Objective: The present study aims to assess the associations of adductor pollicis muscle thickness (APMT) with age, skin color, sexual maturation, anthropometric indicators and physical activity in Brazilian adolescents. Materials methods: Cross-sectional adolescents aged 14-19 years. Weight, height, body mass index (BMI), arm circumference (AC), APMT, fat, fat-free (FFM), (FFMI), time color we...

BACKGROUND Chronic Obstructive Pulmonary Disease (COPD) has significant systemic effects beyond the lungs amongst which muscle wasting is a prominent contributor to exercise limitation and an independent predictor of morbidity and mortality. The molecular mechanisms leading to skeletal muscle dysfunction/wasting are not fully understood and are likely to be multi-factorial. The need to develop ...

OBJECTIVES To determine age- and sex-specific body composition reference values and investigate age differences in these parameters for community-dwelling older Japanese men and women, using direct segmental multi-frequency bioelectrical impedance analysis. METHODS We conducted a pooled analysis of data collected in four cohort studies between 2008 and 2012: Kusatsu Longitudinal Study, Hatoya...

Nutritional status deteriorates along with progression of emphysema, with the decline of body composition correlating with risk of disease-related events. Lung volume reduction surgery (LVRS), by improving respiratory function and recovering body composition, may influence long-term disease-related morbidity and mortality when compared to respiratory rehabilitation (RR). In this non-randomised ...

Overweight children and childhood obesity are a public health problem in Mexico. Obesity is traditionally assessed using body mass index (BMI), but an excess of adiposity does not necessarily reflect a high BMI. Thus, body composition indexes are a better alternative. Our objective was to generate body composition percentile curves in children from Mexico City. A total of 2026 boys and 1488 gir...

Chronic Obstructive Pulmonary Disease (COPD) is mainly expressed by weight loss with especially fat-free mass (FFM) depletion and a low body weight correlates with increased mortality and a poor prognosis. We investigated whether anthropometric body composition equations could be used for evaluation of the body composition in COPD. Thirty clinically stable patients with COPD and 13 healthy age ...

BACKGROUND In patients with COPD, we investigated the effect of the fat-free mass (FFM) on maximal exercise capacity and the relationship with changes in operational lung volumes during exercise. METHODS In a cross-sectional study 57 patients (16 females; age 65 ± 8 y) were consecutively assessed by resting lung function, symptom-limited cardiopulmonary exercise test, and body composition by ...

Introduction: Increased adiposity leads to impaired physiologic growth hormone secretion and low high body mass index (BMI) values increase health risks. However, BMI only measures results in variations fat-free (FFM), (FFMI), normalized (NFMI), fat (BFM). This study evaluated the insulin-like factor system responses given exercise their interaction with changes BMI, FFM, FFMI, NFFMI healthy ma...
