BACKGROUND Endurance athletes have higher high density lipoprotein (HDL) concentrations than sedentary controls. To examine the mechanism for this effect, we compared HDL apoprotein metabolism in 10 endurance athletes aged 34 +/- 6 years (mean +/- SD) and 10 sedentary men aged 36 +/- 8 years. METHODS AND RESULTS Subjects were maintained on controlled diets for 4 weeks, and metabolic studies u...

The objective of this research was to measure the presence of metabolic syndrome risk factors in a sample population in the middle income Caribbean nation of St. Lucia and to identify the demographic and behavioral factors of metabolic syndrome among the study participants. Interviews and anthropometric measures were conducted with 499 St. Lucians of ages 18-99. Descriptive statistics were used...

AIM The aim of this study was to investigate the potential associations of reallocating 30 minutes sedentary time in long bouts (>60 min) to sedentary time in non-bouts, light intensity physical activity (LPA) and moderate- to vigorous physical activity (MVPA) with cardiometabolic risk factors in a population diagnosed with prediabetes or type 2 diabetes. METHODS Participants diagnosed with p...

BACKGROUND Sedentary behavior is related to increased mortality risk. Whether such elevated risk can be offset by enhanced physical activity has not been examined using accelerometry data. MATERIALS AND METHODS We examined the relations of sedentary time and physical activity to mortality from any cause using accelerometry data among 1,677 women and men aged 50 years or older from the Nationa...

background: the balance between production of reactive oxygen species (ros) and antioxidant defense in the body has important health implications. the aim of this study was to investigate the changes in salivary antioxidants: catalase, vitamin c and brain-derived neurotrophic factor (bdnf), in sedentary men at rest and after acute exhaustive exercise.   methods: this randomized controlled clini...

Background. Sedentary behaviour is associated with health risks, independent of physical activity. This study aimed to investigate patterns of sedentary behaviour and physical activity among stroke survivors in rehabilitation hospitals. Methods. Stroke survivors admitted to four Swedish hospital-based rehabilitation units were recruited ≥7 days since stroke onset and their activity was measured...

Purpose: To compare the ability of SenseWear Mini (SWm) and Actigraph GT3X (AG3) accelerometers to differentiate between healthy adults' observed sedentary and light activities in a laboratory setting. Methods: The 22 participants (15 women, 7 men), ages 19 to 72 years, wore SWm and AG3 monitors and performed five sedentary and four light activities for 5 minutes each while observed in a labora...

BACKGROUND Concern over the health risks of sedentary behavior has highlighted the need to examine factors associated with screen-based (television/computer) sedentary behavior. The present study examined the association of screen-based sedentary behavior with body weight and sociodemographic attributes among Japanese adults. METHODS A population-based cross-sectional study enrolled 1034 Japa...

PURPOSE The detrimental effects of sedentary time on health may act by replacing time spent in physical activities. The aim of this study was to examine cross-sectional associations between objectively assessed sedentary and physical activity domains and cardiometabolic risk factors using a novel isotemporal substitution paradigm. METHODS Participants were 445 healthy men and women (mean age,...

BACKGROUND AND OBJECTIVES Prolonged sitting time (ST) has negative consequences on health. Changing this behavior is paramount in overweight/obese individuals because they are more sedentary than those with normal weight. The aim of the study was to establish the pattern of sedentary behavior and its relationship to health, socio-demographics, occupation, and education level in Catalan overweig...
