Key-Performance Indicators in Football (Soccer) and How to Use Them
Using player tracking metrics has become almost mandatory in pro football. They may not guarantee success. Yet, knowing which key performance indicators to use and how to combine them helps evaluate athletes’ performances, prevent injuries, and lead them to peak performance.

Key performance indicators lay the groundwork for tracking players’ performance effectively. Yet, attributing the same key metrics to every player in the exact same way will not work. Humans are individuals. Athletes react individually to practice and games.
Also, coaches have differing focuses. While one may favor an overpowering style of football, another may be looking to dominate opponents through possession and passing.
Hence, a single metric can be the first dot. Only by looking at volume‑, intensity‑, internal-and external data altogether, by contrasting mechanical and metabolic load and connecting all those dots over a range of time, is it possible to paint a player’s performance picture.
Martin Krüger, Union Berlin’s athletics coach, explains why metrics played a crucial role in the club having the least days missed due to injury during the first half of the current Bundesliga season.
Performance Tracking: Football’s Demands for Players
Taking all that into account is particularly vital in football, where players cover around 10km at an average speed of 7km/h, about 1.5km at high intensity. Add about 20 sprints per game, and you get a mix of endurance and explosiveness.
Players need to change directions quickly, sometimes at almost full speed. They must stop or accelerate on the spot while covering lots of ground. That may lead to overload – – and injuries. Especially to the knees, ankles, and muscles.

Finding and defining the right metrics as a combination of volume vs. intensity based ones, is the crucial part by working with data. With the help of our Sport Scientists we support coaches by understanding their needs and help them setting up the right strategy to analyze the data.
The Benefits of Player Tracking and Load Management in Football
Therefore, by tracking specific key performance indicators over a week, month or season, coaching staffs can monitor whether a player differs from their usual performance. Plus, it becomes apparent if an athlete stagnates despite training designed to stimulate a spike.
Compared to practice metrics, match data can indicate whether a player can apply the training efforts during a game. Match metrics also help manage load, as coaches can use them as a reference point to aim at certain intensity levels during the practice week.
Through live tracking, that process becomes even more agile: coaches witness how specific exercises impact their players’ performance in real-time. If the metrics indicate too much or a lack of intensity, coaches can adjust immediately.
Key Player Metrics in Football
For in-depth analysis, all metrics need to be applied with a player’s position in mind, for the game’s requirements for a center-back differ from those for a winger, for example. The following key-performance indicators facilitate that process:
- Acceleration Load: Adding up different acceleration data like movements, jumps and bumps to one single number, the data indicate what a practice demands from the athlete’s body and possible overload: the higher the acceleration load, the more intense the training session or exercise.
- Combine With: distance covered in high-intensity ranges.
- Total distance: basic volume metric that does not tell much if looked at in isolation.
- Combine with: acceleration load and heart rate metrics or TRIMP.
- Sprints: high-intensity metric tracking how often and long a player sprints during practice. With repeated sprints being crucial in football, monitoring them over time indicates whether training is effective and how it affects the players’ match performances.
- Combine with: internal load metrics to determine how demanding training sessions are and manage the load.
- Training Impulse (TRIMP): Indicating internal load, TRIMP helps track a training session’s demands from the player. It uses the average minimal and maximum heart rate and the session’s duration. The benefit: coaches can determine whether an athlete needs more aerobic or anaerobic workouts. Plus, they can compare the demands of training and match and see if a specific exercise meets the TRIMP values of a match. Analyzing values over time allows staffs to spot a player’s exhaustion and overload.
- Combine with: external metrics to track the demands that training sessions put on players.
Metrics like decelerations, accelerations, and impacts become very meaningful to me, whereas someone focused on optimization might focus on speed zones and maximum achieved statistics.
KINEXON’s Role in Player Tracking
Offering ball-and player tracking, KINEXON Football provides all the metrics coaching staffs need to evaluate their players’ performance. Being incredibly precise and supplying metrics 3‑dimensionally in real-time, KINEXON player tracking solutions help design training sessions more effectively.
That helps prevent injuries, and players get assistance to peak at the right time. For more insights, explore our recent case study with Union Berlin. As in the previous season, no club has fewer injuries in the first half of the current Bundesliga season than Union Berlin. Martin Krüger, Union’s Athetic Coach, is certain that tracking data has played an important role.
