The analysis was done by watching TV monitor several times. Five quantitative factors were tested between weight categories. As the results, no significant difference was found in average obtained point, but significant difference was found in average lost point (p<.05). Average obtained point showed significant difference in cross effect of the type of game and weight category. And average lost point showed significant difference in the type of game (p<.01) and weight category (p<.05), too. The frequency of point by skills of stand and ground wrestling showed significant difference in weight category (p<.001). However, no significant difference was found in frequency of point by time zone among weight categories.
