Contrary to parents beliefs of karate being a sport is folklore. There are no such thing as a child in karate training. Any good or sufficient martial artist will tell you that the only thing karate techniques does are mainly three things - Cripple, Maime, or kill. Therefore, those are attributes you don't teach to a child unless you also add the other related attributes of which one of them is reasoning. Reasoning refers to the process of drawing conclusions or inferences from information.
Reasoning always requires going beyond the information that is given (Bruner, 1957). In logic, an
inference is called deductive if the truth of the initial information (or premises) guarantees the truth
of the conclusion. The inference is called inductive if the truth of the premises makes the conclusion
probable but not certain. Distinctions between deductive and inductive reasoning can be important
in understanding logic; but in practice, these distinctions may exist more in the mind of the
researcher developing a task than in the performance of examinees on that task. Many researchers
have found that performance on deductive and inductive tests is strongly related (Wilhelm, 2005). I don't believe no child can truly obtain the attributes of reasoning until they experience the information they receive and understand it. Therefore, when we train a child in karate we have to place them in an atmosphere far beyond their mental grasp, namely "Adulthood". We have to teach reasoning to children as well as adults. Which everyone can agree that "Reasoning" is an adult attribute.
Parents ask "Will my child get hurt?" Well, that's all karate does, we hit each other, practically everyday! At some point you're going to feel the pain. Why would you spank, or should I say hit your child, if you didn't expect some level of pain to exist or be created? Your child's efforts in avoiding that spanking, or getting hit is what karate does. Except in that case, the child doesn't hit back, or shouldn't. So, Karate is training and strategy designed to avoid pain from an aggressor and returning that pain ten fold back to the aggressor. Safety equipment is virtually useless in karate training except for incidental contact from falling or bumping into objects. Karate techniques generates enough force to break bricks and boards, so why would you feel a one inch piece of foam is sufficient enough for protection? Your real protection comes from your karate instructor's ability to properly train
and condition you.
