Accuracy of Inclinometer Functions of the activPAL and ActiGraph GT3X+: A Focus on Physical Activity

Highlights • The activPAL was reasonably accurate for detecting sitting, standing, and stepping activity. • The activPAL was more accurate than the ActiGraph GT3X+ in both sitting and standing activities except the activity of stationary biking. • Both ActiGraph GT3X+ and the activPAL were also fair...

Description
Summary:Highlights • The activPAL was reasonably accurate for detecting sitting, standing, and stepping activity. • The activPAL was more accurate than the ActiGraph GT3X+ in both sitting and standing activities except the activity of stationary biking. • Both ActiGraph GT3X+ and the activPAL were also fairly accurate for classifying stepping activity when the stepping activity was determined by the formula created by 0.7 step/sec threshold. • It is expected that the result of the study would contribute to performing movement pattern analyses and health promotion research for posture classification.
