Similarly, the 5-HIAA content was the highest in the ER group, with highly significant differences compared to the control and the 4 h -exercised (EE) snails (Kruskal-Wallis test: H (3, N = 46) = 13.08, p = 0.0045, Figure 4 , the third group of bars, post hoc tests ER/Cn p = 0.029; ER/E p = 0.49; ER/EE p = 0.004; E/Cn p = 0.9; EE/Cn p = 0.85).
