Genetic Predisposition or Determinant: Is there a role of Genetic Influence on Athletic Performance specifically to young athletes?  A favorable genetic profile when combined with an optimal training environment, is important for elite Athletic Performance; However, few Genes are consistently associated with elite Athletic Performance and none are linked strongly enough to warrant their use in predicting athletic success (Guth et al, 2014)
Every sport has unique physical requirements and these requirements can be dramatically different between sports, so, genetic influence on performance must consider the performance components most appropriate for the specific sport of interest.
Considering the number of body systems, including; nervous, musculoskeletal, cardiovascular, respiratory, etc. that must interact, at heightened states, athletic performance is one of the most complex Human traits (Tucker 2012).
So, regardless of body Morphology, Endurance, Strength, and Power - which are factors underlying Athletic Performance; Does specific Genetic influence determine Athletic Performance? And, if so; How much of a role does it play?
