Higher VO₂max correlates with thicker cortex in the left superior temporal gyrus Furby, H.V., et al. (2020). Higher VO2max is associated with thicker cortex and lower grey matter blood flow in older adults.. Exercise increases several metabolic molecules in the hippocampus: AMPK (+24%↑), uMtCK (+60%↑), UCP2 (+50%↑) Gomez-Pinilla, F., Vaynman, S., & Ying, Z. (2008). Brain-derived neurotrophic factor functions as a metabotrophin to mediate the effects of exercise on cognition..

mental health benefits

Aerobic exercise is as effective as clomipraminei An antidepressant medication used to treat panic disorder and anxiety conditions. A controlled study found exercise equally effective without side effects. in reducing panic and agoraphobia symptoms [No authors listed]. (1998). Comparison of Aerobic Exercise, Clomipramine, and Placebo in the Treatment of Panic Disorder.. Regular physical activity prevents depression and anxiety Weinert, D., & Gubin, D. (2022). The Impact of Physical Activity on the Circadian System: Benefits for Health, Performance, and Wellbeing., promoting resilience and self-confidence.

Exercise attenuates cortisol levels by 50%↓ Motaghinejad, M., Asadi Ghaleni, M., & Motaghinejad, O. (2014). Preventive Effects of Forced Exercise against Alcohol-induced Physical Dependency and Reduction of Pain Perception Threshold., significantly reducing stress responses and improving mood regulation.

physical health improvements

Regular physical activity lowers the risk of coronary heart disease, type 2 diabetes, obesity, and certain cancers including breast and colon Weinert, D., & Gubin, D. (2022). The Impact of Physical Activity on the Circadian System: Benefits for Health, Performance, and Wellbeing.. Higher aerobic fitness correlates with longer life expectancy and reduced incidence of lifestyle diseases.

neurological benefits

Intensive exercise can restore circadian rhythms in individuals with disrupted biological clocks Weinert, D., & Gubin, D. (2022). The Impact of Physical Activity on the Circadian System: Benefits for Health, Performance, and Wellbeing., improving overall cognitive performance. Exercise regulates hippocampal neurogenesis Gomez-Pinilla, F., Vaynman, S., & Ying, Z. (2008). Brain-derived neurotrophic factor functions as a metabotrophin to mediate the effects of exercise on cognition., reducing learning deficits and improving memory. Circadian rhythmsi Circadian rhythms are 24-hour cycles that regulate physiological processes. Exercise helps synchronize these rhythms, improving sleep quality and cognitive function.

Six weeks of physical exercise accelerates glymphatic clearance, reducing amyloid-beta accumulation by 30%↓ Reddy, O. C., & van der Werf, Y. D. (2020). The Sleeping Brain: Harnessing the Power of the Glymphatic System through Lifestyle Choices., improving memory in neurodegenerative conditions.

pain management

Exercise increases endorphins, serotonin, and GABA [No authors listed]. (2021). Mechanism of exercise-induced analgesia: what we can learn from physically active animals., reducing pain perception. Regular physical activity enhances pain tolerance, shown by increased response times in pain threshold tests [No authors listed]. (2021). Mechanism of exercise-induced analgesia: what we can learn from physically active animals..

social & behavioral benefits

Voluntary exercise increases resilience to social defeat stress Greenwood, B. N., et al. (2011). Voluntary exercise increases resilience to social defeat stress., making individuals less anxious and more confident. Regular physical activity helps synchronize circadian rhythms with external time cues Weinert, D., & Gubin, D. (2022). The Impact of Physical Activity on the Circadian System: Benefits for Health, Performance, and Wellbeing., improving sleep quality and cognitive functions.

long-term rewards

Six weeks of voluntary running alters gene transcription in the brain's reward pathways Greenwood, B. N., Foley, T. E., Le, T. V., Strong, P. V., Loughridge, A. B., Day, H. E. W., & Fleshner, M. (2011). Long-term voluntary wheel running is rewarding and produces plasticity in the mesolimbic reward pathway., making exercise intrinsically rewarding and encouraging adherence. Individuals with higher fitness levels experience fewer language declines and better cognitive maintenance as they age Segaert, K., Lucas, S. J. E., Burley, C. V., Segaert, P., Milner, A. E., Ryan, M., & Wheeldon, L. (2018). Higher physical fitness levels are associated with less language decline in healthy ageing..
