Background Regular PA is thought to have positive effects on well-being, which might also be explained by anti-inflammatory processes. Previous research has shown that PA is inversely associated with inflammatory responses to stress but this work has been cross-sectional. Given the pivotal role of stress in promoting inflammation and depression, ...
Background The mechanisms underlying the cardia-protective effects of physical activity in older adults remain poorly understood. We examined the relationship between objectively measured physical activity during free-living and novel cardiac risk markers, including coronary artery calcium (CAC) and pericardial fat (PF). Methods Participants were 446 healthy men and women (mean age=66±6 ...
Introduction It is common for patients with chronic renal failure (CRF) to have frequent complaints of low aerobic capacity, muscle weakness and chronic fatigue. The present body of evidence indicates that patient outcome is compromised if total Kt/V is below 1.7 (Lo, 2003; Yao et al., 2001). An adequacy of weekly peritoneal ...
The aim of die present study was to evaluate different aspects of a device designed to monitor physical activity. Measurements of different axes and placement of the monitor were rested using a treadmill with ranging increments in incline or speed. The monitor was also used to assess the level of ...
We measured physical activity after strenuous exercise in 20 women with chronic fatigue syndrome (CFS), compared to 20 sedentary healthy volunteers who exercised no more than once per week. Activity was measured for 2 weeks using a portable waistworn vertical accelerometer. After the first week of activity monitoring, all participants returned for a ...
We examined the ability of the Computer Science Applications (CSA) accelerometer to predict energy expenditure during treadmill walking and stair stepping in nine children and adolescents with cystic fibrosis (CF) (mean age 12.1 yr, SD + 2.8) and ten healthy controls (mean age 10.8 yr. SD + 2.2). The accelerometer was attached above the hip and ...
The authors examined the validity of the Computer Science and Application (CSA) activity monitor during a bout of rehabilitative exercise among older adults with chronic disease. In order to determine convergent validity, 50 participants were monitored during a 30-min walk in Study 1. In order to assess concurrent validity, 10 volunteers wore both ...
Objective Juvenile primary fibromyalgia syndrome (JPFS) is a chronic pain condition associated with significant impairment in physical functioning, but no studies have used newer technologies such as actigraphy to document objective physical activity levels in JPFS. Methods This is the first study to objectively describe physical activity in JPFS patients ...
Objective To investigate the validity of MTI accelerometer as a physical activity (PA) measurement instrument for children with cerebral palsy (CP). Design Participants were classified within Gross Motor Function Classification System I to III and took part in 2 activity sessions: (1) a structured activity protocol with increasing intensities and (2) a free ...
