Abstract

The concept that genetic traits are strongly associated with human physical performance has been widely accepted in the last decade. Some studies have shown that certain DNA polymorphisms may be related to sports performance, both in short duration modalities and with a high demand for muscle strength, as well as in long term tests, primarily dependent on aerobic metabolism. DNA polymorphisms are called base sequences that differ from those considered "normal", that is, that they present less frequency in a certain population. Research projects will be analyzed to study the DNA of young athletes in order to elucidate the mechanisms that determine a better execution of certain sports. Genetic studies relate 23 genes capable of influencing the resistance phenotype, of which the Olympic DNA project focuses on two specifically related to physical performance: the alpha-actinin-3 protein (ACTN3) and the angiotensin-converting enzyme (ACE). This project consists of the creation of a biological database for young people between 8 and 18 years old. The main objective of this initiative is to correlate the physical aptitudes of each athlete in order to direct him to the sport in which he would obtain the highest performance. Genetic marker studies confirm that physical fitness is related not only to environmental and nutritional factors, but also to genetic conditions. As is the case of ACTN3 gene polymorphism.
