Answer:
When we do high intensity Exercise our heart rate increases, supplying more blood flow to the brain. The increased heart rate also increases our breathing, making us breathe harder and faster. As a result more oxygen is supplied in our blood stream, more oxygen reaches our brain. This leads to neurogenesis, which is the production of neurons. Research has indicated that physical Exercise increases neurogenesis in the hippocampus, brain area important for learning and memory. Additionally, Exercise also influences the neurotrophies, it’s the family of protein that aids in neuron survival, development and function. This leads to greater brain plasticity and as a result better memory and learning. Regular physical activity lowers the risk of developing cognitive impairment, such as dementia, including Alzheimer’s disease. This improvement from the exercise is for people with normal and also impaired cognitive health, including people with ADHD, schizophrenia, multiple sclerosis, Parkinson’s disease, and stroke.
