Assessing the macroscopic order therefore suggests successful characteristics in collective behaviour patterns in attacking phases involve a fast ball delivery to a receiver within a close distance [26]. Challenges may arise given a lack of clarity (i.e. Behaviours are typically recorded through annotation software; however, advancements in video capture technologies are allowing player position information to be analysed with associated behaviours to provide a more meaningful understanding of game behaviours. There are some notable studies that have explored the performance processes in rugby union. Rodrigues M, Passos P. Patterns of interpersonal coordination in rugby union: analysis of collective behaviours in a match situation. However, it is important to consider that data were not explored in relation to opposition game style for each specific match. It is a practice-based programme to prepare you for a career in the Rugby and Sports Industry. The period from 2003 to 2007 was the most heavily investigated time interval, with 2003 representing the most popular year of analysis (Table 1).

Recently, researchers have used clustering approaches to identify important patterns in match data associated with certain game outcomes [35, 42]. The method of selection utilised by the investigators included the following: a collaboration with investigators and coaches and/or experts; those selected solely by the research group; those sourced from a third-party company; and those where the method of selection was not stated. Finally, the advancements in other team sports are discussed to illustrate the potential of a range of performance analysis methods that assess team properties and patterns that characterise their organisation. Possession kicked was positively related to performance in three separate studies [22, 25, 37] at the international and Super Rugby level of competition. 2009;9:35467 https://doi.org/10.1080/24748668.2009.11868492. Hum Mov Sci. Critical information may, therefore, be lost if performance-related variables are not contextualised and measured while considering these factors [44]. Duties of a sports analyst include providing pre-game, in-game, or post-game commentaries, making predictions or forecasts, assessing the performance of various athletes, and interviewing coaches, doctors, athletes, and other relevant parties. chad shepherd.

In this approach, important characteristics of complexity are assessed by emergent patterns, due to the interactions between components in the system (i.e. Between 2004 and 2007, winning teams won more lineouts on the opposition's throw, scored more tries, had greater metres gained, kicks out of hand, line breaks and percentage tackles made in international, Super Rugby and professional domestic competitions [17, 22, 23]. Despite the number of studies published in the last two decades, only a few studies have begun to advance the field, while the majority of the studies reviewed involved a reductionist view of performance. 2013;26:413 https://doi.org/10.1007/s11424-013-2285-0.

Although performance analysis research in rugby and data collection has progressed, the utility of the insights is not well understood. Studies were categorised based on the main focus and each study was reviewed by assessing a number of factors such as context, opposition analysis, competition and sample size. https://doi.org/10.1260/174795409790291420. Despite the majority of these articles including context in their analyses, very few accounted for multiple contextual variables, limiting insights into the process of game behaviours due to the player-opponent interaction and the effect of multiple confounding factors, such as field location, number of players involved and period within a match.

These methods have been applied to develop a deeper understanding into collective system measures providing valuable insights into sports such as football and basketball.

Sports such as football, basketball and AFL have adopted dynamical system approaches in their analysis of tactical performance; however, there is limited understanding of the value of such approaches in a gain line team sport, such as rugby union, where teams in possession of the ball aim to gain ground relative to the initial starting position, referenced by a projected line that runs parallel to the try line known as the gain line. 2014;14:S817 https://doi.org/10.1080/17461391.2011.635812. In fact, 22 of the 41 studies retrieved focused on descriptive and comparative statistics and often lacked context. Relative predictors of success included an effective kicking game, ball carrying abilities and not conceding penalties when the opposition are in possession. Five studies considered rugby union as a dynamical system; however, these studies were limited in analysing lower or national-level competitions. Passos P, Arajo D, Davids K, Gouveia L, Milho J, Serpa S. Information-governing dynamics of attackerdefender interactions in youth rugby union. Studies utilising performance indicators were additionally assessed to establish the genesis of performance indicators and inclusion of operational definitions. When interpersonal distance decreases, these systems evolve from a state of balance to critical performance moments, as the contextual dependency rules governing performance require constant co-adaptations of each player to their opponent [50, 51]. J Sports Sci Med. https://doi.org/. Studies were assessed based on a number of elements such as context, opposition analysis, competition and number of events analysed. Social network theories have also been used to develop a deeper understanding of the passing interactions between team members that demonstrate the local interactions within the wider system [66, 67]. When articles were grouped into year of data collection and analysis, ~ 50% of the articles analysed data from games played between 2000 and 2008 (Fig. Of the 22 articles that contextualised their measures of performance, only five accounted for multiple contextual variables.
