The Impact of Short-Term Mega Sporting Event Experiences on Student Learning

Short-term mega sporting events provide an opportunity for students to not only gain a memorable career experience but also enhance student skills and learning. However, very few (if any) researchers have explored students’ confidence related to key skills before and after such an event. Thus, the purpose of this study was to assess the effect of experiential learning at the National Football League’s 2023 Super Bowl LVII mega event on students’ learning outcomes. Students (N = 103) responded to an online survey distributed to assess their self-confidence across 18 learning-outcome skills covering problem solving, communication, sport-industry knowledge, and professional development. Each dependent-sample t test done to examine the students’ self-confidence with the individual learning outcome skills was significant (p < .001) and had meaningfully increased (Cohen’s d range: 0.47–0.97) from pre- to postevent. The results suggest that students can experience a notable increase in self-confidence when volunteering at a short-term mega sporting event. From a practical standpoint, the results provide sport management educators with strong evidence of the meaningful student learning related to problem solving, communication, sport-industry knowledge, and professional development that can occur with a single short-term mega-event experience.

Heterotopic Ossification and Platelet-Rich Plasma in Core Muscle Injuries: A Single-Institution Experience Over 6 Years

Background: A 2015 study of platelet-rich plasma (PRP) for groin injuries in National Football League (NFL) players alerted the authors to the possibility that PRP is associated with heterotopic ossification (HO). The current study of athletes seen between 2014 and 2019 provides a more comprehensive analysis of that observation. Purpose/Hypothesis: This report describes the early results of groin surgery for athletes who had experienced failed PRP therapy performed by different practitioners and with an assortment of PRP techniques. The primary goal of this cohort study was to determine short-term clinical outcomes after surgery of PRP-treated patients. It was hypothesized that previous PRP treatment would be associated with the presence of HO among patients with core muscle injuries (CMIs). Study Design: Cohort study; Level of evidence, 3. Methods: All athletes seen at 1 institution and identified at their first visit as having received PRP for a CMI were followed and compared with patients with a CMI who had not previously received PRP. Although in many cases HO was observed on clinical examination or imaging, HO was identified intraoperatively in all surgical cases and confirmed pathologically. Successful surgery was defined as return to play at previously high levels of performance or greater as determined by the athletes’ own assessments. All patients who had received PRP were followed for ≥2 years. Results: Among 3642 patients with a new CMI seen between 2014 and 2019, 68 (1.9%) patients developed HO within the core muscles and/or adjacent soft tissues. Of the 68 patients, 60 (88.2%) were men, and the mean age was 34.5 years. Of the 68 patients, 62 (91.2%) were athletes and 44 (64.7%) had been treated previously with PRP. HO was observed in 24 (0.7%) patients without previous PRP treatment. Three athletes who received PRP retired early from sports because of HO and scar issues. In total, 22 of 28 (78.6%) NFL players who received PRP developed HO, compared with 0 (0%) of 28 randomly selected, age-, position-, and injury-matched NFL players. After surgical repair, 3-month success rates were 67.9% and 96.4%, respectively, in the PRP and non-PRP groups (P = .006). By 6 months postoperatively, PRP-treated patients were back to similarly high success rates compared with the non-PRP cohort. Scar tissue issues played a prominent role in the relative delay in definitive success. Conclusion: The present, more comprehensive study confirms the previous preliminary analysis that treating CMIs with PRP may be associated with HO.

