- Description: In this review we identified sport-based perceptual-cognitive training literature to systematically evaluate current video-based methodologies and their resultant effectiveness to improve perceptual-cognitive performance (i.e., decision-making). A comprehensive literature search of electronic databases from 1994-2013 was conducted to identify relevant studies. We identified 139 articles, of which 25 met all the inclusion criteria. Study design and test measures of the 25 articles were assessed against a classification scale to rate methodological quality. The methodological quality of the 25 studies varied, with quasi-experimental the most common design. Additionally, studies varied in the skill level of participants and the amount of video-based information presented during the training. We conclude that videobased training programs can be used to enhance perceptual-cognitive performance and outline several recommendations for future video-based perceptual-cognitive training programs particularly with respect to the validity and reliability of the instruments used to measure perceptual-cognitive performance.

- Description: 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.

- Description: 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.

- Description: The principal purpose of this study was to identify those developmental factors most predictive of adult perceptual and decision-making skill. Qualitative data on developmental experiences and social support were collected from semi-structured interviews of 29 elite Australian Football League (AFL) players, 16 of whom were independently classified by a panel of coaches as expert decision-makers and 13 as less-skilled decision-makers. While high levels of parental support and a fierce desire to win, established from an early age, were evident for all players in the elite sample, the expert decision-makers were more likely to have bad (i) extensive experience of invasion games during their development, (ii) early experience of playing against adults or older children, (iii) playing experience in related sports (especially basketball), and (iv) their father as a coach at some stage during their junior years. The developmental characteristics observed for the expert decision-mak! ers extend quantitative findings on the practice hours of The same cohort (Berry et al., 2008) and indicate that observable differences in decision-making skills amongst adult players, even at an elite level, may be directly linked to each players particular developmental and practice experiences.

- Description: Abstract Objectives Internationally, children's movement competence levels are low. This study's aim was to evaluate the effectiveness of a 16 week gymnastics curriculum on stability, locomotive and object control skills and general body coordination. It was hypothesised that the gymnastics intervention group would demonstrate significant improvements beyond a PE comparison group. Design This study used a non-randomised control design. The intervention and comparison groups were drawn from three primary schools. The study followed the Transparent Reporting of Evaluations with Nonrandomized Designs (TREND) statement for reporting. Methods A total of 333 children (51% girls, 41% intervention) with a mean age of 8.1 years ( sd = 1.1) participated. Intervention children (16 weeks x 2 hrs of gymnastics) were compared to children who received (16 × 2 hrs) standard PE curriculum. Children's movement competence was assessed using the Test of Gross Motor Development–2, Stability Skills Assessment and the Körper-Koordinationstest für Kinder. Multilevel linear mixed models, accounting for variation at the class level and adjusted for age and sex, were used to assess intervention relative to comparison differences in all aspects of movement competence. Results Stability and object control skills showed a significant ( p < .05) intervention x time interaction effect. No difference was found in locomotor skills or general coordination. Conclusions Gymnastics is effective at developing stability skills and object control skills without hindering the development of locomotor skills or general coordination. Accelerated learning of stability skills may support the development of more complex movement skills.

- Description: Decision-making is fundamental to officiating in all sports. It is well established in contemporary research that decision-making skills underpin umpire expertise; however, there is little understanding of the cognitive processes that contribute to in-game decision-making. This research implemented an in-depth case study approach, using qualitative methods, to explore the in-game decision-making process of three Australian football umpires. Concurrent and retrospective verbalisation methods were used to obtain verbal reports of the cognitive processes associated with decision-making. Findings identified three salient themes related to both in-game decision-making processes (i.e. decision evaluation, player intention during game-play) and umpire performance (i.e. knowledge of game-play). These themes contributed to the development of decision-making heuristics for Australian football umpires. This study provides initial evidence of the factors that may contribute to and/or affect in-game decision-making processes; however, additional exploration is necessary to further inform training programmes aimed to develop domain-specific decision-making skills and subsequent in-game performance. © 2016 International Society of Sport Psychology.

