Q. I want to find some articles about the health benefits of children getting regular exercise.

The COM Library health/wellness and nursing databases are a good place to start this search.  To use them, follow the links below to each set of databases.  You can find articles on childhood exercise by searching for "physical fitness" AND children.  From there you can limit the search to full-text and specific types of sources (academic journals, magazines, etc.).  Make sure you have FULL TEXT selected in the search terms.

You could also try searching the databases for articles on childhood obesity, as many of them will discuss the benefits of physical exercise.
