Body composition is a determinant of performance in soccer. To estimate the body fat percentage (%BF), dual energy X-ray absorptiometry (DXA) effective though this method expensive and not readily accessible. This study examines validity widely used field methods based on anthropometric data bioelectrical impedance analysis (BIA). Participants were 21 male Spanish First Division soccer players ...

BACKGROUND Advances in dual-energy X-ray absorptiometry (DXA) software algorithms have improved the accuracy of this method for body-composition measurement. OBJECTIVE Our objective was to compare the utility of DXA, underwater weighing (UWW), and a multicomponent model (MC) for assessing changes in body composition. DESIGN : Previously sedentary women aged 40-66 y were randomly assigned to...

OBJECTIVE To compare two methods of classifying obesity based on body mass index and body fat percentage. METHODS The cross-sectional study was conducted from November 2012 to August 2013 at Jinnah Postgraduate Medical Centre, Karachi. Male and female volunteers between the ages 15-65 years were selected using simple random sampling. They were classified into different groups for body mass in...

OBJECTIVES The objective of this study was to examine if, in the general population, physically active adults have less body fat after taking body mass index (BMI) into account. DESIGN A cross-sectional analysis of participants recruited into UK Biobank in 2006-2010. SETTING UK Biobank assessment centres throughout the UK. PARTICIPANTS 119 230 men and 140 578 women aged 40-69 years, with ...

BACKGROUND Elevated body mass index (BMI), higher waist-to-hip ratio, and body dissatisfaction have been investigated as risk factors for the development of bulimic symptoms. Central fat deposition may be particularly relevant to eating disorders. To our knowledge, the longitudinal relations between fat distribution, body dissatisfaction, and loss-of-control (LOC) eating development and mainten...

The objective of the study was to develop prediction equations for fat-mass percentage in infants in India based on skinfold thickness, mid-arm circumference, and age. Skinfold thicknesses and mid-arm circumference of 46 apparently-healthy infants (27 girls and 19 boys), aged 6-24 months, from among the urban poor attending a well baby clinic of a hospital in Kolkata were measured. Their body-f...

BACKGROUND In studies of adult humans and in animal models, dietary intakes of the macronutrients, particularly fat, are related to body composition; however, data on children are more scarce. OBJECTIVE We sought to determine whether diet composition is related to percentage body fat in children aged 1.5-4.5 y. DESIGN In 77 preschool children, a 4-d weighed-food record was used to determine...
