Background: Aging is associated with detrimental changes in physical function (PF), leading to frailty and disability. Physical activity (PA) has been deemed a best buy for public health. Currently there is limited data on the relationships between PA assessed with body worn sensors and various objective measures of PF. Purpose: ...
Background: It has been reported that mother-daughter relationship can influence psychosocial variables such as physical activity (PA) self-efficacy in Caucasian girls. Currently, there is very little data on the impact of African-American girls’ perception of their relationship with their mother and psychosocial variables. Purpose: To examine the association ...
Background: The development of childhood obesity has been linked to chronic energy surplus due to poor dietary habits and inadequate physical activity (PA). Researchers have suggested that a sustained increase in moderate-to-vigorous PA (MVPA) can help reduce the prevalence of obesity by correcting for the energy surplus. Changes in US ...
Background: Sedentary behavior has been shown to be inversely associated with markers of insulin sensitivity and cardiometabolic health in middle-aged and older adults, independent of moderate-to-vigorous physical activity (MVPA). Low cardiorespiratory fitness (CRF) is an independent risk factor for cardiovascular disease (CVD) mortality, yet it is unknown whether CRF infl...
Background: Accelerometers and global positioning system (GPS) units to monitor participants’ activity allow for a dynamic spatial examination of the locations where physical activity occurs. The application of spatial clustering analysis to these geographically linked physical activity data may provide a better understanding of how moderate-to-vigorous physical activity (MVPA) concentrates ...
Background: Despite a growing body of research indicating that dog walking contributes to meeting physical activity (PA) recommendations, a key limitation of this literature is the use of self-report measures of dog walking and overall PA. Purpose: The purpose of this pilot study was to use accelerometry to characterize the ...
Purpose: This study described the association of accelerometer-determined physical activity and sedentary behavior with all-cause mortality using a nationally representative sample from the United States. Methods: Using 2003-04 National Health and Nutrition Examination Survey (NHANES) data, 4000 adults at least 18 years wore an ActiGraph accelerometer for one week, providing at least 3 ...
Background: Physical activity and fitness are essential to improve or maintain health particularly among elders, but rarely evaluated in community-based programs. Purpose: We tested the following hypotheses: 1) steps/day and time engaged in moderate to vigorous physical activity (MVPA) will be below recommended levels, and 2) steps/day and MVPA will ...
Background: Comparison between self-reported and objective assessment of physical activity (PA) and sedentary time among Hispanic elders in Puerto Rico has not been evaluated. Purpose: We tested the following hypotheses: 1) moderate to vigorous PA (MVPA) behavior will be higher and sedentary time lower with self-report compared with objective assessment, 2) sedentary ...
Background: Participation in moderate physical activity (PA) as a means of eliciting health-related benefits is consistently recommended through the 2008 Physical Activity Guidelines and the ACSM-AHA Physical Activity Recommendations. Many try to meet this requirement by participating in PA that fit both their functional abilities and personality. However, quantifying the intensity ...
