碩士 === 輔仁大學 === 體育學系碩士班 === 98 === Objective: This study, by means of kinematics analysis, biomechanics, motion analysis of curve balls, hoping to understand the curve ball kicking in soccer joint angle, angular velocity and angular acceleration of the shooting results. Methods: Three high-speed cameras to capture the arc of the ball shooting action use Kwon3D motion analysis software, kinematics analysis. Results: 1.Do not score goals and there is a significant difference, failed to score in the left shoulder with the goal of the joint angle range is 56.51 degrees and 149.44 degrees; left elbow joint angle range is 92.77 degrees and 142.46 respectively degree. 2.Goals and not scoring in the joint angular velocity is a significant difference, the change in the most obvious of which is the left shoulder and the left elbow, angular velocity, respectively, 21.23 rad / s and 17.58 rad / s; the left hip and significant differences right ankle joint, respectively, 27.23 rad / s and 36.73 rad / s. 3.Goals and not scoring in the joint angular acceleration are significant differences, of which the biggest difference for the left shoulder and left ankle joints, respectively, 31.44 rad / s and 404.33 rad / s, while the upper shoulder of the swing speed affect the lower limbs. 4. Left arm moment of inertia to help the human body and thus promote the formation of kinetic chain, and thus make the right hip, right knee and right ankle joint angular velocity and angular acceleration produced significant effects.
