Modelling maximal power output and maximal oxygen uptake: Applications to cycling

The aim of this study was to assess which of the equations that estimate the PPO and the VO2max adapt best to the measurements made by reference systems in velodrome. Methods: Thirty-four triathletes and endurance cyclists of both sexes and heterogeneous performance level carried out three incremental tests, one in laboratory and two in velodrome. The VO2max was measured by means of an indirect calorimetry system in laboratory and the PPO was measured by means of the SRM training system in velodrome. The PPO and the VO2max of the field test were estimated by means of different equations. The agreement between estimated and reference values were studied with the Bland-Altman methodology. Results: The Olds et al. (1993, 1995) equations were the only ones that showed a good agreement with respect to the PPO references, particularly that of Olds et al. (1995). The McCole et al. (1990) equation was the only one that presented a good agreement with respect to the VO2max references. The VO2max values expressed in relative units showed the highest coefficient of determination with respect to the maximal aerobic speed. Conclusions: The Olds et al. (1995) and the McCole et al. (1990) equations are the best ones to estimate the PPO and the VO2max, respectively, in trained and elite endurance cyclists and triathletes in velodrome.
