A joint study conducted by researchers at universities of Strathclyde and Dundee suggests that teenagers who exercise more often perform better in English, Math and Science examinations.
The researchers made use of data from the Children of the 90s study conducted between 1991 and 1992 and which tracked the long term health of around 14,000 children born in the UK. Around 5,000 children were selected for the new study with the researchers recording the duration and intensity of the children's daily physical activity levels when they were 11 years of age.
They found that on an average, the boys exercised for 29 minutes in a day while girls exercised for 18 minutes, well below the recommended limit of 60 minutes. The researchers then compared the amount of exercise done by the children when they were 13 and 16 years old and also recorded their academic performance. On calculating how the academic performance improved with increased minutes of exercise, the researchers found that an extra 17 minutes of exercise by boys improved their academic performance by a quarter of a grade while it was 12 minutes in girls.
