Background: Beach handball is a recent team sport characterized by defensive and offensive actions on a sand surface. Scientific evidence has shown that body composition is fundamental in sports performance. The main objective of this study was to know the body composition, anthropometric characteristics, and bone mineral density of elite beach handball players. Furthermore, another purpose was to analyze the differences between categories (junior and senior) and playing position. Methods: A descriptive, cross-sectional study of 36 male players (18 juniors and 18 seniors) of the Spanish National Beach Handball Team was conducted. Full profile anthropometry and calcaneal ultrasound measurements were used. Results: Significant differences between categories (p < 0.05) were found in: height, body mass, arm span, BMI, muscle mass, fat mass, bone mass, skinfolds, and body perimeters. The somatotype changes depending on the playing position. Bone mineral density of the players was adequate. No significant differences were found by playing position. Conclusions: Senior players had a better body composition due to the presence of less fat mass than junior players. This study provides reference values of elite junior and senior beach handball players and by playing positions. This data is useful for the identification of talents and players who should be trained to improve their body composition.

The Relationship

Background:The relationship between lean mass (LM), fat mass (FM) and bone mineral density (BMD) remains controversial. Some population studies have emphasized the positive association between them, while others have found an inverse relationship. RA patients are characterized by a decrease in muscle mass and an increase in fat mass. Such changes in body composition may be associated with low BMD.Objectives:To study the relationship between BMD, LM and FM in postmenopausal women with RA.Methods:68 postmenopausal women with RA (median age 59 [54; 63] years) were included in the study. BMD and body composition were evaluated using two-energy X-ray absorptiometry. Correlation analysis between body composition parameters and BMD was performed with the Spearman method, correlation coefficients R for p<0.05 are presented.Results:The average L1-L4 BMD was 0,92±0,16 g/cm2, total hip BMD - 0,84±0,15 g/cm2 and femoral neck - 0,73±0,13 g/cm2. 33 (48.5%) women had osteopenia, and 17 (25.0%) - osteoporosis (OP). Low appendicular LM was found in 5 (7.4%) and low appendicular muscle index (appendicular LM/height2, AMI) – in 10 (14.7%) patients. Overfat was revealed in 47 (69.1%) women, but only 20 (29.4%) women had BMI corresponding to obesity. The positive correlations between BMD in L1-L4, total hip and femoral neck regions and body weight (R=0.46, R=0.56 and R=0.50, respectively), trunk fat (R=0.4, R=0.51 and R=0.37, respectively), total FM (R=0.27, R=0.43 and R=0.34, respectively), trunk LM (R=0.55, R=0.54 and R=0.51, respectively), total LM (R=0.51, R=0.50 and R=0.52, respectively), appendicular LM (R=0.31, R=0.29 and R=0.37, respectively) and AMI (R=0.26, R=0.33 and R=0.51, respectively) were found out. In the multivariate linear regression analysis total LM was associated with BMD of lumbar spine (β=0.638, p=0.001) and total hip (β=0.473, p=0.008), and AMI - with femoral neck BMD (β=0.360; p=0.014). We found that FM hadn’t a significant effect on BMD in any region.Conclusion:73.5% of patients with RA had a reduced BMD, and 14.7% women – low AMI. LM was positively associated with BMDs in different regions of interest, but FM had no effect on BMD. Further researches are needed to identify associations between body composition, inflammatory activity and bone health in patients with RA.Disclosure of Interests:None declared

ABSTRACT Objective To evaluate bone mineral mass in adolescents with failure to thrive in relation to body composition. Methods A case control study involving 126 adolescents (15 to 19 years), in final puberty maturation being 76 eutrophic and 50 with failure to thrive (genetic or constitutional delay of growth), of matching ages, gender and pubertal maturation. The weight, height and calculated Z score for height/age and body mass index; bone mineral content, bone mineral density and adjusted bone mineral density were established for total body, lower back and femur; total fat-free mass and height-adjusted fat-free mass index, total fat mass and height-adjusted. The statistical analyses were performed using the Student's t-test (weight, height and body composition); Mann-Whitney test (bone mass) and multiple linear regression (bone mass determinants). Results weight, height and height/age Z-score were significantly higher among eutrophic subjects. Both groups did not show statistically significant differences for fat mass, percentage of fat mass, total fat mass height adjusted and fat-free mass index height sadjusted. However, total free fat maass was smaller for the failure to thrive group. Conclusions There was no statistically significant difference for bone mass measurements among adolescents with failure to thrive; however, the factors that determine bone mass formation should be better studied due to the positive correlation with free fat mass detected in these individuals.

ABSTRACT Objective: To evaluate the association between bone mineral density (BMD) and body composition in healthy older adults at different skeletal sites. Methods: We analyzed 87 medical records and BMD along with the body composition of men ranging from 60 to 87 years of age (mean: 68.5, standard deviation: 6.5). Inclusion criteria were normal BMD values (T-score greater than or equal to -1.0) and body mass index within normal or overweight range (18.5 to 29.5 kg/m2). Body composition was evaluated using bone densitometry with dual-energy X-ray absorptiometry (DEXA) in a LUNAR-DPX apparatus. Results: Greater lean mass, fat mass, and soft tissue was associated with better BMD values in older adults, and higher age was associated with poorer BMD. Conclusion: Body composition (lean and fat masses and soft tissue) in older men is positively associated with BMD at all body sites (arms, legs, and trunk).

ObjectiveAdverse body compositional features and low bone mineral density (BMD) are the characteristic of patients with active Cushing's syndrome (CS). The aim of this study was to evaluate body composition and BMD in women with CS in long-term remission and the influence of polymorphisms in genes affecting glucocorticoid (GC) sensitivity on these end-points.Design, patients and methodsThis was a cross-sectional, case–controlled study, including 50 women previously treated for CS and 50 age and gender-matched controls. Median (interquartile range) remission time was 13 (5–19) years. Body composition and BMD were measured with dual-energy X-ray absorptiometry. Five polymorphisms in four genes associated with GC sensitivity were analysed using TaqMan or Sequenom single-nucleotide polymorphism genotyping.ResultsPatients with CS in remission had increased abdominal fat mass (P<0.01), whereas BMD was not significantly different at any site between patients and controls. In patients, the NR3C1 Bcl1 polymorphism was associated with reduced total (P<0.05) and femur neck BMD (P<0.05). The polymorphism rs1045642 in the ABCB1 gene was associated with increased abdominal fat mass (P<0.05) and decreased appendicular skeletal muscle mass (P<0.05). GC replacement was associated with reduced total BMD (P<0.01), BMD at lumbar spine (P<0.05) and increased abdominal fat (P<0.01).ConclusionOngoing GC replacement therapy together with polymorphisms in two genes related with GC sensitivity is associated with abdominal obesity and adverse skeletal health in patients with CS in long-term remission.
