Fit bodies may bring kids better test scores in school, a new study finds.

"Children's physical fitness is associated with their academic performance" said study author Lesley Cottrell, an associate professor of pediatrics at West Virginia University in Morgantown.

The researchers evaluated almost 1,200 students assessing their fitness in the fifth grade and then again in the seventh grade.  They tested them in 4 subjects - the seventh grade reading, math, science and social studies - using standardized tests.

The research hypothesized that those children who maintained fitness over the 2-year span would have the best test scores, and they were right.
