Daily sedentary time and physical activity as assessed by accelerometry and their correlates in older adults

  • Published on February 18, 2019

Background Higher physical activity is associated with lower chronic disease risk among older adults. However, less is known about the optimal balance between daily physical activity and sedentary time and their correlates among older adults. We described objectively measured physical activity patterns using 7 day hip-accelerometry and assessed its correlates in ...


Feasibility Trial Evaluation of a Peer Volunteering Active Aging Intervention: ACE (Active, Connected, Engaged)

  • Published on February 19, 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). ...


Is older adults’ physical activity during transport compensated during other activities? Comparing 4 study cohorts using GPS and accelerometer data

  • Published on March, 2019

Introduction Promoting active transport offers the potential to increase population physical activity levels. Compensation theories state that above-average physical activity in one activity is compensated in later activities; a mechanism that results in stable levels of total physical activity. Little is known about possible compensation of transport physical activity among ...


Physical Activity Level is Associated with Higher Brain Volume of Elderly: E-BRAIN Project Results

  • Presented on Oct 5, 2018

Introduction: Elderly people present a decrease in the volume of brain structures (VBS). Thus, interventions that promote VBS increase should be emphasized in this population. Studies that analyzed the relationship between moderate-vigorous physical activity (MVPA) and VBS measurements were limited to assessing few structures (hippocampus, total brain volume, gray matter), ...


Demographic and clinical correlates of accelerometer assessed physical activity and sedentary time in lung cancer survivors

  • Published on Mar 2018

Objective: To determine demographic and clinical correlates of accelerometer assessed physical activity and sedentary time among a population-based sample of lung cancer survivors. Methods: Lung cancer survivors in Southern Alberta, Canada (N = 527) were invited to complete a mailed survey assessing socio-demographics and wear an Actigraph® GT3X+ accelerometer for 7 days. ...





Cardiorespiratory Reference Data in Older Adults: The Generation 100 Study

  • Published on Nov 2017

Purpose: Cardiorespiratory fitness (CRF) is regarded a clinical vital sign, and accurate reference values for all age groups are essential. Little data exist on CRF and cardiorespiratory function in older adults. The aim of this study was to provide normative values for CRF and cardiorespiratory function in older adults, including ...


Minimum performance on clinical tests of physical function to predict walking 6000 steps/day in knee osteoarthritis: An observational study.

  • Published on Oct 17, 2017

Objective: Evidence of physical function difficulties, such as difficulty rising from a chair, may limit daily walking for people with knee osteoarthritis (OA). The purpose of this study was to identify minimum performance thresholds on clinical tests of physical function predictive to walk ≥6000 steps/day. This benchmark is known to ...
