Athletic fatalities.

In 1985, we began studying athletic fatalities in Marion County, Indiana (city of Indianapolis, population 779,966) U.S.A. We previously reported the data for calendar year 1985. The reviewed cases include all sudden, unexpected, or traumatic deaths of conditioned, competitive athletes in Marion County. This follow-up is a review of all athletic fatalities in Marion County that occurred from January 1986 through July 1988. All deaths during or immediately after athletic activity were reviewed, whether or not the participant was a conditioned athlete. Natural disease, especially heart disease without prior diagnosis, continues to be the most prevalent modality of death.
