The effectiveness of exercise for physical fitness is immense. Regular exercise increases physical performance. We also know more about exercise requirements to reduce the risk of various life-threatening diseases. As well as longitudinal studies, it has been shown that exercise also produces many positive changes in the brain.
Over the last few decades, studies of the changes in human attention, memory, and sensitivity of exercise have made it so convincing that the human brain works best after exercise. However, the exact cause could not be ascertained. But with the advancement of science and technology in recent times, scientists are slowly starting to get some ideas. This article attempts to highlight them.
Exercise makes the brain more active by increasing brain-wave
Generally, we have control of every movement, including movement, talking, behavior, emotion, and in the hands of neurons. The neurons in the brain communicate with each other using an electrical pulse. Brain-waves originate when different types of neurons vibrate together during communication.
Depending on the amount of brain wave vibrating every second, scientists divide the brain-wave into several ways. They are Delta, Theta, Alpha, Beta and Gamma Wave. When we are on auto-pilot; That is, we usually perform daily tasks such as brushing, sleeping, setting up a house, driving a car. Then a brain wave of low frequency is produced in our brain. On the other hand, when we are very careful about something, try to conclude. We use our brains to solve a problem. Then high-frequency brain waves like beta and gamma arise.
Richard Maddock is a psychologist at the University of California, He said that our brain becomes most active during exercise. Examination with an electroencephalogram showed that our brain observes high-frequency beta waves during exercise. That is, exercise can make your brain more alert to the situation around you.
Our brain has a large part of its back named visual cortex. It analyzes the visual information. This primary cortical region processes the information coming from the retina. It creates a sense of sight in us. The less important information in the environment or the scene at this time is likely to be visible in our brain.
Tom Bullock and Barry Griezbrecht are the professors of psychology and brain science at the University of California at Santa Barbara. They have long sought to find out what changes in the visual cortex of the brain during aerobic exercise. Their findings suggest that exercise is more about the environment around our brain to become more sensitive. At that time, the visual cortex becomes more interested in distinguishing more important visual information from certain important visual information.
Similar results have been found in various types of cognitive tests. For example, let’s say the ‘Flickr Fusion Threshold’ test is a remarkable one. Their flashes of light are seen shining incessantly at high-frequency. Various tests have shown that the temporary changes in burning after exercise make more sense. That is, the temporal changes in the frequency at which the flashes could not be detected before exercise, the brain could isolate the temporary changes at the frequency or even higher frequency after exercise.
The above findings indicate that exercise enhances your brain’s ability to see and understand clearly by making it more active.
Helps to create new neurotransmitters
Our lungs cannot provide enough oxygen to run at the same time as other aerobic exercises, including running. Our breathing becomes heavier and faster. At that time, our heart pumps to get enough oxygen into the body to deliver blood. As a result, the heart rate gradually increases. In this case our muscles demand more energy, and our brain swallows glucose and other carbohydrates.
In the past, there was no clear idea of what the brain does with such a large amount of fuel during exercise. However, in a study published in the Journal of Neuro-Science in Madok and his fellow researchers in 25, the brain uses a portion of the fuel to create new neurotransmitters.
It requires a type of chemical messenger for the transmission, modification and control of signals from one neuron to the other. The neurotransmitter is that messenger.
Maddock and his team called on their subject to exercise for a long time on stationary bicycles. They observed the creation of new neurotransmitters by measuring the neurotransmitter levels of cycling through MRI. At that time, they saw an increase in neurotransmitters such as glutamate and GABA-2. Madoc believes that the deficiencies in the chemical components needed for the brain to function properly, exercise helps to address those deficiencies.
At present, health centers recommend exercising to alleviate depression. Maddock and his team observed glutamate-produced neurotransmitters produced during exercise to increase in those areas of the brain, in areas where previously neurotransmitters were lower in depressed patients.
Creating a new connection between the nerves makes the brain more vibrant
Regular exercise creates new connections between neurons in the brain. A study by the University of Arizona showed that cross-country runners create new connections between neurons in the brain regions that are involved in memory, attention, multi-tasking, decision-making and processing of sensitive information. Usually, these areas are the most affected by the increase of age. Regular exercise creates new connections between the nerves. It also helps to preserve existing brain cells by producing a variety of growth factors.
On the other hand, neurogenesis requires nutrients or supplements to evolve emerging neural cells created in the hippocampus of the brain. Some studies have shown not only that, Barry Griezbracht, a professor of psychology and brain science at the University of California, said that aerobic exercise can also help to increase neurogenesis in the hippocampus. That exercise produces the necessary nutrients by enhancing the growth of blood vessels.
The last word
Charles Hillman, a professor of psychology at Northeastern University, believes that regular exercise may lead to small to medium-sized changes in the brain. It will help protect the brain’s health and enhance cognition. But do not think that exercise can increase IQ or even more.
But Tom Bullock and Barry Griezbrecht dream of a future where doctors will suggest exercise instead of medicine. About this, Griezbacht said, “Exercise is a potential antidote against age-related cognitive decline. Even exercise is the only simple way to get rid of aging problems or depressive disorders.”
