Purpose The purpose of this study was to measure and compare physical activity (PA) intensity performed during 10 weeks of U.S. Army Basic Combat Training (BCT) at two training sites (Ft Jackson, SC; Ft Sill, OK). Methods 264 recruits from 11 companies wore an ActiGraph on their waist during waking hours for ...
Background Accelerometers are now the method of choice to objectively assess activity in young children. While numerous cut-points exist for preschoolers, cut points for children aged 1-3 years are limited. Purpose To determine ActiGraph GT1M cut-points for sedentary (SED), light (LPA) and moderate-vigorous physical activity (MVPA) in toddlers. Methods ...
Purpose To examine the test-retest reliability and criterion-related validity of the Yale Physical Activity Survey for Older Adults (YPAS) and Community Health Activities Model Program for Seniors (CHAMPS) survey to assess sedentary behavior (SB) in older adults. Methods Adults aged 65 years and older were recruited to participate in a larger ...
Prior measures of sedentary behavior have not systematically measured sedentary activities in multiple domains and over various routinely performed daily sedentary activities with a user-friendly device. The Sedentary Behavior Record (SBR) was designed to fill the gap in the literature in measuring sedentary behavior. The SBR is an adaptation of ...
Accelerometers have the advantage of providing objective measures of both physical activity performed at various intensities and of sedentary time. ActiGraph accelerometers are widely used, however with technological advancements new models are periodically released. The GT3X is the most recent model. Although research has shown previous ActiGraph models to ...
Accelerometers worn at the hip are used to assess physical activity, but non-wear can limit such studies. Wearing the monitor on the wrist may enhance compliance, but estimates of physical activity levels may not be comparable between hip worn and wrist worn monitors. Purpose To examine agreement between wrist worn ...
The pattern of physical activity in Hungarian adults might provide information on potential obesity prevention strategies. In preparation for a region assessment of physical activity (PA), placement of an activity monitor were studied in leu of the changes that the NHANES protocol has in the location of the ActiGraph monitors ...
The Physical Activity Questionnaires (PAQ-Children and PAQ-Adolescents) are widely used to assess youth physical activity patterns but a limitation is that they do not provide information about time spent in moderate-to-vigorous physical activity (MVPA). Purpose The purpose of this study was to calibrate in- and out-of-school activity items of the ...
Purpose To examine the accuracy of three measurement devices (ActiGraph GT3x+, ActivPAL, and Sensewear Armband) in assessing sedentary behavior and light-intensity physical activity (PA) against a referent measure of oxygen uptake (Oxycon Mobile). Methods 16 adults (8 males, 8 females) wore the four measurement devices while performing 7 activities (walking at 1.0 mph, 1.5 mph, 2.0 ...
Various sets of prediction equations for the Actigraph have been developed to estimate energy expenditure (EE) in youth, but there is no consensus about the best approach. A set of two 2-regression models (2RM) have been proposed as alternative to traditional single regression models (1RM), but they have not been ...
