Objective: To determine the extent that physical activity accounts for changes in body composition and body weight over time, independent of dietary intake and other potential confounding factors. Methods and Procedures: A cohort of 256 women ages 35-45 at baseline participated in the study. A prospective design was utilized with baseline and follow up assessments 20-months apart. Primary asses...

The blood lactate level has been used as an indicator of the ability to perform endurance exercise in clinical practice (1). Moreover, during high intensity exercise, lactate production is higher than its removal from the body. Therefore, the lactate threshold (LT) level is an excellent indicator for predicting endurance capacity (1). Individuals with a high LT level have delayed onset of muscl...

BACKGROUND Reduced fetal growth is associated with differences in body composition in adult life that may predispose to cardiovascular disease and diabetes. Most published data are based on simple anthropometric measures, which incompletely describe body composition. OBJECTIVE The objective was to assess body composition and fat distribution by using dual-energy X-ray absorptiometry (DXA). ...

Background : The purpose of this study was to examine the influence of combined training program on C-reactive protein (CRP) serum and interleukin-6 (IL-6) plasma concentrations in sedentary men. Materials and Methods: In this quasi-experimental study, twenty sedentary men (23±2 years) volunteers (with no history of regular exercise program, weight deviation more than 2 kg, special disease and...

  Purpose: Military personnel are expected to maintain the highest possible level of physical   fitness to do their duties. Several factors including body composition and body mass index   affect the level of their physical preparedness. The current study was designed to investigate   the effect of body composition and body mass index in the level of physical preparedness of   Iranian military ...

BACKGROUND Associations between abnormal body fat distribution and clinical variables are poorly understood in pediatric HIV disease. OBJECTIVE Our objective was to compare total body fat and its distribution in perinatally HIV-infected and HIV-exposed but uninfected (HEU) children and to evaluate associations with clinical variables. DESIGN In a cross-sectional analysis, children aged 7-16...

background and objectives: sarcopenia is explained as age-related reduction in muscle mass and performance. some of the most important risk factors for sarcopenia include age, malnutrition, and sedentary life style. the aim of this study was to investigate the association of food intake and physical activity with body composition, muscle strength and muscle function in post-menopausal women. ma...

introduction: inappropriate body composition represents impaired energy and nutrient intake and can be a risk factor for many diseases, especially for cardiovascular disease. different methods have been suggested for the estimation of body fat volume and its distribution. however, they may be either expensive or hazardous for some groups of patients. sonography is a very accessible technique, w...
