PURPOSE The purposes of this study were to examine patterns of objectively measured sedentary behavior in a national cohort of US middle-age and older adults and to determine factors that influence prolonged sedentary behavior. METHODS We studied 8096 participants from the REasons for Geographic and Racial Differences in Stroke (REGARDS) Study, a population-based study of black and white adul...

Sedentary behaviour is associated with deleterious health outcomes, which differ from those that can be attributed to a lack of moderate to vigorous physical activity. This has led to the field of "sedentary physiology", which may be considered as separate and distinct from exercise physiology. This paper gives an overview of this emerging area of research and highlights the ways that it differ...

BACKGROUND Previous questionnaires targeting older adults' sedentary time have underestimated total sedentary time, possibly by not including all relevant specific sedentary behaviors. The current study aimed to investigate the criterion validity and test-retest reliability of a new questionnaire assessing a comprehensive set of sedentary behaviors. Additionally, we examined whether the criteri...

BACKGROUND School physical education (PE) is considered as an effective channel for youth to accumulate moderate-to-vigorous physical activity (MVPA) and reduce sedentary time. The purpose of this study was to determine the contributing role of PE in daily MVPA and sedentary time among youth. METHODS The study recruited 67 sixth grade children (29 boys; Mean age = 11.75) from two suburban sch...

OBJECTIVE The aim of this study is to examine the associations of total sedentary time and patterns of sedentary time with cardiometabolic biomarkers in a large representative sample of Canadian adults. METHODS The study is based on 4935 adults aged 20-79years, from the 2007/09 and 2009/11 Canadian Health Measures Survey. Total sedentary time, patterns of sedentary time (≥20minute prolonged s...

BACKGROUND Scientific evidence from different sources suggests a positive association between sedentary behaviors and the incidence of hypertension. However, no previous prospective study corroborated this potential relationship in an adult population. Our objective was to assess prospectively the association of different sedentary behaviors (interactive and noninteractive sedentary activity, t...

Limited knowledge is available on lifestyle patterns in Spanish adults. We investigated dietary patterns and possible meaningful clustering of physical activity, sedentary behavior, sleep time, and smoking in Spanish adults aged 18-64 years and their association with obesity. Analysis was based on a subsample (n = 1617) of the cross-sectional ANIBES study in Spain. We performed exploratory fact...

The aim of the present study was to evaluate the effect of regular exercise at 2, 4, 6 weeks intervals on spatial learning and memory in Morris water maze and in passive avoidance test in male diabetic rats. For this purpose, male Wistar rats were divided into four groups, two groups of control rats, one sedentary control and one swimming exercise-trained control and two groups of diabetic rats...
