A comparative analysis of male judo and Brazilian jiu-jitsu practitioners based on motor performance and body build

Abstract

Introduction. Particular fighting styles such as jiu-jitsu and judo, despite they have the same roots, differ from each other in technique and fighting dynamics and may involve different physical and functional demands. The aim of the study was to com- pare selected motor performance and body build variables in a sample of male combat athletes. Material and methods. An anthropometric and fitness examination involved 23 judo and 43 Brazilian jiu-jitsu practitioners. The study was performed under the auspices of the Polish Ministry of Science and Higher Education under the grant "Develop - ment of muscle strength among martial arts and combat sports athletes differentiated by body build" (No. NRSA1 001551). Results. While the jiu-jitsu group showed better performance in the standing long jump and sit-up test, the judo group attained higher strength values in which the largest difference was in back strength by approximately 20 kG. No significant intra-group dif- ferences were found in mean body height and size. Greater subscapular skinfold thickness and smaller forearm girth was found in the jiu-jitsu practitioners; the judo group was better hydrated. Conclusions. The specificity of Brazilian jiu-jitsu, in that it allows a number of fighting techniques not permissible in judo, is reflected in improved motor performance via strength of the abdomen and lower limbs. The judo practitioners, using techniques that primarily engage the trunk and upper limbs, present strong back and forearm musculature as well as less trunk fat and increased forearm girth.
