From: Assessment of exercise-induced stress via automated measurement of salivary cortisol concentrations and the testosterone-to-cortisol ratio: a preliminary study

Figure 4

Rates of change in the salivary testosterone and cortisol concentrations and the T/C ratio caused by each exercise in the two groups. The white box plots present the rate of changes in each parameter in the non-interval training (non-IT) group, and the gray box plots indicate those in the interval training (IT) group. The differences between the two groups were analyzed by using the Mann–Whitney U test. The differences between two time points of exercise among participants in the same group were analyzed by using the Wilcoxon signed-rank test.
