The aim of this study was to assess which of the equations that estimate peak power output and maximal oxygen uptake (VO2max) in the velodrome adapt best to the measurements made by reference systems. Thirty-four endurance cyclists and triathletes performed one incremental test in the laboratory and two tests in the velodrome. Maximal oxygen uptake and peak power output were measured with an indirect calorimetry system in the laboratory and with the SRM training system in the velodrome. The peak power output and VO2max of the field test were estimated by means of different equations. The agreement between the estimated and the reference values was assessed with the Bland-Altman method. The equation of Olds et al. (1995) showed the best agreement with respect to the peak power output reference values, and that of McCole et al. (1990) was the only equation to show good agreement with respect to the VO2max reference values. The VO2max values showed a higher coefficient of determination with respect to maximal aerobic speed when they were expressed in relative terms. In conclusion, the equations of Olds et al. (1995) and McCole et al. (1990) were best at estimating peak power output and VO2max in the velodrome, respectively.
本研究的目的是评估在自行车赛车场中估算峰值功率输出和最大摄氧量（VO₂max）的方程中，哪一个最适合参考系统的测量值。34名耐力自行车运动员和铁人三项运动员在实验室进行了一次递增测试，并在自行车赛车场进行了两次测试。在实验室中使用间接量热系统测量最大摄氧量和峰值功率输出，在自行车赛车场中使用SRM训练系统进行测量。通过不同的方程估算现场测试的峰值功率输出和VO₂max。使用Bland-Altman方法评估估算值与参考值之间的一致性。Olds等人（1995年）的方程在峰值功率输出参考值方面显示出最佳一致性，而McCole等人（1990年）的方程是唯一在VO₂max参考值方面显示出良好一致性的方程。当以相对值表示时，VO₂max值相对于最大有氧速度显示出更高的决定系数。总之，Olds等人（1995年）和McCole等人（1990年）的方程分别最适合估算自行车赛车场中的峰值功率输出和VO₂max。
