Exercise and Cognition
Exercise and Cognition is the study of how physical activity affects thinking and brain power.
A bowl of thick soup is hard to stir when cold. Warm it up first, and the spoon moves fast and smooth. Physical activity works like heat on your brain. After moving your body, your thinking flows more quickly and clearly.
Explaining exercise and cognition by grade level
Moving your body can help your brain work better. When you run or play, your brain gets more blood. This can help you think and learn. Try a short run before a test. You may do better on it.

A quick workout before a test might boost your score. In one experiment, 10 boys and 10 girls take exams in four subjects: math, science, history, and geography. Each subject has two papers of equal difficulty. On the first day they take Paper A with no exercise. The next day, they do 30 minutes of light activity — jogging or walking — rest for 45 minutes, and then take Paper B. Scores improve after exercising. Boys averaged 64.5% without exercise and 71.5% with it. Girls went from 69.5% to 75%.
Physical activity can affect thinking and brain power in the short term, not just over long periods. Both groups start by studying 20 household objects on a table for 45 seconds, then writing down what they recall. One group plays dodgeball for 20 minutes. The other reads quietly. When both repeat the memory test with new objects, the scores reveal how exercise shapes recall.
