Karate techniques are characterised by a high precision and high movement velocities. The purpose of the training is to optimise the punch and kick techniques in order to achieve a high level of performance. Particular attention is paid to shotokan-karate kumite. Kumite-karate is characterised by two active athletes fighting against each other in a certain area (DKV, 2008). Regarding the situation of publications in karate, there are analyses concentrating on physical education (e. g. Lehmann & Jedliczka, 1998). But only a few biomechanical technique studies can be found (e.g. Nakayama, 1986, Zehr et al., 1997, Sforza et al., 2000). One possible reason is the high measuring requirements. The aim of this study is the presentation of first biomechanical researches in relation to specific developed measuring stations to get knowledge and understanding about the movement structure and the specifics of a punch and several kicks. Three complexes were processed: - Biomechanical analyses of Gyaku-Zuki, - Movement structure and comparison of several kicks, - Biomechanical modeling for a kick movement and step-movements to estimate the joint loads.
