Introduction: Physiological parameters such as maximum oxygen uptake (VO2max), Absolute and Relative Peak Power Output (PPO, PPO·kg-1) and Maximal Fat Oxidation (MFO) are critical parameters in cycling performance and race success.
Objective: This study was designed to explore these physiological parameters and training characteristics of Under 23 (U23), Elite and Master 30 (M30) cyclists and its association with races’ performance.
Method: A cross-sectional study was conducted with thirty-four highly trained road cyclists (28.3 ± 7.4 years, 177.4 ± 6.0 cm, 68.4 ± 7.3 kg) who performed a VO2max test at the beginning of the pre-season period. Linear regressions were performed to examine the association between physiological parameters and weekly training hours. Analysis of Covariance (ANCOVA) was used to compare each physiological parameter across competitive categories while adjusting for weekly training hours as a covariate. Statistical significance was set at p < 0.05.
Results: A positive association was observed between training hours and VO2max, PPO and PPO·kg-1 (all p < 0.05). No association was found between training hours and MFO. Significant differences were found between categories in terms of VO2max, PPO and PPO·kg-1 (all p < 0.05) where Elite and U23 cyclists overperformed M30 cyclists, while no significant differences were found in MFO. No significant associations were observed between race performance and the physiological parameters mentioned.
Conclusion: Training volume in highly trained cyclists appears to be a key determinant of aerobic performance in VO2max, PPO and PPO·kg-1. Elite and U23 cyclists showed higher VO2max and PPO·kg-1 values than M30 cyclists, likely due to their training status and races demands.
