Thanks for all your comments, are perfectly logical and common sense. Because I do not know English well and there are many nuances, I'm limited. But let me explain the situation a little bit more. It's a real and very interesting case, repeat, a real case. Mathematics says a lot in this case, my opinion. In fact, it's only about taekwon-do and kickboxing. I know 2 schools for children under 14. Respect both taekwondo and kickboxing, 2 very attractive sports, taekwondo seems more complete. Children are trained by the best coaches, very very good. It's also about the rules for each sport, when you get to the competition, about how to score. However, attention: if there are 10 battles on kickboxing rules, then the score is 10-0 for kickboxing. If the rules are for taekwon-do, then the score is 9 -1 for ... kickboxing. It is a real, concrete experience. Or to explain otherwise, if I took 10 kids from kickboxing and would go with them to the National Taekwondo Championships, I would probably win 8 gold and 2 silver medals, without these kids making an hour of taekwondo. Kickboxing children are more direct, attacking the head, dominating the fight clearly, and children doing taekwondo are too small, like age, do not have the necessary wisdom to know and use the advantage of foot techniques and ring-to-speed movement. You excuse me again with English. I'm interested in taekwondo in the future at international level, the world's top title, many years in a row. When I see these things, how not to think about kickboxing lessons??? Many taekwondo supercampions also kickboxed and boxed and went to pointfighting contests to gain experience and dominate the fight clearly. Two more real facts. One kid do both tkd and kickboxing. At first, the tkd child was defeated by four kickboxing children, even younger in age and weight. After 9 months, the score is 4 - 0 for him. At tkd competitions he usually was defetead in the first round. At the last tournament he won the gold medal, a international one, 5 wins out of 5, a total of 32 tkd children. Is it that kickboxing 9 months did not matter at all??? Indeed, there is another thing, it could be, after 14 years, when the tkd children will grow up and think of the fight, they will know how to use the higher speed, the combinations of legs as it should, their chances will increase, then they could equal or lead the score. But until then I believe, life has proven to me, that at a great level you need to be polyvalent, to know more than the other. We love Taekwondo ITF very much and we want exceptional results in the future, but we also need good advice. However, life clearly shows the direction in which we must go, the results speak. We have to be one step ahead of the others.Thank you very much!
