Some sports are actually an art form of self defense and getting the upper hand in a situation. With martial arts there is a tremendous technique of strength, balance and quick movements. You have to anticipate what the other person is going to do ahead of time and be prepared with defensive moves. It takes years of training and practice sparring with a partner to be ready with opposing maneuvers. The main idea is to avoid injury to yourself and stopping the opposition from rendering you helpless as well. Watching these athletes in action it seems there are almost dance moves and acrobatics as they change from one stance to another in a fluid set of movements. They learn specific moves the same way dancers learn different sets of steps.
There is a systematic approach to pinning an opponent down during a competitive match. The method doesn’t depend so much on size and strength but on getting the upper hand. You learn how to take down your opponent by knowing strategic moves like leg dives. With Grappling you need to be ready with quick moves to escape being pinned down. The best offense has always been a good defense, and the object is to get the upper hand without an injury to either contestant. It is a match of persistence, quick movements and trying to out guess what type of movements you are up against. You can learn special holds and arm locks as well as escapes and reversals to put you back on top.
