Why We Changed Ema Burgic’s Serve to an Abbreviated Motion: A Biomechanical Case Study

The tennis serve is the most complex stroke in the game. It demands explosive power, precise timing, and the seamless coordination of nearly every muscle group in the body — all executed in under a second. Yet most players never reach their true serving potential, not because of a lack of effort, but because of mechanical inefficiencies that go undetected by the naked eye. This is exactly where biomechanics changes everything.

Tennis is one of the most physically demanding sports a child can pursue. The combination of explosive movement, repetitive striking mechanics, and the asymmetrical nature of the sport — where one side of the body works significantly harder than the other — creates a unique set of biomechanical challenges for the developing athlete. Add early specialization, high training volumes, and the pressure of junior competition, and you have a environment where injuries are not just possible — they are almost inevitable without proper movement management. Biomechanics is the tool that changes that equation entirely.
