本研究目的：旨在透過基礎體能和專項體能的評量，探討單雙打羽球運動員速度及速度耐力表現的差異，並針對青少年羽球運動員未來專項體能訓練提出個人員建設性之建議，也為教練訂定訓練計畫和評量運動員訓練效果之參考。方法：以97年全中運高男羽球團體組總冠軍隊，十二位優秀男子青少年羽球國手為研究對象，六位單打運動員、六位雙打運動員。兩組分別進行以下五種測驗：（1）4分鐘『米字型』步法跑專項耐力測驗（2）4分鐘『米字型』步法跑後10秒鐘心跳率（3）100公尺速度測驗（4）400公尺無氧耐力測驗的（5）1600公尺有氧耐力測驗。測試所得各項體能測試指標，以獨立樣本t考驗進行單雙打兩組平均值差異檢定，考驗值α=0.5。結果：單雙打組別對4分鐘米字型跑平均值分別為114.83±2.99與108.17±2.71次；1600公尺平均值分別為320.00±8.12與324.83±5.56秒，有顯著性差異。而4分鐘米字型後10秒鐘之心跳率平均值分別為31.33±1.75與32.50±3.83次；100公尺平均值分別為13.48±0.28與13.70±0.18秒；400公尺平均值分別為61.33±2.81與62.83±1.72秒，沒有顯著差異。結論：單雙打羽球運動員體能表現在有氧速度耐力方面呈現顯著差異，單打運動員在速度耐力的表現方面普遍超越雙打運動員，但就專項速度而言，單雙打運動員並無顯著差異。建議依據單雙打運動員體能表現差異調整訓練模式，以符合單雙打運動員之需求。

This study was conducted to investigate the specific speed and speed endurance differences between elite single's and double's badminton players. Method: Twelve junior national elite male badminton players with mean (SD) age: 16.50 ± 1.0 years, mean (SD) height: 172.17 ± 2.9 cm, and mean (SD) weight 62.33 ± 2.0 kg from Neng Ren Commercial & Household Vocational High School were recruited and served as the subjects, who won the championship title in 2008 National High School Games. Subjects were divided into single's and double's groups and underwent the following tests: (1) A 4 - minutes footwork aerobic endurance test; (2) A 10 - seconds heart rate measured after 4 - minutes footwork; (3) l00m sprint test; (4) 400 m sprint anaerobic endurance test and, (5) 1600 m aerobic endurance running test. The independent sample t-test was utilized to exam the differences between groups, and the significant level was Q = .05. Results: It was found that the average performances for a 4-minute footwork in single's and double's players were 114.83 ± 2.99 times and 108.17 ± 2.7 times, respectively (p <.05); for the 1600m run were 320.00 ± 8.12 seconds and 324.83 ± 5.56 seconds, respectively (p <.05 ). The average heart rates for 10 - seconds measured after 4 - minutes footwork were 31.33 ± 1.75 beat/l0sec and 32.50 ± 3.83 beat/10sec, respectively (p >.05 ). The average performances for the l00m sprint were 13.48 ± 0.28 seconds and 13.70 ± 0.18 seconds, respectively (p >.05 ); for the 400m run were 61.33 ± 2.81 seconds and 62.83 ± 1.72 seconds, respectively (p >.05 ). Conclusion: There were significant differences in specific speed and speed endurance between single's and double's players. Since specificities of speed and speed endurance exit between elite junior single's and double's badminton players, it is suggested that the training should be adjusted to meet the specific demands of single's and double's badminton players.
