羽球場地不同材質表面之避震差異比較

目的：評估三種不同運動表面羽球場的避震能力。三種場地分別為混凝土羽球場、PU羽球場和木質羽球場。方法：以攜帶式避震反彈測試儀進行撞擊測試，撞擊高度為3、4、5、6和7cm，撞擊器為5±0.1kg，經由固定於撞擊器上的加速規收集撞擊期間的負加速度峰值，取樣頻率為1,000Hz，每一高度取12次有效資料。統計方法採獨立樣本雙因子變異數分析。結果：1.隨著撞擊高度的增加，三種場地表面的最大負加速度峰值均會增加。2.相對於混凝土場地，PU場地可減少約4.8-11.32%的撞擊能量，木質場地可減少7.36-12.25%的撞擊能量。結論：PU場地與木質場地，具有接近的避震能力，但木質場地略優於PU場地；混凝土場地之避震能力比其他兩種場地相較之下約相差10%，建議在該類場地運動時應注意選擇羽球鞋，以避免運動傷害。

Purpose: This study was to evaluate the cushioning properties of different Badminton sport surfaces in different impact heights. Method: Three different surfaces were used to compare their shock adsorbing ability (SAA). The shock absorbing ability test instrument (SAATI) with a 5±0.1kg striker were place on the badminton sport surface to survey. According the procedure, SAATI was adjusted at 5 impact heights (3cm, 4cm, 5cm, 6cm and 7cm) to impact the shoe on the sport surface. At each condition, the impact was done 12 times repeatedly. Peak deceleration of the striker was measured with a an accelerometer attached to the striker during the impact. Independent Two-way ANOVA was used to compare peak deceleration of those sport surfaces. Results: 1. The higher impact height increased the peak deceleration. 2. PU surface reduced 4.8-11.32% impact energy compared with concrete surface; Wood surface reduced 7.36-12.25% impact energy compared with concrete surface. Conclusion: The SAA of wood surface and PU surface are similar but The SAA of wood surface is slightly better than The SAA of PU surface; We suggest that people should choose the shoe with good cushioning ability when playing the badminton in concrete surface.
