From: Hyperoxia Extends Time to Exhaustion During High-Intensity Intermittent Exercise: a Randomized, Crossover Study in Male Cyclists

Fig. 3

Mean arterial oxygen saturation (SpO2) levels were tested from 150 to 180 s during each high-intensity period. Hyperoxic (HO) conditions, FiO2 = 0.36, black; normoxic (NO) conditions, FiO2 = 0.21, white. Values were also averaged during the last 30 s of the fifth set of the tests (exhaustion). Values are means ± standard deviations (n = 8). *Significant difference vs. NO (P < 0.05). Significant difference vs. rest (P < 0.05)
