Stronger, Faster, Smarter
By Mary Carmichael
The text “Stronger, Faster, Smarter” written by Mary Carmichael states that exercise is the key to develop a healthier and smarter brain. According to the text, studies show that exercise such as aerobic doesn’t only increase the size of the muscles via the increased blood flow, the same thing happens to the brain. More blood equals more oxygen, which helps maintain the brain cells nourished better. The same kind of exercise has also coaxed the human brain to produce new nerve cells and caused older nerve cells to form interconnected webs that make the brain run faster and more efficiently. All which results in a stronger, faster and smarter brain. These statements are fully held out by research in the field of neuroscience and kinesiology described in the text and also confirmed in the field of biochemistry. With the view of a biochemist the evidence lies on the molecular level. When exercising, our muscles contract and release and within this particular motion a protein called IGF-1 finds it way to the brain through the bloodstream. This protein informs the brain of the increased activity due to the exercise, which makes the brain crank up its production of different chemicals needed to keep the body working in a new and more stressed state. One of these chemicals is called brain derived neurotrophic factor or BDNF and is indispensable when we talk about growing a bigger, stronger, faster and smarter brain. In fact a book on this subject calls it “Miracle-Gro for the brain. It fuels almost all the activities that lead to higher thought”. With this piece of information we can conclude in a scientific way that an increase of body exercise results in a higher production of chemicals and molecules in the body, where BDNF is one of them. With an increase of BDNF, blood and also oxygen we can conclude that not only does the process of exercise lead to an increased memory and improved function due to an...
