Introduction
There is concern that preschool children are not physically active enough to benefit health, yet few interventions have attempted to increase physical activity (PA) in this population. This study aimed to investigate the effectiveness of a 6-week school based Active Play intervention on children’s moderate-to-vigorous physical activity (MVPA) ...
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 ...
Introduction
Feedback and monitoring physical activity (PA) may have a role decreasing sedentary behavior. The aim of this study was to test the effectiveness of a Polar Activity Computer (FA20, Polar Electro Oy, Kempele, Finland) in increasing PA in daily life over 6 month.
Method
50 volunteer healthy subjects were randomly assigned ...
Introduction
Knowing the degree of physical activity in a population group becomes the first step to address sport promotion policies to encourage a healthy lifestyle that may have impact on better living conditions. Traditionally, we have used questionnaires and log books to ascertain the practice of physical activities and sports. ...
Background
Physical inactivity is a risk factor for obesity, cardiovascular disease, hypertension, and other chronic diseases that are increasingly prevalent in the U.S. and worldwide. Time at work represents a major portion of the day for employed people.
Purpose
To determine how employment status (full-time, part-time, or not employed) ...
Introduction Pattern recognition classification algorithms have successfully identified energy cost and activity type from hip-worn accelerometers (ACC) [1,2]. These algorithms evaluate attributes of the acceleration signal during high frequency sampling. ACC output similarities and differences across activity types are well characterized [3]. An often overlooked area of potential difference lies in movement ...
Introduction
Most accelerometry research is in children and adults. Literature on accelerometry in older adults is limited and many studies rely on validity studies completed on younger adults to determine cutpoints for exercise intensity. The purpose of this study was: to review the literature to identify studies that used ActiGraph ...
Introduction
The interest in physical activity (PA) to prevent pediatric obesity has increased during the past decade. However, to start with obesity preventative efforts, adequate measurements of PA are needed. Although accelerometers have been put forward as an adequate method to assess preschoolers’ PA, survey measures of PA can be ...
Introduction
The most popular accelerometers in physical activity research are the Actigraph uniaxial accelerometer (AGR, Model GT1M, Actigraph, Shalimar, CA) and the RT3 triaxial accelerometer (Stayhealthy Inc, Monrovia, CA). When a large population is evaluated at the same time, the use of several accelerometers is necessary. To be able ...
Introduction
The aims of this study were to assess the quality of data on physical activity obtained by recall from British Pakistani women, and to explore the feasibility of using accelerometer-based physical activity monitors to provide more objective measure of physical activity in this group. Previously only questionnaire data have ...
