跆拳道護具抗撞擊功能之比較分析

跆拳道是一項身體直接接觸的技擊運動，由兩位選手相互以足部的踢法組合成不同的攻擊型態來進行比賽，雖然競賽規則規定選手必須穿著護具（護肘及護脛）出賽，但依然常有撞擊傷害發生，輕者肌肉腫脹、瘀血，重者骨折送醫。爲有效降低撞擊所造成的傷害，研究者針對目前選手使用護具（一次發泡EVA及二次發泡EVA材質，厚度約1.5公分）及自行研發護具（粘彈性泡棉visco-elastic foam）進行撞擊實驗，以CE撞擊測試機進行撞擊實驗，將所得資料以相依樣本t檢定進行分析，進而瞭解並比較不同材質護具之抗撞擊功能。實驗分析結果顯示粘彈性泡棉抗撞擊功能顯著優於一次發泡EVA及二次發泡EVA（經撞擊後殘餘平均力量1.09公斤＜1.21公斤＜1.33公斤）。本研究結果可建議相關單位參考本研究之材料開發製作護具。

Taekwondo is a directly body contact martial art of attack and defense. Two athletes take part in a contest with their feet by using different attacking mode. According to the rules contesters need to wear protectors to secure their bodies. However, impact injury happened all the time. For minor injuries muscles appear swollen and congestion, but for serious injuries bone fracture will be occurred. In order to decrease the impact injure, the researchers devised a visco-elastic foaming protector to compare with currently been used protectors (first stage foaming EVA and secondary stage foaming EVA materials, about 1.5 cm thickness) and had an impact resistance test by using a CE impact tester. The data obtained were analyzed using a dependent-sample T test, and try to find out the capability of impact resistance on diverse materials of protectors. The result showed that the capability of impact resistance of visco-elastic foaming protector is better than first stage foaming protector and secondary stage foaming protector. (After impact, the average remnant strength are 1.09 kgs＜1.21 kgs＜1.33 kgs). This study, producing a visco-elastic foaming protector, could be a great resource for Taekwondo association while they select protectors.
