Objective: The purpose of this study was to establish associations between the maximum speed obtained during a soccer match with body composition and bone mass in young soccer players from different maturational groups. Methodology: Cross-sectional study with 175 male soccer players. The velocity was measured by the global positioning system (Polar Team2 -USA). Bone mass (bone mineral density and content) and body composition parameters were obtained by the double-energy x-ray absorptiometry (iDXA-GE Healthcare Lunar, Madison, WI, USA) of the whole body and legs (lower limbs), the mass of (n = 42), During (n = 57) and Post (n = 76) the peak of growth was evaluated by means of this instrument, and somatic maturation was evaluated by the peak of growth velocity. growth rate. Results: Showed significant differences between groups for all variables studied. No significant correlations were found between the variables of bone mass and body composition with speed performance. Although not significant, we observed low coefficients of determination in the different groups: pre (23, 12% for bone density), during (27, 25% for the total lean tissue) and post (24,61% for the percentage of fat and total fat tissue). Conclusions: The results indicate a weak capacity of prediction of bone mass and body composition for the performance of the maximum velocity obtained during a soccer match in maturational groups. However, differences in bone mass behavior and body composition on maximal velocity were observed as the main component for each group.
