Sparform

Sparform is a term used in martial arts training to describe a standardized representation of sparring sessions and related drills. It exists in two related senses: a notation system that compactly describes actions and outcomes within a round, and a digital data format for recording sparring events in machine-readable form.

Etymology: the word combines spar, meaning practice combat, and form, referring to the structured sequence of moves or the formal dataset.

History: The concept emerged in scholarly performance-analysis circles in the late 1990s and has since been adopted by training centers and some analytics tools. It aims to enable cross-style comparisons and reproducible coaching workflows.

Structure: A sparform record typically includes participant identities, round numbers, duration, and a chronological sequence of actions such as jab, cross, hook, kick, block, dodge, and feint, along with stance, distance, and contact level. Each event carries a timestamp and outcome (hit, block, evasion, score). Optional biomechanical data like velocity or acceleration may be captured via wearables. The format supports serialization into JSON, XML, or a compact binary form and can reference video links or sensor streams.

Applications: Sparform data supports performance analysis, coaching feedback, curriculum design, and research in motion recognition and human–machine interaction. It is used to assess technique consistency, decision-making, and reaction times across training sessions.

Limitations: Adoption varies by organization, and the complexity of the model can be a barrier for casual practitioners. Data privacy, standardization across styles, and interoperability with existing video analysis tools remain ongoing concerns.
