Association between walking speed and age in healthy, free-living individuals using mobile accelerometry--a cross-sectional study.
<h4>Context</h4>Walking speed is a fundamental parameter of human motion and is increasingly considered as an important indicator of individuals' health status.<h4>Objective</h4>To evaluate the relationship of gait parameters, and demographic and physical characteristics...

Collection of demographic data, measurement of physical characteristics (height, weight and blood pressure) and assessment of 7-day, free-living activity parameters using accelerometry and a novel algorithm to measure walking speed. Participants were a median (interquartile range[IQR]) age of 49 (16) years; 45% women; and had a median (IQR) BMI of 26 (5.4).<h4>Main outcome measure</h4>Walking speed.<h4>Results</h4>In this study, the hypothesis that walking speed declines with age was generated using an initial 'open' dataset. This was subsequently validated in a separate 'closed' dataset that showed a decrease of walking speed of -0.0037 m/s per year. This is equivalent to a difference of 1.2 minutes, when walking a distance of 1 km aged 20 compared to 60 years. Associations between walking speed and other participant characteristics (i.e. gender, BMI and blood pressure) were non-significant. BMI was negatively correlated with the number of walking and running steps and longest non-stop distance.<h4>Conclusion</h4>This is the first study using accelerometry which shows an association between walking speed and age in free-living, healthy individuals.
