The aim of this study was: i) to compute an energy balance of a slalom kayak competition by measuring the percentage contributions of the aerobic and anaerobic energy sources to total metabolic power (E(tot)); and ii) to compare these data with those obtained, on the same subjects, over a flat-water course covered at maximal speed in a comparable time. Experiments were performed on eight middle- to high-class slalom kayakers (24.8 +/- 8.1 years of age, 1.75 +/- 0.04 m of stature, and 69.8 +/- 4.7 kg of body mass) who completed the slalom race in 85.8 +/- 5.3 s and covered the flat water course in 88.1 +/- 7.7 s. E(tot) was calculated from measures of oxygen consumption and of blood lactate concentration: it was about 30 % larger during the flat water all-out test (1.72 +/- 0.18 kW) than during the slalom race (1.35 +/- 0.12 kW). However, in both cases, about 50 % of E(tot) derives from aerobic and about 50 % from anaerobic energy sources. These data suggest that, besides training for skill acquisition and for improving anaerobic power, some high intensity, cardiovascular conditioning should be inserted in the training programs of the athletes specialised in this sport.
i）通过测量有氧和无氧能量来源对总代谢功率（E(tot)）的贡献百分比，计算激流回旋皮划艇比赛的能量平衡；ii）将这些数据与在相同受试者身上，在可比时间内以最大速度完成的静水赛道上获得的数据进行比较。对八名中高级激流回旋皮划艇运动员（年龄24.8±8.1岁，身高1.75±0.04米，体重69.8±4.7千克）进行了实验，他们在85.8±5.3秒内完成了激流回旋比赛，并在88.1±7.7秒内完成了静水赛道。E(tot)通过测量耗氧量和血乳酸浓度来计算：在静水全力测试期间（1.72±0.18千瓦）比在激流回旋比赛期间（1.35±0.12千瓦）大约高30%。然而，在两种情况下，约50%的E(tot)来自有氧能量来源，约50%来自无氧能量来源。这些数据表明，除了进行技能训练和提高无氧功率训练外，还应在这项运动的专业运动员训练计划中加入一些高强度的心血管调节训练。