- Description: Sport expertise research provides a robust body of knowledge on the characteristics that separate experts from those less skilled. Perceptual skill is recognized as an important factor in agility performance in team sports like Australian Football (AF). However, perceptual-agility research to date has concentrated on inter expertise skill differences (i.e., elite vs. novice). This study investigated the presence of any intra-group differences within a cohort of elite AF athletes on a simulated perceptual-agility task. Specific aims were to 1) identify if AF athletes predetermined as high agility displayed superior perceptual-agility skill compared to low agility AF athletes, and 2) identify if high experience AF athletes displayed superior perceptual-agility skill compared to low experience AF athletes. Fourteen AF athletes performed a video-based Perceptual-Agility Test (PAT) that assessed the athletes’ decision time and decision accuracy in response to intercepting an attacking player on the projected simulation. Part 1 of the analysis; the athletes were divided into two groups (n = 7 each) by way of median split according to their in-game defensive agility performance scores. T-tests were conducted to reveal any differences between the groups in decision time and decision accuracy (Part 1 and Part 2). No significant differences were found in decision time or decision accuracy between the high and low agility AF athletes. Part 2 of the analysis; the 14 athletes (high experience) were compared to a group of low experience athletes (n = 8) on their PAT performance. No significant differences were found in decision time or decision accuracy between the high and low experience AF athletes. While there were no observable differences within the cohort of elite AF athletes using the predetermined classifications of agility and experience, this study does, however, confirm the difficulty of revealing intra expertise performance indicators using assessment tools that routinely discriminate a priori levels of skill (i.e., expert vs. novice).

J Strength Cond Res. 25(4): 973-979, 2011-Australian football requires frequent intermittent sprinting close to peak running speed. However, tests assessing the capability to maintain intermittent peak running speed are not reported in scientific literature. Therefore, our objective is to report the reliability and validity of a novel intermittent peak running speed test. The intermittent peak running speed test required footballers to perform 10 repetitions on 25-second intervals. Each repetition required 15-m jogging, 20-m acceleration to peak speed, 10 m to sustain peak speed, 20-m deceleration, and finally a 15-m jog. Intermittent peak running speed was determined by portable global positioning system. To assess reliability, 26 footballers performed the intermittent peak running speed test on 2 occasions 3-5 days apart. Our results revealed that average peak speed had a coefficient of variation of 2.2% and an intraclass correlation of 0.91. To assess construct validity, average peak speed was compared between elite, sub-elite, and regional footballers. The average peak speed of the elite footballers (28.6 ± 1.7 km-h-1) was higher than that of the sub-elite (27.4 6 1.7 km-h -1) and regional (27 6 1.9 km-h-1) competitors (p < 0.05). Our study revealed that the intermittent peak running speed test possesses acceptable reliability and distinguishes between elite and sub-elite footballers. © 2011 National Strength and Conditioning Association.

- Description: Repeated sprint training improves intermittent peak running speed in team-sport athletes. J Strength Cond Res 25(5): 1318-1325, 2011-The aim of this study was to compare the effect of 2 repeated sprint training interventions on an intermittent peak running speed (IPRS) test designed for Australian Rules football. The test required participants to perform 10 3 10-m maximal efforts on an 80-m course every 25 seconds, for each of which the mean peak speed (kilometers per hour) was recorded to determine IPRS. The training interventions were performed twice weekly for 4 weeks immediately before regular football training. In the constant volume intervention (CVol), sprint repetition number remained at 10 (n = 9), and in the linear increase in volume (LIVol) intervention, repetition number increased linearly each week by 2 repetitions (n = 12). Intermittent peak running speed, 300-m shuttle test performance, and peak running speed were assessed before and upon completion of training. All measures were compared to a control group (CON; n = 8) in which players completed regular football training exclusively. Intermittent peak running speed performance in CVol and LIVol improved significantly (p < 0.01) by 5.2 and 3.8%, respectively, with no change in IPRS for CON. There were no differences in IPRS changes between CVol and LIVol. Additionally, peak running speed improved significantly (p < 0.01) by 5.1% for CVol, whereas 300-m shuttle performance improved significantly (p < 0.01) by 2.6% for LIVol only. Intermittent peak running speed, 300-m shuttle performance and peak running speed were improved after 4 weeks of training; however, progressively increasing sprint repetition number had no greater advantage on IPRS adaptation. Additionally, exclusive regular football training over a 4-week period is unlikely to improve IPRS, peak running speed, or 300-m shuttle performance.

