Table 3 Statistical results for cardiac parameters of the time domain: heart rate (min\({-1}\))(HR), standard deviation of the NN intervall (SDNN) and root mean square of successive differences (RMSSD). They are given as patient-individual z-scores over all six experimental conditions. The results contain values from the \(2\times 3\) rm ANOVA for main effects and interactions: test statistics \(F(\text {df}_{f1}, \text {df}_{f2})\), significance level p, and effect size (Partial Eta Squared) \(\eta _p^2\). In case of significant main effects, post hoc (pairwise) t-tests are reported with the test-statistic \(T(\text {df}_{t})\), Holm-adjusted significance level \(p_{\text {adj}}\) and effect size as Cohen’s d.
