Performance analysis has been around for a very long period of time, over forty years now. However, when this field first started, the manner in which performance was analyzed was very different from how it is done today. Back in the day, pens and pencils were used heavily and the amount of data that needed to be crunched was very limited. That changed with the introduction of technology and software for analyzing sports data.
Today, there are several performance indicators that analysts rely on to do performance analysis. Performance indicators refer to a combination or selection of action variables that target to define specific aspects of performance in a certain sport. Performance indicators often relate to successful outcome or performance. Action variables can be placed into several groups, that is, technical, tactical, and physical/physiological.
Teams are usually composed of individual players and how well these players are physically will usually determine their performance in the field. As such, players who are better in terms of their physical appearance will always have better performance. For instance, players who are physically better usually cover more distance in high-speed movement activity. Also, they have better total distance coverage with no ball possession. The players can also sprint much better and dominate in ball possession.
When players have improved physical capacity, they have better technical ability in terms of increased pass rate, which consequently improves performance. Physical output always has a positive correlation with the final league ranking. Teams that have better physical output will always have better comparative performance.
Technical parameters have a lot of significance when it comes to football just like physical parameters do. Technical parameters unlike physical parameters are comparatively easier to measure. Technical parameters include several aspects of a game such as number of shots on goal, number of passes, passes into certain zones, types of passes, and crosses among many others. When it comes to passes, there are several factors that contribute to the overall results. For instance, the number of passes, pass attempts, and correct passes all contribute to positive outcomes at the end of a game.
The type of pass is usually not considered as a performance indicator even though teams that succeed tend to have more passes. They use passes as a tool to create shots and reduce predictability.
Passes into the box tend to increase the number of shots on goal and as such, are counted among the strongest performance indicators. Unsuccessful team may have passes, but the passes are usually outside pre-defensive areas.
วิเคราะห์บอล has so many performance indicators that require analysts to be very careful with how they do their analysis. Ignoring certain factors can lead to a low-quality analysis while overvaluing certain factors can still lead to over-estimated analyses. Thus, as an analysis, you will need to be able to gauge the exact value of a parameter and give it the value that it needs. This is a skill that one learns over time after gaining the necessary experience.
