[…] A minimum number 21 participants was determined by a-priori analyses in G*Power 3.1, with an effect size of 0.65 (calculated as a Cohen's d based on VO2peak values in a similar sample from Baumgart and Sandbakk, , an alpha level of 0.05 and a power of 0.80. Two of the 24 participants were not able to complete the 1-min and the 3-min test on the second day. In these two tests, the data from 22 participants were analyzed. Breath-by-breath respiratory data was interpolated at individually fitted sample frequencies, resampled at 1-s intervals and 10, 30, and 60-s averages were calculated in MATLAB 8.1.0. (R2016a; Mathworks Inc., Natick, MA) The single highest 30-s average value was then identified as VO2peak as recommended by Robergs et al. () and used in the further analyses. The highest 10 and 60-s averages were used to investigate if changes in averaging procedure affected the results. Moving 3-s averages were calculated for the HR data and the highest value defined as peak heart rate (HRpeak). The higher of the two blood lactate values was defined as peak blood lactate (BLapeak). Thirty seconds averages were calculated for the PO data and the highest value defined as peak power output (POpeak).Data are presented as mean ± SD unless specified differently and an α level of 0.05 was employed to indicate statistical significance. All calculations and statistical tests were executed in Microsoft Excel (Version 2010, Microsoft Cooperation, The Microsoft Network, LLC, Richmond, USA) or in SPSS 22.0 (Software for Windows, SPSS Inc., Chicago, IL, USA).
