本發明是有關於一種姿勢評估方法，特別是指一種踢擊姿勢評估方法。 The present invention relates to a posture assessment method, in particular to a kick posture assessment method.

近年來隨著科技進步運動員的訓練也逐漸融合了創新科技，現有許多運動結合和虛擬實境(virtual reality,VR)模擬真實的場景讓運動員在虛擬世界中，透過選定關鍵的比賽情境反覆地模擬運動的操作，加速大腦與心智的訓練，快速累積賽場上的判斷能力。 In recent years, with the advancement of science and technology, the training of athletes has gradually integrated innovative technology.
