Athletic genes are just one factor for success

Connor Svab, a local baseball standout at St. Bernard’s, is in many ways a baseball paradox. In addition to playing infield and pitching, he also plays varsity basketball. At 5-10, 140 pounds, he does not seem to possess the physical prowess valued by many professional teams.

Nevertheless, Svab has gotten the attention of scouts and will be heading to Castleton University to further his baseball career. Interestingly, both his father and great grandfather played professional baseball.

Scientists in the field of evolution have constantly raised the question of nature versus nurture. The arguments in favor of both approaches to development are most prominent in the field of sports. Are some athletes destined to reach great heights from birth or is greatness the product of hard work and opportunity?

Genes are the foundation of heredity. They contain the recipe for the production of proteins that make up the human body. Each person has two of each gene, one contributed by each parent. Those contributions produce our physical characteristics.

Brain growth also plays a prominent role in how a human develops. Specifically, the brain consists of a variety of networks that pass information to different areas within the brain. A brain cell is made up of a cell body and an elongated axon. The axon gradually becomes encased in an insulating material called myelin. Signals are transmitted along the myelin. Brain development is a dynamic process that spans through childhood and adolescence.

The maturation process includes making the brain operate more efficiently. It does this through a process of neuroplasticity. The brain eliminates some networks while making other regions of the brain operate faster and more precise. This can involve motor as well as sensory functions and result in rapid decision-making and reaction to a particular situation. This obviously can be a huge advantage in sports. It is believed that environment plays a big role in this phase of development. 

Lengthy discussions and analysis that center on baseball may have played a big role in the baseball development of Connor Svab.
