Defense Dynamics
Defense Dynamics presents measured and interpreted movement patterns within software-detected defensive context. It describes movement organization without determining tactical intent, prescribing actions, or judging the athlete.
What this report is
Defense Dynamics analyzes how movement metrics and derived findings appear during segments classified by the software as defensive context. References to response, distance control, balance, recovery, or pressure describe the analyzed movement pattern, not the athlete’s intention, strategy, or decision quality.
The report combines objective measurements with contextual interpretation. A diagnosis or finding must not be converted by itself into a technical, tactical, strategic, medical, psychological, or human verdict. It does not identify the correct fencing decision or determine why the athlete acted.
Available modes
Static
A Static Defense Dynamics report is based on one eligible video containing sufficient software-detected defensive context. It presents aggregated movement findings from that material.
Longitudinal
A Longitudinal Defense Dynamics report requires at least 5 eligible comparable videos. It evaluates trend (Progress, Flat, or Regress) and constancy (Consistent or Inconsistent) within that comparable set.
Contextual Versus uses one eligible video to compare the reference athlete in defensive context with the opponent in the corresponding attacking context.
Input requirements
Static report
Use 1 eligible video where the defensive action, athlete body, weapon hand, weapon line, and relevant opponent interaction are sufficiently visible.
Longitudinal report
Use 5+ eligible comparable videos of the same athlete, preferably with similar camera angle, visibility, defensive context, and recording quality.
Contextual versus
Use 1 eligible film where both athletes are visible enough for comparison. Opposite movement contexts must be identifiable in the selected action.
Video quality matters
Every uploaded video must show both fencers, be no longer than 15 seconds, have a minimum resolution of 720p and a minimum frame rate of 30 fps, and be supplied only as an MP4 or MOV file. Poor framing, occlusion, blur, camera instability, or insufficient weapon or body visibility may reduce reliability, produce partial output, or make the video ineligible. Review the Video Recording Guide before uploading.
Contextual versus analysis
Single film
In contextual versus, the comparison is made on a single film.
Reference athlete
A reference athlete is selected for the report view. If the reference side is analyzed in offensive context, the opponent side can be analyzed in defensive context, and vice versa.
Metrics and states
Only metrics with valid measured values for both athletes are compared. Differences are relative to the analyzed recording and are interpreted only according to the report thresholds. Bad, Average, and Good are metric states, not rankings. A small or negligible difference between two Bad states does not establish a tactical advantage or general superiority.
How to read this report
Read it as an aggregated defensive view
This report should be read as an aggregated interpretation of defensive movement, not as frame-by-frame labeling, coaching advice, or a replacement for the general reports.
Use it when the question is defensive
It is most useful when you want to review how selected findings appear in defensive response organization, defensive-context consistency, and pressure-related behavior.
Common report logic
Phenomenon
The measured or interpreted movement pattern identified within software-detected defensive context.
Causes
Plausible biomechanical factors that may be associated with the identified contextual pattern.
Effects
How the identified pattern may influence movement organization, control, stability, or consistency within the analyzed defensive context.
Interpretation boundaries
Defense Dynamics is an AI-assisted analytical software output. It does not provide personalised coaching, tactical or training prescriptions, medical or legal advice, official refereeing decisions, rankings, predictions, or guarantees of performance or improvement. It does not replace qualified professional judgment.
For consistency across languages, all FencingMonitor report explanations are generated in English. The website interface and legal pages may be available in other supported languages.
How it differs from the other reports
Compared with Biomech Profile and Issue Dynamics
Biomech Profile and Issue Dynamics remain general. Defense Dynamics narrows the reading to defensive-context movement patterns.
Compared with Offense Dynamics
Defense Dynamics and Offense Dynamics use the same contextual logic, but they read selected findings in opposite fencing contexts.
