Sedentary Behavior, Physical Activity, and Bone Health in Postmenopausal Women

  • Presented on May 28, 2014

Background: Post-menopausal women exhibit lower bone mineral density (BMD) and current health guidelines highlight the potential importance of reducing sedentary behavior (SB) to mitigate bone loss in this segment of the female population. Purpose: To determine if bone health status at the femoral neck (FN) and lumbar spine (LS) can ...


Effects of Moderate Intensity Walking on Daily and 3-Hour Dietary Intake

  • Presented on May 28, 2014

Background: The inter-individual variability in the effectiveness of structured exercise to achieve expected levels of weight loss or maintenance appears to be due in part to individual differences in behavioral responses that increase energy intake; however, the influence of acute exercise on dietary intake following exercise remains incompletely characterized. ...


Calibration and Validation of a Wrist Worn Accelerometer for 8 to 12 Year Old Children

  • Presented on May 29, 2014

Purpose: Currently, there are no methods to distill information from the most widely used wrist-mounted accelerometer. A field-based calibration study was conducted in order to determine cut point thresholds for this wrist-mounted accelerometer in children aged 8-12 years. Methods: Forty-five children (25 developmental; 20 cross validation) aged 8-12 years, performed up to ...


Development Of Wrist And Ankle Cut-points For Youth With The ActiGraph Accelerometer

  • Presented on May 29, 2014

Purpose: The purpose of this study was to develop and validate physical activity (PA) cut-points for wrist (WR) and ankle (AK) accelerometer placements in youth. Methods: : For cut-point development 84 girls and 97 boys (mean ± SD; age, 12.0 ± 1.5 yrs) completed 30 min of lying rest and two to seven structured activities (from a list ...



Trajectories of Objectively Measured Physical Activity in Free-Living Older Men

  • Published on July 1, 2014

Background: The steep decline in physical activity (PA) among the oldest old is not well understood; there is little information about the patterns of change in PA and sedentary behaviour (SB) in older people. Longitudinal data on objectively measured PA data can give insights about how PA and sedentary behaviour (...


Nitrogen Balance in Older Individuals in Energy Balance Depends on Timing of Protein Intake

  • Published on Oct. 2010

Abstract: To explore whether nitrogen retention can differ on an isonitrogenous diet by changing when protein is consumed, we performed a short-term study in older individuals (64.5 ± 2.0 years) performing daily exercise while in energy balance. Participants consumed an isonitrogenous–isocaloric diet with the timing of a protein or carbohydrate beverage after ...


Daily physical activity and physical function in adult maintenance hemodialysis patients

  • Added on July 7, 2014

Abstract: Maintenance hemodialysis (MHD) patients reportedly display reduced daily physical activity (DPA) and physical performance. Low daily physical activity and decreased physical performance are each associated with worse outcomes in chronic kidney disease patients. Although daily physical activity and physical performance might be expected to be related, few studies have ...


Relation between anxiety, depression, and physical activity and performance in maintenance hemodialysis patients.

  • Published on July 2014

Objective: Maintenance hemodialysis (MHD) patients have a high prevalence of anxiety and depression and decreased daily physical activity (DPA) and exercise capacity. Because affective disorders may affect DPA and physical performance, we investigated possible relationships between anxiety or depression and DPA and physical performance in relatively healthy MHD patients. Design ...


Directly-Measured Physical Activity Predicts Re-Hospitalization Within Thirty Days Following Discharge For A COPD Exacerbation

  • Presented on May 19, 2014

Background: Lower levels of physical activity are related to increased health care utilization and mortality risk in patients with COPD. Since re-hospitalization within 30 days following discharge for a COPD exacerbation is considered an important outcome, we evaluated the relationship between physical activity and 30-day readmission. Methods: Thirty-four patients discharged following ...
