碩士 === 樹德科技大學 === 資訊工程系碩士班 === 103 === Objective: The purpose of this study was to investigate the Rugby players play in cell technology floor action, will kicking and high-kick the difference between the two, the difference between the maximum triaxial force appears to produce different ways to play the body limb segment to analyze the impact will kicking and high-kick body segments each limb elements, as a training Rugby players were landing considerations play basis. Methods: had participated in the Asian Games Rugby players as subjects. Foot to foot; at the waist, left knee, right knee, left ankle, right ankle of each adhesive wireless inertial sensors, sampling rate of 530Hz, wireless sensing transmission measurements, and made the move because of school-related parameters do statistical analysis. Result: a three-axis XYZ kicked away kicking ankle maximum average was 293.0, -348.6, -408.9m/s², high-kick ankle-axis XYZ maximum average was 274.2, -300.1, -332.1 m/s²,kicking and high-kick two kinds of methods to play right ankle triaxial force maximum average were 524.2,427.6m/s²; thus kicking acceleration was significantly greater than the average high high-kick. Three-axis XYZ kicking left ankle maximum average were -133.5, -108.4, -253.1m/s², high-kicking left ankle three-axis XYZ maximum average were -143.2, -76.6, -106.2 m/s², kicking and high-kick left ankle triaxial force two kinds of methods to play the maximum average were 306.0,194.0m/s²; thus kicking acceleration was significantly greater than the average high-kick. Conclusion: a foot when kicking the ball away to play instantly bounced the ball; high-kick is to get the ball bounced the ball at a higher point, showing the average acceleration support legs left ankle while waiting for the ball to rebound highs value data, significantly lower than the kicking left ankle. Each limb segment body from the triaxial force data also show that the impact players in drop kick, kicking, high-kick major factor, is focused on supporting the kicker left ankle and foot playing right ankle. The results of this analysis can be used as future output of each limb segment of players do play drop kick considerations basis. Keywords: kicking, high-kick, Accelerometer
