Marlon bj (Marlon bj. Sudden death of young athletes (J). Circulation, 1982, 62: 2 18) defines sudden sports death as non-traumatic death that occurs within 6 hours or immediately after exercise. At present, most scholars tend to limit the time of sudden death to 1 hour, such as Chris cm (Chris cm. The role of stress in Dickas's heart attack. Physicians and sports medicine, 1989 (1): 40) think that it is during exercise or within 1 hour after exercise stops, and Goldstein [28] also thinks that sudden sports death refers to death within 1 hour after the onset of symptoms; There are also scholars (Tang Pei, Exercise and Sudden Death (J), China Journal of Sports Medicine.1990; 9 (1): 3 1) Accidental death during or immediately after exercise is called instantaneous death, and accidental death within 24 hours after symptoms appear is called sudden sports death. At present, there is no unified definition of the time range of sports sudden death at home and abroad, and most of them are determined according to their respective purposes, so the time ranges from 30 seconds to 24 hours, which is not conducive to the development of sports sudden death research. According to the definition of sudden death in medical field and the occurrence of sports sudden death, sports sudden death is defined as non-traumatic accidental death during exercise or within 24 hours after exercise. origin
The first recorded exercise-induced sudden death in human history can be traced back to 490 BC. That year, the Greek army launched a fierce battle to determine the fate of Greece in Marathon, a military town near Athens. After the Greek army won a great victory, the young soldier Phidippides was ordered to run back to Athens to report the good news of victory. However, when he ran to Athens, he just shouted "We won" and fell to the ground and died. In memory of Ferdinand Peters, the "Marathon" was born.

Many athletes died suddenly in sports in history. In recent years, some athletes who have made great achievements in sports have caused a sensation, such as Jim Fix (1984, Marathon, USA), Furong Hyman (1988, Volleyball, USA) and Sergei Glinkov (1988). It is speculated that all these athletes died of sudden cardiac death (SCD). It can be seen that SCD is the most important cause and manifestation of sudden death during exercise.
I believe many people still remember the tragedy a few years ago: June 65438+1October 65438+July 2004, during the 2004 Beijing International Marathon and the 5th Capital University Marathon Challenge, two amateurs-a university student in Beijing (male, 20 years old) and a member of a long-distance running club (male, 64 years old) died suddenly. One year later, on June 65438+1October 65438+June, at the 2005 Beijing International Marathon, another similar scene happened: an amateur (male, 26 years old) died suddenly. Such a similar sudden death incident, coupled with the sudden death incident of athletes that has been heard in the past, not only brings people shock, but also questions: What caused the sudden death of athletes (whether professional or amateur), which has always been regarded as the healthiest group?