- Description: AbstractObjectives Australian Football League (AFL) players have a high risk of injury. Anecdotally, this injury risk is greater in emerging players (i.e. those in their first year), compared with established players (with 3+ years of experience). This study aimed to conduct the first comparison of injury risk and playing experience in these two player groups across a large number of AFL clubs. Design Prospective, cohort. Methods Injuries, game participation and training participation were collected weekly by 8 AFL clubs for 61 emerging and 64 established players. Injury incidence rates (IIR) and Cox proportional hazard models for time to first injury, separately for games and training, were computed. Results The game IIR was significantly higher for emerging than established players: 45.6 (95% CI: 35.7, 57.6) versus 18.3 (95% CI: 13.1, 24.9) per 1000 game-hours. Emerging players also had a higher training IIR than did the established players: 9.6 (95% CI: 7.6, 11.9) versus 8.9 (95% CI: 7.0, 11.1) per 1000 training-hours. Emerging players were significantly less likely to remain injury free in games than established players (HR = 3.46, 95% CI: 1.27, 9.45). A similar outcome was seen in training sessions, although to a lesser degree (HR = 1.41, 95% CI: 1.19, 1.69). Conclusions Despite efforts to modify the playing/training program of emerging players, this group remain at greater risk of injury in games and training sessions, compared with established players. Continued efforts should be made toward understanding reasons for this increased risk to better prevent injury during the early years of a professional football career.

- Description: The developmental histories of 32 players in the Australian Football League (AFL), independently classified as either expert or less skilled in their perceptual and decision-making skills, were collected through a structured interview process and their year-on-year involvement in structured and deliberate play activities retrospectively determined. Despite being drawn from the same elite level of competition, the expert decision-makers differed from the less skilled in having accrued, during their developing years, more hours of experience in structured activities of all types, in structured activities in invasion-type sports, in invasion-type deliberate play, and in invasion activities from sports other than Australian football. Accumulated hours invested in invasion-type activities differentiated between the groups, suggesting that it is the amount of invasion-type activity that is experienced and not necessarily intent (skill development or fun) or specificity that facilitates the development of perceptual and decision-making expertise in this team sport. © 2008 Human Kinetics, Inc.

There were 113 children (46% girls, 49% intervention) with a mean age of 9.4 years (SD = 1.8) that participated. Intervention children underwent 8 weeks of gymnastics and the comparison group continued with their standard curriculum. Age was a significant co-variate, a separate analysis was conducted on the lower (grades 2 and 4) and upper (grade 6) groups. The lower age group showed significant improvement in favor of the gymnastic group in fundamental movement skills. The upper age group showed a significant improvement for the control group in general body coordination and fundamental movement skills. For all grades, the physical self-concept showed a significant main effect in favor of the gymnastics group. The gymnastics intervention was found to be of particular benefit for developing children's movement competence and physical self-concept in younger children.

Six week prospective study design. Twenty-one data sets were recorded from nine individual players that completed the yo-yo IR2, and played an Australian Football League match in the first five rounds of the 2010 season wearing a global positioning system (GPS) unit. Simple mediation modelling was used to analyse the inter-relationship between yo-yo IR2 score, match exercise intensity and AF performance. Playing position and experience were also incorporated into the model to identify conditional affects. A significant direct relationship was observed between yo-yo IR2 and number of ball disposals (p<0.1) and a significant indirect relationship was observed between yo-yo IR2 and number of ball disposals through distance travelled at high intensity (HIR mmin-1) (p<0.1). Moderation analysis showed that playing position affected the relationship between of yo-yo IR2 and HIR mmin-1 (p<0.1) and HIR mmin-1 and total ball disposals (p<0.1). Playing experience also significantly affected the relationship between HIR mmin-1 and total ball disposals. This study is the first to identify the effects of yo-yo IR2 on total ball disposals through HIR mmin-1 performed during AF matches, and that playing position and playing experience affect these interactions. © 2011 Sports Medicine Australia.

- Description: Decision-making is a central component of the in-game performance of Australian football umpires; however, current umpire training focuses largely on physiological development with decision-making skills development conducted via explicit lecture-style meetings with limited practice devoted to making actual decisions. Therefore, this study investigated the efficacy of a video-based training programme, aimed to provide a greater amount of contextualised visual experiences without explicit instruction, to improve decision-making skills of umpires. Australian football umpires (n = 52) were recruited from metropolitan and regional Division 1 competitions. Participants were randomly assigned to an intervention or control group and classified according to previous umpire game experience (i.e., experienced; less experienced). The intervention group completed a 12-week video-based decision-making training programme, with decision-making performance assessed at pre-training, and 1-week retention and 3-week retention periods. The control group did not complete any video-based training. Results indicated a significant Group (intervention; Control) x Test interaction (F(1, 100) = 3.98; P = 0.02, partial 2 = 0.074), with follow-up pairwise comparisons indicating significant within-group differences over time for the intervention group. In addition, decision-making performance of the less experienced umpires in the intervention group significantly improved (F(2, 40) = 5.03, P = 0.01, partial 2 = 0.201). Thus, video-based training programmes may be a viable adjunct to current training programmes to hasten decision-making development, especially for less experienced umpires.
