“…A longitudinal study in healthy adolescents similarly reported positive effects of physical activity on cross-sectional area and section modulus at the narrow neck (22), although this effect was lost after controlling for lean mass. Our data are also consistent with studies in pre-and peripubertal children (23), young adult athletes (24), and late adolescent soccer players (25), in whom physical activity was associated with positive effects on HSA parameters. We found strong positive associations of lean mass with hip geometry, similar to the study by Forwood et al (22), and differences between EAs and nonathletes were lost after controlling for lean mass.…”

“…These findings corroborate previous research, which showed that young people engaged in sports activities have greater muscle mass, bone mass, and height [15][16][17][18] . On the other hand these findings may reflect not only the physiological effects of basketball practice (bone deformities caused by vibrations from the impact with the ground during running and jumping, as well as the stimulation of muscle contraction) 19 , but also the effects of the existing selection process in the sport, i.e., basketball players have more chance of being selected if they are taller and stronger.…”

INTRODUCTIONIn recent decades, the prevalence of osteoporosis has significantly increased, impacting in a significant manner on health care costs worldwide. It is estimated that in 2000, about one percent of all retirement-related non-communicable diseases were attributed to osteoporotic fractures 1 . In adolescence, the occurrence of bone fractures is a common event 2,3 , however due to trauma, not osteoporosis. In fact, there are cases of osteoporosis in childhood and adolescence, but the condition is very unusual 4 . About 70% of bone phenotype variance is determined by genetic variants 4 , while the remainder of the variation is explained by factors such as nutrition, physical exercise, and others 2 . In the case of physical exercise, recommendations for improvement in bone health in childhood and adolescence are based on exercises that generate mechanical overload on the bone and are carried out at moderate/vigorous intensity 5 .Accordingly, different sports include these characteristics, such as basketball. Basketball is a collective dynamic sports activity, which includes significant mechanical impact on bones (running, jumping, quick changes of direction, etc.) and is performed predominantly at moderate and vigorous intensity (intermittent feature) 6 . Moreover, although widely practiced throughout the world, there is a shortage of scientific studies identifying the possible beneficial impact on bone growth and development in children and adolescents. The majority of these studies focus on international populations and sports such as soccer, tennis, swimming, and gymnastics 7-10 and therefore very little is known about the adaptations that occur in the skeletons of young people exposed to basketball practice.In this sense, the objective of this study was to analyze the impact of basketball practice on bone mineral density (BMD) in male adolescents. AbstractIntroduction: In recent decades, the prevalence of osteoporosis has significantly increased, impacting in a significant manner on health care costs worldwide.

“…For instance, Ferry et al 10 found that 12 months of soccer practice enhanced bone mass and geometry, even in post-pubertal adolescents, while this effect was not observed in swimmers. Therefore, the improvement in bone mass through sports participation seems also to be observed in later adolescence when most other maturational events have been completed.…”

“…7 Several sports cause high training load during practice and thus act positively on bone accrual during growth, such as soccer, tennis and rugby. [8][9][10][11] However, the effects on bone mineral variables caused by sports participation performed in hypogravity during adolescence still remain unclear, 10,12 mainly because previous studies failed to control for the burden of important potential confounders in early life, such as training load and biological maturation. 12 In terms of bone mass gain, the pubertal period is responsible for significant accrual of bone mass in both boys and girls.…”

CONTEXT AND OBJECTIVE: Peak height velocity (PHV) is an important maturational event during adolescence that affects skeleton size. The objective here was to compare bone variables in adolescents who practiced different types of sports, and to identify whether differences in bone variables attributed to sports practice were dependent on somatic maturation status. DESIGN AND SETTING: Cross-sectional study, São Paulo State University (UNESP). METHODS:The study was composed of 93 adolescents (12 to 16.5 years old), divided into three groups: no-sport group (n = 42), soccer/basketball group (n = 26) and swimming group (n = 25). Bone mineral density and content were measured using dual-energy x-ray absorptiometry and somatic maturation was estimated through using peak height velocity. Data on training load were provided by the coaches. RESULTS: Adolescents whose PHV occurred at an older age presented higher bone mineral density in their upper limbs (P = 0.018). After adjustments for confounders, such as somatic maturation, the swimmers presented lower values for bone mineral density in their lower limbs, spine and whole body. Only the bone mineral density in the upper limbs was similar between the groups. There was a negative relationship between whole-body bone mineral content and the weekly training hours (β: -1563.967; 95% confidence interval, CI: -2916.484 to -211.450). CONCLUSION: The differences in bone variables attributed to sport practice occurred independently of maturation, while high training load in situations of hypogravity seemed to be related to lower bone mass in swimmers.RESUMO CONTEXTO E OBJETIVO: O pico de velocidade de crescimento (PVC) constitui importante evento maturacional durante a adolescência, afetando o tamanho do esqueleto. O objetivo do estudo foi comparar variáveis ósseas em adolescentes praticantes de diferentes modalidades esportivas, bem como identificar se diferenças nas variáveis ósseas atribuídas à prática esportiva são dependentes do estado da maturação somática. DESENHO E LOCAL: Estudo transversal, Universidade Estadual Paulista (UNESP).MÉTODOS: O estudo foi constituído por 93 adolescentes (12 a 16,5 anos), divididos em três grupos: grupo sem envolvimento esportivo (n = 42), futebol/basquete (n = 26) e natação (n = 25). A densidade e conteúdo mineral ósseo foram mensurados utilizando absortiometria de raio-x de dupla energia e a maturação somática foi estimada através do uso do PVC. Informações sobre volume de treinamento foram fornecidas pelos treinadores. RESULTADOS: Adolescentes com idade tardia no PVC apresentaram maiores valores de densidade mineral óssea em membros superiores (P = 0,018). Após ajustes por variáveis de confusão, como a maturação somática, os nadadores apresentaram menores valores de densidade mineral óssea em membros inferiores, coluna e corpo inteiro. Apenas a densidade mineral óssea de membros superiores foi similar entre os grupos. Existiu relação negativa entre conteúdo mineral ósseo de corpo inteiro e tempo de treino semanal (β: -1563.967; 95%...
