Article being edited:

In addition to the persistent effects on cognition that result from several months of daily exercise, acute exercise (i.e., a single bout of exercise) has been shown to transiently improve a number of cognitive functions. Reviews and meta-analyses of research on the effects of acute exercise on cognition in healthy young and middle-aged adults have concluded that information processing speed and a number of executive functions – including attention, working memory, problem solving, cognitive flexibility, verbal fluency, decision making, and inhibitory control – all improve for a period of up to 2 hours post-exercise. A systematic review of studies conducted on children also suggested that some of the exercise-induced improvements in executive function are apparent after single bouts of exercise, while other aspects (e.g., attentional control) only improve following consistent exercise on a regular basis. Other research has suggested immediate performative enhancements during exercise, such as exercise-concurrent improvements in processing speed during visual working memory tasks

Exercise impacts the body in multiple ways and increases the blood flow throughout the human body. Exercise plays a huge role in strengthening both your muscles and bones. Exercise stimulates brain activity and also activates the nervous system. The nervous system is one of the body's most important functions because of its ability to regulate every process in the body. Exercise benefits the central nervous system by increasing blood flow, reducing inflammation, and stimulating the release of growth factors (https://www.health.harvard.edu/blog/regular-exercise-changes-brain-improve-memory-thinking-skills-201404097110.

Article body

While pursuing aerobic exercise, the body is increasing its oxygen consumption. The body is consuming more oxygen due to the demand that is coming from the muscles. This uptake in oxygen stimulates increased blood flow throughout the entire body, including the brain. Increased blood supply and flow are beneficial to the human body because they supply the muscles with new blood while also carrying the muscle waste back to the kidneys https://lifesciences.byu.edu/how-exercise-affects-your-brain. Exercise works to reduce inflammation by altering the activity of the brain's immune cells, which then reduces the inflammation in the brain. This is very important because brain inflammation can lead to severe infections and cognitive decline. Brain inflammation can damage the structure and functions of the brain as well, reducing overall brain activity. Exercise stimulates growth factors in the brain by making new connections between cells and also develops brain plasticity. This development of the brain is extremely important because it improves both cognition and mood, affected in the prefrontal cortex of the brain. https://www.scientificamerican.com/article/how-exercise-affects-your-brain/. Mood is affected because during exercise because it triggers a release of both seratonin and dopamine. Both serotonin and dopamine are molecules that affect the ways that we feel, this includes temporary and long- lasting sensations.
