Purpose The primary aim of this study was to test the validity of two accelerometers, CSA/MTI WAM-7164 and Actiwatch, against direct observation of physical activity using the Children’s Physical Activity Form (CPAF). Methods CSA/MTI WAM-7164 and Actiwatch accelerometers simultaneously measured activity during structured-play classes in 3- to 4...
Introduction Exact evaluation of the quantity and intensity of physical activity in daily life is considered very important due to the close relationship between physical activity level, functional decline and sedentary habits. Even moderate-to-vigorous intense physical activity (PA) is beneficial when done regularly for a total of 30 minutes or longer ...
Background The journey to school is an opportunity for increasing children’s daily physical activity. However, the contribution that active commuting to school makes to overall physical activity is unknown. This study used objective measurement to investigate the physical activity patterns of children by mode of travel To school. Methods ...
Background and Objectives To review the clinimetric quality of motion sensors used to assess physical activity in healthy children and adolescents (2-18 years). Methods A systematic literature search was performed in PubMed, Embase, and SpycINFO. The clinimetric quality of two pedometers (Digi-Walker3 Pedoboy), four one-dimensional accelerometers (LSI, Caltrac, Actiwatch, CSA/...
PURPOSE To describe physical activity levels of children (6-11 yr), adolescents (12-19 yr), and adults (20+ yr), using objective data obtained with accelerometers from a representative sample of the U.S. population. METHODS These results were obtained from the 2003-2004 National Health and Nutritional Examination Survey (NHANES), a cross-sectional study of ...
Understanding the determinants of physical activity behavior in children and youths is essential to the design and implementation of intervention studies to increase physical activity. Objective methods to assess physical activity behavior using various types of motion detectors have been recommended as an alternative to self-report for this population because ...
