BACKGROUND Sarcopenia is associated with loss of independence and ill-health in the elderly although the causes remain poorly understood. We examined the association between two screen-based leisure time sedentary activities (daily TV viewing time and internet use) and muscle strength. METHODS AND RESULTS We studied 6228 men and women (aged 64.9 ± 9.1 yrs) from wave 4 (2008-09) of the English...

Excessive sedentary behavior is associated with negative health outcomes independent of physical activity. Objective estimates of time spent in sedentary behaviors are lacking among adults from diverse Hispanic/Latino backgrounds. The objective of this study was to describe accelerometer-assessed sedentary time in a large, representative sample of Hispanic/Latino adults living in the United Sta...

BACKGROUND There is rapidly-emerging evidence on the harmful health effects of sedentary behaviors. The aim of this paper was to quantify time in sedentary behaviors and document socio-demographic variations in different life domains among adults. METHODS A population-based survey was carried out in 2012 through face-to-face interviews with Brazilian adults aged 20+ years (N = 2,927). Informa...

BACKGROUND Sedentary behavior is related to obesity, but measures of sedentary behaviors are lacking for adults. The purpose of this study was to examine the reliability and validity of the Sedentary Behavior Questionnaire (SBQ) among overweight adults. METHODS Participants were 49 adults for the 2 week test-retest reliability study (67% female, 53% white, mean age = 20) and 401 overweight wo...

This study compared the body water turnover in endurance athletes and age-matched sedentary men. Eight competitive enduranee athletes (20.8 ± 1.9 yr) and age-matched eight sedentary men (21.6 ± 2.5yr) participated in this study. Total body water and body water turnover were measured using the deuterium (D20) dilution technique. Urine samples were obtained every day for 1Odays after oral adminis...

This study examined: (a) differences in lung function between current and non current smokers who had sedentary lifestyles and non sedentary lifestyles and (b) the mediating effect of sedentary lifestyle on the association between smoking and lung function in African Americans. Sedentary lifestyle was defined as the lowest quartile of the total physical activity score. The results of linear and...

Background- Cardiovagal baroreflex sensitivity (BRS) declines with age but is favorably modulated by habitual aerobic exercise. We tested the hypothesis that compliance (transducing capacity) of an elastic artery in which baroreceptors are located is associated with these age-exercise interactions. Methods and Results- Nine young (28+/-1 years old) and 9 older (65+/-1) sedentary and 10 young (2...

OBJECTIVES Left ventricular diastolic dysfunction with preserved systolic function (DD-PSF) is associated with an increased risk of morbidity and mortality. Population-based surveys studying the associations between DD-PSF and lifestyle-associated risk factors, such as leisure time physical activity (LTPA) and smoking, are scarce. Thus, the aims were to explore the associations between DD-PSF a...

cognitive performance such as prediction and reaction time changes along with aging. it seems that regular lifetime physical activity depends on the delay of these factors. this study aimed at investigating the effect of pilates training on the improvement of motor performance of sedentary elderly men in kermanshah city. 40 sedentary elderly men (mean age 72.15 ± 6.54 years) were selected from ...
