  1. Values are expressed relative to cyclophilin, GAPDH and B2M housekeeping genes.
  2. Primary effects were analysed using 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. Pre. All values are mean×/÷SD. n = 9 for each type of exercise.
