Aerobic power in prolonged exercise is related with the capability to continue exercise of an intensity corresponding to a fairly high percentage of V02 max besides the amount of V02 max itself. In the present study, the authors were led to the conclusion that the well-trained had excellent capability as regards physical resources and high adaptability to exercise and, accordingly, they showed more rapid acceleration of physiological functions than the untrained and could maintain high efficiency for oxygen supply through the whole course of exercise. Moreover, the increase in blood sugar content during exercise was marked in the trained, although exercise was considered to augment the uptake and consumption of sugar, but the increase in lactate content was comparatively small and that in serum FFA content was also rather low. Although the relative physiological work load seemed to be similar in both trained and untrained, the level of oxygen intake and the blood content during exercise were distinctly higher in the trained than in the untrained. These findings seemed to suggest the excellent aerobic power in the trained was helpful in augmentation of sugar oxidation.
长时间运动中的有氧能力不仅与最大摄氧量本身的数值有关，还与维持对应较高百分比最大摄氧量强度的运动能力相关。在本研究中，作者得出结论：训练有素者在身体资源方面具备出色能力，对运动具有高度适应性，因此，相较于未受过训练者，他们的生理功能加速更快，并且在整个运动过程中能够维持高效的氧气供应。此外，尽管运动被认为会增加糖的摄取和消耗，但训练有素者运动期间血糖含量的增加较为显著，而乳酸含量的增加相对较小，血清游离脂肪酸含量也相当低。尽管训练有素者和未受过训练者的相对生理工作负荷似乎相似，但训练有素者运动期间的摄氧量和血液含量水平明显高于未受过训练者。这些发现似乎表明，训练有素者出色的有氧能力有助于增强糖的氧化。
