Introduction: Despite known benefits of regular physical activity for health and well-being, many studies suggest that levels of physical activity in young people are low, with the majority of youth not meeting the minimum 60-minute daily moderate to vigorous PA (MVPA) guideline for health. The purpose of this study was ...
Introduction: Little objective data have examined the effectiveness of physical education (PE) in schools to augment students’ physical activity (PA) level. We believe that PE is one of the most important methods to increase PA among school aged children. Most studies have shown that students spend less than 50% of PE ...
Introductions: Physical inactivity is associated with a higher risk of obesity, type II diabetes, hypertension, stroke, psychological problems, and some cancers (1). Currently there are no recommendations in Ireland for sedentary behaviour (SB), however, Australian guidelines recommend <2hours a day in sedentary screen time (ST) behaviour (2). Purpose: The purpose of ...
Purpose: Emerging literature suggests that the environment can impact physical activity levels. To date, however, very little is known about the role of the environment with individuals living with heart disease. The purpose of this study was to objectively measure the physical activity (PA) of individuals with coronary heart disease (...
Purpose: The study of children’s free-living cadence (steps/min) is possible using accelerometers capable of recording minute-by-minute step data monitored over several days. The objective of this study was to determine free-living accelerometer- determined time at or above GAITRite-assessed individualized normal cadence in children categorized by BMI as normal ...
Purpose: To examine the validity of a wrist-worn accelerometer for predicting energy expenditure in adults. Methods: Thirty-eight adults (Mage: 35.7 ± 12.2; 54% male) participated in up to 6 prescribed activities of daily living (e.g. washing dishes, sweeping), and walking (slow and brisk), while wearing an ActiGraph GT3X+ accelerometer on the non-dominant wrist. ...
Purpose: To provide objective measures of physical activity (PA) and eating behaviors (EB) using a single device. Person-worn cameras (PWC) offer the opportunity to classify and characterize multiple concurrent activities and their contexts, simultaneously; allowing for the objective classification of contextual and time-specific activities. Methods: Two distinct populations, overweight females (...
Purpose: Data comparability is an important question in longitudinal studies using different models of accelerometers to measure physical activity. Although studies have been done with adults to compare 7164 and GT3X+ Actigraph accelerometers, comparability in youth has not been demonstrated. The purpose of this study was to determine whether the 7164 ...
Purpose: The dominant methodology for assessing the effects of environment on physical activity focuses on the home environment. However physical activity may occur throughout the day in other locations. These environments may play a role in influencing amount of physical activity conducted, and should be considered. Methods: Eight studies using ...
Purpose: To examine relationships between parent perceived neighborhood recreational environment and physical activity (PA) in adolescents. Perceived diversity and proximity of recreation facilities is a core component of activity friendly neighborhood environments which may contribute to youth PA. Methods: Participants (N=928, mean age 14.1± 1.4 years old, with 50.4% girls, 33.4 non-white/Hispanic) were ...
