Abstract

Accelerometer data have traditionally been expressed as time spent in physical activity intensities using thresholds or cut points. A move away from cut-points is recommended because of the ‘cut-point conundrum’ where different thresholds can lead to vastly different estimates of physical activity (see next page), lack of comparability between devices, and inability to capture the multidimensional nature of physical activity. Despite the emergence of alternative approaches, use of cut-points is still widespread. There is therefore a need to de-mystify alternatives to cut-point analyses and provide guidance for researchers and practitioners.
