A hyperbaric oxygenation (HBO) session was administered before the stress event (HBOP group) or afterwards (HBOA group). The three groups (control, HBOP, and HBOA) were each divided into three subgroups: basal (B), fasting (F), and prolonged exercise (E). Measurements each group were made before and immediately after the stress event (B, F, and E) and following a 24-h recovery period (B24, F24, and E24). Tissue samples were taken where the box is marked with an “x”.
