Don’t rely on this study as an excuse for not exercising. The British Heart Foundation targets only those who practice marathon or triathlon type training. The foundation echoes a study which shows that in mice, intense physical exertion generates a lowering of the heart rate. This observation would explain why high performance athletes have a slower heart rate. The prolonged physical exercises would indeed disturb the beating of the heart.
Average adults have a heart that beats an average of 60 to 100 times per minute whereas an endurance athlete has a heart that can rise to only 30 beats per minute, or even less at night, since the pauses between two beats can lengthen.
A risk of arrhythmia (heart rate disorder) with aging cannot therefore be ruled out, even if it remains low, estimates the study published in the journal Nature communications. Further studies are needed to confirm this risk.
In the experiment carried out, sport led to a decrease in the protein “pacemaker”, which stimulates the heart rate. It is therefore this drop in the level of the protein that would lead to a lowering of the heart rate.
These considerations are interesting for athletes: “If a slow heart rate in an athlete is not a problem, with age, they would then be more likely to require the wearing of a pacemaker (pacemaker) adapted”, University of Manchester researcher Dr Boyett told the BBC.
Sport is good for the heart
The British are not the first to warn of a excessive exercise for heart health. In 2012, American cardiologists had already marked the field by warning: “Run too fast, too far and for too long years, can shorten your existence “.
You have to know how to keep it right. If you exercise 2-3 hours per week per week, you have nothing to worry about. On the contrary, you train your heart to stay healthy!
