In biomechanics, systems in motion — such as the impact of a ball on a player’s head — are described or “modeled” by mathematical differential equations. For example, these equations can show the relationship between the acceleration or force of the ball to the head at impact, and the change in shape of brain tissue in response to that form. The solution to these equations provides information that could be used to establish new safety regulations or adequate sports gear for players.
Current studies show that heading the ball may not be as much of a concern as physicians and parents thought, although it is not fully understood how repetitive head shooting, through many years of play, affects players. Further research will continue to help treat and prevent injuries, and improve athlete performance through individualized coaching.

Human genetics can play a major role in determining an athlete’s potential. Genetic information is passed from parent to child and is stored within human cells in the form of DNA (deoxyribonucleic acid). An individual’s DNA influences attributes such as height and weight and can help to determine if an individual has a predisposition towards athleticism. Genes play a major role in body type and athletic ability, but an athlete must also work hard to realize his/her potential.