Field Surface Type and Season‐Ending Lower Extremity Injury in NFL Players

There is growing concern over the safety of artificial turf when it comes to the incidence of player injuries. The artificial surfaces can withstand more play, are cheaper to maintain, and are more predictable. However, there is concern that this beneficial durability comes at the expense of the forgiveness of the surface, leading to more injuries. In this study, we aim to compare the incidence of in‐game season‐ending lower extremity injuries on natural and artificial playing surfaces in the National Football League (NFL) during the 2020, 2021, and 2022 seasons. For this study, we used publicly available data to determine and classify the specific injury, where the injury occurred, field surface type, and duration of recovery. All data were collected, and significance was determined using two‐sample T‐tests. Only in‐game injuries were included in this study. Over the course of 2020, 2021, and 2022, there were 199 season‐ending lower‐extremity injuries. Of these, 79 occurred on natural turf (39.7%) and 120 on artificial turf (60.3%). Of the 891 games played in this three‐year period, 396 were played on natural turf (44.4%) and 495 were played on artificial turf (55.6%). Natural turf saw an injury rate of 0.199 per game, and artificial turf saw 0.242 injuries per game. We determined that there is no significant difference in rates of season‐ending lower‐extremity injury between artificial and natural turf. Any perceived difference in injury rates could possibly be attributed to the increased amount of play on artificial surfaces and anecdotal evidence related to high profile cases. While there is no significant difference in incidence, surfaces should continue to be monitored and regulated for traits such as hardness, and player preferences should be considered for qualities that are not quantifiable.

Tackling International Markets: Bicultural Brand Positioning of Sport Leagues in Foreign Countries

As sport league brands have increasingly extended their marketing activities into foreign countries, international brand positioning has become a relevant research topic. In this research, we introduce and examine the concept of bicultural brand positioning, an approach that combines a sport league’s connection to its home country with target-country associations. We integrate bicultural identity theory with the literature on brand benefits to propose two types of bicultural brand positioning: functional versus symbolic. Three experiments, using the National Football League and German satellite fans as the empirical context, provide evidence that bicultural brand positioning incorporating functional (vs. symbolic) benefits for the satellite fans increases bicultural brand image integration, defined as the perceived compatibility of combining the two country cultures, and has positive indirect effects on intentions to use the brand and positive word of mouth. These effects are driven by increased perceptions of cultural authenticity of the brand and brand convenience.

Leadership Theory and Ownership Succession in the National Football League: The Case of the Cincinnati Bengals

The fans in Cincinnati are in an uproar. They have just witnessed another disappointing football season, the 23rd since Mike Brown became the owner of the team. Mike Brown’s tenure has been marked by historically poor performance with eight and nine straight game losing streaks to begin the season on multiple occasions. To make matters worse, this was the same number of seasons that his father and Hall of Famer, Paul Brown, owned the team. Where Paul Brown’s tenure had been marked by record ascendence to the playoffs and two Super Bowl trips, his son’s tenure was notable primarily for seasonal failure. In the minds of the fans and press, the two eras of ownership could not be more starkly different. Both are now calling for wholesale changes to the leadership or the sale of the team. Students should examine these claims and both eras of ownership using transformational and charismatic leadership theories, Collins’ Genius with a Thousand Helpers leadership model, and family-owned business succession perspectives. Do the fans and press have a right to be angry and demand a change in leadership?

Predicting Future Quarterback Performance in the National Football League: Effective Use of Cognitive Assessments

Increasing Sport Fans’ Receptivity to Sustainability Messaging Through the Enhancement of Brand Authenticity

Brand authenticity is a crucial concept in determining a continuing relationship between a team and its fans. To better understand brand authenticity in the sport industry, this study explored how professional sport teams’ brand authenticity can be enhanced by its antecedents and what is the role of brand authenticity on fan loyalty, ultimately enhancing receptivity to environmental sustainability messaging. A total of 349 fans of the National Football League participated in an online survey. This research employed structural equation modeling to examine the relationships among the eight main constructs in the hypothesized research model. The results indicated that the five predictors positively influenced the team’s brand authenticity. Furthermore, enhanced brand authenticity impacted fan loyalty, while receptivity to environmental sustainability messaging was affected by fan loyalty and environmental sustainability attitude. The findings demonstrate how sport organizations can increase fans’ receptivity to environmental sustainability messaging through fans’ perceived brand authenticity and loyalty.

