background: the aim of this study was to assess the predictive capacity of body composition estimated by bioelectrical impedance analysis (bia) to identify abnormal blood pressure in physical education and sport teaching students in the city of ankara. methods: data for this cross-sectional study were obtained in the city of ankara in 2014. a total of 133 students aged 20-35 yr participated in ...
relative importance of lean and fat mass on bone mineral density in iranian children and adolescents
conclusions these findings suggest that lean mass was the most important predictor of bmd in both genders. physical activity appears to positively impact on lean mass and needs to be considered in physical education and health-enhancing programs in iranian school children. background body weight is made up of lean and fat mass and both are involved in growth and development. impression of these...
forty growing ram lambs (lori-bakhtiari breed) averaging 28 kg (±1.5) were allocated in this study to evaluate the optimal dietary energy density in a lamb fattening enterprise in iran. the feed intake (fi), body weight (bw), gain to feed ratio (g:f) and carcass characteristics were studied. four treatments differed in metabolizable energy content (me) as follow; 2, 2.3, 2.6 and 2.9 mcal/kg for...
background: the aim was to investigate the relationships among lean mass (lm), fat mass (fm), and bone mineral density (bmd) in women stratified by body mass index (bmi) (bmi – normal-weight, overweight, obese) and to determine threshold at which body fat assumes negative relationship with bmd. methods: this was a cross-sectional study in 471 healthy caucasian women, aged 18-67 years. bmd, lm, ...
background: women engaged with polycystic ovarian syndrome (pcos), as the commonest endocrine disorder, are known to have a specific type of adiposity. birth weight is among different contributors reported to be responsible for this diversity. objective: we aimed to compare the relation between birth weight and body fat mass (bfm)/ body lean mass (blm) in pcos and their age and body mass index ...
BACKGROUND Weight loss may contribute to the loss of lean mass with age. OBJECTIVE The objective was to evaluate the relation between weight loss or weight gain and changes in lean mass and fat mass in older adults. DESIGN We observed changes in weight and body composition during a 4-y period in 2163 men (47%) and women (53%) aged 70-79 y in the Health, Aging and Body Composition Study coho...
Exclusion of the head from total-body dual-energy X-ray absorptiometry (DXA) scans is recommended when measuring pediatric bone mass (1,2).We write to suggest that a similar approach, that is, total body less head (TBLH) measurement, should be considered when measuring total-body lean mass in adults. DXA-measured total-body lean mass is often used as a surrogate for muscle mass in athletic perf...
The obesity phenotype associated with asthma is not known. Our objective was to define the relative contribution of various distributions of fat and lean mass to asthma prevalence. Data were obtained from 2,525 participants (including 1,422 females) who underwent dual-energy X-ray absorptiometry (DEXA) at the year 20 examination in the Coronary Artery Risk Development in Young Adults (CARDIA) c...

BACKGROUND Age-related sarcopenia may cause physical dysfunction. We investigated the involvement of sarcopenia in dropped head syndrome (DHS). METHODS Our study subjects were ten elderly women with idiopathic DHS (mean age 75.1 years, range 55-89). Twenty age- and sex-matched volunteers (mean age 73.0, range 58-83) served as controls. We used a bioelectrical impedance analyzer (BIA) to analy...
