The future of tennis training? A quick analysis of this talent map reveals some splashy numbers: for instance, the average woman in South Korea is more than six times as likely to be a professional golfer as an American woman. But the interesting question is, what underlying dynamic makes these people so spectacularly unaverage in the first place? What force is causing those from certain far-off places to become, competitively speaking, superior?So even here, at the core of one of the globe's brightest talent blooms, the question of that talent's source remains enigmatically tangled, perhaps as much of a mystery to those who nurture these athletes as it is to the rest of us. It's enough to make you wish for a set of X-ray glasses that could reveal how these invisible forces of culture, history, genes, practice, coaching and belief work together to form that elemental material we call talent - to wish that science could come up with a way to see talent as a substance as tangible as muscle and bone, and whose inner workings we could someday attempt to understand.However, basketball or tennis sport men, talent is not one main factor cause their super skill raising. Training is one important factor causes their super skill raising. "This is a new dimension that may help us understand a great deal about how the brain works, especially about how we gain skills."Its very inertness is why the first brain researchers named their new science after the neuron instead of its insulation. They were correct to do so: neurons can indeed explain almost every class of mental phenomenon-memory, emotion, muscle control, sensory perception and so on. But there's one question neurons can't explain: why does it take so long to learn complex skills?"Everything neurons do, they do pretty quickly; it happens with the flick of a switch," Fields said. "But flicking switches is not how we learn a lot of things. Getting good at piano or chess or baseball takes a lot of time, and that's what myelin is good at."To the surprise of many neurologists, it turns out this electrical tape is quietly interacting with the neurons. Through a mechanism that Fields and his research team described in a 2006 paper in the journal Neuron, the little sausages of myelin get thicker when the nerve is repeatedly stimulated. The thicker the myelin gets, the better it insulates and the faster and more accurately the signals travel. As Fields puts it, "The signals have to travel at the right speed, arrive at the right time, and myelination is the brain's way of controlling that speed."
