Objective of the study was to conduct a comparative analysis of morphological indicators determining the competitive success in taekwondo, karate and judo. Methods and structure of the study. Sampled for the study were the 18-25 year-old athletes specializing in taekwondo, karate and judo (n=126), middle weight class, with sports qualifications not lower than I senior rank (main massif), of which 38 athletes - masters of sports, members of the national teams of St. Petersburg, participants of international competitions ("successful" athletes). Their experience in martial arts was on the average 10 years. We measured the following anthropometric indicators of the subjects: body mass and body length, its partial, circumferential and transverse dimensions, skin-fat thickness. The athletes` physique type was evaluated using the Bunak method. Results and conclusions. With the same body mass, "successful" athletes differ from the majority of martial artists by the larger partial, transverse and circumferential body dimensions, as well as by the larger body-weight ratio. The correlation analysis of anthropometric characteristics and sports qualifications revealed the following relationships (Table 2). For karatekas, the significant morphological indicators are as follows: leg and arm length, shoulder and forearm circumference, and the acromial diameter. For taekwondokas - trunk and lower leg length, thigh and lower leg circumferences, and iliopectineal diameter. For judokas - chest, shoulder and thigh circumferences, diameters of the distal epiphyses of the thigh and lower leg. All athletes had a muscular constitutional type; however, belonging to this somatotype is not a prerequisite for achieving a high level of sports mastery in martial arts. The findings can be used as morphological indicators in forecasting the success of competitive activity in martial arts.
