One of the National Football League's (NFL) Head, Neck and Spine Committee's principal goals is to create a 'best practice' protocol for concussion diagnosis and management for its players. The science related to concussion diagnosis and management continues to evolve, thus the protocol has evolved contemporaneously. The Fifth International Conference on Concussion in Sport was held in Berlin in 2016, and guidelines for sports concussion diagnosis and management were revised and refined. The NFL Head, Neck and Spine Committee has synthesised the most recent empirical evidence for sports concussion diagnosis and management including the Berlin consensus statement and tailored it to the game played in the NFL...

OBJECTIVES: To provide epidemiological data and related costs for sport-related injuries of five sporting codes (cricket, netball, rugby league, rugby union and football) in New Zealand for moderate-to-serious and serious injury claims. METHODS: A retrospective analytical review using detailed descriptive epidemiological data obtained from the Accident Compensation Corporation (ACC) for 2012-2016. RESULTS: Over the 5 years of study data, rugby union recorded the most moderate-to-serious injury entitlement claims (25 226) and costs (New Zealand dollars (NZD$)267 359 440 (£139 084 749)) resulting in the highest mean cost (NZD$10 484 (£5454)) per moderate-to-serious injury entitlement claim...

Although the epidemiology and risk factors for chondral injuries of the knee among prospective National Football League athletes have been reported, the effect of previously untreated chondral injuries on players' early National Football League career performance has been unclear to this point. Despite not requiring surgical treatment, players with these untreated injuries were drafted later, played and started fewer games, and exhibited lower fantasy scores-a surrogate marker for performance. Untreated chondral injuries of the knee can have potentially deleterious effects on the playing careers (and financial prospects) of professional American football players...

The 2017 Berlin Concussion in Sport Group Consensus Statement provides a global summary of best practice in concussion prevention, diagnosis and management, underpinned by systematic reviews and expert consensus. Due to their different settings and rules, individual sports need to adapt concussion guidelines according to their specific regulatory environment. At the same time, consistent application of the Berlin Consensus Statement's themes across sporting codes is likely to facilitate superior and uniform diagnosis and management, improve concussion education and highlight collaborative research opportunities...

Research has established that competing head to head against a rival boosts motivation and performance. The present research investigated whether rivalry can affect performance over time and in contests without rivals. We examined the long-term effects of rivalry through archival analyses of postseason performance in multiple high-stakes sports contexts: National Collegiate Athletic Association (NCAA) Division I Men's Basketball and the major U.S. professional sports leagues: National Basketball Association (NBA), National Football League (NFL), Major League Baseball (MLB), and National Hockey League (NHL)...

BACKGROUND: Acute ruptures of the ulnar collateral ligament (UCL) of the thumb are common injuries in sports. Surgical repair of complete tears has yielded excellent results in elite athletes. METHODS: National Football League (NFL) players who underwent thumb UCL surgery and matched controls were identified. Demographic and performance data were collected. Performance scores were calculated using a standardized scoring system. Return to sport (RTS) in the NFL was defined as playing in at least 1 NFL game after thumb UCL surgery...

The loss of players through injury is known to affect team performance in many sports; it is important therefore for professional teams to be able to quantify the likely injury-burden that will be encountered throughout a season. A kinetic model, based on the rates at which match and training injuries are sustained and resolved, a team's squad size and the 2017/18 season fixture schedule for teams competing in the English Premier League, is used to produce daily forecasts of injury-burden experienced by a typical team...

BACKGROUND: Anterior cruciate ligament (ACL) injuries are prevalent in contact sports that feature cutting and pivoting, such as American football. These injuries typically require surgical treatment, can result in significant missed time from competition, and may have deleterious long-term effects on an athlete's playing career and health. While the majority of ACL tears in other sports have been shown to occur from a noncontact mechanism, it stands to reason that a significant number of ACL tears in American football would occur after contact, given the nature of the sport...

Anterior ankle impingement is a frequent cause of pain and disability in athletes with impingement of soft-tissue or osseous structures along the anterior margin of the tibiotalar joint during dorsiflexion. In this study, we hypothesized that arthroscopic decompression of anterior ankle impingement would result in significant, reliable, and durable improvement in pain and range of motion (ROM), and would allow National Football League (NFL) players to return to their preoperative level of play. We reviewed 29 arthroscopic ankle débridements performed by a single surgeon...

Obesity has been previously noted as a major issue in the National Football League (NFL), where it has been shown that 97% of all players demonstrate a body mass index (BMI) of ≥25.0 with a reported obesity rate of 56% (BMI ≥30.0). However, BMI does not take into account body composition by mass, and may overestimate prevalence of obesity. The purposes of this study were to (1) determine the validity of BMI as a measure of body fat percentage and obesity in athletes at the NFL Combine, to define the obesity rate based on body fat percentage compared to BMI...
