Impact of reduced sampling rate on accelerometer-based physical activity monitoring and machine learning activity classification
Purpose: Lowering the sampling rate of accelerometers in physical activity research can dramatically increase study monitoring periods through longer battery life; however, the effect of reduced sampling rate on activity metric validity is poorly documented. We therefore aimed to assess the effect of reduced sampling rate on measuring physical activity both overall and by specific behavior types.
Methods: Healthy adults wore sets of two Axivity AX...Expand abstract
