Track and field is one of the most popular sports in the world. Despite the popularity of the sport, injuries are still a common occurrence. Hamstring strain injuries (HSIs) are reported to be highly prevalent in track and field, particularly during events involving high speed running. The Penn Relays Carnival, held annually by the University of Pennsylvania, is the oldest and largest track and field competition in the United States. Between 2002 to 2004, on average 16,158 athletes participated, making the Penn Relays Carnival an ideal event to observe the rates of HSIs in track and field. Therefore the purpose of this study was to determine the relative rates of HSIs across a wide number of events, age groups and genders in the Penn Relays Carnival between the years of 2002 and 2006.
