Results: Twenty minutes after eating (3847±900 kJ), body mass (LBIA= 0.8 kg, SBIA= 0.8 kg, MFBIA= 0.7 kg, P< 0.05), impedance (LBIA= 6.0 Ω, SBIA= 17.9 Ω, MFBIA= 27.1 Ω, P< 0.05) and% BF (LBIA= 0.9%, SBIA= 1.7%, MFBIA= 0.8%, P< 0.05) increased significantly and remained elevated at 60 min POST. During the CON trial, a consistent body mass reduction (60–80 g) and impedance increase (4–9 Ω) was observed over time resulting in a small increase in% BF (0.3–0.7%) 60 min POST (P< 0.05). Conclusions: Twenty minutes after …

Background/Objectives:(1) To cross-validate tetra-(4-BIA) and octopolar (8-BIA) bioelectrical impedance analysis vs dual-energy X-ray absorptiometry (DXA) for the assessment of total and appendicular body composition and (2) to evaluate the accuracy of external 4-BIA algorithms for the prediction of total body composition, in a representative sample of Swiss children. Subjects/Methods: A representative sample of 333 Swiss children aged 6–13 years from the Kinder-Sportstudie (KISS)(ISRCTN15360785). Whole-body fat-free mass (FFM) and …

RESULTS: High coefficients of determination (R 2) for whole-body FM (R 2= 0.94, se of estimate (SEE)= 1.2 kg), whole-body LM (R 2= 0.85, SEE= 1.4 kg), and appendicular FM (R 2= 0.82, SEE= 1.1 kg) were observed between SMF-BIA and DXA. The R 2 coefficient for appendicular LM was moderate (R 2= 0.76, SEE= 0.8 kg). Bland–Altman plots demonstrated that there was systematic (constant) bias (that is, DXA minus SMF-BIA) with overestimation of whole-body FM (bias=− 1.2 kg, 95% confidence interval (CI)=− 1.5 to− 0.1) and …

Objective We compared body composition estimates using an eight-electrode, segmental, multiple-frequency bioelectrical impedance analysis (segmental MF-BIA) and dual x-ray absorptiometry (DXA) in a group of healthy adults with a range of body mass indexes (BMIs). Methods Percentage of body fat (% BF), fat-free mass, and fat mass assessed by DXA and segmental MF-BIA in 132 healthy adults were classified by normal (N; 18.5–24.9 kg/m 2), overweight (OW; 25–29.9 kg/m 2), and obese (OB; 30–39.9 kg/m 2) BMI. Results Compared …

Ultrasound techniques are emerging as a cost-effective alternative to body composition analysis. However, ultrasound wanding at seven sites used for the Jackson and Pollock has not been investigated in comparison to bio-electrical impedance (BIA) body composition analysis (BCA) techniques. A convenience sample (N= 48; Male n= 19, Female n= 29) volunteered and completed the study. Body fat percentage was assessed using the multi-frequency InBody 520 octopolar BIA (MF-BIA) and the BodyMetrix® BX2000 Ultrasound …

Patients with acute/critical illness are particularly vulnerable to muscle loss and fluid shifts, which adversely impact clinical outcomes. Assessment of these parameters in hospital settings is often subjective and imprecise, which creates discrepancies in identification and difficulty in assessing longitudinal changes. Body composition (BC) technologies provide objective information about muscle and fluid status that can enhance clinical assessment, and BC variables could be biomarkers for prognosis and targets to monitor intervention …

Young soccer players undertake anthropometric measurements for directing the effectiveness of training programs. However, the use of the eight-electrode electrical bioimpedance method is increasingly being used for the body composition evaluation. The purpose of this study was to compare and correlate body composition, using anthropometric predictive equations, with the use of electrical bioimpedance. Thirty Brazilian high-performance men, players of the U-20 category, participated in the study, while their position …

[Purposes] Although it is recommended to develop a habit of physical activities, there is no easy way to measure skeletal muscle mass in preschool children, which cause the difficulty of evaluation. The purpose of this study was to examine the validity of body composition including the skeletal muscle mass assessment using multi-frequency bioelectrical impedance analysis by comparing body fat mass obtained by using multi-frequency bioelectrical impedance analysis method and body mass index formulas.[Subjects and …

Introduction The aim of this study was to determine the effects of bariatric surgery and weight loss on body composition, serum sclerostin and physical performance. Methods Seventy-three consecutive patients (36 non-surgical controls and 37 who underwent bariatric surgery) were evaluated by means of laboratory tests, multifrequency bioelectrical impedance analysis (BIA), total-body dual-energy X-ray absorptiometry (DXA), gait speed and handgrip strength. Results The differences between non-surgical and surgical patients …

The purpose of this investigation was to utilize several different technologies to compare body composition results across two phases of the menstrual cycle, and to investigate whether being on hormonal birth control or not has any effect on results. The secondary purpose was to determine if body satisfaction or perception of fluid retention differed across phases or between groups. A total of 39 females with a mean age of 26±7 yrs were included in the study, 15 were on hormonal birth control (BC) and 24 were not (non-BC). Participants …
