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，並且接受超過5年以上跆拳道對打專項訓練，每周至少接受訓練10小時以上。本研究採受試者組內重複測量方式，測驗分成兩階段，(測驗一) 的部分將受試者分成兩組 (A組 「睡眠品質佳 」 B組 「睡眠品質不佳」 ) ，先進行五天的睡眠監控，並在五天後回顧一週睡眠狀況填寫匹茲堡睡眠品質量表 (PSQI) 及運動表現檢測，而 (測驗二) 的部分是將原先A組 「睡眠品質佳」 和B組 「睡眠品質不佳」 的組別對調，同樣進行五天的睡眠監控，一樣在五天後回顧一週睡眠狀況填寫匹茲堡睡眠品質量表 (PSQI) 及運動表現檢測，兩次測驗間隔七天。本研究所得資料，均使用SPSS統計軟體進行資料處理，顯著水準訂為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 (34.7±6.2 VS 31.7±6 lb，p=.001)；在睡眠品質佳時旋踢踢擊反應顯著優於睡眠品質不佳時 (0.55±0.1 VS 0.61±0 sec，p=.01)；在睡眠品質佳時垂直跳顯著優於睡眠品質不佳時 (42.7±9.5 VS 40.3±9.6 cm，p=.004)而在睡眠品質佳時的攻、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 (6.3±1 VS 6.7±1 fraction，p=.168) ( 7.8±1.3 VS 7.3±1.2 fraction，p=.197)；。結論：大專甲組跆拳道選手在睡眠品質佳時，旋踢踢擊磅數、旋踢踢擊反應、垂直跳等運動表現均顯著優於睡眠品質不佳時。而攻擊、反擊準確度則無顯著差異。
Objective: the current study was to investigate the influence of sleeping quality on Taekwondo performance of collegiate athletes. Methods: 21 college taekwondo athletes participated as experimental subjects, The average age was 20 ± 2 years, and all subjects had more than 5 years of training in Taekwondo sparring, with at least 10 hours of training per week. In this study, all subjects received repeated – measure. in two conditions including good sleeping quality condition and poor sleeping quality condition. Sleeping quality of both conditions was monitored by using Pittsburgh Sleep Quality Index (PSQI) Taekwondo performance was measured after both conditions. The two conditions were separated by 7 days. Result: The results indicated that with good sleeping quality, elite collegiate taekwondo athletes, performed significantly better in the spining kick hit power (34.7±6.2 VS 31.7±6 lb，p=.001). the spin kick strike reaction (0.55±0.1 VS 0.61±0 sec，p=.01). and vertical jump (42.7±9.5 VS 40.3±9.6 cm，p=.004).. No significant difference was found in the performance of attack and counterattack (6.3±1 VS 6.7±1 fraction，p=.168) ( 7.8±1.3 VS 7.3±1.2 fraction，p=.197). In conclusion: "Good sleeping quality" had better influence on spin kick hit pounds, spin kick strike reaction and vertical jump than "poor sleeping quality." However, there has no significant difference on accuracy of attack and counterattack.
