Implementation of concussion guidelines in community Australian Football and Rugby League– the experiences and challenges faced by coaches and sports trainers

Objectives

While guidelines outlining the appropriate management of sport-related concussion have been developed and adapted for use within community sport, it remains unknown how they are experienced by those responsible for implementing them.
Design

Longitudinal study.
Methods

111 coaches and sports trainers from community-level Australian Football and Rugby League teams completed pre- and post-season surveys assessing their attitudes towards using concussion guidelines. Participants also provided post-season feedback regarding their experiences in using the guidelines.
Results

71% of participants reported using the guidelines in the preceding season. Post-season attitude was related to pre-season attitude (p = 0.002), football code (p = 0.015), and team role (p = 0.045). An interaction between team role and guideline use (p = 0.012) was also found, with coaches who had used the guidelines, and sports trainers who had not, reporting more positive post-season attitudes towards using the concussion guidelines. Implementation challenges included disputing of decisions about return-to-play by players, parents, and coaches, and a perceived lack of time. Recommendations for improved guideline materials included using larger fonts and providing for witnessing of advice given to players.
Conclusions

This is the first study to examine the implementation of concussion guidelines in community sport. Training of coaches/sports trainers needs enhancement. In addition, new education should be developed for parents/players about the importance of the return-to-play advice given to them by those who follow these guidelines. Information provided by those who attempted to use the guidelines will assist the refinement of implementation and dissemination processes around concussion guidelines across sports.

Does playing a sports active video game improve young children's ball skill competence?

OBJECTIVES: Actual and perceived object control (commonly ball) skill proficiency is associated with higher physical activity in children and adolescents. Active video games (AVGs) encourage whole body movement to control/play the electronic gaming system and therefore provide an opportunity for screen time to become more active. The purpose of this study was to determine whether playing sports AVGs has a positive influence on young children's actual and perceived object control skills. DESIGN: Two group pre/post experimental design study. METHODS: Thirty-six children aged 6-10 years old from one school were randomly allocated to a control or intervention condition. The Test of Gross Motor Development-3 assessed object control skill. The Pictorial Scale of Perceived Competence for Young Children assessed perceived object control skill. The intervention consisted of 6×50min lunchtime AVG sessions on the Xbox Kinect. Two to three sport games were chosen for participants to play each session. General linear models with either perceived object control or actual object control skill as the outcome variables were conducted. Each base model adjusted for intervention status and pre-score of the respective outcome variable. Additional models adjusted for potential confounding variables (sex of child and game at home). RESULTS: No significant differences between the control and intervention groups were observed for both outcomes. CONCLUSIONS: This study found that playing the Xbox Kinect does not significantly influence children's perceived or actual object control skills, suggesting that the utility of the Xbox Kinect for developing perceived and actual object control skill competence is questionable.

Alcohol misuse interventions in the workplace: a systematic review of workplace and sports management alcohol interventions

Alcohol misuse has been linked to negative organizational outcomes, including reduced productivity and increased absenteeism. Additionally, media reports have focused on alcohol misuse within sporting organizations. Given the paucity of research evaluating alcohol misuse interventions in professional sporting organizations, two systematic literature searches were conducted. Review one examined alcohol interventions in the workplace, and Review two included sport as a search term. Resultant papers demonstrated four categories of workplace alcohol interventions; brief, web based, psychosocial, and random drug and alcohol testing. Brief interventions were prevalent, yielding largely non-significant results. Review two studies evaluated a community sporting intervention, which adopted an ecological, multi-level approach, yielding significant improvements in alcohol consumption, drink-driving, and club profitability. Brief interventions in workplaces were ineffective, and no brief interventions were found in elite sporting organizations. However, community sporting interventions showed promising results. Ongoing evaluation of alcohol interventions in professional sporting organizations are recommended.

