目的：本研究目的是比較大專甲組跆拳道選手睡眠品質佳時的運動表現與睡眠品質不佳時的運動表現是否有差異。方法：以21名大專甲組跆拳道選手為實驗對象，平均年齡在20±2歲。本研究採受試者組內重複測量方式，每位受試者皆須各經歷一次五天睡眠品質佳與睡眠品質不佳的睡眠監控，隨後回顧一週睡眠狀況填寫匹茲堡睡眠品質量表及運動表現檢測。所得資料，使用SPSS統計軟體以相依樣本t檢定分析進行資料處理，顯著水準為α=.05。結果：研究結果發現選手在睡眠品質佳時旋踢踢擊磅數優於睡眠品質不佳時，在睡眠品質佳時旋踢踢擊反應顯著優於睡眠品質不佳時，在睡眠品質佳時垂直跳顯著優於睡眠品質不佳時，而睡眠品質佳時的攻、反擊準確度與睡眠品質不佳時攻、反擊準確度未達顯著相關。
