RESUMO

Adolescents federated to basketball have an increasing demand for physical, technical, tactical and endurance training. At puberty, environmental and physical factors, associated with musculoskeletal structures immaturity may alter muscle strength, balance, mobility and joint flexibility, as well as influence the posture development. In an attempt to know and understand the consequences of sports training, studies have assessed the qualitative approach; however the means of assessing the posture statistics were not reliable or reproducible. The purpose of this study was to evaluate quantitatively the postural changes, the mobility and the flexibility presented in adolescents federated tobasketball. The study included 74 healthy adolescents, divided into two groups: athletes federated to basketball (AG) (n = 36) and A control group (CG) (n = 38). The quantitative postural analysis was performed by photogrammetry measured using the Postural Assesment Software (PAS/SAPO) and markers previously placed on bone references. The postural variables analyzed were head, shoulder, scapula, thoracic and lumbar spne, pelvis, trunk and lateral inclination of the spine. Goniometry was performed to evaluate the mobility of the upper limbs and the testing of the 3rd finger to the ground to assess flexibility. The data was analyzed by descriptive statistics (average, standard deviation) and Ancova to check the influence of the explanatory variables in the independent variables, by adopting the equal to 5%. In the frontal plane, athletes had greater lateral inclination of the spine (AG = 5.0° ± 2.4 and CG = 3.7° ± 1.6) and in the right sagittal plane they had lower values for the head (AG = 51,4° ± 5.3 and CG = 48.6° ± 5.62), pelvic anteversion (AG = 11.4° ± 5.9 and CG = 14.5° ± 5.1), vertical alignment of the trunk (AG = -0.76° ± 2.8 and CG = 0,7° ± 2.6) and thoracic kyphosis (AG = 27.9°± 7.0 and CG = 32.9° ± 7.5). In the left sagittal plane the athletes had lower values for the anterior head (AG = 52.5°± 5.7 and CG = 46.4° ± 5.6), protrusion of the shoulder (AG = 5.9 cm ± 2.2 and CG = 8.3 cm ± 2.1) and pelvic anteversion (AG = 10.2° ± 6.1 and CG = 14.6° ± 4.3). The variables in the postural frontal plane (shoulder alignment and posture of the left scapula) were influenced by age. The index of asymmetry of the horizontal scapula was influenced by the height and the left lumbar lordosis suffered the intensity of dominance. As for mobility, the athlete group showed higher amplitude with statistical significance for the movement of the shoulder (flexion L, extension R, adduction R / L), elbow (hyperextension R and L), and wrist (supination L). It is suggested that the posture and joint mobility are influenced by basketball training thus they should be considered during the basketball training in order to follow the development of young athletes
