This study assessed the functional threshold power and the time to exhaustion estimated from the Allen & Coggan test and verify whether performance level has an influence on this parameter.
Cross-sectional study.
Twenty-minute test proposed by Allen & Coggan and cycling test to exhaustion were used to obtain the functional threshold power and a time to exhaustion. Cyclists were divided into performance groups based into 4 categories according to their VO.
The median (interquartile range) time to exhaustion at the functional threshold power was 35 (31-38) minutes for recreationally trained cyclists, 42 (38-51) for trained ones, 47 (41-56) for well-trained ones and 51 (44-59) for professional level cyclists. Time to exhaustion increased with cyclists' experience and performance level (p < 0.001).
The high time to exhaustion variability observed in this study suggests that functional threshold power and time to exhaustion should be assessed and reported independently for each subject. Also, cyclists' performance level and experience should be factored in when attempting to study the time to exhaustion, as better performing and more experienced cyclists consistently show longer times to exhaustion at the functional threshold power.
本研究评估了艾伦和科根测试中估计的功能阈功率和力竭时间，并验证运动表现水平是否对该参数有影响。
横断面研究。
使用艾伦和科根提出的 20 分钟测试和力竭骑行测试来获得功能阈功率和力竭时间。根据 VO，将自行车手分为 4 类进行表现分组。
在功能阈功率下，力竭时间的中位数（四分位距）为 35（31-38）分钟，休闲训练自行车手为 42（38-51）分钟，训练有素的自行车手为 47（41-56）分钟，训练有素的自行车手为 51（44-59）分钟，专业水平的自行车手为 51（44-59）分钟。力竭时间随自行车手的经验和表现水平的提高而增加（p<0.001）。
本研究中观察到的力竭时间变化较大，这表明对于每个个体，应分别评估和报告功能阈功率和力竭时间。此外，在尝试研究力竭时间时，应考虑自行车手的表现水平和经验，因为表现更好和经验更丰富的自行车手在功能阈功率下始终显示更长的力竭时间。
