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.