Validity of a trunk-mounted accelerometer to measure physical collisions in contact sports

CONTEXT: Accelerometer peak impact accelerations are being used to measure player physical demands in contact sports. However, their accuracy to do so has not been ascertained. PURPOSE: To compare peak-impact-acceleration data from an accelerometer contained in a wearable tracking device with a 3-dimensional motion-analysis (MA) system during tackling and bumping. METHODS: Twenty-five semielite rugby athletes wore a tracking device containing a 100-Hz triaxial accelerometer (MinimaxX S4, Catapult Innovations, Australia). A single retroreflective marker was attached to the device, with its position recorded by a 12-camera MA system during 3 physical-collision tasks (tackle bag, bump pad, and tackle drill; N = 625). The accuracy, effect size, agreement, precision, and relative errors for each comparison were obtained as measures of accelerometer validity. RESULTS: Physical-collision peak impact accelerations recorded by the accelerometer overestimated (mean bias 0.60 g) those recorded by the MA system (P < .01). Filtering the raw data at a 20-Hz cutoff improved the accelerometer's relationship with MA data (mean bias 0.01 g; P > .05). When considering the data in 9 magnitude bands, the strongest relationship with the MA system was found in the 3.0-g or less band, and the precision of the accelerometer tended to reduce as the magnitude of impact acceleration increased. Of the 3 movements performed, the tackle-bag task displayed the greatest validity with MA. CONCLUSIONS: The findings indicate that the MinimaxX S4 accelerometer can accurately measure physical-collision peak impact accelerations when data are filtered at a 20-Hz cutoff frequency. As a result, accelerometers may be useful to measure physical collisions in contact sports.

Advertising the 2015 Cricket World Cup: representing multicultural female sports fans

Intersectional accounts of how women sports fans from diverse cultural backgrounds are represented remain largely unconsidered in fandom literature. This article examines an Australian advertisement for the 2015 Cricket World Cup, which features as its main protagonists female cricket fans supporting a variety of countries. It makes use of a transnational feminist cultural studies paradigm to frame a discussion of how commercial sports media narratives situate these fans as ‘‘ordinary.’’ In considering how the multicultural female sports fan is configured as ordinary in the Australian sporting context, I demonstrate the ways In which narratives of gender and nation are mobilized to situate multicultural women as marginal to both the Australian nation and cricket, despite the prominence given to ethnically diverse women in the advertisement. This manoeuvre, I argue, responds to the cultural and economic transformations of cricket globally, simultaneously denying and universalizing difference as a mechanism to assuage the anxieties generated by the decentering of Western power in international cricket.

Sports betting marketing during sporting events: a stadium and broadcast census of Australian Football League matches

OBJECTIVE: Using Australian Football League (AFL) matches as a case study, we investigated the frequency, length and content of marketing strategies for sports betting during two specific settings: 1) at stadiums during four live matches; and 2) during eight televised broadcasts of matches. METHODS: Census of sports betting marketing during Round 12 of the 2011 AFL premiership season. RESULTS: Per match, there was an average of 58.5 episodes (median 49.5, s.d 27.8) and 341.1 minutes (median 324.1 minutes and s.d 44.5) of sports betting marketing at stadiums, and 50.5 episodes (median 53.5, s.d 45.2) and 4.8 minutes (median 5.0 minutes, s.d 4.0) during televised broadcasts. A diverse range of marketing techniques were used to: a) embed sports betting within the game; b) align sports betting with fans' overall experience of the game; and c) encourage individuals to bet live during the game. There were very few visible or audible messages (such as responsible gambling or Gambler's Help messages) to counter-frame the overwhelmingly positive messages that individuals received about sports betting during the match. CONCLUSIONS AND IMPLICATIONS: This study raises important questions about the impacts of saturation, integrated and impulse gambling marketing strategies in sporting matches. Future research should explore: 1) how wagering industry marketing strategies may affect the attitudes and behaviours of community sub-groups (e.g. young male sports fans, and children); and 2) which public health and policy strategies, including regulation and harm minimisation messaging, will be effective in responding to wagering industry marketing strategies during sporting matches.

Accelerometer validity to measure and classify movement in team sports

 In team sports accelerometers are used to monitor the physical demands of athletic performance. Daniel's research showed that accelerometer accuracy can be improved through filtering. He also showed that the accelerometer can be used to automatically classify the type of movement performed. Further improving the understanding of team sports.
