BACKGROUND The objectives of this study were to develop a regression model for predicting fat-free mass (FFM) in a population of healthy Taiwanese individuals using standing foot-to-foot bioelectrical impedance analysis (BIA) and to test the model's performance in predicting FFM with different body fat percentages (BF%). METHODS We used dual-energy X-ray absorptiometry (DXA) to measure the FF...

Massage therapy is commonly non-invasive, non-harmful, economical, pleasant, and greatly appreciated by the recipients. The Bioelectrical Impedance Analysis (BIA) method has been identified as one of fastest, simple, safest non-invasive techniques for measuring body bioimpedance parameters after massage therapy. This study aims to evaluate therapy's effect on subject using method. male were mea...

BACKGROUND & OBJECTIVE Skeletal muscle mass represents about 30-40 per cent of the total body weight, and has important roles in function and metabolism. Although newer methods of measuring muscle mass are accurate and sophisticated, there is a need for methods that can be used in low resource settings. Existing methods of predicting muscle mass are based on mid upper arm circumference (MUAC) m...

BACKGROUND & AIMS No generalizable formulas exist that are derived from bioelectrical impedance analysis (BIA) for predicting appendicular lean mass (ALM) and fat mass (AFM) in sarcopenic older adults. Since precision of regional body composition (BC) data in multicentre trials is essential, this study aimed to: 1) develop and cross-validate soft tissue BIA equations with GE Lunar and Hologic D...

Tracking changes in body composition may provide key information about the effectiveness of training programs for athletes. This study reports on agreement between bioelectrical impedance analysis (BIA) and dual-energy X-ray absorptiometry (DXA) tracking during a seven-week offseason program 29 NCAA collegiate American football players. Body subjects (mean ± SD; age: 19.7 1.5 y; height: 179.8 6...

objective(s)bioelectrical impedance is the measure of impedance of the body. impedance consists of electric resistance and reactance. phase angle (pa) is the tan value of the ratio of reactance versus electric resistance. pa depends on cell membrane integrity and on body cell mass. there exists a correlation between pa values and body cell mass.the objective of this study was to compare the pa ...

OBJECTIVES Management of hyponatraemia depends crucially on accurate determination of volaemic (hydration) status but this is notoriously challenging to measure in older people. Bioelectrical impedance analysis (BIA) provides a validated means of determining total body water (TBW), but its clinical utility in determining volaemic status in hyponatraemia has never been tested. This study assesse...

The research goal was to estimate physical development of schoolchildren as per data bioelectrical impedance analysis (BIA) body composition depending on their sex and age. Physical activity (PA) is an important factor in providing welfare this makes the present relevant today. We examined 604 schoolchildren. At a share who have with its duration corresponding WHO recommendations doesn’t exceed...

OBJECTIVE To investigate whether perioperative changes in bioelectrical impedance reflect the severity of illness in pediatric patients after heart surgery. DESIGN Prospective, controlled study. SETTING University-affiliated children's hospital. PATIENTS A total of 107 patients admitted to a pediatric intensive care unit after congenital heart surgery. INTERVENTIONS None. MEASUREMENTS...

BACKGROUND Methods used to estimate percent body fat can be classified as a laboratory or field technique. However, the validity of these methods compared to multiple-compartment models has not been fully established. The purpose of this study was to determine the validity of field and laboratory methods for estimating percent fat (%fat) in healthy college-age men compared to the Siri three-com...
