The distribution of activPAL postural and stepping classifications within ActiGraph activity classifications (2017)
Presentation / Conference
Clarke-Cornwell, A., Cook, P., & Granat, M. (2017, June). The distribution of activPAL postural and stepping classifications within ActiGraph activity classifications. Presented at International Conference on Ambulatory Monitoring of Physical Activity and Movement, Bethesda, USA

Objective: Guidelines of physical activity (PA) and sedentary behaviour (SB) are dependent on how we define and quantify physical behaviour. It is therefore important to understand the validity of objective measures of PA and SB. This study aimed to...

The influence of dog ownership on objective measures of free-living physical activity and sedentary behaviour in community-dwelling older adults : a longitudinal case-controlled study (2017)
Journal Article

Background: There is some evidence to suggest that dog ownership may improve physical activity (PA) among
older adults, but to date, studies examining this, have either depended on self-report or incomplete datasets due to
the type of activity moni... Read More about The influence of dog ownership on objective measures of free-living physical activity and sedentary behaviour in community-dwelling older adults : a longitudinal case-controlled study.

Total hip arthroplasty improves pain and function but not physical activity (2017)
Journal Article
Jeldi, A., Deakin, A., Allen, D., Granat, M., Grant, M., & Stansfield, B. (2017). Total hip arthroplasty improves pain and function but not physical activity. Journal of Arthroplasty, 32(7), 2191-2198. https://doi.org/10.1016/j.arth.2017.02.002

Background:
People with hip osteoarthritis are likely to limit physical activity (PA) engagement due to
pain and lack of function. Total hip arthroplasty (THA) reduces pain and improves function,
potentially allowing increased PA. PA of THA patie... Read More about Total hip arthroplasty improves pain and function but not physical activity.

Large scale population assessment of physical activity using wrist worn accelerometers: The UK Biobank Study (2017)
Journal Article

BACKGROUND: Physical activity has not been objectively measured in prospective cohorts with sufficiently large numbers to reliably detect associations with multiple health outcomes. Technological advances now make this possible. We describe the metho... Read More about Large scale population assessment of physical activity using wrist worn accelerometers: The UK Biobank Study.

A technique to record the sedentary to walk movement during free living mobility : a comparison of healthy and stroke populations (2016)
Journal Article

Background


Hesitation between moving from a sedentary posture (lying/sitting) to walking is a characteristic of
mobility impaired individuals, as identified from laboratory studies. Knowing the extent to which this
hesitation occurs during ev... Read More about A technique to record the sedentary to walk movement during free living mobility : a comparison of healthy and stroke populations.

Differentiating sitting and lying using a thigh-worn accelerometer (2016)

Visualization is commonly used in the interpretation of physical behavior (PB) data, either in conjunction with or as precursor to formal analysis. Effective representations of the data can enable the identification of patterns of behavior, and how t... Read More about Visualization of sedentary behavior using an event- based approach.

Empirically derived cut-points for sedentary behaviour for weekdays and weekends : are we sitting differently? (2015)
Presentation / Conference
Clarke-Cornwell, A., Farragher, T., Cook, P., Dugdill, L., & Granat, M. (2015, June). Empirically derived cut-points for sedentary behaviour for weekdays and weekends : are we sitting differently?. Presented at International Conference on Ambulatory Monitoring of Physical Activity and Movement, Limerick, Ireland

Introduction: Sedentary behaviour (SB) is associated with many adverse health outcomes. Studies that have used accelerometers to define sedentary time usually adopt a <100 counts per minute (cpm) threshold for classifying SB; however, this cut-poi...

Quantifying the cadence of free-living walking using event-based analysis (2015)
Journal Article
Granat, M., Clarke, C., Holdsworth, R., Stansfield, B., & Dall, P. (2015). Quantifying the cadence of free-living walking using event-based analysis. Gait & Posture, 42(1), 85-90. https://doi.org/10.1016/j.gaitpost.2015.04.012

Purpose: Free-living walking occurs over a wide range of durations and intensities (cadence). Therefore,
its characterisation requires a full description of the distribution of duration and cadence of these
walking events. The aim was to use event-... Read More about Quantifying the cadence of free-living walking using event-based analysis.
