摘要

目的：探討最大攝氧量（VO_2max）、身體組成、2×30秒溫蓋特測驗與2,000公尺室內划船運動表現的相關性，進而找出預估划船運動表現的最佳變項。方法：12名大學男性西式划船選手（年齡：20.2±1.0歲；身高：178.2±3.7cm；體重：75.9±7.7kg；VO_2max：59.4±3.5ml．kg^(-1)．min^(-1)）自願參與本實驗。在划船測功儀（Concept II）上進行每階3分鐘，每階增加35W的非連續性遞增負荷划船運動測驗時，監測血乳酸與攝氧量。在Monark腳踏車上進行間隔4分鐘（動態恢復）的2×30秒溫蓋特測驗，以測量平均功率、功率峰值與疲勞遞減率。身體組成是透過生物電阻法來分析體重與肌肉重。結果：2,000公尺划船的平均時間為417.0±6.7秒。多元迴歸分析顯示0-500公尺與1,000-1,500公尺的平均功率佔2,000公尺室內划船成績總變異中的98.3%。將絕對VO_2max、乳酸堆積起點（OBLA）所對應的功率、身高、體重、肌肉重、2×30秒溫蓋特測驗的平均功率與功率峰值代入順向多元迴歸分析時，可獲得以下預估2,000公尺划船表現的模式：Time 2,000（2,000公尺划船成績，秒）=656.98-0.257．（OBLA所對應的功率）-0.797．（身高）-1.444．（肌肉重）＋1.231．（體重）＋0.029．（第一次溫蓋特測驗的功率峰值）-0.090．（第一次溫蓋特測驗的平均功率）（r^2=0.911, SE=49.74,p<0.5）。結論：本研究結果顯示無氧動力是預測2,000公尺划船成績的重要變項，因此，西式划船選手應將訓練時間投注於加強無氧動力之改善。

This study investigated the relationships among maximal oxygen uptake (VO2 max), body composition, 2×30-s Wingate test variables and 2,000-m time-trial on a Concept Ⅱ rowing ergometer, and then established the best variables to predict the rowing performance. Twelve college male rowers (age, 20.2±1.0 yrs; height, 178.2±3.7 cm; weight, 75.9±7.7 kg; VO2 max, 59.4±3.5 ml．kg^(-1)•Min^(-1)) volunteered to participate in this study. Blood lactate and oxygen uptake were measured during a discontinuous graded exercise test on a rowing ergometer incremented by 35 W for each 3 min stage. The 2×30-s Wingate test, rest interval of 4 min active recovery was performed on a Monark bicycle ergometer to determine the mean power, peak power and fatigue percentage. Body composition was measured by the bio-impedance analysis to analyze the body weight and muscle mass. It was found that the average time of the 2,000-m time-trial rowing was 417.0±6.7 sec. The multiple-regression analysis indicated that 98.3% of the variation in 2,000-m indoor rowing performance time was predicted by the average powers of 0-500 m and 1,000-1,500 m. Submitting absolute VO2 max, power at the onset of blood lactate accumulation (OBLA), height, weight, muscle mass, mean and peak powers of the 2×30-s Wingate test to a forward multiple regression analysis produced the following model to predict 2,000-m rowing performance: Time 2,000 (time of 2,000 m rowing, sec)=656.98-0.257•(power at OBLA)-0.797•(height)-1.444•(muscle mass)+1.231•(body weight) +0.029•(peak power of the 1st 30-s Wingate test)-0.090•(mean power of the 1st 30-s Wingate test), (r^2=0.911, standard error=49.74, p＜.05). These results indicated that the anaerobic power was an important parameter to predict the 2,000-m indoor rowing performance. Thus, rowers should devote time to the improvement of anaerobic power.
