Background
Accurate objective assessment of sedentary and physical activity behaviours during childhood is integral to the understanding of their relation to later health outcomes, as well as to documenting the frequency and distribution of physical activity within a population.
Purpose
To calibrate the Actigraph GT1M accelerometer, using energy expenditure (...
Background
Low physical activity (PA) is linked to cancer and other diseases prevalent in racial/ethnic minorities and low-income populations. This study evaluated the PA questionnaire (PAQ) used in the Southern Cohort Community Study, a prospective investigation of health disparities between African-American and white adults.
Methods
The PAQ was administered ...
Introduction
Sedentary behavior (SB) is directly associated with a greater risk of death from cardiovascular problems, cancer and all causes. Moreover, SB is directly associated with obesity in children. This study examined whether there was a significant seasonal variation in objectively measured SB in Portuguese youth across five months of ...
Introduction
There is concern that preschool children are not physically active enough to benefit health, yet few interventions have attempted to increase physical activity (PA) in this population. This study aimed to investigate the effectiveness of a 6-week school based Active Play intervention on children’s moderate-to-vigorous physical activity (MVPA) ...
Introduction
Feedback and monitoring physical activity (PA) may have a role decreasing sedentary behavior. The aim of this study was to test the effectiveness of a Polar Activity Computer (FA20, Polar Electro Oy, Kempele, Finland) in increasing PA in daily life over 6 month.
Method
50 volunteer healthy subjects were randomly assigned ...
Introduction
The Incidental and Planned Activity Questionnaire (IPAQ), renamed to be IPEQ, is a self-report short questionnaire that was developed for use in ageing research. The questionnaire asks about an average week frequency and duration (closed categories) of planned exercise, walking for exercise, walking to places and chores inside and ...
Introduction
Accurate objective methods for the assessment of sedentary behavior are crucial for population monitoring and evaluation of public health strategies for preventing childhood obesity. Actigraph accelerometers are a commonly used objective physical activity measurement tool. It is hypothesized that accelerometers may also provide a valid method for assessing children’...
Introduction
Recent research shows that too much sitting has negative effects on health and well-being independently from people meeting the current physical activity (PA) recommendations [1]. However sedentary behavior (SB) is still an understudied topic. The aim of this study was to objectively investigate the time spent in sedentary and PA ...
The number of days of pedometer or accelerometer data needed to reliably assess physical activity (PA) is important for research that examines the relationship with health. While this important research has been completed in young to middle-aged adults, data is lacking in older adults. Further, data determining the number of ...
Introduction Accelerometer data provide reliable, valid, and stable measures of physical activity, and also allow for the estimation of sedentary time. Furthermore, as data are date and time-stamped, the outcomes of interventions targeting these behaviors can be explored beyond simple average of change.
