Observational Study of a Wearable Sensor and Smartphone Application Supporting Unsupervised Exercises to Assess Pain and Stiffness

  • Published on Sept. 2018

Background: Evaluation of pain and stiffness in patients with arthritis is largely based on participants retrospectively reporting their self-perceived pain/stiffness. This is subjective and may not accurately reflect the true impact of therapeutic interventions. We now have access to sensor-based systems to continuously capture objective information regarding movement and ...




Moderate intensity physical activity associates with CSF biomarkers in a cohort at risk for Alzheimer’s disease

  • Published on Feb 6, 2018

Introduction: Alzheimer's disease (AD) is characterized by the presence of amyloid β (Aβ) plaques, neurofibrillary tangles, and neurodegeneration, evidence of which may be detected in vivo via cerebrospinal fluid (CSF) sampling. Physical activity (PA) has emerged as a possible modifier of these AD-related pathological changes. Consequently, the aim of this study ...


Physical Activity, Sedentary Behavior, and Inflammatory and Hemostatic Markers in Men

  • Published on Mar 2017

Purpose: This study aimed to determine whether higher levels of physical activity (PA) and less sedentary behavior (SB) are associated with less inflammation, indicated by inflammatory and hemostatic biomarkers, in older men. Methods: A cross-sectional study of 1139 men, from the British Regional Heart Study (mean ± SD age = 78 ± 5 yr), and longitudinal ...


Light-Intensity Physical Activity and Cardiometabolic Biomarkers in US Adolescents

  • Published on August 9, 2013

Background: The minimal physical activity intensity that would confer health benefits among adolescents is unknown. The purpose of this study was to examine the associations of accelerometer-derived light-intensity (split into low and high) physical activity, and moderate- to vigorous-intensity physical activity with cardiometabolic biomarkers in a large population-based sample. Methods: ...


Reallocating time to sleep, sedentary behaviors, or active behaviors: associations with cardiovascular disease risk biomarkers, NHANES 2005-2006.

  • Published on Jan. 17, 2014

Abstract: Sleep and sedentary and active behaviors are linked to cardiovascular disease risk biomarkers, and across a 24-hour day, increasing time in 1 behavior requires decreasing time in another. We explored associations of reallocating time to sleep, sedentary behavior, or active behaviors with biomarkers. Data (n = 2,185 full sample; n = 923 fasting subanalyses) ...


Muscular fitness, fatness and inflammatory biomarkers in adolescents

  • Published on July 2013

Commentary: Rona Macniven, Prevention Research Collaboration, University of Sydney Adolescence is known to be a period of time where physical activity levels decline and weight increases so it is therefore an optimum opportunity for health interventions. This international study looked at the science around inflammatory biomarkers present in blood samples ...


Self-reported Versus Objectively Measured Physical Activity & Cardiometabolic Biomarkers Among Youth in NHANES

  • Added on June 15, 2012

Purpose To compare associations between objective and subjective measures of moderate to vigorous physical activity (MVPA) & cardiometabolic biomarkers. Methods 2174 (1110 boys) youth (12-19 years) from the 2003-6 NHANES combined surveys with self-reported MVPA (SRMVPA) in the previous 30 days & four 10-hour days of accelerometry MVPA (AMVPA) (Actigraph 7164) were included. The ...


Sedentary Time and Cardio-Metabolic Biomarkers in US Adults: NHANES 2003–06

  • Published on January 11, 2011

Aims Prolonged sedentary time is ubiquitous in developed economies and is associated with an adverse cardio-metabolic risk profile and premature mortality. This study examined the associations of objectively assessed sedentary time and breaks (interruptions) in sedentary time with continuous cardio-metabolic and inflammatory risk biomarkers, and whether these associations varied by ...
