 A recent research shows that physical activity (體育活動) may help students do better in their classes. The research comes because educators in some countries are reducing time for activities like P. E. class.

  Researchers go over the results of fourteen studies. Twelve were from the United States,one from Canada and one from South Africa. The studies appeared between 2009 and 2013. They included more than 55,000 children, aged six to eighteen.

Also,students who take part in organized sports learn rules and how to follow them. This could improve ：heir classroom behaviour and help them know what ：hey should do.
