PART 2 – DEEP-DIVE Q&A
Are there any examples of how live data impacted coaching decisions during training?
Fabian Klotz: At Wolfsburg, live data facilitates in-depth communication between the head coach and other coaches, both on and off the pitch. It allows us to see if we need to adjust our training goals, like increasing high-speed running or total distance. For instance, if we notice we haven’t achieved enough in a session, we can extend it. This was particularly evident in our last game, where we focused more on exploration and added a second set of exercises to individualize training. Live data is crucial post-game too, helping us decide whether to reduce the intensity for a session. It enables us to make immediate decisions on the pitch, tailored to the specific demands of the game and transition exercises.
In your standpoint, which metrics are the most crucial in the game?
Paul Nihaus: I believe that while distance is informative for volume, it doesn’t fully capture the game’s essence. Focusing on high-intensity actions like sprint speed, acceleration, and deceleration is more effective. It’s important to consider the context of these actions, whether they’re offensive or defensive. High-intensity actions are crucial for strategies like keeping the opponent away from the goal. These metrics help us assess if we’ve achieved our tactical goals and influence our overall strategy.
Fabian Klotz: For load monitoring and management, I prefer simpler metrics over complex algorithms. There are many metrics available, but I focus on total distance for volume-based metrics and high-speed running, sprint distance, and actions in different speed zones for intensity. I look at the number of accelerations, decelerations, and sprints, keeping it simple to avoid the complexity of varied metrics.
How do athletes handle the transparency of sharing their individual performance data with each other during training games, and how does this affect their mentality, especially when they see variations in their strengths and weaknesses?
Fabian Klotz: We share athletes’ performance data, including comparisons with their peers, on a metric board after runs or matches. Athletes often check their live data during training to gauge their performance. This approach helps them understand their activity levels in games and training, fostering familiarity with key metrics used in both contexts. Weekly reports allow athletes to track their progress, especially useful for those needing extra training. For example, they can see if their sprint distances equal those who played longer, explaining the need for additional exercises.
This is also motivational in rehabilitation, as athletes see their effort reflected in the data. Sharing this information promotes motivation and understanding among athletes and coaches alike.
What are the biggest challenges when it comes to live analysis during games or matches?
Fabian Klotz: The main challenge is managing multiple roles during a game, especially with limited staff. For instance, as the only athletic coach for U19, I handle both sports science tasks and substitutions. This means I can’t always monitor live data continuously; I check it briefly during the game, at halftime, and more thoroughly post-match. This data is crucial for planning additional exercises, especially for substitutes. Ideally, having a dedicated sports scientist constantly monitoring the data would be beneficial, but that’s not always feasible in our current setup.
Paul Nihaus: Echoing Fabian’s experience, this is a common challenge among our clients. While technology aims to simplify this process, the reality is that when you’re focused on one task, others get less attention. In academies with only one sports scientist, it’s challenging to continuously monitor data while also attending to athletes. Staff assistance varies, and on match days, everyone has specific roles, making continuous data monitoring difficult. The goal is to find a balance in using technology effectively during these crucial times.
Among your various clients, have you noticed any distinct cultural differences in approach, such as Spanish teams focusing more on tactics while German teams emphasize the physicality?
Paul Nihaus: The observation isn’t solely based on the country but also on the club’s philosophy. Some clubs focus more on defensive strategies, pressing, and counter-attacks. In contrast, teams in Spain and Portugal often emphasize ball control, making offensive metrics more relevant to them. However, the difference really varies from club to club, as each has its unique philosophy and strategy. This influences their use of tracking technology and player development. For instance, the approach to advancing a player from the under-15 to the under-23 team can differ significantly between clubs, even within the same country.
Are younger players more interested in technology and data compared to senior players, and how does this affect your approach to training and player development?
Fabian Klotz: In managing U19, I’ve found that younger players are more engaged with technology and data, reflecting current digital trends. They’re motivated by data insights, actively analyzing information from wearable devices to enhance their performance. This interest is clear as they frequently approach me for load data post-training. When I have a tablet on hand, they’re eager to review their data immediately, even during breaks in training. This data-focused approach is crucial for setting and achieving their developmental goals.
What additional benefits would the ball technology data offer?
Paul Nihaus: Integrating ball data is crucial for analyzing specific match situations, like understanding ball position during offensive, defensive, and transition phases, and for set pieces. It enhances performance analysis and aids in coaching and player education. For instance, it can reveal how often younger players interact with the ball during training, guiding skill development strategies. In short, ball data can also be valuable in diagnostics and standardized tests, contributing to a holistic approach in player development.
Fabian Klotz: I agree with Paul, especially regarding younger players around 13 to 15 years old. It’s important to track technical aspects like ball touches, passes, and dribbles to understand their technical development.
