Effect of hyperbaric oxygenation on maximal aerobic performance in a normobaric environment.
Eighteen female physical education students, randomly divided into three groups, inhaled 100% O2 for 60 minutes in a hyperbaric chamber. Pressure in the chamber amounted to 2.8 ATA. Three days before the hyperbaric oxygenation (HBO) all the students were subjected to a treadmill test. The first group was retested after 30 minutes, the second after 3 hours and the third 6 hours after the HBO. The first and the second groups of subjects achieved statistically significant maximal oxygen consumption after the HBO (14.4 and 10% respectively) and were capable of sustaining considerably higher exertion on treadmill (12.8%, namely 18.1%, both values were significant on the level of p less than 0.05). The ventilation efficiency parameters (VEO2 and R) did not differ with any of the three groups of subject during the exertion before and after the HBO, although after the HBO the exertion was considerably higher.
