Rooms that can be found in the Rogla Sports Centre are equipped with special devices which modify the air pressure and, thus, the percentage of oxygen in the air. Through computer monitoring one can simulate various heights above sea level and, by that, also the concentration of oxygen. Training and living in these altitude rooms causes a rise in the number of erythrocytes (red blood cells) in the blood.

Consequently, this improves the delivery of oxygen to the muscles. The results of training and living in these rooms can be seen as early as after a couple of consecutive visits.
