A lot of "old school" martial art practitioners tend to frown upon the idea of martial arts training as a sport. The reason why they have an attitude like this is that they believe that training for sport undermines the ability to be adept in self-defense. Martial arts is mainly intended for self defense. Keeping this in mind, there's a belief that it's self-defeating to invest time in sportive martial arts training. This is just partly true, though. The reality is that the sportive facet of training can greatly help your ability to defend yourself. You will find quite a number of reasons this is so.
