Doing exercise can help people lose weight andhave a healthy life. Now,a new study has found good reason for doing exercise-it can help to improve student''s grades.
Dr. William and his team the University of Califoria studied doing exercise. the new study,students who often do sports are to get better grades.About 1,989 students took part in the study. The students came difrent grades. They made all the students part in the one-mile running test. The students who needed more than just one minute the run would lose one point in the later study test.
"If people want to be clever, they should have bodies." said Dr. William. "Parents should know the results this study. If their children want to do better in tests,they should plan enough time for study and exercise"
But they didn't find the reason. They will keep finding out why a healthy body plays important part in study grade.
