"Enhancing performance
Therapeutic doses of psychostimulants, including amphetamine, improve performance on working memory tests both in normal functioning subjects and those with ADHD by increasing cortical network efficiency.[15] These stimulants increase arousal and, within the nucleus accumbens, improve task saliency.[15] Stimulants improve performance on difficult and boring tasks.[15]
Consequently, amphetamine is used by some college and high-school students as a study and test-taking aid.[45] Based upon studies of self-reported illicit stimulant use among college students, performance-enhancing use, as opposed to abuse as a recreational drug, is the primary reason that students use stimulants.[46] At doses much higher than those medically prescribed, stimulants can interfere with working memory and cognitive control.[15]
Amphetamine is also used by some athletes for its psychological and performance-enhancing effects.[14][28][47] In competitive sports, this form of use is prohibited by anti-doping regulations.[14] In healthy people at oral therapeutic doses, amphetamine has been shown to increase physical strength,[14][48] acceleration,[14][48] stamina,[14][49] and endurance,[14][49] while reducing reaction time.[14] Like methylphenidate and bupropion, amphetamine increases stamina and endurance in humans primarily through reuptake inhibition and effluxion of dopamine in the central nervous system.[48][49] Similar to cognition enhancement, very high amphetamine doses can induce side effects that impair athletic performance, such as rhabdomyolysis and hyperthermia.[13][24][48]"
