本研究主要目的，探討優秀跆拳道選手受傷率與危險因素變化情形。受試對象爲2008年奧運跆拳道國手選拔錦標賽的參賽選手，平均年齡18.1±2.3歲，比賽訓練年資6.4±1.3年，問卷150份，回收138份，回收率92%。統計方式以獨立t 檢定與因素分析，結果發現：一、男生受傷率顯著高於女生，受傷次數男生183 次，女生126次，共達309次，平均每人的受傷次數爲2.23次。男生以手指(9.8%)、膝部(8.7%)、腳跟(8.7%)爲最多，女生以腰部(48.0%)、膝部(7.1%)、踝關節(6.3%)爲最多。尤其以女生腰部受傷率最高，男生手指第二、膝部第三。二、受傷情形方面，挫、骨折，在受傷273次數當中以210次居最，佔總發生率的76.9%。三、男生37 % 比賽中受傷率最高，女生在訓練與比賽中受傷率最高(38%)。四、治療情形，男生以中醫爲主(46%)，國術館(26%)；女生以中醫爲主(50%)，國術館(21%)。五、男生選手在環境（噪音、空調溫度、溫差、光線）與其他（選手教練、對手、觀眾等因素），顯著低於女生。男生在軟體部分（系統、賽程安排、規則）顯著高於女生(t=2.82, p<.05)。跆拳道比賽受傷率高，判定分數爭議高，如何使爭議降低與避免運動傷害，是一個重要的課題。

The study was investigate to tae kwon do injure rate and risk factor in the competition. One Hundred thirty eight elite tae-kwon-do athletes from volunteered for the research. The average age of the fly weight group was 18.1±2.3 yr and average training period was 6.4±1.3 years. The data was analyzed by independent t-text and factor analysis. The result of study was followed: 1. Male was significant higher than female in injures. Male students are with the thigh (12%), finger (9.8%), waist (9.1%) and female student are with the waist (48.0%), wrist joint (4.3%), thumb (8.7%). 2. In injuring the situation: dampen, fracture, with 210 residence top, account for total 76.9% of incidence among injuring 273 number of times. 3. Male's injures 37% during competition phase and female 38% in training phase. 4. Male selected to be treated injures by Chinese medicine (46%) and traditional Chinese (26%). Female selected to be treated injures by Chinese medicine (50%) and traditional Chinese (21%). Male was significant higher than female in the risk factor of environment and coach. Male was significant higher than female in software part. It's important reference for coach and student-athlete to avoid injury and health management in training and competition.
