Perceptual and decision-making skills of Australian football umpires

This study evaluated a video-based testing protocol to assess perceptual and decision-making skill in Australian football. Whether umpires from two disparate levels of skill expertise could be discriminated on a sportspecific perceptual and decision making task was trialled. In addition, any task-specific differences between Australian football umpires’ and current players’ perception of the same game-play information were investigated. National league umpires, state league umpires, and national league players viewed video projected game-play sequences across three perceptual and decision-making tasks: 1) pattern recall, 2) play prediction and, 3) infringement identification (umpires only). Players performed better than both the umpire groups (p<0.05) in the pattern recall task. No significant differences were found across any groups on the play prediction task. The national league umpires made significantly (p<0.05) more correct decisions compared to the state league umpires on the infringement identification task. These results indicate that a video-based perceptual and decision-making task can discriminate between disparate umpire skill levels, and also between the task-specific perceptual skill sets of umpires and players in Australian football. There is potential for video-based assessment protocols to be utilised for the development of skill benchmarks and talent identification in Australian football and other ‘invasion-game’ sports.

Does Grit Influence Sport-Specific Engagement and Perceptual-Cognitive Expertise in Elite Youth Soccer?

We examined whether soccer players who score low and high on the personality trait grit can be differentiated based on their sport-specific engagement and perceptual-cognitive expertise. Findings revealed that grittier players accumulated significantly more time in sport-specific activities including competition, training, play, and indirect involvement. Moreover, there was a significant main effect for performance on the perceptual-cognitive skills tests across groups, with grittier players performing better than less gritty players on the assessments of decision making and situational probability. The findings are the first to demonstrate a potential link between grit, sport-specific engagement, and perceptual-cognitive expertise.

Assessment of decision-making performance and in-game physical exertion of Australian football umpires.

Abstract The aim of this study is to investigate the effects of in-game physical exertion on decision-making performance of Australian football umpires. Fifteen Australian football umpires (Mage = 36, s = 13.5 years; Mgames umpired = 235.2, s = 151.3) volunteered to participate in the study. During five competitive Australian football pre-season games, measures of in-game physical exertion (blood lactate levels, global positioning system [GPS]) and decision-making performance (video-based test) were obtained. There were no significant correlations between physical exertion in a particular quarter and decision-making performance in either the same quarter or any other quarter. Video-based decision-making performance was effected by time in game χ2(3) = 24.24, P = 0.001, with Quarter 4 performance significantly better than both Quarter 2 and Quarter 3. In-game physical exertion (blood lactate) significantly decreased over the course of the game χ2(3) = 11.58, P = 0.009. Results indicate no definable link between in-game physical exertion and decision-making performance. It is, however, presumed that decision-making performance may be affected by the time or context of the game. Future research is warranted to explore the relationship between physical exertion and decision-making performance to potentially inform Australian football umpire training programmes that replicate in-game physical and decision-making demands.

Development of a valid and reliable video-based decision-making test for Australian football umpires

OBJECTIVES To develop a valid and reliable video-based decision-making test to examine and monitor the decision-making performance of Australian football umpires. DESIGN Validation assessments with test re-test reliability. METHODS A video-based decision-making test was developed from a pool of 156 video-based decision-making situations. Australian football umpires (n=56) and players (n=45) participated in two separate phases of analysis. In phase one, players completed a test re-test reliability assessment with a 100 video-clips. Results indicated 24 clips were a reliable measure of decision-making performance. In phase two, umpires completed a test re-test protocol with 80 clips, 24 of which were the reliable clips identified by the player cohort in phase one. These 24 clips provided a measure of construct validity. Face and content validity were assessed by skill acquisition specialists, expert umpire coaches, and umpires. RESULTS From each of phase one and two of the reliability assessment, 24 clips were found to have a kappa value greater than 0.30, providing a total of 48 reliable video-clips. Construct validity was supported, with the umpire group performing significantly better than the player group on the 24 clips presented to both groups on each testing occasion. Face and content validity were also demonstrated. CONCLUSIONS This investigation demonstrated the ability prospectively to determine reliability and validity of the video-based decision-making test designed specifically for Australian football umpires. Establishing the validity and reliability of the video clips ensures future investigations can accurately and consistently measure the decision-making performance of Australian football umpires.

Talent identification and recruitment in youth soccer: Recruiter’s perceptions of the key attributes for player recruitment

Using the modified Delphi method, we aimed to understand the attributes youth coaches and recruiters perceive as important when identifying skilled youth performance at the entry level of representative soccer in Australia (i.e., Under 13 years). Furthermore, we also aimed to describe the current methods youth coaches and recruiters use to assess and identify these attributes in youth players. Australian regional youth technical directors and coaches (n = 20) completed a three stage process, including an initial interview and two subsequent questionnaires, whereby attributes and qualities associated with talent identification were rated and justified according to the importance for youth player performance and talent identification. Results indicate a hierarchy of attributes recruiters perceive as important for Under 13 soccer performance, including technical (i.e., first touch, striking the ball, one-versus-one ability, and technical ability under pressure), tactical (i.e., decision-making ability) and psychological attributes (i.e., coachability and positive attitude). In addition, the findings indicated attributes and qualities not emphasised within the talent identification process including, physiological, anthropometrical, sociological and several psychological attributes. It is suggested talent recruiters apply a holistic multidisciplinary approach to talent identification, with the current findings potentially providing initial evidence to suggest recruiters do consider numerous attributes when selecting and identifying youth players.

