Project PANK: Rationale, Design and Baseline Results of a Multidisciplinary School-Based Intervention in Children with Cardiovascular and Metabolic Risk Factors. A Randomized Controlled Trial.

  • Presented on July 3, 2014

Introduction: Atherosclerosis begins in youth and is related to the presence of cardiovascular and metabolic risk factors (CMRF): age, gender, nutrition, physical inactivity, cardiorespiratory fitness (CF), blood pressure (BP), lipids and overweight/obesity. There is strong evidence showing that schools should include nutrition and physical activity (PA) in the curriculum. ...



Relationship Between Objectively Measured Physical Activity and FMS in Children

  • Presented on July 3, 2014

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 ...


Understanding Adolescent Sedentary Behavior Using Accelerometry and Self-Report

  • Presented on July 3, 2014

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 ...


Perceived environment and neighbourhood characteristics: What is their relationship with physical activity of heart disease patients not attending cardiac rehabilitation?

  • Presented on May 21, 2014

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 (...


Free-living accelerometer-determined time spent at or above individualized normal cadence in children by BMI-defined weight status

  • Presented on May 21, 2014

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 ...


Predicting energy expenditure from a wrist-worn ActiGraph GT3X+ accelerometer

  • Presented on May 21, 2014

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. ...


Demonstrating the utility of a person-worn camera to assess multiple behaviors in different populations: Beyond accelerometers and food recalls

  • Presented on May 21, 2014

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 (...


Are newer versions of ActiGraph accelerometers (GT3X+) comparable with older models (7164) in young people, and does the low frequency extension make a difference?

  • Presented on May 21, 2014

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 ...


Beyond the home: Effects of including more than one location on modeled relationships between environment and physical activity

  • Presented on May 21, 2014

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 ...
