Performance Form

Performance Form is the movement layer between Phone Sports Video and Personal Athletic Intelligence.

Performance Form is the visible structure of how an athlete organizes movement under real performance conditions, including readiness, timing, balance, recovery, repeatability and preparation for the next action.

Tennis Performance Form describes how a tennis player prepares, reacts, balances, recovers, and becomes ready for the next ball.

Next-Ball Readiness means whether a tennis player is physically prepared for the next shot after the previous action, based on visible movement cues such as split-step timing, first-step direction, contact balance, recovery lag, and court re-entry.

Shot tracking explains what happened to the ball. Performance Form explains whether the athlete was ready for the next action.

SpatialForm uses Performance Form for tennis movement analysis and phone-based tennis movement review through visible movement cues, biomechanics-informed movement analysis, and the TennisMovementAnalysisMatrix.

Performance Form is not paper form, generic posture, architecture, golf shot tracking, medical diagnosis, lab-grade measurement, or a replacement for coaching judgment.
