The neurobiological effects of physical exercise involve possible interrelated effects on brain structure, brain function, and cognition.[1][2][3][4] Research in humans has demonstrated that consistent aerobic exercise (e.g., 30 minutes every day) may induce improvements in certain cognitive functions, neuroplasticity and behavioral plasticity; some of these long-term effects may include increased neuron growth, increased neurological activity (e.g., c-Fos and BDNF signaling), improved stress coping, enhanced cognitive control of behavior, improved declarative, spatial, and working memory, and structural and functional improvements in brain structures and pathways associated with cognitive control and memory.[5][6][7] The effects of exercise on cognition may affect academic performance in children and college students, improve adult productivity, preserve cognitive function in old age, preventing or treating certain neurological disorders, and improving overall quality of life.[8][9][10][11]

In healthy adults, aerobic exercise has been shown to induce transient effects on cognition after a single exercise session and persistent effects on cognition following consistent exercise over the course of several months.[1][7][12] People who regularly perform an aerobic exercise (e.g., running, jogging, brisk walking, swimming, and cycling) have greater scores on neuropsychological function and performance tests that measure certain cognitive functions, such as attentional control, inhibitory control, cognitive flexibility, working memory updating and capacity, declarative memory, spatial memory, and information processing speed.[5][7][12][13][14]

Aerobic exercise has both short and long term effects on mood and emotional states by promoting positive affect, inhibiting negative affect, and decreasing the biological response to acute psychological stress.[12] Aerobic exercise may affect both self-esteem and overall well-being (including sleep patterns) with consistent, long term participation.[15] Regular aerobic exercise may improve symptoms associated with central nervous system disorders and may be used as adjunct therapy for these disorders. There is some evidence of exercise treatment efficacy for major depressive disorder and attention deficit hyperactivity disorder.[9][16][17][18] The American Academy of Neurology's clinical practice guideline for mild cognitive impairment indicates that clinicians should recommend regular exercise (two times per week) to individuals who have been diagnosed with these conditions.[19]

Some preclinical evidence and emerging clinical evidence supports the use of exercise as an adjunct therapy for the treatment and prevention of drug addictions.[20][21][22][23]

Reviews of clinical evidence also support the use of exercise as an adjunct therapy for certain neurodegenerative disorders, particularly Alzheimer's disease and Parkinson's disease.[24][25] Regular exercise may be associated with a lower risk of developing neurodegenerative disorders.[26]
