Why do Jamaicans run fast?

Before the Beijing Olympic Games, Jamaica won 44 Olympic medals, most of which were individual sprints and relays. In the Sydney Olympic Games in 2000, Jamaicans won two gold medals, which tied their best results in the 1984 Olympic Games, among which the fast woman Campbell won two gold medals in the 200m and100m relay. Among the 5 1 Jamaican track and field athletes who appeared in the Bird's Nest in Beijing Olympic Games, 39 were sprinters. Bolt, who is genetically superior, has become the fastest runner in the world, but his height of 1.96 meters is not suitable for running 100 meters. Bolt practiced 100 meters less than 1 year. In his own words, practicing 100 meters is a special training to improve the future explosive power after he finished second in the 200 meters at the World Championships in Osaka last August. A decision created a new "flying man". Why does God favor Jamaicans so much? Scientists from the University of Glasgow and the University of the West Indies conducted a study on more than 200 Jamaican athletes, and found that 70% of them have a substance called actin, which can improve muscle fibers related to instantaneous speed, and these muscle fibers can make athletes run faster. However, only 30% of Australian track and field athletes contain actin. "The advantage of Jamaican sprint is not a flash in the pan. There are many Powell or Simpson there, which is determined by genes. " Researcher Morrison said. 5-year-old competition In Jamaica, sprint has become a popular sport, and boys and girls will participate in national competitions when they are 5 years old. "When Bolt played, all the neighbors came to my house to watch the game, and there were more than 100 people inside and outside. Everyone waved flags, beat gongs and drums, and cheered. /kloc-the 0/00 meter final will be held in the local morning, and the whole of Jamaica will celebrate him all day. " After Bolt won the championship, his father, Old Bolt, talked about Jamaicans' crazy about sprinting. Jamaica is rich in sprinters, but their training conditions cannot be compared with those of Europeans and Americans.
