SUMMARY:

Biological maturation and anthropometric components can be determining factors in the neuromuscular performance of young athletes. The study aimed to relate biological maturation and anthropometric components with the muscular strength of young Brazilian Jiu-jitsu athletes and to verify the effectiveness in correctly discriminating Brazilian Jiu-jitsu athletes. A cross-sectional study with a sample of 18 young men (13.0 ± 2.20 years; 50% Brazilian Jiu-jitsu; 50% control). Body composition, peak height velocity, handgrip test, medicine ball throw, vertical jump, vertical countermovement jump, and fifteen anthropometric variables were evaluated. 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. Biological maturation and anthropometric components are discriminating factors for strength performance in BJJ athletes. Thus, the present study contributes to sports science, as it allows professionals in the field to better assess certain characteristics in young athletes so that they can serve as parameters in the selection of sports talents in combat sports.
