Every Individual comprises of some key factors associated with genetics (acquired or inherited), ancestry (family history) and exposure which may be lifestyle or environmental. During lifetime, various intrinsic (age, gender, diseases) and extrinsic (motivation, resources) factors interact among each other which helps influence the individual’s performance as an athlete. It has been evaluated that genetic variations may be involved for evaluating the performance phenotypes. This is known as sports genomics. The influence of genetics on sports performance of athletes is associated with strength, flexibility, neuromuscular coordination, endurance, power and psychological traits. These traits are inheritable in up to 66% individuals. However, genetic predisposition is also accompanied by epigenetic and environmental factors for athletes to become champions./
