Objective: The aim of the present study is to perform a biomechanical quantitative analysis of uniform techniques performed against a real and fictitious target. Methods: The subjects of the study were karatekas (kyokushinkai), a total of 16 experienced individuals. The technical level of the experienced individuals was between first kyu and second dan. The experiments were carried out with the help of video computer equipment for movement analysis. Results: Naturally, in the real hit, at most two maxima were observed, while in the marking one there were a number of (more than 4) local extrema. During real performance, the acceleration path is significantly longer which leads to the need to exert much larger inertial forces. This is probably due to the fact that in the demonstrative performance the competitor fails to use the maximum potential of his explosive muscle forces. Conclusion: The derived characteristic for the number of extrema on the functional curves from the space-time characteristics demonstrates a stable regularity, through which the degree of sports and technical mastery and the objective differences between real and formal strikes in karate can be reliably assessed.
