OBJECTIVE Physical activity is a modifiable risk factor for type 2 diabetes, partly through its action on insulin sensitivity. We report the relation between insulin sensitivity and physical activity measured by accelerometry. RESEARCH DESIGN AND METHODS This is a cross-sectional study of 346 men and 455 women, aged 30-60 years, without cardiovascular disease and not treated by drugs for diab...

Hypertrophy of the left ventricle is a diagnostic dilemma in subjects who engage in regular endurance exercise. We studied prospectively whether endurance training in previously sedentary young and middle-aged men and women can alter left ventricular (LV) characteristics. We recruited 33 healthy young and middle-aged subjects (18 women, 15 men, ages 21 to 59 years) to undergo 12 weeks of home-b...

OBJECTIVE To verify the association among sociodemographic variables, physical activity level and health-related quality of life in adults aged 20 years and over. METHODS Population-based study, with household sample by clusters. The dependent variables were the PCS and MCS scores of the instrument 36-Item Short-Form Health Survey (SF-36), the independent variables were gathered in sociodemog...

BACKGROUND Parenthood has been associated with declines in leisure-time exercise and moderate-to-vigorous physical activity (MVPA), but less is known about its impact on sedentary time and light-intensity activity. Although the health benefits of MVPA are well established, a growing body of research has been showing that even after controlling for MVPA levels, a detrimental dose-response associ...

BACKGROUND Ethiopia is ninth among the world high tuberculosis (TB) burden countries, pastoralists being the most affected population. However, there is no published report whether the behavior related to TB are different between pastoralist and the sedentary communities. Therefore, the main aim of this study is to assess the pastoralist community knowledge, attitude and perceived stigma toward...

BACKGROUND Knowledge of sedentary behaviour associations with health has relied mainly on television-viewing as a proxy and studies with other measures are less common. To clarify whether sedentary behaviour is associated with disease-risk, we examined associations for television-viewing and sitting at work. METHODS Using the 1958 British birth cohort (n = 7660), we analysed cross-sectional a...

OBJECTIVES To quantify and compare fitness levels of middle aged practitioners of soo bahk do (SBD; a Korean martial art similar to karate) with those of sedentary subjects. METHODS Eighteen volunteers, 14 men and four women (aged 40-60 years), participated. Nine sedentary subjects (mean age 46.7 years) and nine SBD practitioners (mean age 46.8 years) were matched for sex and age. All subject...

Objective: Evaluation of the effect of 8 weeks of High-Intensity Interval Training (HIIT) on the serum level of cardiac troponin T (cTnT) in sedentary obese young men. Materials and Methods: Thirty sedentary men were randomly divided into 3 groups: the 30s HIIT training group (n=10), the 60s training group (n=10), and the control group (no exercise) (n=10). Interval training with 90 %VO2peak w...

Background Sedentary behavior is associated with health risks in adults. The potential benefits of reducing sedentary time may be dependent not only on decrease per se, but also on the type of activity it replaces. Few longitudinal studies have investigated the effects on mortality when replacing objectively assessed sedentary time with another physical activity (PA) behavior. Objective To in...

BACKGROUND Because physical activity may affect risk of certain chronic diseases, we wanted to examine the effects of leisure time physical activity on the metabolic profiles. METHODS In a population-based cohort study, 5220 men and 5869 women, aged 20 to 49 years at entry, took part in 2 surveys (1979-1980 and 1986-1987) with repeated assessments of self-reported leisure time activity. Measu...
