When compared to the early 2000s, the technology and methodologies utilized in the study of sports performance have undergone significant changes. In addition to GPS tracking, time-lapsed notational analysis software, a variety of tracking sensors, and other tracking equipment, they also involve the integration of new analytical frameworks and sophisticated statistical modeling. Sophisticated computerized methods and technologies replaced pen and paper shorthand notes, collecting massive amounts of performance-related data nowadays.

The stakes for success have inevitably increased as a result of the growing financial opportunities in most major sports due to the growing global viewership and ever-increasing money from media deals. Consequently, sports organizations are depending more and more on scientific, evidence-based tactics to run their organizations and develop their athletes. Since the bar for success in top sports is always rising, teams, coaches, and athletes are under continual pressure to produce more efficient training plans, enhance athlete development initiatives, and increase their understanding of the factors influencing performance in significant contests.
The very competitive market with steadily declining margins has sparked the emergence of Performance Analysis as a distinct, interdisciplinary backroom function that specializes in the objective, and usually quantitative, evaluation of performance. This relatively new discipline aims to help coaches evaluate which performance areas require attention, the effectiveness of tactical and technical performance, and the benefits and drawbacks of approaching opponents. Its objective is to provide accurate and reliable information to coaches, players, and other relevant stakeholders so they may better understand a particular area of the sport.
In the past, sports performance analysis has been defined as an observational analytical process that includes coaches, players, and analysts themselves. Its objectives range from gathering data to providing comments in order to enhance sports performance. Performance reviews are done using recorded video and other data, or in live time during the tournament. At stadiums, performance analysts are becoming more prevalent. They can be observed recording events and actions throughout the game from the coaching box or another excellent viewing location among the spectators using specialist software like SportsCode, Dartfish, or Nacsport. They generate statistical reports during this process, giving coaches a synopsis of key performance metrics and quick video feeds of significant moments, which they may see on their iPhones or iPads. The coaches’ gadgets may receive these reports instantly. However, post-match analysis has more time at its disposal, allowing for a more comprehensive evaluation of performance using other data sources. Post-match analysis can make use of other data sources in addition to the analyst’s observations. These sources range from video recordings and qualitative data to measurements taken by wearable equipment that track an athlete’s location, heart rate, blood lactate levels, acceleration, and speed. While the club will often provide some of this data, internal databases in a number of sports are often supplemented by outside sources, such as Opta. In order to help coaches plan the next session and offer information for debriefing sessions, analysis of training sessions is also conducted, with athletes being observed continually.
Furthermore, the discipline’s research has grown into a separate area of study. At the moment, studies on significant sports analysis research topics are regularly published in the International Journal of Performance Analysis in Sport. These topics include the identification of key performance indicators, injury prevention through physical and work-rate analysis, movement analysis, the efficacy of technique and tactics, normative profiling, overall match analysis, and even referee performance analysis.
Performance Evaluation: A Different Backroom Position
Over the past 20 years, performance analysis has emerged as a crucial part of the extrinsic feedback process that coaches utilize in many elite sports teams and companies to assist players reach their optimum performance levels and accelerate learning. With its major focus on quantitative performance evaluation, it has distinguished itself from other sports science fields and is now recognized as playing a unique function within a team’s backroom personnel. It must, however, maintain strong connections with other sports science fields due to its high degree of cross-functionality. For example, a work-rate study by a strength and conditioning department might be a helpful supplement to the work of a performance analyst team to help with player selection based on player fitness as well as performance data.
The Objective of Athletic Performance Evaluation
Coaches must properly distribute and show a large number of quantitative and qualitative data created by the complex and dynamic situations in sport in order for them to swiftly obtain insight into areas that require their attention. During this procedure, it is best to employ clear visual aids like tables, charts, or specialized representations of the playing field. Performance analysis enhances the coach’s ability to “feed-forward.” Through comprehensive opposition analysis, it aims to predict an opponent’s advantages and disadvantages and furnish information that allows the team to rehearse appropriate plays and refine individual skills to outperform the impending opponent.
Performance analysis studies yield insights that help coaches choose a squad and make tactical decisions that best exploit an opponent’s weaknesses and counter their strengths. One such insight is opposition analysis. In the past, all of these assessments were based on the collective knowledge of coaches who had years of experience in the profession or had competed at the top levels of the sport. However, several studies have consistently demonstrated that coaches are only able to recall 42% to 59% of the critical events that take place during a sporting game. Furthermore, memories of events are prone to incompleteness, emotional bias, inaccuracy, and misinterpretation due to inherent flaws in human perception and cognitive abilities. In an environment that is becoming more and more competitive, coaches have turned to technology and statistics to make up for these limitations. This has made it possible for them to quickly get unbiased data on past occurrences as well as instantaneous video footage for the purpose of analyzing and reassessing certain incidents. Top-tier coaches now have access to their own Performance Analysts departments, which provide them with the tools necessary for data collecting, processing, analysis, and video analysis, allowing them to use the massive volumes of information created by their sport. Additionally, these departments make certain that the most crucial components reach them in an understandable, timely, and succinct way.
