BACKGROUND Weight loss may contribute to the loss of lean mass with age. OBJECTIVE The objective was to evaluate the relation between weight loss or weight gain and changes in lean mass and fat mass in older adults. DESIGN We observed changes in weight and body composition during a 4-y period in 2163 men (47%) and women (53%) aged 70-79 y in the Health, Aging and Body Composition Study coho...

Obesity in combination with unhealthy life style may increase the risk of chronic diseases. Objectives: This study aimed to determine the gender difference of body composition and respiratory functions among medical students and its relationship with their life style. This study was performed on 165 male and female students. Body mass index (BMI) and body composition parameters were assessed us...

This review summarizes the association between directly assessed physical activity and adiposity in preschool children (age 1.5-6 years). It includes 17 cross-sectional and longitudinal studies that were published between January 1999 and February 2010. The association between physical activity and obesity seems to depend on the outcome measure of adiposity. In 60% (3/5) of the studies using pe...

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 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...

BACKGROUND Both body fat distribution and adipocyte size are associated with metabolic abnormalities. OBJECTIVE We defined the extent to which subcutaneous adipocyte size is related to regional fat mass and to the sizes of adipocytes in other subcutaneous depots independent of adiposity, age, and sex. DESIGN Data collected from 188 women and 133 men who were 18-50 y old and who had a body m...

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 ...

OBJECTIVES To investigate the validity of an axiom that body mass index (BMI) and percentage body fat (%BF), above an ideal, are health risk factors. METHODS Participants were 2615 volunteers who participated in a health-screening program conducted in college residence halls over a consecutive 8-year period. RESULTS Nearly half of all participants were misclassified when BMI and/or %BF were...

OBJECTIVE To verify the influence of programmed physical activity on body composition among adolescent students during 1 school year. METHODS The sample included 383 students (age range: 10 to 15 years) separated into two groups: 186 cases (96 male and 90 female) and 197 controls (108 male and 89 female). This was an intervention study with pre- and post-test assessments in which intervention...
