According to the literature, the genetic makeup of athletes contributes to their athletic
performance. Athletic performance depends on genetic and environmental factors relating to
the athlete. The study of sports genetics includes extensive research into identifying genes
that affect athletic performance. Psychological factors affect athletic performance and so
dopamine contributes to the determination of that performance. One of the neurotransmitters
of the dopaminergic system is dopamine, which affects the athlete mentally and …

Özet Previous studies have identified that genetic variation is a significant determinant of
physical activity-related behaviors and for sport enthusiasm. Dopamine receptor genes have
been linked to a higher degree of overall physical activity. The dopamine receptor D2
(DRD2) rs1800497 polymorphism affects the brain's dopaminergic system and athletic
performance. However, little research has been done on the connection between DRD2 and
sports participation, and the few studies that have been published are contradictory. This …
