After the end of Human Genome Project and the establishment of the complete sequence of our genetic code, biologists' interest has shifted to the analysis of variations in non-repetitive sequences present in the genome, the most common single nucleotide polymorphisms (SNPs), and also insertion and deletion polymorphisms. As a rule, these polymorphisms have no effect on cell function, however many of them are highly related diseases and the influence of drugs on the cellular response. Furthermore, the study of these polymorphisms can be used in various fields of biomedicine, pharmacology and medicine in sport for the study of physical fitness and inflammatory processes. According to recent studies, several polymorphisms of the genes related to muscular, cardiovascular system and cellular metabolism affect the efficiency of expression or the protein encoded by these genes, resulting in greater or lesser ability to exercise and muscle injury. Many of these changes were more prevalent among practitioners of a particular type of exercise or even prevalent in people with higher level injury or exercise intolerance. In order to obtain a genetic tool as an indicator of physical performance for athletes and non athletes from Brazil, the project aims at validating the genes related to physical performance and muscle injury through genotyping of athletes of today and past.
