BACKGROUND Population-specific accelerometer cut-points are required to accurately determine the accumulation of physical activity of various intensities. OBJECTIVES A calibration study was conducted (i) to determine the cut-points for the ActiGraph GT3X+, non-dominant, wrist-mounted accelerometer in children aged 8-12 years and (ii) to compare classification accuracies among the accelerometer's three axes and vector magnitude (VM) values. METHODS Forty-five children aged 8-12 years… CONTINUE READING
