The aim of this study was to identify if an inverse relationship exists between Gross Efficiency (GE) and V˙O2max in trained cyclists. In Experiment 1, 14 trained cyclist's GE and V˙O2max were recorded at 5 different phases of a cycling 'self-coached' season using an incremental laboratory test. In Experiment 2, 29 trained cyclists undertook 12 weeks of training in one of 2 randomly allocated groups (A and B). Over the first 6 weeks Group A was prescribed specific high-intensity training sessions, whilst Group B were restricted in the amount of intensive work they could conduct. In the second 6-week period, both groups were allowed to conduct high intensity training. Results of both experiments in this study demonstrate training related increases in GE, but not V˙O2max. A significant inverse within-subject correlation was evident in experiment 1 between GE and V˙O2max across the training season (r=-0.32; P<0.05). In experiment 2, a significant inverse within-subject correlation was found between changes in GE and V˙O2max in Group A over the first 6 weeks of training (r=-0.78; P<0.01). Resultantly, a training related inverse relationship between GE and V˙O2max is evident in these groups of trained cyclists.
本研究旨在确定在训练有素的自行车运动员中，总效率（GE）与 V˙O2max 是否存在反比关系。在实验 1 中，14 名训练有素的自行车运动员在一项“自我训练”赛季的 5 个不同阶段进行了递增实验室测试，记录了他们的 GE 和 V˙O2max。在实验 2 中，29 名训练有素的自行车运动员被随机分配到 2 个组（A 和 B）中的一个进行 12 周的训练。在第 1 组中，A 组在前 6 周被规定进行特定的高强度训练课程，而 B 组则限制了他们可以进行的密集工作的数量。在第二 6 周期间，两组都被允许进行高强度训练。本研究的两项实验结果均表明，GE 随着训练而增加，但 V˙O2max 没有增加。在实验 1 中，整个训练季节，GE 和 V˙O2max 之间存在显著的负相关（r=-0.32；P<0.05）。在实验 2 中，在训练的前 6 周，A 组的 GE 和 V˙O2max 的变化之间发现了显著的负相关（r=-0.78；P<0.01）。因此，在这些训练有素的自行车运动员组中，GE 和 V˙O2max 之间存在明显的训练相关反比关系。