The Politics of Taking a Knee: Journalist Demographics and Media Analysis of the Colin Kaepernick Protest

During the 2016 National Football League season, Colin Kaepernick was the subject of intense media scrutiny as he protested racial injustice by taking a knee during the national anthem. Given the fact that the sports media is disproportionately dominated by White men, this study analyzed media framing of Kaepernick with particular consideration to the racial demographics of journalists producing media coverage. Our analysis indicates that positive articles (i.e., articles that praised Kaepernick) generally outnumbered negative articles (i.e., articles that criticized Kaepernick), but articles written by White men were significantly more likely to use negative frames, whereas authors of color more frequently framed Kaepernick in a positive way. Ultimately, we conceptualize media coverage of Kaepernick’s protest as a racial project that seeks to either reproduce or subvert meanings associated with race and racism.

Jones Fracture in the National Football League.

Background: Jones fracture, or proximal fifth metatarsal fracture, is a common injury in National Football League (NFL)-caliber athletes. Combine draft performance can greatly impact the long-term success of these athletes, and substantial emphasis has been placed on early return to play (RTP) and the minimization of post-operative complications after Jones fracture in these athletes. To date, no study has specifically described the treatment and outcomes of this injury specifically in NFL-caliber players, considering factors relevant to this unique population. Thus, the purpose of this review is to delve into Jones fracture in NFL-caliber athletes, evaluating the diagnostic, treatment, and RTP considerations. Methods: We searched Medline (PubMed), Embase (Elsevier), Scopus (Elsevier), and SPORTDiscus (EBSCOhost) for the concept of Jones fractures in the NFL. Using the PRISMA guidelines, a team of three reviewers conducted abstract screenings, full-text screenings, and the extraction of studies describing Jones fractures specifically in the NFL. Results: Of the 1911 studies identified, 6 primary retrospective studies met the inclusion and exclusion criteria. The heterogeneity of the outcome reporting precluded a meta-analysis; thus, a qualitative review of manuscripts describing Jones fracture was carried out. Classification, diagnosis, and treatment considerations, RTP statistics and outcomes, and complications were discussed. Amongst the primary studies, there were 285 Jones fractures, all athletes were able to RTP, and the average time to RTP ranged from 6 weeks to 27 weeks. For complications, with operative treatment, the refracture rate ranged from 4 to 12%, and incomplete healing ranged from 7 to 50%. RTP was 15 weeks for refractures. There were no patient-reported outcomes. Conclusions: The vast majority of Zone 2/3 Jones fractures are treated with IM screw fixation with or without adjunctive orthobiologics, such as bone marrow aspirate concentrate, in NFL-caliber athletes. The six major series investigating outcomes after the operative treatment of Jones fractures in NFL players reveal very positive findings overall with regard to RTP, reoperation, and career continuation.

Decreased Concussion Incidence Following the Implementation of the Targeting Rules: An Updated Epidemiology of National Football League Concussions From 2017 to 2022.

The incidence of concussions in football, and the ensuing media attention, has garnered scientific investigation, prompted technological advances in protective gear, and altered the rules of the game, including the National Football League's (NFL) "Targeting" rule, which began in 2018, but the impact of these changes is unclear. This study aims to describe the epidemiology of concussions that occurred in five NFL seasons from the 2017-2018 season through the 2021-2022 season and characterize positional differences in rate and games missed. There was a significant decrease (p = 0.02) in total concussions between the 2017-2018 season (102 concussions) and the remaining four seasons (average of 73.80 concussions per year), accounting for a 38% decrease. Offensive and defensive units had decreased concussion rates and average games missed per concussion. Defensive backs (10.46 per 1,000 athlete exposures (AEs)) and tight ends (10.69 per 1,000 AEs) had the highest concussion rates, and the defensive line had the highest average games missed per concussion at 3.97. The introduction of the "Targeting" rule and other rule changes in the NFL in 2018 correlated with a decrease in total concussions per year, total games missed due to concussion, and average games missed per concussion. Offense and defense experienced similar reductions in concussion incidence and severity. Overall, the updated epidemiology of NFL concussions suggests that the incidence of concussions has decreased; however, players continue to experience concussions that require them to miss multiple games.

