IT is widely used for biomechanics and AHRS sensor also be highlighted with small sizedcharacteristics and price competitiveness in the field of motion measurement and analysis of sports. In thispaper, we attach the AHRS to the figure skate shoes to measure the motion data like spin,forward/backward, jump, in/out edge and toe movement. In order to reduce the measurement error, wehave adopted the sensors equipped with Madgwick complementary filtering and also use Euler angle toquaternion conversion to reduce the Gimbal-lock effect. We test and experiment the accuracy andexecution time of the pattern recognition algorithms like PCA, ICA, LDA, SVM to show the recognitionpossibility of it on the basic motions of figure skating from the 9-axis trajectory information which is gathered from AHRS sensor. From the result, PCA, ICA have low accuracy, but LDA, SVM have goodaccuracy to use for recognition of basic motions of figure skating.
