In spontaneously fasting birds such as penguins, below a body mass threshold corresponding to the phase II-phase III transition, a metabolic and hormonal shift occurs and feeding behaviour is stimulated ('refeeding signal'). The major aim of this study was to determine whether a decrease in non-esterified fatty acid (NEFA) release from adipose tissue could be a component of this signal. Lipolyt...

INTRODUCTION A cross-sectional study was carried out to investigate accelerometer-determined physical activity level of 233 Malay government employees (104 men, 129 women) working in the Federal Government Building Penang, Malaysia. METHODS Body weight, height, waist and hip circumference, body fat percentage and blood pressure were measured for each respondent. All the respondents were asked...

OBJECTIVE To develop an equation for predicting the body density of sumo wrestlers. METHODS The following were measured: subcutaneous fat thickness measured at nine sites using B-mode ultrasound equipment; circumference at seven sites; hand to leg bioelectrical impedance. The subjects consisted of 24 college sumo wrestlers (mean age 19.7 years, mean body weight 111.2 kg) and 24 matched obese ...

The purpose of this study was to examine the effects of a crossfit-based high-intensity power training (HIPT) program on aerobic fitness and body composition. Healthy subjects of both genders (23 men, 20 women) spanning all levels of aerobic fitness and body composition completed 10 weeks of HIPT consisting of lifts such as the squat, deadlift, clean, snatch, and overhead press performed as qui...

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 Numerous data suggest that aerobic-type exercise improves lipoprotein-lipid profiles, cardiorespiratory fitness and body composition in young women. The aim of this study was to evaluate the biological response to high-low impact aerobic fitness among young women. MATERIALS AND METHODS Thirty-four young women aged 22 (19-24) years were divided into three groups: underweight (N=10),...

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...

Objectives: Macrophages are determinant cells for atherosclerotic lesion formation. The objectives of this study were to incorporate macrophage target ligands on the surface of biocompatible and biodegradable epigallocatechin gallate (EGCG)-loaded nanoparticles (Enano), to evaluate their target specificity to macrophages and antiatherogenic effects in vitro and in vivo. Method: The target speci...

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 c...

This study is to analyze the effectiveness of an incentive-based obesity management program (the Midas Project aimed to improve good health habits) at an electronics company in 2005. A total of 95 company participants with a high body mass index (BMI) were recruited for a health promotion program for 3 months that awarded gold medals as an incentive for body fat loss. BMI decreased from 28.8 to...
