While albuterol is used to treat acute asthma it is also used widely in the sporting world. Those that use it claim to have "sports induced asthma". In the world of endurance, it is a benefit of sorts. It opens airways and speeds the heart rate. It is illegal to use according to the USOC and it's testing bodies. Gold Medals have been returned due to it.
This is another example of the extremes/shortcuts top athletes will try for an edge.
Albuterol may increase MVP if you suffer from it.
