jogging because of chronic illnesses. The illness and not the lack of sportsmanship would then be responsible for the increased risk of death.

The real essence of the study could be that too much agitation in sport is not necessarily healthy: Aggressive jogging can be a continuation of work stress by other means. The chronic activation of the pituitary-adrenal axis is likely to be unhealthy in the long run. A relaxed run in the fresh air can't hurt, however.
