However, it is undeniable that the probability of sudden cardiac arrest will greatly increase when people engage in marathon or sexual activities.
The more we run, the stronger the intensity, the stronger the heart will become, and the larger the size, so as to better transport the blood to the muscles being exercised.
It’s just that the myocardium becomes stronger and the atrium and ventricles become larger.
They are compact and attractive.
It’s not a sign or trigger of heart failure.
Netizen: they are so beautiful.
What effect does running have on the heart? The process of exercising the heart is very similar to that of exercising the muscles.
This ability to dilate makes it easier for blood to bypass small blockages in arteries—— Wider, more capillaries branch down the coronary artery, and there are many capillaries that carry blood to the heart.
Before discussing the new findings, let’s take a look: what is the difference between a person who often runs and an ordinary person? (* the blue dotted line in the figure shows the hearts of ordinary people, and the black part shows the hearts of endurance athletes.)—— Athletes engaged in endurance events with a larger overall outline can have a heart size of up to 50% larger than that of ordinary people—— The larger atrium is the upper two cavities of the heart, responsible for receiving blood from other parts of the body to the heart.
If you run for a long time, your atrium will enlarge.
However, the latest research results show that at least these changes are harmless.
For runners, the coronary artery usually has better flexibility, so that more blood can flow into the heart during exercise.
People who often run have more capillaries, which may be two to three times the size of ordinary people who do not run.
The most important reason is that the marathon was not a national sport at that time – in 1975, only 16000 people completed the whole marathon in the United States.
Low heart rate also has little to do with arrhythmias – in fact, arrhythmias are more common among non runners.
In the long run, people who are always running marathons are not as healthy as those who are light-weight runners.
In other words, as the human body becomes more and more adapted to marathon, as more and more people know how to prepare for marathon step by step, this conclusion may be reversed* Part of the material comes from the Internet.
Don’t be surprised, there are quite a few researchers who hold similar views abroad.
It is precisely because of this numerical comparison that these studies have become meaningful.
Obviously, running is not a chronic suicide, it will have many benefits to our body.
Last year, it was nearly 500000.
It makes sense! “Safety first” is also applicable to running! After 1996, Hainan beauties became “popular” because of their morning running photos.
Take the United States as an example.
The runner’s heart is enlarged.
But the researchers are very serious about the point that every time they run a marathon, the limit of the heart will be pushed up a little.
After all, running does change people’s heart, and whether this change is good or bad is really hard to prove.
Of course, the link between running and heart problems is also due to the increasing frequency of sudden death in marathon races.
The real meaning of running is: external training, internal training! If you run in winter, you will get frostbite if your posture is wrong! Are you here to run or to install B? Welcome to share your horse running story and the bits and pieces on the road! Comments: 993851252@QQ.com I really liked everything you ordered..
However, another important conclusion mentioned in this investigation report is that in the sudden death events of running in the United States in the past few years, most of the people involved have undiagnosed heart problems, such as myocardial hypertrophy.
At the same time, if you exercise step by step to make your heart stronger, the foundation laid by running can have many positive effects on your body in the 23 or 22 hours you don’t exercise in a day.
However, this is not a judgment of “from cause to effect”, but a conclusion based on the data of the past decade or so.
Similarly, the volume of the two ventricles in the lower part of the heart, which are responsible for delivering blood, will also increase with the increase of running—— Softer coronary artery the coronary artery is the artery responsible for supplying blood to the heart.
40 or 50 years ago, the absolute number and proportion of sudden death events were incredibly low.
Recently, scientists have made new discoveries.
Is running good or bad for the heart? This topic has been debated for more than a century.
After understanding the difference between the hearts of ordinary people and runners, I believe many people have heard the view that “running is equal to chronic suicide”.
If you invade or delete the wonderful recommendation of “ugly people”, you need to exercise more.
In the words of the researcher, “after so many years, we finally have enough runners who regard running as their life as a research sample.” Logically speaking, doesn’t this just verify the physical damage of Marathon to ordinary people? If your heart doesn’t get exercise at ordinary times, but suddenly takes part in this kind of intensity competition, that’s true.
