Assessment of free-living daily physical activity in older claudicants: validation against the doubly labeled water technique.
BACKGROUND The purpose of this study was to compare physical activity assessed by monitoring devices and questionnaires with the criterion method of physical activity using doubly labeled water (DLW) in free-living peripheral arterial occlusive disease (PAOD) patients. METHODS Twenty-two older nonsmoking PAOD patients with intermittent claudication (age = 68.7 +/- 7.3 years, ankle/brachial in...
متن کاملValidation of Web-Based Physical Activity Measurement Systems Using Doubly Labeled Water
BACKGROUND Online or Web-based measurement systems have been proposed as convenient methods for collecting physical activity data. We developed two Web-based physical activity systems-the 24-hour Physical Activity Record Web (24hPAR WEB) and 7 days Recall Web (7daysRecall WEB). OBJECTIVE To examine the validity of two Web-based physical activity measurement systems using the doubly labeled wa...
متن کاملActive-Q: Validation of the Web-Based Physical Activity Questionnaire Using Doubly Labeled Water
BACKGROUND Increased use of the Internet provides new opportunities for collecting data in large studies. The aim of our new Web-based questionnaire, Active-Q, is to assess total physical activity and inactivity in adults. Active-Q assesses habitual activity during the past year via questions in four different domains: (1) daily occupation, (2) transportation to and from daily occupation, (3) l...
متن کاملInfluence of body composition on physical activity validation studies using doubly labeled water.
This study investigated the influence of two approaches (mathematical transformation and statistical procedures), used to account for body composition [body mass or fat-free mass (FFM)], on associations between two measures of physical activity and energy expenditure determined by doubly labeled water (DLW). Complete data for these analyses were available for 136 African American (44.1%) and Hi...
متن کاملThe Short Questionnaire to Assess Health-Enhancing (SQUASH) Physical Activity in Adolescents: A Validation Using Doubly Labeled Water.
BACKGROUND Accurate assessment of physical activity energy expenditure (PAEE) among adolescents is important for surveillance, evaluating interventions, and understanding the relation between energy balance and normal physiological and behavioral growth and development. The purpose of this study was to examine the validity of the Short Questionnaire to Assess Health-Enhancing Physical Activity ...
