Objective: To analyze the impact of basketball practice on bone mineral density of male adolescents. Methods: 9-month cohort study carried out with 27 adolescents (controls, n= 13 [11.9±2.2 years] and basketball players, n= 14 [13.4±1.2 years]). Bone mineral density was measured in different body segments (upper limbs, lower limbs, spine, and total) using the dual energy X-ray absorptiometry technique. Intake of vitamin D, chronological age, somatic maturation, fat-free mass, and height were adopted as confounders. The statistical analysis was composed of the Student's t-test, analysis of covariance, and Pearson/partial correlations. Results: Regardless of confounders, there was a positive relationship between higher basketball practice time and bone density gains in the upper limbs (r= 0487 [95%CI= 0.131 to 0.732]). Conclusion: The practice of basketball seems to affect bone mineral density gains in adolescents, mainly when the practice is prolonged.
