O2Peak (mL min−1 kg−1)
O2Peak: peak oxygen uptake; WLT: power at the lactate threshold; WPeak: peak power output; HRPeak: peak heart rate. Unpaired t-tests were used to assess differences between SIE and CE for age, body mass, height, HRPeak, 
O2Peak, WLT, WPeak at baseline, as well as total work, and 1-s max and mean exercise intensity during the biopsy trial. Changes in blood [La−] were analysed using a two-way ANOVA with repeated measures for time followed by Tukey’s honestly significant difference post-hoc test for pairwise comparisons. ‡P < 0.05 vs. CE at the same time point; *P < 0.05 vs. Pre. All values are mean ± SD. n = 9 for each type of exercise.
