<p>The purpose of this study was to evaluate a drop-jump measurement method involving an inertial measurement unit (IMU), by calculating evaluation items using the IMU, and comparing the calculated values with the values measured using a mat switch. Nineteen healthy university students were recruited for the study and were asked to perform a drop jump from a height of 0.3 m. The jump was performed on a mat switch and the participants wore a waist pouch containing an IMU on the posterior side of their waist. The sensor coordinate system acceleration was converted to global coordinate system acceleration by using Madgwick AHRS, and linear acceleration and linear velocity were calculated by removing the effect of gravity acceleration in order to optimize the timing of the drop-jump ground contact and takeoff by setting a threshold. The ground contact time, flight time, and drop-jump index calculated using the threshold set in this study showed “Very high correlation”, as determined by Pearson's correlation coefficient, with the measured values obtained using the mat switch. Therefore, the drop-jump measurement method involving an IMU in this study was found to be capable of evaluating the performance of drop jumps with the same level of accuracy as the measurement method involving a mat switch.</p>
