“…These results agree with studies of racquet sport athletes that controlled for genetic, hormonal, and nutritional variability while assessing the unilateral effects of physical activity. 43,44 Larger muscle and bone size were observed at both forearm 45 and humerus 43 in these athletes. However, the difference in variance between forearm and upper-arm bones was not explicitly explained by a difference in forearm 45 and upper-arm muscle.…”

Purpose: To investigate the predictive ability of muscle cross-sectional area (MCSA) and body mass on bone mineral content, compressive bone strength index (BSI c ), and the polar stress-strain index (SSI p ) of the forearms and lower legs of middle-aged adults. Methods: A total of 53 healthy adults (37 male, 16 female; mean age 50.4; SD 2.1 y) were scanned with peripheral quantitative computed tomography (pQCT) to measure radius and tibia total and cortical bone mineral content, BSI c , SSI p , and forearm and lower-leg MCSA (BSI c : 4% distal; SSI p and MCSA at 65% and 66% radius and tibia shaft sites, respectively). Multiple regression models adjusted for sex and height were used to assess the relative variance in radius or tibia bone outcomes predicted by body mass and/or forearm or lower-leg MCSA. Results: Forearm MCSA independently predicted total bone-mineral content, BSI c , and SSI p in radius (r partial ¼ 0.59, 0.56, 0.42). Body mass was a negative predictor of radius BSI c (r partial ¼ À0.32) and did not predict other radius outcomes when both body mass and MCSA were forced in the models. In the lower leg shaft, MCSA, and body mass predicted bone content and strength similarly when independently added to the models with sex and height. Conclusions: Forearm MCSA was a dominant predictor of radius bone content and estimated strength. In the tibia, both body mass and lower-leg MCSA contributed to predicting bone content and estimated strength.Key Words: body weight; bone and bones; tomography scanners, X-ray computed; radius; muscle, skeletal; tibia.

“…Participation in asymmetric sport disciplines is connected with asymmetric changes in soft tissues (Ducher et al, 2005;Haapasalo et al, 1998). As was noticed, soft tissues indicate greater lateral differences than skeletal measurements (Van Dusen, 1939;Chhibber & Singh, 1970;Kimura & Asaeda, 1974;).…”

“…Some authors (Maughan et al, 1986) observed greater proportion of muscle and smaller proportion of fat in dominant arm than the opposite limb in tennis players. Numerous studies indicated increased bone density in the dominant limb among tennis players (Ruff et al, 1994;Ducher et al, 2005;Lucki & Nicolay, 2007). Analysis of the bilateral asymmetry among collegiate (19-24 years old) tennis players showed that forearm circumferences of the dominant limb was greater than in the opposite limb (3-10% in female and 2-13% in male tennis players) (Lucki & Nikolay, 2007).…”

“…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%...
