Body fat and lean body mass was assessed in young college students by two different techniques involving NIR method and body circumference measurements. NIR technique significantly over-estimated the body fat as compared to the results obtained by the other method. The difference between the methods was 23-30% high for fat and the variation was 5-9% low for lean body mass for the whole group. R...

METHODS AND RESULTS Seventy Lebanese men (aged 65-84 years) participated in this study. Body weight and height were measured and body mass index (BMI) was calculated. Body composition (lean mass, fat mass and fat mass percentage) was assessed by dual-energy X-ray absorptiometry (DXA). Bone mineral content (BMC) of whole body (WB) and BMD of WB, total hip (TH), femoral neck (FN), ultra distal (U...

This study evaluated the effects of body weight and lean mass abnormalities on health-related quality of life (HRQL) in obstructive airways disease. Body weight, lean mass (using dual-energy X-ray absorptiometry), and HRQL (using the St George's Respiratory Questionnaire (SGRQ)) were measured in 50 patients. Low lean mass was defined as a lean mass index (lean mass/height2) below the fifth perc...

Data are lacking regarding regional morphological changes among women after prolonged physical training. This study employed dual-energy X-ray absorptiometry to assess changes in whole body and regional (i.e., trunk, legs, arms) fat mass, lean mass, and bone mineral content body composition adaptations in 31 healthy women pre-, mid-, and post-6 mo of periodized physical training. These results ...

The purpose was to determine if glutamine supplementation would prevent a loss of lean mass in athletes during a 12-day weight reduction program. It was hypothesized that supplementation would spare lean body mass. Subjects (n=18) exercised and dieted to create a 4186kJ·day(-1) energy deficit and a 8372 kJ·day(-1) energy deficit on days 1-5, days 6-12, respectively. The glutamine (GLN) group (n...

UNLABELLED Metabolic disorders are involved in the pathogenesis of some comorbid conditions such as atherosclerosis and cardiovascular diseases, which frequently occur in COPD patient. These disorders may also associate alterations in body composition. AIM To determine the particularities of body composition, assessing its relationship with respiratory function and clinical status in COPD pat...

OBJECTIVES To investigate the independent contribution of change in sub-total body fat and lean mass to cognitive performance, specifically the executive processes of selective attention and conflict resolution, in community-dwelling older women. METHODS This secondary analysis included 114 women aged 65 to 75 years old. Participants were randomly allocated to once-weekly resistance training,...

BACKGROUND Age-related decreases in lean mass represent a serious health problem. We aimed to analyze the risks of rapid decreases in lean mass by age and sex in relatively young Korean adults during a 4-year follow-up study. METHODS A total of 65,856 non-diabetic participants (59.5% men, mean age 39.1 years) in a health screening program were subjected to bioimpedance body composition analys...
