With the development of sports in the world, especially athletes need to start sports at a very young age and be disciplined in order to develop in the sports they do. For this reason, genetic tests are applied to children to determine their predisposition to sports at a young age. Studies on sports genetics are increasing day by day. Genetic factors are directly related to many components known to be important in athletic performance such as endurance, strength, power, muscle fibril composition. Despite the many factors that affect performance in sports, factors of genetic origin can have significant effects on performance. The fact that being able to go beyond performance limits in sports is hidden in the athlete's DNA has made the relationship between sports and genetics important. Some studies examining the relationship between sports and genetics have shown that sports skills can be genetic.
