For those unwilling to take the time to read the article I'll paraphrase it.
Athletes are more efficient in the neurons they use. They have this skill because the brain is maleable and when it sends a command it takes into account the response. It improves the efficiency of its commands with each outcome.
Athletes who are more practiced perform better and are better able to anticipate an outcome with only seeing the beginning movement.
Athletes with less experience in practice can only guess what outcomes will be.
"These studies are beginning to answer the question of what makes some people great athletes: They are just able to rewire their brains according to certain rules. As neuroscientists decipher those rules, they may find ways to give people better skills."
They tried out a theory of using an electrode whenever patterning a new skill. Those with the electrode remembered better how to do the exercise after months of not practicing.
It definitely questions what is the future ethics in sport training.
