Fig. 2 Western blot data for (a) Cytochrome C (Cyt C), (b) Voltage-dependent anion channel (VDAC), (c) Heat Shock Protein 60 (HSP60), (d) Prohibitin (PHB1), (e) Cytochrome C Oxidase (COX-IV), (f) Succinate dehydrogenase (SDHA), (g,h) Representative western blots. * significant difference from baseline p < 0.05. Data shown as median ± upper/lower quantile and minimum and maximum. (CHO n = 12, PRO-CHO n = 12)

Fig. 3 (a) HAD and (b) CS enzyme (activity μmol g d.w.^− 1 min^− 1) at baseline and after six weeks of intervention in CHO (n = 12) and PRO-CHO (n = 12). ** significant difference from baseline p < 0.01. Data are presented as mean ± SEM

Fig. 4 (a) 6 K Time Trial (PRO-CHO; CHO) at baseline (n = 22), midway (n = 21) and post the intervention period (n = 21). Data is missing from 1 matched pair (n = 2), due to improper execution of the test. Furthermore, one subject did not complete the Midway and Posttest due to small injury not affecting the training. (b) VO_2max before (n = 24) and after intervention (n = 23). One subject is missing posttest due to lower back problems. Data are presented as mean ± SEM. *p < 0.05, **p < 0.01 ***p < 0.001 significant improvement from baseline
