Abstract

The aim of this study was to quantify the difference between two different karate performances in Tsuki techniques from waist and from midway, in classic and individual styles. Eleven female karateka, with different levels of training and knowledge of karate were volunteered to our study and filmed with two cameras at 250 Hz. This allowed the two dimensional reconstruction of the movements of selected body landmarks. Five landmarks (shoUlder, elbow, wrist, upper-right and upper-left fist) were analyzed, while performing Tsuki. For each karateka and punch, the average time of execution was calculated and the standard deviation of each of two special coordinates X and Y were computed for each landmark. A total standard deviation of the single karateka and punch was also calculated. Through the analyzing we achieved the kinematic and kinetic parameters of each karateka. By the comparison of the different styles and performances, remarkable results have been achieved.
