Physical activity is key to fighting obesity. To that extent, Medford has a good level of involvement in team sports. But for those who choose not to participate in a team sport, other options should be available, such as activities on the school grounds prior to and after the regular class day, where teachers or PE staff would be available to consult and answer questions on regulated physical fitness activities undertaken by the student.
Medford may also want to take advantage of grants available to fight childhood obesity; the Robert Wood Johnson Foundation has been offering grants for just such a purpose.
