The following list of professional organizations and resource groups represents the growing diversity in the field of sports medicine. The list also includes government agencies, sports-related groups, and academic centers that are active in tracking sports injuries.Several entries have been updated from the list THE PHYSICIAN AND SPORTSMEDICINE published in January 1992. We have also added five new entries. The list is divided into three sections: 45 sports medicine organizations, 26 groups and committees that generate sports medicine information, and 15 statistics-gathering groups. Some groups appear more than once; they have been cross-referenced in each instance. Entries in each of the three sections have been arranged alphabetically. When appropriate, we have given the names of directors and other officers.While THE PHYSICIAN AND SPORTSMEDICINE does not endorse any of the groups listed, we do encourage readers to contact the ones that interest them. We have included only the essential information about each group; more detailed descriptions can be obtained by calling or writing to the particular group you are interested in.Readers who would like their organization to be added to next year's list should contact THE PHYSICIAN AND SPORTSMEDICINE Organizations Project, 4530 W 77th St, Minneapolis, MN 55435.
