The summary measure of overall physical activity is lower in older participants and age-related differences in activity are most prominent in the afternoon and evening, which lays the foundation for studies of physical activity and its health consequences.

A robust segmentation technique based on an extension to the traditional fuzzy c-means (FCM) clustering algorithm is proposed and a neighborhood attraction, which is dependent on the relative location and features of neighboring pixels, is shown to improve the segmentation performance dramatically.
The validity and reliability of a novel activity monitor as a measure of walking

The activPAL monitor is a valid and reliable measure of walking in healthy adults and its accuracy is not influenced by walking speed, suggesting it may be a useful device in sports medicine.
