The vast majority of scientists agree that physical activity and morning exercise useful for human health. At the same time, professional sport has in this respect. much more mixed reputation. A group of experts from the U.S. and Germany has found indirect evidence that men in the triathlon can thereby harm his heart.
Triathlon is a race consisting of three successive phases – swimming, Cycling and running. It is believed that the rules of such competitions were held little less than a century ago in France, and the concept of triathlon in its present format began to take shape in 1934. The distance for each of the three stages in each case are determined by the organizers.
The research assistants collected information on 55 men and 30 women who are professionally engaged in triathlons or have had a career of an athlete behind. Ten men (18 per cent of the total) in the left ventricle of the heart, which plays a key role in pumping of blood, was discovered microrubra. Interestingly, none of the women they observed. According to experts, the more active the athlete preparing for competition and the long distances he had to overcome, the higher was the likelihood of scarring and the more noticeable they were.
Experts note that while the influence of these scars on health it is impossible to say with certainty, however, there is a possibility that they increase the likelihood of developing arrhythmia, or even heart attack risk.
Also, scientists are not ready to give a definite answer to the question why the trend is noticeable only amongst men, but make the assumption that a certain role in the formation of scarring may play testosterone, which in the male body much more.
