BACKGROUND A number of epidemiologic and surveillance-based studies of sports injury provide statistics on, and sometimes discussion of, overuse injuries. However, there is no consensus on the definition of "overuse." Some studies consider "overuse" as a mechanism of injury while others use a diagnosis-based definition. OBJECTIVE The objective of this(More)
BACKGROUND Overuse injuries result from microtrauma due to repetitive loading combined with insufficient tissue recovery time and can result in both immediate and long-term time loss from sports. HYPOTHESIS Overuse injury rates and patterns differ across college and high school populations, sport, and sex. STUDY DESIGN Descriptive epidemiology study. (More)
BACKGROUND Research has found that injury rates in football are higher in competition than during practice. However, there is little research on the association between injury rates and type of football practices and how these specific rates compare with those in competitions. PURPOSE This study utilized data from the National Collegiate Athletic(More)
BACKGROUND Shoulder dislocations occur frequently in athletes across a variety of sports. This study provides an updated descriptive epidemiological analysis of shoulder dislocations among high school and college athletes and compares injury rates and patterns across these age groups. HYPOTHESIS There would be no difference in injury rates/patterns(More)
OBJECTIVE To examine how injury definition inclusiveness affects the rank order of injury rates in 27 high school (HS) sports. DESIGN The National Athletic Treatment, Injury and Outcomes Network (NATION) used certified athletic trainers (ATs) to collect injury and athlete-exposure (AE) data in practices and competitions for 27 HS sports during the(More)
BACKGROUND Ankle sprains are a common injury in collegiate sports. Few studies have examined the epidemiology of individual ligament injuries, specifically the lateral ligament complex (LLC) of the ankle. PURPOSE To describe the epidemiology, including the estimated yearly national incidence, of LLC sprains among National Collegiate Athletic Association(More)
CONTEXT   Research on non-time-loss (NTL) injuries, which result in less than 24 hours of restriction from participation, is limited. OBJECTIVE   To describe the epidemiology of NTL injuries among collegiate and high school student-athletes. DESIGN   Descriptive epidemiology study. SETTING   Aggregate injury and exposure data collected from a(More)
BACKGROUND Ankle sprains are among the most common injuries experienced by collegiate athletes. The type of ankle sprain is rarely differentiated in epidemiological studies. This differentiation is necessary, as each ankle sprain type has a unique injury mechanism and recovery period. High ankle sprains commonly result in long recovery periods. Thus, a(More)
BACKGROUND In Indiana, high school football coaches are required to complete a coaching education course with material related to concussion awareness, equipment fitting, heat emergency preparedness, and proper technique. Some high schools have also opted to implement a player safety coach (PSC). The PSC, an integral component of USA Football's Heads Up(More)
CONTEXT Injury rates compare the relative frequency of sport-related concussions across groups. However, they may not be intuitive to policy makers, parents, or coaches in understanding the likelihood of concussion. OBJECTIVE To describe 4 measures of incidence (athlete-based rate, athlete-based risk, team-based rate, and team-based risk) during the(More)
