Association between physical activity in daily life and pulmonary function in adult smokers

  • Published on Apr 2016

Objective: To determine whether the level of physical activity in daily life (PADL) is associated with pulmonary function in adult smokers. Methods: We selected 62 adult smokers from among the participants of an epidemiological study conducted in the city of Santos, Brazil. The subjects underwent forced spirometry for pulmonary function assessment. ...


Screening for physical inactivity among adults: the value of distance walked in the six-minute walk test. A cross-sectional diagnostic study

  • Published on 2016

Context and Objectives: Accelerometry provides objective measurement of physical activity levels, but is unfeasible in clinical practice. Thus, we aimed to identify physical fitness tests capable of predicting physical inactivity among adults. Design and Setting: Diagnostic test study developed at a university laboratory and a diagnostic clinic. Methods: 188 asymptomatic subjects ...


Use of combined method, accelerometer and international physical activity questionnaire, to determinate occurence of physical inactivity in adults

  • Published on 2017

Aim: Evaluate and compare the proportion of Physical inactivity (PI) and associated factors by IPAQ questionnaire, triaxial accelerometry and the combination of both. Adults aged 18 years were enrolled (n = 250). Methods: We considered PI as < 600 MET-min/wk in the IPAQ total score, < 150 min/wk of moderate-to-vigorous physical activity in 7 ...


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 ...



Preschoolers' Physical Activity Participation Across a Yearlong Mastery-Motivational Climate Intervention

  • Published on Sep 2017

Purpose: This study sought to determine how children's participation in physical activity during a mastery-motivational climate changed during a 20-week intervention and to compare it to children's free-play activity during a typical day at their local day-care facility. Method: Twelve 4-year-old children participated in a mastery-motivational climate physical activity program ...


Predictors of Physical Activity After Gastric Bypass-a Prospective Study

  • Published on Aug 2017

Background: Most patients do not meet the recommended level of physical activity after bariatric surgery, and psychological factors underlying postoperative physical activity remain poorly understood. This study aimed at identifying self-regulatory predictors of physical activity after bariatric surgery. Methods: Questionnaire data including self-regulation variables and the short-version of the International ...


Objectively measured physical activity patterns, sedentary time and parent-reported screen-time across the day in four-year-old Swedish children.

  • Published on Aug 2017

Background: Physical activity (PA) improves health outcomes accumulating evidence suggests that sedentary time (ST), especially parent-reported screen-time, is associated with negative health outcomes in children. The aim of the present study is to describe levels and patterns of PA and ST across the day and week and activity pattern differences ...



Validity of treadmill- and track-based individual calibration methods for estimating free-living walking speed and VO2 using the Actigraph accelerometer

  • Published on Nov 25, 2015

Background: For many patients clinical prescription of walking will be beneficial to health and accelerometers can be used to monitor their walking intensity, frequency and duration over many days. Walking intensity should include establishment of individual specific accelerometer count, walking speed and energy expenditure (VO2) relationships and this can be ...