Open Fractures in National Football League Athletes: Analyzing Performance and Return to Sport

INTRODUCTION Open fractures are potentially devastating injuries for the professional athlete. We sought to compare return to sports (RTS) and performance in National Football League (NFL) athletes sustaining open versus closed fractures. METHODS NFL athletes with surgically treated open and closed fractures of the forearm, tibial shaft, and ankle from 2009-2018 were identified through publicly available reports and records. Data including demographics, RTS, career duration, and the approximate value performance metric before and after injury were collected. Statistical analyses were performed comparing open to closed injuries. Continuous variables were compared using Mann-Whitney U or two sample t- tests while categorical variables were compared using Fisher’s exact test. RESULTS Ninety-five athletes met inclusion criteria (10 open and 85 closed fractures). Overall, 90% (n = 9) returned to sport after an open injury and 83.5% (n = 71) returned after closed injury with a median time missed of 48.9 (range 35.1 – 117.4) weeks and 43.0 (range 2.4 – 108.0) weeks, respectively. Athletes undergoing forearm surgery were able to return sooner, at around 20.8 weeks, and ankle fractures conferred the lowest return rate at 80% (n = 48). There were no significant differences in career duration and post-injury performance between open or closed fracture cohorts. CONCLUSIONS Although open fractures are relatively uncommon injuries seen in NFL athletes, our study suggests RTS for these players is high. Athletes undergoing surgical treatment for open fractures had similar RTS rates, performance metrics, and career durations compared to those with comparable closed fractures. This information can provide guidance for providers counseling elite athletes on postoperative expectations.

Managing Social Media Through Crisis: A Content Analysis of Instagram Posts Before and During the COVID-19 Pandemic

Abstract: Examining shift s in sport organizations’ social media content from before to during the pandemic-induced stoppage of play provides insight into digital branding during crises. Drawing on consumer-based brand equity and the context, content, and process framework, we examined adjustments made to brand image portrayal on Instagram and corresponding consumer engagement during the lockdown for two sport organizations at different seasonality stages. Results highlight how the National Basketball Association (NBA), facing the loss of their core product, utilized a need-based adjustment, while the National Football League (NFL) exhibited an opportunity-based adjustment. Analyses of consumer responses gauged the effectiveness of these two approaches, finding that the NFL was able to increase engagement, while the NBA suffered from declining engagement. Further investigation found that the NBA is still plagued by declined engagement since the pandemic, underscoring the importance of appropriate and effective digital branding during a crisis. While helping to fill the dearth of knowledge on how sport organizations operate under conditions outside of normalcy, this research improves our understanding of how social media content is managed during a crisis.

Escape Narratives and Regional Identity: A Case Study of the Story of Joe Burrow

This case study analyzes the news media’s framing of National Football League (NFL) quarterback Joe Burrow and his background during the 2019 football season, from the announcement of Burrow as a Heisman trophy finalist to the aftermath of his selection as the first overall pick in the 2020 NFL draft. With his heightened visibility on the field, Burrow’s background was increasingly of interest to football fans and sports journalists. It was not Burrow’s fairly “typical” family background as the child of a football coach in a nuclear family that received the most attention, but the Appalachian town of Athens, OH, where Burrow was a high school student, that became an important narrative. Emerging theme analysis suggests that sports journalists often extended idealized narratives to frame Burrow as an overcomer of a systemic cultural background with which he did not immediately identify. That narrative often utilized stereotypical representations of rural Appalachia as a place dominated by cultural poverty, highlighted representations of engrained hopelessness and lack of agency in the region, and reinforced problematic understandings of the nature of structural poverty and the ways it may be effectively challenged. The research addresses gaps in the literature about the college student-athlete in nuanced conversations about race and class in athlete-to-career narratives and notes the ways an athlete may call on such mediated tropes to extend a narrative for possible community or self-benefit.

