  1. n = 18 (except GET60+/−); values are expressed as mean ± SD; Significant results for OS_THb/O2Hb are presented in Fig. 4; SD_REC_ΔTHb/O2Hb/HHb represent the average standard deviation of the last 30 s of recovery; Time-to-peak values indicate the time from cessation of exercise to the highest value reached during the subsequent recovery period (asterisks indicate significant higher values compared to the other values, ** P < 0.01); End-exercise % \( \overset{.}{\mathrm{V}}{\mathrm{O}}_2 \) values are averaged values obtained from the final 10 s of each bout
