Abstract des Autors

Judo, karate, and self-defense are combative activities, each to them consists of attacking movements such as striking, kicking, pushing, or pulling and of denfensive movements for blocking the attacks ((Cooper et al. 1982). In a classification of jiu-jitsu movements the exercises and the break-falls are included. There are breacking tricks and there are practical application of the throws and holds and combination tricks as the self-defense against a knife or a club or a gun or a blow with a fist (Nakae, Yeager 1958). Interest in utilitarian character of the jiu-jitsu, the inclination to the movement activities in the organised forms, self improvement (in terms of fitness, self-control, perseverance and ethics of self-defense proportional to the degree of danger) have helped to increased the popularity of this Japanese discipline in Poland (Sterkowicz 1991). Several studies have been carried out in which the motor fitness characteristics of martial artists are considered (Birrer et al. 1988, Claessens et al. 1986, Hirata and Mori 1967, Shaw and Deutsch 1982). However, motor fitness studies of the jiujitsukas are unknown. The aim of the paper is to evaluate the motor fitness of the trainees of the jiu-jitsu. Verf.-Referat
