My specialty is Taekwondo, and I belong to the students of the Heavy Physical Education Teaching and Research Section. This semester, I took professional courses focusing on competitive direction, including taekwondo, karate, judo, wrestling, boxing, fencing, fitness and weightlifting. 8 class hours for each event, plus 3 years and 24 credits for Taekwondo. It should also be a preliminary understanding of fighting projects. In fighting events, rules have a decisive influence on skills and tactics. A slight change will give birth to many new training methods and a large number of papers on new rules ... Therefore, any fighting event can not be divorced from the rules. Broadly speaking, free fighting is not free. Furthermore, the so-called heavy competition refers to the classification of competitive events by kilogram (fencing, fitness and weightlifting do not belong to heavy competition, but belong to the heavy competition teaching and research section of our school. So it's unfair to fight without considering weight. To sum up, it is more than enough for professional female athletes to compete against male amateur athletes when the rules and weight are relatively fair. Some time ago, Taekwondo won the first commercial competition, and a certain kilogram champion was Wu Jingyu's sparring partner. Regardless of the rules and the severity, people have different opinions, and no one can draw a clear conclusion.
