Evaluation of the effects of emotional and violence-related genes in athletes

Investigation of the human genome involves the examination of many factors such as gene function, structural features of the genome, chromatin arrangement, recombination rate, and mutation to accurately understand its complex relationship with physiology and diseases. With the sequencing of the human genome, there is an increasing number of studies investigating the influence of genes during the development of behavior and personality traits. Studies show that complex behavior and traits are regulated by multiple genes. In this sense, genes that affect the dopamine pathway are studied in relation to the field of neuroscience. Studies on sports genetics include all of the studies in this field, such as the identification of genes that affect athletic performance, the elucidation of the mechanisms of action of these genes, and the determination of predispositions in terms of athletic performance. Considering the factors that determine success in sports, it is of great importance to create training and nutrition programs suitable for genetic structure not only in individual sports but also in team sports. This study will be presented as a review of the associations in the literature about catechol-O-methyltransferase, 5-hydroxytryptamine transporter, and monoamine oxidase, known in the literature as candidate genes that affect the personality and behavioral characteristics of athletes and are especially related to aggression.
