据《每日健康新闻》报道，最新研究称，鼓励学生多上体育课有助于他们提高学习成绩。
Swedish researchers followed more than 200 schoolchildren. Some children were assigned to an intervention group that received physical education five days a week, plus extra training in motor-physical skills such as balance and coordination. The other children were assigned to a control group that received usual levels of physical education.

The study showed that 96 percent of students in the intervention group achieved grades that made them eligible to advance to upper-secondary school, compared with 89 percent of students in the control group.
