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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Introduction
Regular physical activity (PA) in older adults is critically important to ensure healthy aging. The link between PA and prevention of disease, maintenance of independence, and improved quality of life is supported by strong evidence. However, there is a lack of data on population levels of PA among older ...
Introduction
Project FFAB is an exploratory controlled before and after study of the effects of a practical and engaging low-volume high-intensity training (HIT) intervention on cardio-metabolic risk markers. The extent to which adaptations to HIT can be maintained is unknown (Gibala & McGee, 2008). We aimed to evaluate the maintenance of ...
Introduction
Relapse in the first 3-5 years following weight loss is a common problem in obesity management (Ross, 2009). The extent to which physiological (Jackman et al., 2008) vs behavioural adaptations contribute to weight loss relapse is not clearly understood. Moreover, there is some indication that an ‘energy gap’ or leading to ...
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]) ...
