Private Performance Analysis
Turn a great moment into repeatable performance.
For J.League players, players aiming for J1, J2 or J3, regional league and F.League players, overseas academy players, college players, elite youth players and players preparing for trials or tryouts. We identify why a great action worked and what the player needs in order to reproduce the same quality again.

Repeatable Performance
Doing it once does not make it a weapon.
A shot that worked once in a match. A first touch that felt perfect in training. A burst of acceleration or one-on-one action that appeared only on one day.
If the player cannot explain why it worked, it is difficult to reproduce the same action under pressure, fatigue and match conditions.
We compare the successful action with the action that could not be repeated, then identify the technical and movement conditions needed for repeatability.
For Players
For players aiming at J.League, regional leagues, F.League, overseas clubs, academies, trials and tryouts.
- The quality of the shot changes from match to match
- The player cannot repeat their best first touch
- It works in training but not at match speed
- The first step is not consistently sharp
- Running form changes when tired
- The player becomes tense in contact situations
- The ball is lost when pressure increases
- Movement feels different after returning to play
- Similar technical problems keep returning
- The player does not fully trust their body in matches
- The difference between good and bad days is unclear
- Match video shows the result, but not the reason
Analysis Process
Before adding more training, we identify what changed.
Observe the action
We review match video, training video and the player’s own feeling to clarify what is happening.
Compare good and bad moments
We compare timing, preparation, body position and execution between successful and unsuccessful actions.
Separate the causes
Breathing, vision, posture, centre of gravity, foot contact, arm use, tension and distance from the opponent are checked.
Build repeatable conditions
We organise what the player should feel, check and execute in order to reproduce the same quality.
Check the change
The change is checked through movement, video, or the next match footage whenever possible.

Movement Analysis
The visible problem and the actual cause are not always in the same place.

Acceleration
We check foot contact, posture, arm use and how force is transferred into the first step.

Ball Impact
Support foot, hip position, ankle, timing and distance from the ball are examined.
What We Analyse
The problem you see is not always where the cause is.
Return to Play Movement
Not medical treatment. Football movement analysis.

Some players return to training but still cannot move with the same confidence. Acceleration, deceleration, cutting, body trust and fatigue response may feel different.
This service does not provide medical diagnosis, treatment, prevention or rehabilitation. We analyse football movement and technical execution: acceleration, deceleration, foot contact, posture, breathing and force transfer.
Players with pain, injury, post-surgical limitations or restricted activity should follow the decision of a qualified medical professional before participating in any physical session.

FAQ
Frequently asked questions
Can we consult without notifying the club?
Yes. Player name, club name and consultation details are not shared publicly without permission.
Is this team tactical coaching?
No. The focus is the player’s own technical movement, performance conditions and repeatability, not team tactics.
Can video alone be analysed?
Yes. It helps to provide both a good moment and a moment where the same action could not be repeated.
Can returning players use this service?
Yes, when the player has appropriate clearance for activity. This is football movement analysis, not medical treatment or rehabilitation.
Start privately
Make the good action repeatable.
Before changing everything. Before adding more training. First, identify why the good action happened and why it could not be repeated.
