Changing physical activity behavior for people with multiple sclerosis: protocol of a randomized controlled feasibility trial (iStep-MS)

  • Published on Nov 15, 2017

Introduction: Although physical activity may reduce disease burden, fatigue and disability, and improve quality of life among people with multiple sclerosis (MS), many people with MS are physically inactive and spend significant time in sedentary behavior. Behavior change interventions may assist people with MS to increase physical activity and reduce ...


Effect of ActiGraph’s low frequency extension for estimating steps and physical activity intensity

  • Published on Nov 20, 2017

Abstract: This study examined the effects of the ActiGraph's (AG) low-frequency extension (LFE) filter on steps and physical activity classification in the free-living environment. Thirty-four African-American women (age, 24.5±5.2 years; BMI, 24.9±4.5 kg/m2) had daily activity measured simultaneously with an AG-GT3X+ accelerometer and a New Lifestyles NL-800 pedometer for seven ...


Different autonomic responses to occupational and leisure time physical activities among blue-collar workers

  • Published on Nov 24, 2017

Purpose: The differential effect of occupational and leisure time physical activity on cardiovascular health is termed the physical activity health paradox. Cardiac autonomic modulation could bring insights about the underlying mechanism behind this differential effect. The aim was to compare heart rate variability (HRV) during different activities (sitting, standing and ...



Changes in Physical Activities and Body Composition after Roux-Y Gastric Bypass Surgery

  • Published on December 22, 2017

PURPOSE Given the importance of physical activities for health outcomes, it is still unclear whether bariatric surgery per se and the standard care after surgery would result in an increase of physical activity level. This study aimed to determine physical activities preoperatively and at 6 and 12 months postoperatively among female patients ...



The role of moderate-to-vigorous physical activity in mediating the relationship between central adiposity and immunometabolic profile in postmenopausal women.

  • Published on Aug 2017

Objectives: To analyze the role of moderate-to-vigorous physical activity (MVPA) in mediating the relationship between central adiposity and immune and metabolic profile in postmenopausal women. Materials and Methods: Cross-sectional study comprising 49 postmenopausal women (aged 59.26 ± 8.32 years) without regular physical exercise practice. Body composition was measured by dual-energy X-ray absorptiometry. Fasting blood ...


Calibration of the global physical activity questionnaire to Accelerometry measured physical activity and sedentary behavior

  • Published on March 27, 2018

Background Self-report questionnaires are a valuable method of physical activity measurement in public health research; however, accuracy is often lacking. The purpose of this study is to improve the validity of the Global Physical Activity Questionnaire by calibrating it to 7 days of accelerometer measured physical activity and sedentary behavior. Methods ...


Change in Physical Activity During Active Treatment of Cardiac Patients

  • Published on April 2017

Abstract: Sedentary secular, domestic, and recreational behaviour is a major risk factor (RF) for cardiovascular disease (CVD). This study examines the quality of at-home physical activity (PA) and how it relates to physical fitness (PF) before and during 12 weeks of supervised cardiac rehabilitation (CR) in a group of medically referred ...
