Evaluation of Wrist Accelerometer Cut-Points for Classifying Physical Activity Intensity in Youth.
Frontiers in Digital Health(2022)
摘要
Published ActiGraph cut-points for the wrist, developed specifically for school-aged youth, do not provide acceptable classification accuracy for estimating daily time spent in light, moderate, and vigorous intensity physical activity. The development and deployment of more robust accelerometer data reduction methods such as functional data analysis and machine learning approaches continues to be a research priority.
