Abstract
本實驗在探討羽球兩種正拍網前挑球步法在移位過程中，下肢運動學及動力學參數之現象，希望藉此了解不同羽球步法之特性，提供教練選手訓練的參考。實驗參加者為8名大專組男子甲組羽球選手。使用8台Vicon紅外線攝影機 (300Hz) 擷取羽球正拍網前挑球兩種不同步法之運動學資料，以1塊Kistler測力板 (1500Hz) 同步蒐集受試者最後一步著地過程的動力學資料，並以Vicon Nexus1.8版軟體與Visual 3D軟體進行資料的計算與分析，以無母數統計威爾卡森符號等級考驗進行資料的統計與分析，統計水準設為α=.05。研究發現：一、三步的移位與擊球的時間明顯快於二步，但較快的速度可能會造成較大的地面反作用力。二、三步與二步在著地支撐期間，下肢各關節X軸向在著地前期關節會有離心收縮的現象發生，應於平時加強離心收縮的訓練。三、實施二步動作時，建議用較大的髖關節屈曲或膝關節屈曲進行著地來減少地面反作用力值，實施三步動作時，建議踝關節用較小的背屈來減少地面反作用力值。
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.
