According to " ", the positive impact from aerobic activity, even small amounts of it. First of all, walking 20 minutes before a test raises children's grade. Secondly, the author describes there has no connection between muscular strength and I.Q. scores. However, aerobic exercise helps the brain grow factors and proteins. Last, the author comments everyone does more aerobic exercise, and get moving instead of sit and play 20 minutes video games. I strongly support the author's idea that walking 20 minutes before a test raises grades.
Just 20 minutes of walking before a test, increases test scores. First of all, usually a est takes more than one hour. Students need to sit in the room for more than one hour, it makes students disattracted, and makes students uncomfortable. However, if students just walked like 20 minutes before a test, it brings a lot of benefit to the test grade. In 20 minutes, students can relax and walk around, and take a deep fresh breath to be ready for the test. For example, a student is consider about test grade and very nervous sit in the test room, why not just walk around, take some fresh air, and relax body and mind. Then be confident in the test room.
