The aim of this study was to determine the effect of cycle intensity on subsequent running performance and combined cycle-run (CR) performance. Seven triathletes undertook a cycling graded exercise test to exhaustion, an isolated 500-kJ cycle time trial (CTT) and an isolated 5-km running time trial. Then they performed a series of CR tests, at various cycle intensities, followed by an all-out, 5-km run. The CR tests were separated into four categories based on the percentage of the CTT at which the cycle was performed (CR 81-85%, CR 86-90%, CR 91-95%, and CR 96-100%). Running performance was slower during CR 96-100% compared to CR 81-85% and CR 86-90% (20:45 ± 1:19 vs. 19:56 ± 0:40 and 19:46 ± 0:49 min; P < 0.05), but not CR 91-95% (20:19 ± 1:08 min; P > 0.05). CR performance was maximised during CR 96-100% when compared to CR 81-85, CR 86-90 and CR 91-95% (56:37 ± 4:04 vs. 62:40 ± 5:30, 59:53 ± 4:41 and 58:29 ± 4:40 min; P < 0.05). The results suggest that combined cycle and run performance is maximised when the cycle is completed at the highest sustainable intensity.
本研究旨在确定循环强度对后续跑步表现和组合循环跑（CR）表现的影响。7 名铁人三项运动员进行了一项自行车递增负荷运动测试至力竭、一项单独的 500kJ 计时赛（CTT）和一项单独的 5km 跑步计时赛。然后，他们在不同的循环强度下进行了一系列的 CR 测试，随后进行了全力冲刺的 5km 跑步。根据完成的 CTT 的百分比，CR 测试分为四个类别（CR 81-85%、CR 86-90%、CR 91-95%和 CR 96-100%）。与 CR 81-85%和 CR 86-90%相比，CR 96-100%的跑步表现较慢（20:45±1:19 比 19:56±0:40 和 19:46±0:49 分钟；P<0.05），但与 CR 91-95%（20:19±1:08 分钟；P>0.05）相比没有差异。与 CR 81-85%、CR 86-90%和 CR 91-95%相比，CR 96-100%时的 CR 性能最高（56:37±4:04 比 62:40±5:30、59:53±4:41 和 58:29±4:40 分钟；P<0.05）。结果表明，当循环以最高可持续强度完成时，组合循环和跑步表现达到最大值。