Florbetapir amyloid PET in cognitively impaired former professional and college American football players

AbstractBackgroundRepetitive head impact (RHI) exposure from the routine play of American football increases the risk of later‐life cognitive impairment and dementia from the neurodegenerative disease, chronic traumatic encephalopathy (CTE). Although neuropathological studies of CTE have found comorbid neurodegenerative and other pathologies, neuritic Aβ plaques are infrequent, particularly in early stages. However, amyloid PET imaging has not been fully characterized in cognitively impaired former American football players.MethodIn this cross‐sectional, observational cohort study from the DIAGNOSE CTE Research Project, florbetapir PET mean cortical standard uptake value ratios (SUVR) and positivity (defined by average SUVR >1.10, indicative of moderate‐to‐frequent neuritic Aβ plaques), were analyzed in 119 former professional (PRO) National Football League players, 60 former college football players (COL), and 58 men unexposed (UE) to RHI who were cognitively asymptomatic. Former players were categorized into one of four diagnostic groups: cognitively normal (CN), subjective memory complaints (SMC), mild cognitive impairment (MCI), and dementia (DEM). All participants were 45‐74 yo. Multivariable linear and logistic regressions were conducted, with race, education, age, and APOE4 genotype included as covariates. A priori power calculations demonstrated adequate power to detect significant findingsResultNo differences between the three exposure groups in average florbetapir SUVR or proportion of elevated florbetapir uptake were found. Pairwise group comparisons resulted in no differences in average SUVR between PRO and COL (‐0.01, 95% CI [‐0.033, 0.025], p = 0.95), PRO and UE (0.02, 95% CI [‐0.010, 0.029], p = 0.41), and COL and UE (0.02, 95% CI [0.0004, 0.039], p = 0.36). Analysis of covariance resulted in no differences among diagnostic groups (F = 0.94, p = 0.43). Neither years of playing football nor measures of cognition and daily functioning showed significant associations with florbetapir SUVR.ConclusionFormer professional and college American football players with cognitive impairment and dementia did not have elevated florbetapir amyloid PET compared to a group of men without RHI exposure. Their rates of florbetapir positivity in the football players were lower than expected for a group of men this age. These findings suggest that cognitive impairment in former elite football players may not be due to Alzheimer’s disease pathology.

Black U.S. Military Affiliated Perspectives on Sport Media's Coverage of Racial Representation and Athlete Activism

Black U.S. military affiliated sport fans hold a unique place in society, as their multiple identities (i.e., racial and career) may possess conflicting elements. Militarism preaches nationalism, meritocracy, and bootstrapism, whereas Black sport activism questions if these “American” values extend to people of color. The current study interviewed Black military affiliated individuals ( N = 10) to understand their perceptions on nationalism and racism within the landscape of contemporary sport activism. The protests initiated by Colin Kaepernick of the National Football League, who took a knee during the pregame national anthem, was a focal point for discussion with the participants. Three main themes were identified in the interviews: (a) protectors of the first amendment, (b) the “right” and “wrong” way to protest, and (c) new racism and color blindness in sport. This study allows a group that is not often studied to voice their perceptions of nationalism and racism in the context of sport activism.

Does the Scouting Combine Influence a Player's Standing in the NFL Draft?

The annual scouting combine gives National Football League (NFL) teams an opportunity to assess over four days the skills of that year’s most promising college football players. The authors merge two data sets on over one thousand draft eligible football players spanning the ten-year period between 2014 and 2023 on their ultimate draft pick numbers and selected combine test results. Combine test results are converted to z-scores, that is, each participant’s number of standard deviations above or below the average performance in that year’s particular combine test. Wide receivers’ standing in the NFL’s draft correlates well with combine test results in the 40-yard dash. However, the authors find little-to-no relationship between combine test results and draft pick status over the last five years (let alone the last ten) for defensive backs, running backs, and defensive linemen who participated in, respectively, the vertical leap, broad jump, and bench press repetitions.

Managerial background, resource allocation, and team performance in the National Football League

ABSTRACT A manager’s prior experience may affect an organization’s resource allocation decisions and its performance. I examine this issue in the context of National Football League (NFL) franchises. I find that teams with coaches from an offensive background spend 5.5% points more of their salary cap space on offensive personnel, while a defensive background does not significantly affect the share of resources allocated to defensive personnel. While additional salary resources committed to offensive and defensive personnel do improve team performance in those respective areas, marginal improvements in offensive and defensive performance associated with greater spending are generally unaffected by the coach’s background, a finding suggesting that a coach’s background does not confer an informational advantage on certain types of personnel. I further find no evidence of significant differences in the effects that spending on offence and defence respectively have on team performance, suggesting efficiency within this labour market.

