REST DEFENSE

🗣️„… appears to be the optimal symbiosis to counter pressing!“

What is it? & How can we quantify it?

Cutting edge analysis using Bundesliga tracking data & explainable AI!

EXPECTED BALL GAIN (xBG) to measure defensive success

to be successful in defense:
• press the ball leading player
• create numerical superiority around the ball

OFFENSIVE PLAYING STYLE IN PROFESSIONAL SOCCER ⚽️

•Offensive playing style influences TECHNICAL and PHYSICAL match performance considerably! 🏃‍���️
•SUCCESS is only affected to a small extent by offensive playing style. 🏆

Had fantastic three days at @wcsf2023 in Groningen with the team from @TSGResearchLab & @KITKarlsruhe

Topics we were able to present on

➡️ Successful pressing
➡️ Playing styles
➡️ Effective playing time
➡️ Air pollution & performance
➡️ Curved sprinting
➡️ Biological maturity

With the growing interest in soccer analytics, it can be challenging to sift through all of the content that appeared in 2022. My latest blog post lists the research papers, blog posts, news articles, books, and podcast episodes that I liked the most!

@counterattack9 @Physical_Prep @ForcherLeon @StefanAltmann3 @kempe_matthias We measured pressure using an advanced model based on Andrienko et al. (2017). An oval pressure area was shaped around each attacker. Within this area the pressure increases the closer the defender gets to the attacker influenced by the spatial position of the two.
