| Summary: | 碩士 === 國立臺灣師範大學 === 體育學系 === 102 === The experiment to investigate two former badminton net to pick the ball forehand footwork during shifting, lower limb kinematics and kinetic parameters of the phenomenon, hoping to understand the characteristics of different badminton footwork, providing coaches and athletes training reference. Experimental participants were eight male college groups Group A badminton players. Use 8 Vicon infrared camera (300Hz) to capture two different kinematic data before badminton footwork forehand net pick the ball, with a Kistler force plates (1500Hz) subjects the final step in the synchronous gathering momentum to the process learning materials, and software version Vicon Nexus1.8 with Visual 3D software to calculate and analyze data, nonparametric statistics Will Carson signed-rank test for statistical and data analysis, statistical standards set α = .05. The study found: one, hitting a three-step shift with time significantly faster than the two-step, but a faster speed may cause greater ground reaction forces. Two, three-step and two-step in the ground support during lower limb joints in the ground early X axis eccentric contraction joints have occurred, should be strengthened eccentric training in peacetime. Third, the implementation of a two-step action, recommended greater hip flexion or knee flexion performed significantly reducing the value of the ground reaction force, the implementation of a three-step action, it is recommended to use a smaller ankle dorsiflexion to reduce the ground reaction force value.
