A new study says boosting students' levels of physical education improves their grades, HealthDay News reported.
瑞典科学家对200多名在校学生进行了跟踪试验。一部分学生被指定分到干预组，每周需要上5天体育课，此外还需要训练身体运动技巧，如身体协调性和平衡性的锻炼。剩下的同学被分到控制组，他们还和平常一样上体育课。
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.
研究结果表明，干预组有96%的学生取得了好成绩，可以顺利升初中，而控制组只有89%的学生。
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.
