Marathons prolong life. Or not?

The marathon, according to a new study , can extend life, reports CNN . A controversial statement, let's understand.

In a study, the results of which were published in the Journal of the American College of Cardiology, 138 healthy people took part (women and men - about 21 to 69). All of them were preparing for the first marathon in their life. Scientists deliberately took newcomers. Those who said that they were running for more than two hours a week did not participate in the experiment.

These 138 people were preparing according to the plan for beginners from the London marathon : three runs (in total from 10 to 20 km) per week for 6 months. They were investigated before starting training and two weeks after the race.

It turned out that preparation for the marathon - even with a low load intensity - contributed to a decrease in the pressure and rigidity of the aorta. According to scientists, the “vascular age” of participants decreased by about four years, that is, regular training made it possible to slow down the natural wear of the vessels (and this is an important factor in various diseases). The effect was brighter in senior and slower runners.

Is the marathon itself or preparation for it? How much do they usually run in preparation for this distance?

Where are the money subscribers going

Most Republic materials are available by paid subscription. We believe that this is a good way to finance media. After all, as you know, if you have not paid for reading it, then someone else paid for you to read it. In our case, everything is honest: from your money, salaries and fees are paid to journalists, and they write about important and interesting topics for you.

The key feature of our subscription: your money is distributed between Republic magazines depending on how you read it. If you read the materials of one magazine, then your money will go only to him, while others will not go. That is, you finance only what you are interested in.

Republic uses the Redefine.media subscription. For design, we will redirect you to the Redefine.media website, where you will need to register and pay for the subscription. Authorization on the Redefine.Media website will allow you to read Republic materials from the same device.

A year subscription is more profitable than a month. And if you want to unsubscribe, this can always be done in your personal account.
