SUMMARY:

Regarding the selection of talents in jiu-jitsu, it is necessary to take into account which factors can affect sports performance, such as morphological characteristics and biological maturation; thus, the study aimed to relate biological maturation and anthropometric components with the muscular strength of young jiu-jitsu athletes, as well as verifying the effectiveness in correctly discriminating these athletes. A cross-sectional study was carried out with a sample of 18 young males (13.0 ± 2.20 years). Neuromuscular tests of upper and lower limbs and assessments of body composition, biological maturation, and anthropometric variables were performed. In both groups, biological maturation and anthropometric components were related to upper and lower limbs strength (p <0.05); discriminant functions pointed out that biological maturation (F = 3.59; p = 0.03) and the height of the trunk (F = 3.85; p = 0.01) can discriminate the upper limbs strength by 98.0%, while the length of the legs can discriminate the vertical jump (F = 6.92; p = 0.01) and countermovement jump (F = 6.90; p = 0.01) by 96.7%. Artificial neural networks indicated that together, anthropometric components and muscle strength discriminate 93.5% of Brazilian Jiu-jitsu athletes and 94.8% of the control group. Thus, biological maturation and anthropometric components are related to the performance of upper and lower limbs muscle strength of young elite jiu-jitsu male athletes, as well as maturation, trunk height, and lower limbs length are discriminating factors for the performance of upper and lower limbs muscle strength in elite young male jiu-jitsu athletes. In addition, lean mass, somatotype, trunk height, span, leg length, and upper and lower limb strength proved to be effective in discriminating young jiu-Jitsu athletes, suggesting the importance of these variables in the selection of young talents in this sport. Thus, the present study allows coaches to assess certain characteristics in young athletes so that they can serve as parameters in the selection of sporting talents in jiu-jitsu.
