Longitudinal changes in adult fat-free mass: influence of body weight
Aging, body composition fat-free mass body fat
2016/6/2
Almost all of the data on changes in body composition
during aging are cross-sectional in nature. These show that
fat-free mass (FFM) declines with age.
Determination of skeletal muscle and fat-free mass by nuclear and dual-energy X-ray absorptiometry methods in men and women aged 51–84 y
bioimpedance analysis aging anthropometry
2016/6/1
Skeletal muscle mass (SMM) and fat-free mass
(FFM) are important variables in nutritional studies. Accurate
techniques for measuring these variables have not been thoroughly
validated in elderly su...
Four-component model of body composition in children: density and hydration of fat-free mass and comparison with simpler models
Body fat dual-energy X-ray absorptiometry total body water
2016/5/31
Body composition in children is generally measured
by 2-component (2C) models, which are subject to error
arising from variation in fat-free mass (FFM) composition. The
4-component (4C) model, whic...
Bioelectrical impedance analysis models for prediction of total body water and fat-free mass in healthy and HIV-infected children and adolescents
Bioelectrical impedance analysis pediatrics ethnicity puberty HIV infection
2016/12/19
Background: Bioelectrical impedance analysis (BIA) is an attractive method of measuring pediatric body composition in the field, but the applicability of existing equations to diverse populations...
Anthropometric assessment of muscularity during growth: estimating fat-free mass with 2 skinfold-thickness measurements is superior to measuring midupper arm muscle area in healthy prepubertal children
Anthropometry arm muscle area fat-free mass creatinine grip force peripheral quantitative computer tomography nutritional status muscularity children
2016/12/19
Background: Anthropometric measurements are widely used to determine body composition, especially in children.Objective: Our aim was to compare 2 of the simplest anthropometry-based equation...
Muscle fiber type IIX atrophy is involved in the loss of fat-free mass in chronic obstructive pulmonary disease
Skeletal muscle mass fiber atrophy chronic obstructive pulmonary disease fiber types energy metabolism cross-sectional area
2016/12/19
Background: Although the loss of peripheral muscle mass has been shown convincingly in chronic obstructive pulmonary disease (COPD), the underlying pathogenesis remains unclear.Objective: Th...
Habitual physical activity,anabolic hormones,and potassium content of fat-free mass in postmenopausal women
Total body potassium fat-free mass physical activity aging postmenopausal women estradiol insulin-like growth factor I sarcopenia
2016/12/17
Background: Total body potassium (TBK) is known to decline throughout adulthood. The relations between physical activity, age, anabolic hormones, and TBK have rarely been considered.Objective:...
Skeletal muscle weakness is associated with wasting of extremity fat-free mass but not with airflow obstruction in patients with chronic obstructive pulmonary disease
Skeletal muscle weakness extremity fat-free mass chronic bronchitis emphysema
2016/6/3
Background: Skeletal muscle weakness is a prominent problem in
many patients with chronic obstructive pulmonary disease (COPD).
Objective: The aim of the study was to determine the relation
between...
