It is well known that esport is good for health. All specialists recommend it in order to strengthen the human body, to prevent certain diseases and even to promote healing. In recent years, sport has been adopted by the population positively. Some experts highlight the transformation that has occurred in the majority conception about sport, which has grown from an elitist conception prevailing for several decades to a popular conception.

But sports, especially when practiced intensively, may involve some risks. And just as the practice of sport is becoming more widespread, concerns about the risks of practicing it are also growing. News about young people and athletes that after performing an exercise die suddenly do not go unnoticed. Sudden death, as its name suggests, is rapid and unexpected and occurs in apparently healthy individuals. The loss of vital functions happens instantly or within a short interval of time from onset of symptoms. Sudden death is the time after the final "crescendo", when the heart goes into ventricular arrhythmia and rhythm becomes completely uncontrolled until it suddenly paralyzes. Without heartbeats, no blood is sent to the body and the brain is deprived of oxygen. If the situation is not restored within ten seconds, the person can faint, and if the pulse is not recovered in ten minutes, the person can die.

88% of sudden deaths in people over 35 yearsold are caused by the existence of a coronary artery atherosclerosis that in case of an effort and due to the increase of circulating catecholamine causes myocardial infarction and/or arrhythmia. This sudden death is more likely to occur in the presence of abnormal heart rate profiles during exercise and recovery. In people younger than 35 years old, most sudden deaths are caused by congenital diseases such as hypertrophic cardiomyopathy. This disease is especially significant in athletes. When the heart muscle is subjected to apermanentovertraining,we talk about the athlete's heart syndrome. The heart muscle, like any other organ in our body, undergoes changes to adapt to the physiological requirements of the moment. Many of them, when training is maintained for a long time, produce permanent changes that only return over many years, as in the case of professional athletes and those fans with high dedication.

Thus, practicing a sport is as important as knowing how to practice it healthily and well dosed.The project S2-Salut&Sport tries to make an approach in this field to assist in the realization ofhealthier sports.
