Figure 2. Arterial O2 saturation (SpO2, panel A), vastus lateralis muscle (panel B) and pre-fontal cortex (panel C) tissue saturation index during repeated sprints in normoxia and hypoxia (FIO2: 0.138).

Figure 2

No interaction effect (condition x sprint) was found for any of the variables. § indicates a main effect of the condition: hypoxia reduced SpO2 (-13.7%, P = 0.001) and cerebral TSI (-17.8%, P = 0.003), but not muscle TSI (-5.3%, P = 0.56).
