[…] The statistical analysis was conducted in SPSS (version 20.0; IBM, Armonk, NY, USA). We performed a two-way analysis of variances with the fixed factors training (i.e., controls, athletes) and sex (i.e., male, female). Normality of the standardized residuals was tested using the Kolmogorov–Smirnov test with Lilliefors correction (Lilliefors, ) and Levene's test was applied to test homoscedasticity. If normality or homoscedasticity was violated, we separately tested differences between athletes and controls, and males and females respectively, using the Mann-Whitney-Wilcoxon test and Bonferroni adjustment (adjusted p-values, denominated padj, will be reported). The alpha level for all tests was set to 0.05. The effect size f for significant observations were calculated in G*Power (Version 3.1.6; HHU, Düsseldorf, Germany; Faul et al., ), based on either the partial eta squared or the group means and pooled standard deviation (for non-parametrically tested parameters). The subscript Training or Sex indicates if the effect size refers to differences between controls and athletes or males and females, respectively. Effect sizes of 0.1 ≤ f < 0.25 will be referred to as small, 0.25 ≤ f < 0.5 as medium and f ≥ 0.5 as large (Cohen, ). […]
