i'd have to dissagree with that. the reason you might see only girls winning every time is because the boys are uncomfortable about hitting the opposite sex. in teen matches, yes it is more common for the girls to win than the boys because of those awkward hormone problems/ problems with confidence. if a boy can convince himself that the girl is aware of the risk involved with sparring, he can overcome that problem. as for me, i have only lost one match and that was to someone twice me size . maybe im just too competitive, i dont know. maybe its just a matter of skill, but this can alter their performance. a boy must be karate minded in all aspects of his mind during competition to truly remove the handicap. theres my 2 cents.
