Fifty well-trained cyclists performed a simulated 16 km cycling TT test on two (Part A) or three (Part B) occasions.<em> </em>Mean power output (MPO), blood lactate and ratings of perceived exertion (RPE) were recorded following completion of 25, 50, 75, 90 and 100 % of the test. Overall MPO was analysed using intraclass correlations (r), systematic bias and ratio limits of agreement, coefficient of variation (CV) and t-tests. Pacing data, blood lactate and RPE were analysed using repeated measures ANOVA and Tukey tests for <em>post hoc</em> comparisons. Overall MPO in Part A (p = 0.11, d = 0.08, r = 0.95, CV = 3.04 ± 2.25 %) and in Part B (p = 0.72, d = 0.05, r = 0.87, CV = 2.93 ± 2.65 %) was not different between trials. MPO, blood lactate and RPE were not different between trials at any time point in Part A and B. The simulated cycling TT was shown to be reliable using a battery of statistical tests in well-trained cyclists, with and without a familiarisation session.</p> ER -
