摘要：Background and Study Aim: The recognition of contestants ` body build is essential for search for sports talents. The aim of this work is to determine the age, training experience and age of beginning training and the level of anthropological traits of top Polish ju-jitsu players as joint effect of selection and special training. Duo and Fighting events have been considered. Material and Methods: During the Ju-jitsu tournament anthropometrical measurements were taken for Duo System (n=6) and Fighting System (n=24) contestants. The nation team coach has selected the best contestants for this tournament. The morphological features were compared to those of the non-training students of the Warsaw University of Technology (n=165). Difference significance t -Student test was applied and Cohen’s d was calculated. Results: The Duo group did not differ from the Fight group in age, training experience or the age of taking up training. When directly compared, the morphological features in those groups were similar. Morphological profiles of the contestants with the background of non-involved men in the sporting activity depended however on the practiced ju-jitsu event. Conclusions: Polish contestants are in the optimum age for successes in ju-jitsu sport. The age of their taking up training reflects large differentiation. The men practicing ju-jitsu – with the background of the untrained men – are characterized by a larger body mass shorter and broader hand, larger arm circumference arm, forearm, thigh and lower triceps skinfold breadth. The Duo system competitors – with the background of the untrained men – are differentiated with larger sitting height, foot breadth and fat mass in kg. The contestants of the Fighting system – with the background of the untrained men – have lower body height, arm span, legs length, arm length, and foot length, and elbow and wrist’s breadth. They have also bigger circumferences of shin, lower skin fold of subscapular area, percentage of fat as well as higher fat free mass percentage
