Reliability and Validity of the Cancer Prevention Study-3 Physical Activity Survey Items

  • Published on July 30, 2019

This study examined the test-retest reliability and criterion validity of light (LPA), moderate (MPA), vigorous (VPA), and moderate-to-vigorous (MVPA) physical activity survey items in a subset of participants from a large prospective cohort. Participants included 423 women and 290 men aged 31–72 years in the Cancer Prevention Study-3 (CPS-3). Information on physical activity (...



The redox-dependent regulation of satellite cells following aseptic muscle trauma (SpEED): study protocol for a randomized controlled trial

  • Published on July 31, 2019

Background Muscle satellite cells (SCs) are crucial for muscle regeneration following muscle trauma. Acute skeletal muscle damage results in inflammation and the production of reactive oxygen species (ROS) which may be implicated in SCs activation. Protection of these cells from oxidative damage is essential to ensure sufficient muscle regeneration. The ...


Neuromuscular function of the plantar flexors and predictors of peak power in middle-aged and older males

  • Published on July 30, 2019

Abstract Little evidence exists regarding the contribution of torque and velocity to the age-related decrease in peak power (PP) for the plantar flexors (PFs). A comprehensive assessment of PF neuromuscular function is necessary to elucidate age-related changes, especially between middle-aged and older adults, in order to identify early, age-related decrements. ...


Associations of School Day Sedentary Behavior and Physical Activity With Gross Motor Skills: Use of Compositional Data Analysis

  • Published on July 31, 2019

Background To examine the relationships among school day sedentary times (SED), light physical activity (LPA), and moderate to vigorous physical activity (MVPA) with gross motor skills in children using Compositional Data Analysis. Methods Participants were 409 children (mean age = 8.4 [1.8] y) recruited across 5 low-income schools. Gross motor skills were assessed using the ...


Physical Activity Levels in Peripheral Artery Disease Patients

  • Published on July 29, 2019

Background Increases in daily physical activity levels is recommended for patients with peripheral artery disease (PAD). However, despite this recommendation, little is known about the physical activity patterns of PAD patients. Objective To describe the physical activity patterns of patients with symptomatic peripheral artery (PAD) disease. Methods This cross-sectional study ...


Total energy expenditure assessed by doubly labeled water technique and estimates of physical activity in Mauritian children: analysis by gender and ethnicity

  • Published on July 29, 2019

Background/objectives In the tropical island of Mauritius, the rise in obesity has accelerated in the past decades, and could be contributed by low physical activity and increased sedentary behavior. The study objectives were to generate the first dataset of total energy expenditure (TEE), to estimate physical activity in Mauritian ...


A randomised controlled trial to investigate the use of high-frequency airway oscillations as training to improve dyspnoea in COPD

  • Published on July 29, 2019

Introduction Chronic obstructive pulmonary disease (COPD) is characterised by expiratory flow limitation resulting in symptomatic dyspnoea, sputum retention and ventilation heterogeneity. Changes in breathing mechanics affect the ability of respiratory muscles to respond to the ventilatory demands, increasing the sensation of dyspnoea. A high-frequency airway oscillating device has been developed ...


Influence of air pollution exposure on adolescents’ objectively-measured physical activity and sedentary behavior

  • Published on July 22, 2019

Abstract Although regular physical activity is recommended for health, highly contaminated air exposure acts to the detriment of the benefits produced in individuals. The purpose of the present study was to compare the accelerometer-measured physical activity and sedentary behavior during the whole day, in-school time, out-of-school time, and school breaks ...


Feasibility Trial Evaluation of a Peer Volunteering Active Aging Intervention

  • Published on July 16, 2019

Background ACE (Active, Connected, Engaged) is a theory-informed, pragmatic intervention using peer volunteering support to promote active ageing in socially disengaged, inactive older adults. This study aimed to establish ACE’s feasibility and acceptability. Methods Fifty-four older adults were recruited as either peer volunteers (activators; n = 15) or participants (ACEs; n = 39). ...
