Interindividual variability in energy intake and expenditure during a weight loss intervention
Association between Phase Angle and Body Composition of Children and Adolescents Diagnosed with HIV Infection
The aim of the study was to investigate how phase angle (PhA) is associated with subtotal and lumbar spine bone mineral density [BMD], lean soft tissue mass [LSTM], total body fat mass, android and gynoid in children and adolescents with HIV according to sex. A cross-sectional study was conducted in Florianópolis, Brazil, involving 64 children and adolescents vertically transmitted with HIV. Resistance and reactance values were obtained using bio…
Phase Angle Is a Marker of Muscle Quantity and Strength in Overweight/Obese Former Athletes
Our findings indicated that former athletes with higher values of PhA exhibited greater muscle mass and strength, despite sex, age, and body composition, which suggests that this simple raw BI parameter can be utilized as an indicator of muscle quantity and functionality in overweight/obese former athletes
Estimating resting energy expenditure from dual‐energy X‐ray absorptiometry
This 3C model, estimating REE from a multicomponent approach, allows a new application of DXA as tool for understanding intraindividual differences in terms of the mass of metabolically active tissue. Sex and populational differences should be taken in account. Consequently, we present qualified sex-specific DXA models that can be applied in different contexts such as health and sports, besides considering interpersonal differences in terms of en…
The Predictive Role of Raw Bioelectrical Impedance Parameters in Water Compartments and Fluid Distribution Assessed by Dilution Techniques in Athletes
A bstract : The aims of this study were to analyze the usefulness of raw bioelectrical impedance (BI) parameters in assessing water compartments and fluid distribution in athletes. A total of 202 men and 71 female athletes were analyzed. Total body water (TBW) and extracellular water (ECW) were determined by dilution techniques, while intracellular water (ICW) was calculated. Fluid distribution was calculated as the ECW/ICW ratio (E:I). Phase ang…
Phase Angle as a Marker of Muscular Strength in Breast Cancer Survivors
the findings of this study suggest that PhA is a significant predictor of maximal forearm isometric strength and a potential indicator of disease-related functionality in BCS
Physical training over 6 months is associated with improved changes in phase angle, body composition, and blood glucose in healthy young males
Objectives The aim of this study was to evaluate the association between phase angle, body composition, and blood glucose changes in healthy young males after 6 months of physical training. Methods Volunteers, 98 healthy males (18.8 ± 0.5 years), had 6 months of progressive physical training (5 days a week, 90 minutes a day). Resistance, reactance, and phase angle were obtained by bioelectrical impedance analysis, body composition (fat mass, bone…
Classic Bioelectrical Impedance Vector Reference Values for Assessing Body Composition in Male and Female Athletes
Bioimpedance standards are well established for the normal healthy population and in clinical settings, but they are not available for many sports categories. The aim of this study was to develop reference values for male and female athletes using classic bioimpedance vector analysis (BIVA). In this study, 1556 athletes engaged in different sports were evaluated during their off-season period. A tetrapolar bioelectrical impedance analyzer was use…
The Role of Somatic Maturation on Bioimpedance Patterns and Body Composition in Male Elite Youth Soccer Players
The purpose of this study was to examine the influence of chronological age (CA) and somatic maturation on body composition (BC) and bioimpedance parameters in male elite soccer players. BC and bioimpedance variables were measured in a sample of 249 players aged 9-18 years of age and registered in two professional Italian soccer teams. Results from segmental analysis showed transition time points where the influence of CA and somatic maturation o…
Prevalence of physical activity through the practice of sports among adolescents from Portuguese speaking countries
This study evaluated the prevalence of physical activity through the practice of sports in adolescents from schools in two Brazilian cities and a Portuguese school, and its association with independent variables, such as gender and age. A cross-sectional study was conducted of schoolchildren from two cities in Brazil and one in Portugal. The total study sample was 3694 subjects (1622 males and 1872 females). Physical activity levels were assessed…
Are cardiorespiratory fitness and moderate‐to‐vigorous physical activity independently associated to overweight, obesity, and abdominal obesity in elderly
OBJECTIVES: This study aimed to examine the independent association of cardiorespiratory fitness (CRF) and physical activity (PA) with overweight and total and abdominal obesity in an elderly population. METHODS: A total of 112 males and 185 females, 65-103 years, were assessed for PA with accelerometers and results from six-minute walk test were used as a CRF marker. Waist circumference was dichotomized into normal or abdominal obesity and BMI w…
Is bioelectrical impedance spectroscopy accurate in estimating total body water and its compartments in elite athletes
Overall, these findings demonstrate the validity of BIS as a valid tool in the assessment of TBW and its compartments in both male and female athletes
Ethnicity‐related skeletal muscle differences across the lifespan
Despite research and clinical significance, limited information is available on the relations between skeletal muscle (SM) and age in adults, specifically among Hispanics, African Americans (AA), and Asians. The aim was to investigate possible sex and ethnic SM differences in adults over an age range of 60 years. Subjects were 468 male and 1280 female adults (≥18 years). SM was estimated based on DXA‐measured appendicular lean‐soft tissue using a…
