Purpose: Physical inactivity is deleterious to health, but it has been difficult to determine the extent to which these effects are attributable to abnormal body composition or to factors related to physical activity alone. To begin to gauge independent effects of physical activity on health risk, we matched by BMI two groups of normal-weight adolescent females, one physically active (all participants in high school sports), and one sedentary. Methods: Thirty-seven sedentary and 37 physically active adolescent females (mean 15.5 yr) were matched for age and BMI percentile (mean = 58.8). Comparisons included fitness, body composition and bone mineralization (by DEXA), circulating inflammatory cytokines, growth factors, bone-turnover markers, leptin, and adiponectin. Results: Compared with the normal-weight sedentary girls, active girls had significantly (P < 0.05) higher fitness level (peak V?O2 35.5 ± 5.2 vs 24.4 ± 4.1 mL·kg-1·min-1), lean body mass (43.2 ± 4.4 vs 38.7 ± 3.6 kg), bone mineralization (spinal BMD z-scores 0.04 ± 0.88 vs -0.41 ± 0.85), and lower percent body fat (25.4 ± 04.6 vs 29.7 ± 03.7%). Additionally, active girls had lower inflammatory cytokines levels (e.g., TNF-a 1.7 ± 1.3 vs 2.6 ± 2.2 pg·mL-1), and leptin (17.4 ± 11.2 vs 24.7 ± 14.7 ng·mL-1), and higher bone-turnover markers (e.g. osteocalcin 12.6 ± 7.6 vs 7.8 ± 3.0 U·L-1), IGFBP-3 (6416 ± 21280 vs 4247 ± 1082 ng·mL-1), and adiponectin levels (11919 ± 3935 vs 9305 ± 2843 ng·mL-1). Conclusion: The normal-weight, physically active group was fitter and had greater lean body mass, stronger bones, and lower levels of inflammatory markers than did the normal-weight, sedentary group. In adolescent girls, the choice of a lifestyle involving high school sports is characterized by a circulating mediator and body composition pattern that, if sustained, is associated with generally lower long-term risk of cardiovascular disease and osteoporosis

Abstract Objective The presence of metabolic syndrome is associated with a higher degree of inflammation. We sought to assess whether the higher levels of cardiorespiratory fitness attenuate the levels of inflammation in people with metabolic syndrome. Research design and methods We studied 449 consecutive asymptomatic men (47±7 years) who underwent a maximal treadmill exercise test according to the Bruce protocol. Cardiorespiratory fitness was divided into tertiles based on metabolic equivalent...

Cross-sectional research examined whether physical activity or physical fitness was more closely linked to physical self-concept in adolescent females ages 14 to 17 (N = 103, 63% Caucasian). Moderate physical activity and vigorous physical activity were measured through a 3-day physical activity recall. Physical fitness was assessed using highly accurate measures of peak oxygen consumption (via cycle ergometer) and percent body fat (via dual X-ray absorptiometer). The Physical Self-Description Q...

Osteoporosis is a major cause of morbidity and mortality through its association with age-related fractures. Although most effort in fracture prevention has been directed at retarding the rate of age-related bone loss and reducing the frequency and severity of trauma among elderly people, evidence is growing that peak bone mass is an important contributor to bone strength during later life. The normal patterns of skeletal growth have been well characterised in cross-sectional and longitudinal st...

ContextPopulation surveys indicate that physical activity levels are low in the United States. One consequence of inactivity, low cardiorespiratory fitness, is an established risk factor for cardiovascular disease (CVD) morbidity and mortality, but the prevalence of cardiorespiratory fitness has not been quantified in representative US population samples.ObjectivesTo describe the prevalence of low fitness in the US population aged 12 through 49 years and to relate low fitness to CVD risk factors...

Obesity and the metabolic syndrome have both reached pandemic proportions. Together they have the potential to impact on the incidence and severity of cardiovascular pathologies, with grave implications for worldwide health care systems. The metabolic syndrome is characterized by visceral obesity, insulin resistance, hypertension, chronic inflammation, and thrombotic disorders contributing to endothelial dysfunction and, subsequently, to accelerated atherosclerosis. Obesity is a key component in...

There is a wide interindividual variation in peripheral insulin sensitivity at any given body mass index or percent body fat among obese adolescents with normal glucose tolerance. The goals of this study were to determine whether variability in insulin sensitivity is associated with differences in patterns of lipid partitioning or substrate use under fasting and hyperinsulinemic conditions. We compared 14 obese insulin-resistant adolescents with 14 obese insulin-sensitive controls, pair matched ...

Physical activity is associated with a reduced incidence of coronary disease, but the mechanisms mediating this effect are not defined. There has been considerable recent interest in inflammation in the pathogenesis of cardiovascular disease. Some of the beneficial role of physical activity may result from its effects on the inflammatory process. We searched PubMed for articles published between 1975 through May 2004 using the terms exercise, physical activity, or physical fitness combined with ...

Abstract Background: Some markers of chronic inflammation have been recognized as predictors of cardiovascular risk in apparently healthy subjects and in patients with coronary heart disease (CHD). High sensitivity C-reactive protein (CRP) appears to be the most useful marker in clinical settings. Several studies reported associations between inflammatory markers and other cardiovascular risk factors, such as age, obesity, cholesterol levels, the presence of diabetes mellitus, physical activity,...

Bone metabolism fluctuates throughout the reproductive cycle of sows to enable foetal growth and milk production. Although increased bone mineralisation is conceivable in sows during reproduction, a study of mineralisation in function of parity has not been performed. This study evaluated the fluctuations of markers for bone metabolism in primiparous and multiparous sows throughout a reproductive cycle. The experiment included ten multiparous and five primiparous commercial hybrid sows from one ...
