摘要

Aim. Maximal oxygen uptake (VO_(2max)) cycling protocols usually require expensive laboratory ergometers where the athlete is unaccustomed to the cycling position. Recently, we developed a VO_(2max) speed-ramped protocol with an indoor cycling simulator (Cateye Windtrainer WT) allowing cyclists to use their own bicycles during the VO_(2max) test. The aim of this study was to test the validity of the WT protocol by comparing it with a traditional (TD) resistance-ramped protocol using an electronically braked ergometer. In addition, the retest reliability of the WT protocol was also determined. Methods. Twenty experienced cyclists randomly completed 6 VO_(2max) protocols consisting of one familiarization trial and two tests on the WT and TD protocols.rnResults. There were minimal differences in maximal oxygen uptake values between protocols (WT 64.1 ± 7.1, TD 63.3 ± 7.4 mL/kg/min). The variability in the difference of the means between the two protocols was 0.8 mL/kg/min (95% confidence interval CI: -0.26-2.02), the coefficient of variation (CV) was 2.8% (95%CI: 2.2-4.2%) and the interclass correlation was r=0.94 (P < 0.01; 95%CI: 0.86-0.98). The intratest difference within the WT protocol was 1.5% (95%CI: -1.9-5%), CV=5.3% (95%CI: 4.1-8%) and the retest correlation was r=0.81 (P < 0.01; 95%CI: 0.57-0.92). Conclusion. The WT speed-ramped protocol is a valid and reliable method to assess VO_(2max).
