We investigated the relationship between maximal oxygen consumption (VO) and performance in vertical races (VRs). In total, 270 performances, from 26 VRs, and cardiopulmonary data of 64 highly-trained mountain runners (53 M, V O: 75.7±5.8 mL/min/kg; 11 F: 65.7±3.4 mL/min/kg), collected over a 11-year period (2012-2022), were analysed. The relationship between performance and VO was modelled separately for national (NVRs), international (IVRs), and VRs of current pole-unassisted and pole-assisted vertical kilometre (VK) records (RVRs). Three different (p<0.001) exponential models described the relationship between performance and VO in IVRs (R=0.96, p<0.001), NRs (R=0.91, p<0.001) and RVRs (R=0.97, p<0.001). Estimated VO requirements (with 95% CI) to win/set a record time in IVRs were 86.2(85.3-87.1)/89.4(88.2-90.5) and 74.0(73.6-74.4)/76.8(76.4-77.3) mL/min/kg, for males and females, respectively, 86.1(85.0-87.1)/90.4(89.0-91.8) and 74.8(74.2-75.3)/77.1(77.6-77.7) mL/min/kg in RVRs, decreasing to 83.7(82.5-84.9)/87.6(86.0-89.2) and 66.8(65.9-67.7)/70.7(70.1-71.4) mL/min/kg in NVRs. Our study also suggested a tendency towards a non-uniform variation in the metabolic demand of off-road running, likely attributable to the different features of the VRs (e.g., terrain, technical level, use of poles). These data provide mean VO requirements for mountain runners to win and establish new records in VRs and stimulate new research on the energy cost of off-road running.
我们研究了最大摄氧量（VO）与垂直竞速（VR）表现之间的关系。共有 270 名来自 26 场 VR 的表现和 64 名高山跑步者的心肺数据（53 名男性，VO：75.7±5.8 mL/min/kg；11 名女性，VO：65.7±3.4 mL/min/kg），这些数据是在 11 年期间（2012-2022 年）收集的。分别为国家（NVRs）、国际（IVRs）和当前杆辅助和杆辅助垂直公里（VRs）记录的 VR（RVRs）的表现和 VO 建立了三个不同的（p<0.001）指数模型。三个不同的（p<0.001）指数模型描述了 IVRs（R=0.96，p<0.001）、NRs（R=0.91，p<0.001）和 RVRs（R=0.97，p<0.001）中表现和 VO 之间的关系。在 IVRs 中赢得/设定记录时间所需的估计 VO 需求（95%CI）分别为男性 86.2（85.3-87.1）/89.4（88.2-90.5）和女性 74.0（73.6-74.4）/76.8（76.4-77.3）mL/min/kg，对于男性和女性，在 RVRs 中分别为 86.1（85.0-87.1）/90.4（89.0-91.8）和 74.8（74.2-75.3）/77.1（77.6-77.7）mL/min/kg，而在 NVRs 中则降至 83.7（82.5-84.9）/87.6（86.0-89.2）和 66.8（65.9-67.7）/70.7（70.1-71.4）mL/min/kg。我们的研究还表明，越野跑的代谢需求存在不均匀变化的趋势，这可能归因于 VR 的不同特征（例如，地形、技术水平、使用杆子）。这些数据为山地跑步者在 VR 中赢得和创造新纪录提供了平均 VO 需求，并激发了越野跑能量消耗的新研究。
