There are several ways exercise can improve the brain. First exercise will increase blood flow to the brain, providing the brain with essential nutrients such as glucose and oxygen. Abnormal glucose tolerance can lead to brain impairments, and exercise helps regulate blood sugar levels.
In children, exercise has been shown to improve cognitive function, and improve motor skill development. Children who are active do better on standardized tests and have better grades. In adults, especially as we age, regular physical activity increases memory and slows the aging process of the brain. Studies show that very active people who engage regularly physical activities have much lower rates of memory loss, dementia, Alzheimer’s and do better on cognitive function tests over time.
