Introduction: It is well documented that physical exercise, when adequately prescribed, affects positively the bone growth. However, it is not clear which sport modality has higher burden in the physical growth among pediatric populations. Objectives: To analyze bone mass gain in pediatric populations according sport modality, as well to identify the pattern of the bone mass gain in a cohort of 09 months. Methods: The sample will be composed of 200 adolescents of both sexes (100 in sport group and 100 in control group). Adolescents engaged in sport modalities (soccer [goalkeepers will be excluded of the main analysis], swimming and volleyball) and martial arts (karate and judo). Bone mineral density in different body regions will be the main outcomes: (i) total bone mineral density, (ii) lower limbs region, (iii) upper limbs region and (iv) at low back region. Bone mineral density will be assessed by the Dual-Energy X-ray absorptiometry. Several independent variables will be inserted at main analyses as potential confounders. Expected Findings: It is expected to identify several particularities in the bone mass gain, according to engagement in different sport modalities.
