The Ultimate Frisbee Injury Study: The 2007 Ultimate Players Association College Championships

Abstract Background Reference frames ground spatial communication by mapping ambiguous language (for example, navigation: “to the left”) to properties of the speaker (using a Relative reference frame: “to my left”) or the world (Absolute reference frame: “to the north”). People’s preferences for reference frame vary depending on factors like their culture, the specific task in which they are engaged, and differences among individuals. Although most people are proficient with both reference frames, it is unknown whether preference for reference frames is stable within people or varies based on the specific spatial domain. These alternatives are difficult to adjudicate because navigation is one of few spatial domains that can be naturally solved using multiple reference frames. That is, while spatial navigation directions can be specified using Absolute or Relative reference frames (“go north” vs “go left”), other spatial domains predominantly use Relative reference frames. Here, we used two domains to test the stability of reference frame preference: one based on navigating a four-way intersection; and the other based on the sport of ultimate frisbee. We recruited 58 ultimate frisbee players to complete an online experiment. We measured reaction time and accuracy while participants solved spatial problems in each domain using verbal prompts containing either Relative or Absolute reference frames. Details of the task in both domains were kept as similar as possible while remaining ecologically plausible so that reference frame preference could emerge. Results We pre-registered a prediction that participants would be faster using their preferred reference frame type and that this advantage would correlate across domains; we did not find such a correlation. Instead, the data reveal that people use distinct reference frames in each domain. Conclusion This experiment reveals that spatial reference frame types are not stable and may be differentially suited to specific domains. This finding has broad implications for communicating spatial information by offering an important consideration for how spatial reference frames are used in communication: task constraints may affect reference frame choice as much as individual factors or culture.

O artigo trata de apresentar uma revisão literária sistemática, cujo objetivo central consistiu em mapear artigos publicados em periódicos nacionais, dedicados ao entendimento do Frisbee, no interstício temporal de 2009 a 2019. A pesquisa se assentou numa perspectiva qualiquantitativa. Para formular as categorias de análises, empregamos os pressupostos da homogeneidade interna, heterogeneidade externa, inclusividade e plausividade, somado ao princípio de análise inferencial, de maneira a possibilitar tanto à elaboração das categorias de análise quanto subsidiar ilações relativas às produções mapeadas. Após o emprego de todo o delineamento metodológico, constatou-se o total de 52 revistas, considerando todas as estratificações na subárea da Educação Física, com efeito, constatou-se três artigos atinentes ao Ultimate Frisbee. Os mesmos foram analisados no interior de três categorias analíticas, quais sejam: Participação; Sistematização Pedagógica e Gênero. Em linhas gerais, o que fica patente a luz de nossa investigação é a tendência de aumento no somatório das produções, a julgar o decênio cotejado, muito embora tenha havido uma quantidade equitativa nos últimos três anos.

The purpose of this investigation was to determine the rate of injury in eight intramural league sports at a small (< 3,000 students) private college in the southeastern United States. The number and types of injuries were tracked during the 2011–2012 and 2012–2013 academic years for eight intramural league sports: flag football, softball, floor hockey, volleyball, 3v3 basketball, ultimate frisbee, soccer, and 5v5 basketball. For the two academic years combined, the injury rate was 5.56 (95% confidence interval, or CI, = [4.67, 6.61]) per 100 participants; the major injury rate was 0.37 (95% CI = [0.19, 0.73]) per 100 participants. By assessing the rate of injury for intramural sports, intramural staff can strategically implement action plans to minimize risk and be better prepared to respond to injuries when they occur.

This study applies upper echelons theory associated with executive dismissal and power to examine the relationships of performance and four types of executive power— structural, prestige, expert, and governance concentration—with dismissal. Using the context of National Collegiate Athletic Association college basketball, in which coaches are completely responsible for strategies and human capital acquisition and retention, a curvilinear relationship between performance and dismissal is found. Significant relationships for prestige and expert power with dismissal are also found, but the “honeymoon period” is longer than prior studies of executive and coach dismissal have shown. Surprisingly, concentrated governance is found to be negatively associated with the likelihood of dismissal.

Context Injuries in professional ultimate Frisbee (ultimate) athletes have never been described. Objective To determine injury rates, profiles, and associated factors using the first injury-surveillance program for professional ultimate. Design Descriptive epidemiology study. Setting American Ultimate Disc League professional ultimate teams during the 2017 season. Patients or Other Participants Sixteen all-male teams. Main Outcome Measure(s) Injury incidence rates (IRs) were calculated as injuries per 1000 athlete-exposures (AEs). Incidence rate ratios were determined to compare IRs with 95% confidence intervals, which were used to calculate differences. Results We observed 299 injuries over 8963 AEs for a total IR of 33.36 per 1000 AEs. Most injuries affected the lower extremity (72%). The most common injuries were thigh-muscle strains (12.7%) and ankle-ligament sprains (11.4%). Running was the most frequent injury mechanism (32%). Twenty-nine percent of injuries involved collisions; however, the concussion rate was low (IR = 0.22 per 1000 AEs). Injuries were more likely to occur during competition and in the second half of games. An artificial turf playing surface did not affect overall injury rates (Mantel-Haenszel incidence rate ratio = 1.28; 95% confidence interval = 0.99, 1.67). Conclusions To our knowledge, this is the first epidemiologic study of professional ultimate injuries. Injury rates were comparable with those of similar collegiate- and professional-level sports.
