Data analyses and statistics
After the range-data-plausibility control, outcomes were analysed using pre and post exercise values and absolute pre- to post-differences. Variables continuously monitored during the exercise bouts were processed in their absolute values. All analyses were performed using parametric or non-parametric testing based on the underlying assumptions (data structure, distribution of the variances and variance homogeneity). Between-group differences and pre- to post-changes were determined using omnibus and, in case of a significant omnibus main effect, follow-up post hoc testing. For the statistical calculations, SPSS 23 (SPSS Inc., Chicago, IL, USA) was used. For all statistical analyses, an alpha-error level of 5% was considered a relevant cut-off value for significance testing,
