A Gamow bag
is an inflatable pressure bag large enough to accommodate a person inside. By inflating the bag with a foot pump, the effective altitude can be decreased by 1000 to as much as 3000 meters (3281 to 9743 feet). It is primarily used for treating severe cases of altitude sickness
Altitude sickness—also known as acute mountain sickness , altitude illness, hypobaropathy, or soroche—is a pathological effect of high altitude on humans, caused by acute exposure to low partial pressure of oxygen at high altitude...

This would produce more red blood cells to carry more oxygen to the muscles, increasing the athlete's abilities. However, this invention was not well-received despite glowing reviews. The equipment was deemed too bulky and susceptible to overheating.
Dr. Gamow persisted, and re-designed 'The Bubble' into a bag that could be used by high-altitude climbers
