The validity of ten popular anthropometric percent fat prediction equations for estimating changes in percentage of body fat for obese females was studied. Thirty-one obese females (mean ± SEM, %fat = 36.7 ± 1.1%, body mass = 75.6 ± 1.7 kg, age = 32.8 ± 1.1 years) participated in a diet-only, diet-plus-exercise, or exercise-only program. Subjects lost 2.7 ± 0.3 fat percentage points and 3.0 ± 0...

purpose weight loss in wrestling has been found to be an interesting issue for researchers. in this regard, complications of weight loss in wrestlers before the competitions and their weight gain in course of competitions have been debated in previous studies. the objective of this study was to investigate the extent of weight gain and to estimate the percentage of body fat in participants in t...

the aim of this study was to estimate body fat percentage through circumference of different parts of body by hydrodensitometry (hydrostatic underwater weighing) as the criterion method and to develop related equations. 158 male students of isfahan university (mean age: 21.6 yrs, height: 174 cm, weight: 69.04 kg, body fat percentage: 15.61 kg, bmi: 22.59) were randomly selected. these subjects ...

Body composition assessment is an important factor in weight management, exercise science and clinical health care. Bioelectrical impedance analysis (BIA) is widely used method for estimating body composition. The purpose of this study was to evaluate segmental multi-frequency bioimpedance method (SMFBIA) in body composition assessment with underwater weighing (UWW) and whole body dual energy x...

the purpose of the present study was to compare some biochemical markers of cancer diseases risk between two groups of active and inactive postmenopausal women. for this purpose, 74 postmenopausal women were required to complete baecke questionnaire. they were divided into two groups: active (age: 55.89±4.38 years, height: 156.93±0.05 cm, weight: 63.18±6.50 kg, body fat percentage: 26.25±6.29, ...

BACKGROUND The nature of body-composition changes in HIV-associated weight loss is unclear. OBJECTIVE We examined the relation between the initial percentage of body fat and the composition of weight loss in men and women with HIV infection. DESIGN HIV-positive adults were seen at semiannual clinic visits, at which time weight, fat, and fat-free mass were determined. The unit of analysis wa...

I . The use of deuterium oxide dilution to obtain an indirect estimate of body water in pregnant ewes was examined and the value of such an estimate in predicting body fat was investigated. 2. Deuterium oxide was infused intravenously into fourteen twin-bearing Blackface ewes and blood samples were taken 6-7 h later. The animals were subsequently slaughtered. 3. Deuterium oxide concentration wa...

BACKGROUND American women aged 25-44 y gain 0.5-1 kg yearly, most of which is fat. Because few midlife women participate in strength training, this mode of activity may be a novel intervention for preventing age-associated fat increases in this population. OBJECTIVES The primary aim was to assess the efficacy of twice-weekly strength training to avoid increases in percentage body fat and intr...

to explore the abnormalities in iranian athletes' electrocardiogram and find any relation with body fat. 239 international athletes were involved in this cross sectional study. body-fat percentage and resting 12-lead ecgs were recorded from all participants. of 239 participant athletes, 212 were male and 27 female. 60% of participants had sinus bradycardia. a total of 84% of the athletes demons...

BACKGROUND To date, there is no consensus regarding adult cutoffs of percentage of body fat or estimated cutoffs on the basis of nationally representative samples with rigorous body-composition measurements. OBJECTIVE We developed cutoffs of percentage of body fat on the basis of the relation between dual-energy x-ray absorptiometry-measured fat mass and BMI (in kg/m(2)) stratified by sex, ag...
