Background: Physiology and performance of uphill time-trials (TT) in professional road cycling have been previously described (Lucia A et al., 2004; Padilla S, Mujika I, Orbañanos J, & Angulo F, 2000; Padilla S, Mujika I, Santisteban J, Impellizzeri FM, & Goiriena JJ, 2008). Recent field-based uphill trials focused on power output due to its reliability and accuracy to assess aerobic and anaerobic performance (Bossi AH, Lima P, Perrout de Lima J, & Hopker J, 2016; Vogt et al., 2008; Vogt et al., 2007). However few studies have attempted to correlate the different physiological and performances variables in field conditions. Objective: To assess the relationships among power output, velocity, cadence and oxygen uptake (VO2) during an uphill time-trial frequently used in cycling competitions. Methods: Fourteen elite road cyclists (mean±SD: 25±6 years, 174±4.2 cm, 64.4±6.1 kg) completed a field-based uphill TT in a 9.2 km first category mountain pass with a 7.1% slope. Oxygen uptake, power output, velocity and cadence were measured throughout the test. Results: During the TT mean power output and velocity were: 302±7 W (4.2±0.1 W·kg-1) and 18.7±1.6 km/h, respectively. Mean VO2 was: 3941±110 ml·min-1 (61.6±2.0 ml·kg-1·min-1). Mean power output, both absolute and relative to body mass, were strongly correlated with mean velocity (r= 0.82, for both correlations) and maximum velocity (r=0.77 and r=0.75, respectively). Strong associations were also observed between peak power output and both mean and maximum velocity (r=0.78 and r=0.80, respectively). Regarding cadence, a moderate correlation was appreciated with mean power output relative to body mass (r =0.50), whilst non significant associations were found with velocity. Finally, a moderate correlation between oxygen uptake (ml·min-1·kg-1) and power output relative to body mass was observed (r=0.42), (p < 0.001 for all correlations) Conclusion: During an uphill TT, velocity rises as a consequence of increasing power output whilst cadence and oxygen uptake do not seem as decisive in order to achieve a competitive advantage. Practical Application: This data may provide coaches and cyclists, both elite and non professional, with information to adjust training prescription accordingly, allowing them to compare their performance to an elite model.
