About TRI
Based in Dortmund, Germany, the Tennis Research Institute bridges elite sports science and competitive court reality. We translate advanced biomechanics, kinetic-chain analysis, and real-match data into clear, actionable development strategies for players, coaches, and performance teams worldwide.
Bridging science and court performance
TRI was founded to establish an objective, evidence-based approach to tennis performance. Traditional coaching and standard sports laboratories often operate in silos. We bridge this gap by capturing elite players directly at premier professional tournaments and competitive environments, analyzing biomechanics, movement patterns, and tactics where it matters most.
The ATP Serve Catalog and elite research
One of our landmark achievements is the TRI ATP Serve Catalog, developed over two years through rigorous analysis of more than 40 top tour professionals—including Jannik Sinner, Alexander Zverev, Daniil Medvedev, and Taylor Fritz. We analyze the complete kinetic chain: rhythm, toss consistency, leg drive, rotation, and racket acceleration to uncover hidden margins of performance.
Collaborate with our research team
Bring us a specific player, mechanical issue, or tactical performance question. Utilizing our extensive ATP, WTA, Davis Cup, and United Cup databases alongside high-tech video and biomechanical diagnostics, we transform subtle technical nuances into direct, teachable training cues that elevate competitive performance.
"TRI goes beyond standard coaching observation. Their biomechanical clarity and elite tournament data reveal the precise adjustments that make a measurable difference on court."
