Abstract
ABSTRACTObjective: To obtain information on the incidence and nature of sports injuries at a Brazilian university.Method: Data from 396 student amateur athletes (61% male) playing 15 different sports during the 2013 season were retrospectively evaluated. Subjects completed the National Collegiate Athletic Association Injury Surveillance System questionnaire at the conclusion of the 2013 sports season. Injuries that resulted in at least one day of time lost were included. Exposure was defined as one student amateur athlete participating in one practice or game and is expressed as an athlete-exposure (A-E).Results: Injury rates were significantly greater in games (13.13 injuries per 1000 A-Es, 95% CI = 10.3-15) than in practices (4.47 injuries per 1000 A-Es, 95% CI = 3.9-5.1). The mechanisms that accounted for the most injuries in games and practices were player contact (52.9%) and non-contact (54.5%), respectively. Ankle ligament sprains were the most common injury (18.2% of all reported injuries). A relatively high incidence of anterior cruciate ligament injury was also observed (0.16 injuries per 1000 A-Es).Conclusion: Brazilian student amateur athletes are at great risk of sustaining non-contact injuries such as ankle sprains and anterior cruciate ligament injuries. Level III of Evidence, Study of non consecutive patients; without consistently applied reference ''gold'' standard.
Highlights
Since 1982, The American National Collegiate Athletic Association (NCAA) has supported an Injury Surveillance System (ISS), which collects injury and exposure data from 16 sports.[1]
Despite the amateur nature of Brazilian university sports, the game injury rate (13.13 injuries per 1000 A-Es, 95% IC = 10.3 – 15 or one injury every four games for a team of 20 participants) and the practice injury rate (4.47 injuries per 1000 A-Es, 95% IC = 3.9 - 5.1 or one injury every 10 practices for a team of 20 participants) of this population were very similar to the NCAAs game injury rate (13.8 injuries per 1000 A-Es, 95% CI = 13.7 - 13.9) and practice injury rate (4.0 injuries per 1000 A-Es, 95% CI = 3.9 - 4.0) (10), respectively
Given most injuries among NCAA athletes occur from player contact, preventative measures from ISS have largely focused on rules and policies that promote more secure contact between players, such as the no spearing and no clipping rules instituted in football.[10]
Summary
Since 1982, The American National Collegiate Athletic Association (NCAA) has supported an Injury Surveillance System (ISS), which collects injury and exposure data from 16 sports.[1] Over time, the data collected from ISS turned to be one of the most important source of knowledge in the sports medicine field. One of the most serious sports injuries, anterior cruciate ligament (ACL) tear, had its mechanism and gender distribution elucidated by ISS by a 5 year study with basketball and soccer players from NCAA as subjects.[2] In addition to orthopedics and sports medical areas, other ones were supported by data from ISS. Data regarding sports injuries have resulted in numerous successful injury prevention initiatives, including new models of football helmets to protect players from concussions[5] and equilibrium exercises to prevent ankle sprains in volleyball and basketball players.[6] This is in agreement with the 4 step injury prevention model proposed by van
