p-values of Linear Mixed-Effects Models analyses (significant values in bold)* significant within-group change from Pre to Post
anot normally distributed and log transformed for the analyses. For easier interpretation, non-transformed data means were reported for all variables. RPE = rating of perceived exertion. RPE, heart rate and lactate values of the common highest intensity block, completed in the pre- as well as post-intervention test were reported (i.e., values at the same speed level in both tests).