Talent identification and selection in elite youth football: An Australian context

Abstract We identified the perceptual–cognitive skills and player history variables that differentiate players selected or not selected into an elite youth football (i.e. soccer) programme in Australia. A sample of elite youth male football players (n = 127) completed an adapted participation history questionnaire and video-based assessments of perceptual–cognitive skills. Following data collection, 22 of these players were offered a full-time scholarship for enrolment at an elite player residential programme. Participants selected for the scholarship programme recorded superior performance on the combined perceptual–cognitive skills tests compared to the non-selected group. There were no significant between group differences on the player history variables. Stepwise discriminant function analysis identified four predictor variables that resulted in the best categorization of selected and non-selected players (i.e. recent match-play performance, region, number of other sports participated, combined perceptual–cognitive performance). The effectiveness of the discriminant function is reflected by 93.7% of players being correctly classified, with the four variables accounting for 57.6% of the variance. Our discriminating model for selection may provide a greater understanding of the factors that influence elite youth talent selection and identification.

The effects of physical exertion on decision-making performance of Australian football umpires.

ABSTRACT Decision-making is a key component of an umpire’s in-game performance, with each decision potentially having a direct impact on the result of the game. Additionally, umpires have to be physically fit to ensure they keep up with the gameplay. While research has identified the decision-making demands and running demands of umpires separately, few have explored the relationship between them. The aim of this investigation was to examine the relationship between physical exertion and decision-making performance of Australian football umpires at the sub-elite and junior levels. A total of 18 Australian football umpires (sub-elite, n = 10; junior n = 8) performed 10 × 300 m runs, with each repetition immediately followed by a video-based decision-making test, then 1 min of recovery. A Mann–Whitney U assessment indicated a significant difference between the sub-elite and junior level umpires for decision-making accuracy (U = 13.00, z = −2.43, P = 0.016, r = −0.5). However, there was no significant difference in response time (U = 28.00, z = −1.07, P = 0.315, r = −0.25). The sub-elite umpires completed the running efforts in significantly less time than the junior umpires (P < 0.05). Further, there was no significant correlation between decision-making performance and running times for either skill level (P > 0.05). This suggests decision-making performance may not be affected by physical exertion. Therefore, it may be suggested coaches of football umpires allocate more time to the decision-making development of their umpires instead of focusing largely on the physical fitness side, as is currently the trend.

Perfectionism and sport-specific engagement in elite youth soccer players

ABSTRACT It is acknowledged that the time invested in sport-specific activities contributes to higher levels of performance. However, there is limited understanding of the potential impact of personality traits, such as perfectionism, on engagement in sport-specific activities. In the current study, we examine whether elite youth soccer players who demonstrate higher and lower levels of perfectionistic strivings tendencies can be differentiated based on their sport-specific engagement. The Sport Multidimensional Perfectionism Scale 2 and an adapted Player History Questionnaire were completed by 419 elite youth male soccer players competing at the Australian age-related national youth championships (under 13, n = 133; under 14, n = 166; under 15, n = 120). A quartile split approach was used to separate higher (n = 100) and lower (n = 107) perfectionistic strivings groups. Findings revealed the higher perfectionistic strivings group accumulated more time in sport-specific activities, including coach-led practice, individual practice, peer-led play and indirect involvement in soccer when compared to individuals with lower perfectionistic strivings tendencies. Descriptive analysis indicates this equates to approximately 159 h a year (i.e. 17 h coach-led practice, 22 h individual practice, 60 h of peer-led play and 60 h of indirect involvement) more than the lower perfectionistic strivings group. In summary, the results suggest players with varying levels of perfectionistic strivings may be differentiated based on their engagement in soccer-specific activity in a sample of elite youth players in Australia, and suggests that perfectionistic strivings may have an adaptive influence on sport-specific engagement.

Observations of youth football training: How do coaches structure training sessions for player development?

ABSTRACT We used systematic observation tools to explore the structure (i.e., activity and inactivity) and sequencing (i.e., the types of activities used) of football coaching sessions in Australia following the implementation of a new National Curriculum. Youth soccer coaches (n = 34), coaching within the Skill Acquisition (U11–U13 n = 19) and Game Training (U14–U17 n = 15) phases of the Football Federation Australia National Curriculum participated. Participants were filmed during a regular coaching session, with systematic observation of the session undertaken to provide a detailed analysis of the practice activities and coach behaviours. Findings indicated a session comprised of Playing Form activities (40.9%), Training Form activities (22.3%), inactivity (31%), and transitions between activities (5.8%). Coaches prescribed more Training Form activities (e.g., individual (5.4%) and drills (15.1%)) early in the session and progressed to Playing Form activities (i.e., small-sided games (15.3%) then larger games (24.8%)) later in the session. Most inactivity reflected the players listening to the coach – either in a team huddle (9.9%) or frozen on the spot during an activity (16.5%). In addition, coaches generally spent over 3 min communicating to players prior to explaining and introducing an activity regardless of when in the session the activity was scheduled.

The pathway to the top: Key factors and influences in the development of Australian Olympic and World Championship Track and Field athletes:

Given the many benefits of international sporting success, understanding the development and long-term sustainability of an elite sporting career has become an important pursuit worldwide. Despite decades of research little is known about the development of elite senior Australian Track and Field athletes, therefore this study aimed to understand the major influences contributing to their development and success. A Track and Field Athlete Development questionnaire was used to collect data from 73 Olympic and World Championship level athletes. Analysis indicated athletes progressed to the elite level via six different pathways; however, the majority follows a linear pathway from junior to elite senior athlete. Further, results demonstrated the key influencing factors during development included later specialization, involvement in other sports during adolescence and strong social support. In addition, growing up in a major city and completing a University degree were also common features. Overall the study provides an insight into the development and success of Australian Track and Field athletes who competed at the Olympic Games or World Championships between 1956 and 2013.
