The kinematic variables of a 4 techniques of karate (including Maei Geri, Zenkutsu Dachi, Zoki, combined technique of Zoki and Zenkotsu Dachi) were studied and compared in two groups of top-expert and practiced karate kas. The subjects included 9 members of the national team and 7 karate kas with at least 6 years of experience. The measurement was conducted using stereo-videography and the 3-D coordinates of the reflective markers attached to the anatomical landmarks were traced during motion. The statistical analysis was performed using independent sample T-test for comparing groups mean and pair sample t-test for inter group comparison. Results indicated well observation of some details of the motion pattern by top-expert group. Also, comparison of the standard deviations of the variables between the two groups revealed that the motion has been conducted with a higher degree of similarity within the top-expert group.
