The '''neurobiological effects of physical exercise''' are numerous and involve a wide range of interrelated effects on brain structure, brain function, and [[cognition]].

There's a vast amount of neurobiological effects on brain structure, function, and cognition, caused by physical exercises. Numerous research has shown that that consistent exercise, can improve certain cognitive functions, healthy alterations in [[gene expression]] in the brain, and beneficial forms of [[neuroplasticity]] and [[Behavioral plasticity|behavioural plasticity]]. Exercise can also have some long-term effects, some of this are: increased neuron growth, increased neurobiological activity, improved stress coping, enhanced [[Cognitive control of behavior|cognitive control of behaviour]], improve declarative, spatial, and working memory, and structural and functional improvements in brain structures and pathways associated with cognitive control and memory. |

Article:
Sibley and Etnier (2003) performed a meta-analysis that looked at the relationship between physical activity and cognitive performance in children. They reported a beneficial relationship in the categories of perceptual skills, intelligence quotient, achievement, verbal tests, mathematic tests, developmental level/academic readiness and other, with the exception of memory, that was found to be unrelated to physical activity. The correlation was strongest for the age ranges of 4–7 and 11–13 years. On the other hand, Chaddock and colleagues (2011) found results that contrasted Sibley and Etnier's meta-analysis. In their study, the hypothesis was that lower-fit children would perform poorly in executive control of memory and have smaller hippocampal volumes compared to higher-fit children. Instead of physical activity being unrelated to memory in children between 4 and 18 years of age, it may be that preadolescents of higher fitness have larger hippocampal volumes, than preadolescents of lower fitness. According to a previous study done by Chaddock and colleagues (Chaddock et al. 2010), a larger hippocampal volume would result in better executive control of memory. They concluded that hippocampal volume was positively associated with performance on relational memory tasks. Their findings are the first to indicate that aerobic fitness may relate to the structure and function of the preadolescent human brain. In Best’s (2010) meta-analysis of the effect of activity on children’s executive function, there are two distinct experimental designs used to assess aerobic exercise on cognition. The first is chronic exercise, in which children are randomly assigned to a schedule of aerobic exercise over several weeks and later assessed at the end. The second is acute exercise, which examines the immediate changes in cognitive functioning after each session. The results of both suggest that aerobic exercise may briefly aid children’s executive function and also influence more lasting improvements to executive function. Other studies have suggested that exercise is unrelated to academic performance, perhaps due to the parameters used to determine exactly what academic achievement is. This area of study has been a focus for education boards that make decisions on whether physical education should be implemented in the school curriculum, how much time should be dedicated to physical education, and its impact on other academic subjects.
Another study found that sixth-graders who participated in vigorous physical activity at least three times a week had the highest scores compared to those who participated in moderate or no physical activity at all. The kids who participated in vigorous physical activity scored three points higher, on average, on their academic test, which consisted of math, science, English, and world studies.

Children who do aerobic exercises are shown to promote their Executive Function which is responsible for better cognition and behaviours. A research made by Sibley and Etnier in 2003, they performed a meta-analysis that looked at the relationship between physical activity and cognitive performance in children. They reported a beneficial relationship in the categories of perceptual skills, intelligence quotient, achievement, verbal tests, mathematic tests, developmental level/academic readiness and other, with the exception of memory, that was found to be unrelated to physical activity.

Brain Cancer:
A brain cancer or tumor occurs when a mass or an abnormal cell forms in the brain. This cancer can be benign (not cancerous), and malign (cancerous). There are different types of brain cancer, this are:
- Acoustic neuroma
- Astrocytoma
- Brain metastases
- Choroid plexus carcinoma
- Craniopharyngioma
- Embryonal tumors
- Ependymoma
- Glioblastoma
- Glioma
- Medulloblastoma
- Meningioma
- Oligodendroglioma
- Pediatric brain tumors
- Pineoblastoma
- Pituitary tumors
During the diagnosis of this cancer, patients are affected physically, cognitively and emotionally. Some research has shown that exercise can help reduce the side effects presented in diagnosis.
