[Somatotypes of male and female competitive Ju-Jutsuka].

31 men and 10 women of the German national cadre or cadres of the federal states (average age 22.3+/-6.1 years), who practised the still relatively new martial arts sports Ju-Jutsu for 8.9+/-4.3 years with 6.2+/-3.6 h training/week, were investigated by means of kinanthropometric methods and compared to 31 male and 10 female hobby martial arts athletes (average age 29.2+/-7.0 years), who practised Jeet Kune Do, Ju-Jutsu or Wing Chun since 8.2+/-7.8 years with 4.1+/-1.7 training hours/week. In the somatochart after Parnell the fighters were placed more endomesomorphic than the hobby sportsmen. In Conrad's chessboard sample graphics the fighters concentrate on the leptomorph half including the metromorph corridor. Remarkable above all is here a placement of the weight class average values toward the pyknomorph hyperplastic quadrant. Also in Knussmann's body build typognosis the weight classes reveal a clear tendency from the coordinates -13/0.5 to -8.3/6.5 in the superleptomorph area. The body fat percentage varies from 17.4 % (male competitors) to 21.8 % (male non-competitors) and 21.2 % (female competitors) to 23.6 % (female non-competitors), which appears still optimizable in comparison to other martial arts collectives.
