本研究目的在探討輕艇激流標杆及輕艇靜水標杆運動表現和激流／靜水成績變化百分比之關聯性，以及兩種輕艇標杆賽乳酸反應的差異。實驗參與者為15位男性輕艇激流選手（年齡17.9±3.5歲，身高172.5±7.1公分，體重63.3±11.7公斤），訓練皆達4年以上。所有實驗參與者皆須進行輕艇靜水標杆及輕艇激流標杆兩項比賽，比賽間隔7天，比賽過程中記錄心跳率及比賽成績（秒），並於比賽前、後採集血液樣本以量測血乳酸濃度。研究結果顯示：輕艇靜水標杆與激流標杆之比賽成績呈現顯著相關，激流／靜水成績的變異係數和激流成績呈現顯著正相關，靜水標杆比賽的速度顯著快於激流標杆比賽的速度，惟兩種輕艇標杆賽之運動中最大心跳率及運動前、後血乳酸濃度皆無顯著差異。本研究結論：本研究結果推論激流成績較佳者，其於兩種標杆賽之成績表現的穩定性也較好；靜水標杆和激流標杆比賽過程中，選手的乳酸反應及相對運動強度類似。

This study aimed to investigate (1) the associations among performances of white-water slalom, flat-water slalom, and the coefficient of variation ratio of white water/flat-water slalom performance, (2) the comparison of the lactate responses between both types of slaloms. Fifteen elite canoeists (age 17.9±3.5 yrs, height 172.5±7.1cm, and weight 63.3±11.7kg) trained at least 4 years were voluntarily participated in this study. All participants performed two experimental trials: flat-water slalom race (FS) and white-water slalom race (WS). The two experimental trials were separated by a 7-day interval. Heart rate (HR) was measured throughout the trials, and capillary blood samples were collected before and after the race for lactate analysis. In the results, significant correlations were found between the performances of WS and FS trials, and also between WS performance and the coefficients of variation in WS/FS trials. Race speed in FS trial was significantly faster than that in WS trial. However, there were no significant differences in HR_(peak) and blood lactate concentrations before and after the race in both experimental trials. The main findings of this study suggest that the better performance in WS appeared to have better stabilities in both WS and FS, and both types of slalom races induced similar intensity and lactate responses.
