They say sport is bad for health

From the journalist's point of view, it may be a brilliant title. Remember the example of the dog and the owner: the fact that the dog bites the owner is not news, but vice versa. And that's what looks like this sport and health issue. We have spent years listening to the need for sports to have good health and now, in reliable research, they have shown that the idea is corrupt.
If it were true, it would have been a revolutionary investigation. But is it so big? Were there no inflated titles? To solve the doubt, just go to the blog of the Hospital Clinic, where the research is explained. The title itself gives enough precision: "Intense exercise can lead to fibrosis and arrhythmias in the heart." There is a difference between active living and intense exercise.
Moreover, the news begins with the recognition of the benefits of moderate physical exercise in the heart and circulatory system. The fact is that having an active life reduces the risk of mortality from cardiovascular problems by 30%.
Below is what most of the media highlighted in the titles, that is, sports can also be harmful. But this only happens in very specific cases, "as a result of the exercise of duration that lasts for years". As they have explained, in subsistence activities (marathon, triathlon, cycling...), the heart has to make an exaggerated effort that seems to accumulate damage. Finally, there is a risk of fibrosis and arrhythmias.
Research has been done on rats. According to the researchers, it is very difficult to conduct such a long term research in people, so they have used rats. The animals were divided into four groups, some with sedentary life and others forced to perform an hour of intense exercise for 4, 8 and 16 weeks. This demonstrated that the rats that exercised more were more likely to suffer alterations in the structure of the heart.
Although more research has been recognized to confirm that the same occurs in humans, researchers have concluded that the results of the study can be extrapolated to people who have practiced a sport of between 20 and 30 years. In addition, they have seen a change in the heart of rats that can explain the sudden death of athletes.
Key to the measure
At a time when background sports testing has become fashionable, it may be convenient to consider research at the Hospital Clinic. In another way, it is clear that the investigation is not as revolutionary as the headlines of last week suggested; after all, as in many other things, it shows that the key is to the extent.
In fact, the following news published on the blog of the Hospital Clinic refers to the consumption of beer and goes in the same line, since drinking in moderation have come to the conclusion that it is healthy, better than not drinking anything.
Therefore, if both investigations are added, it can be said that playing sports in moderation and consuming beer in moderation is healthy, while acting in reverse is counterproductive. Okay, it will be true, but as a title it is not very attractive, or what?
