 Under the influence of drugs 
In healthy people at oral therapeutic doses, amphetamine has been shown to increase physical strength, acceleration, stamina, and endurance, while reducing reaction time.  Like methylphenidate and bupropion, amphetamine increases stamina and endurance in humans mainly through  the release of dopamine, and other central nervous system effects.
