aOne-Way ANOVA compares the means between the various training groups and investigates the impact of the training on a given parameter; bTWO WAY ANOVA investigates the possible interaction between sex and training for a given parameter. All P-values were corrected for multiple comparisons. Main factors were sex and high vs intermediate training intensity. *comparison to controls is statistically significant, #comparison to high intensity SIT is statistically significant. Significance levels are: one symbol: P < 0.05; two symbols: P < 0.01; three symbols: P < 0.001.
