Comparison of Three Generations of ActiGraph™ Activity Monitors in Children and Adolescents

  • Published on 2012

In this study, we evaluated agreement among three generations of ActiGraph™ accelerometers in children and adolescents. Twenty-nine participants (mean age = 14.2 ± 3.0 years) completed two laboratory-based activity sessions, each lasting 60 min. During each session, participants concurrently wore three different models of the ActiGraph™ accelerometers (GT1M, GT3X, GT3X+). Agreement among ...


Intermonitor Variability of GT3X Accelerometer

  • Added on July 27, 2012

The main purpose of this study was to assess the inter-monitor reliability of the tri-axial GT3X Actigraph accelerometer over a range of physical activities (PA). This device collects motion data on each of the vertical (Y), horizontal right-left (X), and horizontal front-back (Z) axes and also calculates the vector ...


Girls' Physical Activity Levels During Organized Sports in Australia

  • Added on July 26, 2012

Purpose The primary aim of this study was to objectively examine physical activity (PA) levels of girls during organized sport (OS), and to compare the levels between games and practices for the same participants. Secondary aims of this study were to document lesson context and coach behavior during practices and ...


Physical Activity Counselling and Exercise Referral Increases Total Physical Activity in Long Term Unemployed Individuals: A Controlled Accelerometer Trial

  • Added on July 19, 2012

Introduction Physical activity is seen as an integral component of a healthy lifestyle and has the potential to produce significant health benefits amongst individuals (Pedersen & Saltin 2006). It therefore plays a major role in the field of public health and primary prevention. Compared to the general population, unemployed persons show ...


How Important is the Use of a Logbook in Addition to Accelerometer to Assess the Proportion of Insufficiently Active 13-year-old Girls?

  • Added on July 7, 2012

Introduction It is strongly recommended to use objective measurements for the assessment of physical activity among children and adolescents. However, as some activities such as bicycling/inline skating/scooter are incorrectly recorded by accelerometer, assisting methods are needed to obtain correct data. The aim of the study was to examine ...


Altered Circadian Rhythmicity in Blood Pressure with Spinal Cord Injury is Not Explained by Differences in Physical Activity

  • Added on July 7, 2012

Introduction Individuals with spinal cord injury (SCI) demonstrate attenuation or absence of nocturnal reductions in blood pressure (BP) and heart rate (HR) (Rosado-Rivera et al., 2011; J Spinal Cord Med, 34, 395). Diminished rhythmicity is associated with increased incidence of cardiovascular disease and mortality (Verdecchia et al., 1993; Circ, 88; 986). Differences in the levels of ...





Reduced Postoperative Physical Activity of Children with Congenital Heart Diseases

  • Added on July 7, 2012

Background Children with congenital heart disease (CHD) have a reduced exercise capacity. Studies suggest that prolonged hospitalization might contribute to deconditioning in exercise capacity. This study examined the postoperative physical activity among children with CHD after a hospital stay. Methods 34 children and adolescents with CHD (21 girls, 8.0 years [IQ: 6.0-11.0 years]) ...
