BACKGROUND Regular physical activity (PA) confers many positive effects on health and well-being. Sedentary behavior (SB), in turn, is a risk factor for health, regardless of the level of moderate to vigorous PA. The present study describes the levels of objectively measured SB, breaks in SB, standing still and PA among Finnish adults. METHODS This cross-sectional analysis is based on the sub...

Sedentary behavior (SC) in youth has been presented as a predictor of these young people becoming sedentary adults for the rest their lives, potentially leading to onset chronic diseases. SD directly affects motor behavior, thus reducing competence skills related age group between 3 and 18 years old. The objective this study was evaluate influence full-time school environment on gross developme...

OBJECTIVE To investigate the degree to which genetic and environmental influences affect individual differences in sedentary behavior throughout adolescence. DESIGN Cross-sectional twin-family design. SETTING Data on self-reported sedentary behavior from Dutch twins and their nontwin siblings. PARTICIPANTS The total sample consisted of 5074 adolescent twins (aged 13-19 years) and 937 sibl...

The influence of age on reproductive performance of an aphidophagous ladybird beetle, Propylea dissecta was examined using male and female beetles of varying ages (1-30 days) after a single mating stimulus. All the intermediate (10 to 20 days old) and old (30 days old) age females mated with all intermediate and old age males, while only a fraction (0.29%) of younger females, 1 to 5 days old, m...

BACKGROUND Few studies have investigated patterns of physical activity in a multi-ethnic Asian urban population. Even less is known about sedentary behaviors in these populations. The present study examined the prevalence of physical activity, exercise and sedentary behavior. In addition, it investigated socio-demographic correlates and the contribution of different domains towards overall phys...

OBJECTIVES (1) To develop and internally-validate Euclidean Norm Minus One (ENMO) and Mean Amplitude Deviation (MAD) thresholds for separating sedentary behaviours from common light-intensity physical activities using raw acceleration data collected from both hip- and wrist-worn tri-axial accelerometers; and (2) to compare and evaluate the performances between the ENMO and MAD metrics. METHOD...

OBJECTIVES We used linked existing data from the 2006-2008 American Time Use Survey (ATUS), the Current Population Survey (CPS, a federal survey that provides on-going U.S. vital statistics, including employment rates) and self-reported body mass index (BMI) to answer: How does BMI vary across full time occupations dichotomized as sedentary/non-sedentary, accounting for time spent in sleep, oth...

BACKGROUND It remains uncertain whether obesity is an independent risk factor for coronary heart disease in young adults, as well as adults, in Japan. METHODS AND RESULTS In the present study, 1,260 cases of acute myocardial infarction (AMI) and 3,775 community controls were recruited from the AMI-Kyoto Multi-Center Risk Study and Kyoto Citizen's Health and Nutrition Study, respectively. Obes...

We measured leg blood flow (LBF), drew arterial-venous (A-V) blood samples, and calculated muscle O(2) consumption (VO(2)) during incremental cycle ergometry exercise [15, 30, and 99 W and maximal effort (maximal work rate, WR(max))] in nine sedentary young (20 +/- 1 yr) and nine sedentary old (70 +/- 2 yr) males. LBF was preserved in the old subjects at 15 and 30 W. However, at 99 W and at WR(...