Epidemiologic trends in hand injuries in the National Football League from 2009-2010 to 2019-2020

ABSTRACT Objectives In American football, hand injuries have been shown to negatively impact performance. The purpose of this study is to characterize the prevalence and severity of hand injuries in National Football League (NFL) players. Methods A public online database was utilized to identify hand injuries in NFL players from 2009–2010 to 2019–2020. The primary outcome was to analyze the overall incidence of hand injuries (including wrist, metacarpus, finger, and thumb), injury type by each aforementioned anatomic location, and player position. Injury severity was evaluated based on percentage of injuries in which players returned to play (RTP), number of games missed before RTP, and the percentage of injuries resulting in the player being placed on injured reserve (IR). Results Of the 6,127 players included, 847 (13.8%) players sustained a hand injury, of which 24.8%, 34.3%, 17.9%, and 22.9% occurred at the wrist, metacarpus, finger, and thumb, respectively. Of the injured players, 97.4% returned to play following their injury, 14.8% were put on IR, and an average of 1.7 (SD 3.3) games were missed. Quarterbacks were the most likely to sustain hand injuries at all anatomic locations. Wrist injuries were associated with the lowest RTP rate (93.3%), the most players placed on injured reserve (28.6%), and the greatest number of games missed (mean 2.5, SD 4.2). Conclusion Hand injuries decreased in prevalence by 65.6% over the 11 NFL seasons evaluated. This trend coincides with the implementation of several safety rules that relate to components of play involving the hands. Quarterbacks experienced the greatest prevalence and severity for all hand injuries. Wrist injuries represent the anatomic location associated with the greatest severity. These findings may be able to inform tailored injury prevention practices by position, and advocate for the further adoption of safety rules to protect players from further injury.

Safety versus Compensation for Professional Athletes Who Face the Prospect of Career-Ending Injuries: An Economic Risk Analysis

The National Football League and National Hockey League have instituted several rule changes, equipment improvements and medical protocols in response to the frequency of serious career-ending injuries. These two professional leagues and others have litigated lawsuits by former players who have sought financial compensation. This paper constructs a simple economic model of a risk averse athlete who faces the uncertain prospect of a career-ending injury. Improving the athlete’s welfare can be accomplished by reducing the probability of a serious injury or providing increased compensation in the event of such an injury. The net marginal preference for safety is high in sports with moderate to high probabilities of serious injury. Compensation plans are favored in sports with moderate to low probabilities. Significant increases in player salaries have little effect on a players net marginal preference for safety. These results are robust to constant or decreasing absolute risk aversion.

General manager and head coach exits in the NBA and the NFL

PurposeThis article seeks to enhance the understanding as to why head coaches and general managers (GMs) in the National Basketball Association (NBA) and the National Football League (NFL) exit from their positions.Design/methodology/approachThree hypotheses were investigated using a series of quantitative and qualitative data from the past 30 years. The samples analyzed are comprised of 891 GM and coach annual observations for the NBA clubs and 949 GM and coach observations for the NFL clubs. Analyses include a logit analysis for coach exit/retention, a logit analysis for GM exit/retention and textual analysis via topic modeling via latent Dirichlet allocation.FindingsResults show a correlation between a coach exiting and a GM exiting simultaneously, thus amplifying the importance of these two roles in enhancing or destroying the success of a club and supporting the need for a deeper understanding of both roles, particularly the GM. The results further highlight cultural differences across clubs in terms of GM and coach turnover, a factor that often is heavily influenced by club ownership.Originality/valueThe results support the role of owners in exits, confirm the importance of winning in avoiding an exit, find a high level of interrelationship between GM and coach exits and show that past culture of firings influences future exit decisions.
