As the impact of high-intensity interval training (HIIT) on systemic hormones in aging men is unstudied to date, we investigated whether total testosterone (TT), sex hormone-binding globulin (SHBG), free testosterone (free-T) and cortisol (all in serum) were altered following HIIT in a cohort of 22 lifelong sedentary (62 ± 2 years) older men. As HIIT requires preconditioning exercise in sedenta...

Background: Adults with mental retardation (MR) have been identified as being more sedentary than those without disabilities based on (a) proxy reports of physical activity (PA) and (b) physiological measures such as body composition or cardiovascular fitness. However, there exist no objective, direct comparisons of PA levels between adults with and without MR. The purpose of this study was to ...

OBJECTIVE To quantify longitudinal changes in sedentary behavior (ie, nonexercise seated or lying behavior) after stroke to ascertain whether reducing sedentary behavior might be a new therapeutic target. DESIGN Longitudinal cohort study of patients with acute stroke who were followed over 1 year. SETTING Acute teaching hospital or outpatient clinic, and the community after discharge. PAR...

North Americans spend half their waking hours engaging in sedentary behaviour. Although several recent interventions suggest that short bouts of uninterrupted sedentary behaviour may result in acute increases in cardiometabolic risk, this literature has not been reviewed systematically. This study performed a systematic review of the impact of uninterrupted sedentary behaviour lasting ≤7 days o...

OBJECTIVE The purpose of this study was to assess the effectiveness of a 4-week intervention in which an online personal activity monitor (Gruve-Technologies™) was used to reduce sedentary behavior among sedentary adults. METHOD Eighteen, sedentary adult volunteers (12 men, six women, mean age 29 ± 4.0 years) were recruited to participate in the study. Time spent in sedentary activities and l...

BACKGROUND Sex, age, body mass index (BMI), perceived health and health behavior are correlates known to affect physical activity and sedentary time. However, studies have often been cross-sectional, and less is known about long-term correlates. Thus, the aims were to investigate 1) the associations between a set of characteristics (demographic, biological, psychological, and behavioral) and ob...

Evidence of associations between neighbourhood built characteristics and sedentary behaviours is mixed. The study aim was to investigate the objectively-derived self-reported among Canadian men women. This sourced survey data from Alberta's Tomorrow Project (2008; n = 14,785), in which sitting motor vehicle travel times during last 7 days measured. Geographic Information System used calculate w...
