Coaching as diagnosis-intervention-reassessment

A 2026 Journal of Sports Sciences paper used detailed microethnographic analysis of an actual Muay Thai developmental bout rather than studying athletes through laboratory tasks. The researchers identified five recurring coaching functions: diagnosis, strategy, implementation, affirmation, and consolidation.

While this study was limited to a single coaching environment and not evidence it's an optimal method, it is ecologically valid. These ideas can expand beyond sports matches and become a part of kumite practice or any free-style interaction. Use these interactions to improve your coaching eye and cues as much as the students' skills.

The basic idea is that coaching is not simply transferring technical knowledge into the athlete. Watching the athlete-opponent system to identify what is currently limiting performance, intervening, and using the subsequent behavioral responses as new information is the key.

Failure modes tend to be in perception, decisions, position, execution, confidence, or how the opponent adapts, not just the technique.

Observe-diagnose-cue supports changing one thing and seeing whether the system (athlete-opponent) improves.

When you, as coach, see a missed opportunity, ask the athlete, "What did you see?" Explore their possible perception error.

When they do something well or something not useful, explore their decision-making. "What was going through your mind when you threw a front kick at a retreating opponent?" Avoid using the term "why?" as it generates defensive answers.

Do something similar with observations related to position, execution, confidence, and opponent adaptation.

Look for one thing to cue. Remember the best cues are short, even a single word, and externally focused.
