Abstract: In recent years, the “Fitbit” activity monitor has been used in numerous studies on physical activity and to promote lifestyle changes by increasing daily walking. In addition, the Fitbit is frequently used by people in free-living situations to monitor daily step counts. To date, limited studies have examined the ...
Purpose: To assess the criterion validity and responsiveness of the Incidental and Planned Exercise Questionnaire (IPEQ), specifically developed for aging research. Methods: Community-dwelling older adults (n=318, mean age 73.2 years) who participated in a trial investigating the effect of walking program on falls. At baseline a sub-sample (n=177) also wore an ...
Objective: The correction to the prevalence of the physical inactive in a 2009-10 Chilean National Health Survey (NHS) through the use of accelerometers. Methods: Population older than 15 years old were recruited from different educational levels of the urban area of Santiago-Chile, who had answered the GPAQ ítem during 2009-10 NHS. ...
Purpose: There is considerable debate about the possibility of physical activity compensation. This study examined whether increased levels in physical activity and/or sedentary behaviour on one day were predictive of lower levels in these behaviours the following day (compensatory mechanisms) among children. Methods: Two hundred and forty-eight children (121 boys, 127 ...
Aim: Research conducted on the general population indicates self-reported measures of physical activity and sedentary behaviour are inaccurate, however it is not clear if this also applies to cancer survivors. The aim of this study was to compare accelerometer-based and self-reported measures of moderate- to vigorous-intensity physical activity (MVPA) and ...
Background: Multicomponent school-based interventions have the potential to reduce the age-related decline in adolescents‘ physical activity (PA). Studies on the effect of school environment interventions have reported varying results. Purpose: To assess the effectiveness of a multicomponent environmental school-based intervention, designed to reduce the age-related decline in PA among adolescents. ...
Purpose: Research on physical activity (PA) in people with heart disease tends to emphasize intrapersonal correlates while largely ignoring the potential importance of higher-level correlates within the social ecological model. Thus, the purpose of this study was to determine the relative importance of several social ecological correlates in predicting whether ...
Background and Aim: Mindfulness training can be an effective strategy to optimize lifestyle behaviors. The aim of this study was to evaluate the effectiveness of a worksite mindfulness-based multi-component intervention on vigorous physical activity in leisure time and sedentary behavior at work. Methods: In a randomized controlled trial design (n=257), 129 ...
Background: Moderate-to-vigorous physical activity (MVPA), and more recently, sedentary behaviour, have well recognised health consequences. However, academic sequelae are less well understood. Some educators assert that promoting MVPA and discouraging sedentary behaviours in schools is important to maximise academic outcomes. Aim: To examine associations between MVPA, sedentary behaviour and academic ...
Introduction: South Asian (SA) school-aged children are reported to be less active than White Europeans, which may contribute to poor current and/or future health. However, research in pre-schoolers is scarce. This study examined ethnic differences in objectively assessed physical activity (PA) and sedentary time of pre-schoolers from a multi-ethnic ...
