Physical and mental health
The scores obtained for the physical health indicator in the SF-12 assessment were close to the normal distribution in the Kolmogorov–Smirnov test (The ITT analysis confirmed all above-described outcomes.In case of the mental health indicator in the SF-12 assessment the scores were not significantly different from the normal distribution (Here, similarly as in case of cortisol level, both groups differed significantly in the first assessment, thus we decided to add additional information about the relationship between the initial scores for mental health and the magnitude of change in both groups. We did similar analysis as previously for cortisol: correlation of the values obtained in the first assessment and the values of the difference between the two assessments (In the HIIT group the increase in mental health score was observed among 64.64% of participants, and in the EDU group among 37.50%. However, the difference between these two groups was statistically insignificant (The ITT analysis revealed that contrary to the above-described outcomes groups did not differ significantly in mental health during the Time 1 assessment (
