Abstract：
Background and Objectives: Studies analyzing lower extremity alignment (LEA) LEA among taekwondo subdisciplines athletes are lacking. This study compared LEA in the dominant and nondominant legs intaekwondo athletes. Materials and Methods: Twelve measurements of LEA were analyzed for 157 athletes (63 sparring, 50 demonstration, and 44 poomsae athletes) registered with the Korea Taekwondo Association. LEA was measured in the standing, supine, and prone positions using alignment application, a goniometer, a bubble inclinometer, a height gage, and a palpation meter. Results: The analysis revealed that the dominant leg of poomsae athletes showed greater genu valgum alignment than that of sparring athletes (p < 0.01), whereas the dominant leg of sparring athletes showed greater rearfoot varum alignment than that of demonstration athletes (p < 0.01). Furthermore, the nondominant leg of poomsae athletes showed greater genu valgum alignment than that of sparring and demonstration athletes (p < 0.01), whereas the nondominant leg of sparring athletes showed greater rearfoot varum alignment than that of demonstration athletes (p < 0.01). In addition, demonstration athletes had better forefoot varus alignment than poomsae athletes (p < 0.01). Conclusions: This study revealed that LEA characteristics vary among taekwondo athletes according to their subdiscipline. The results of this study would help in designing training programs tailored to each subdiscipline that would best address their LEA characteristics and help to prevent injuries.
摘要：
背景和目的：缺乏分析跆拳道亚学科运动员下肢对准（LEA）LEA的研究。这项研究比较了优势腿和非优势腿运动员的LEA。材料和方法：对157名运动员的12项LEA测量进行了分析(63项陪练，50演示,和44名poomsae运动员）在韩国跆拳道协会注册。LEA是在站立时测量的，仰卧,和使用对齐应用程序的俯卧位置，测角器,气泡测斜仪,一个高度计，和触诊仪.结果：分析显示，腿腿运动员的优势腿表现出比陪练运动员更大的genuvalgum排列（p<0.01）。而陪练运动员的优势腿显示出比示范运动员更大的后足内翻对齐（p<0.01）。此外，后腿运动员的非优势腿表现出比陪练和示范运动员更大的genuvalgum排列（p<0.01），而陪练运动员的非优势腿显示出比示范运动员更大的后足内翻对齐（p<0.01）。此外,示范运动员的前足内翻对准优于后足运动员（p<0.01）。结论：这项研究表明，跆拳道运动员的LEA特征因其子学科而异。这项研究的结果将有助于设计针对每个子学科的培训计划，以最好地解决其LEA特征并有助于预防伤害。
