Video Analyzer

1. Purpose of the Tool

The tool helps coaches and swimmers evaluate race performance using detailed race segment data. After collecting race analysis data with Video Analyzer, the tool helps answer:

1. How was the race performed segment by segment?
2. Which race elements are good, normal, or need development according to the model?
3. What happens if selected race elements are improved in simulation?

The tool works with 50m, 100m, 200m and 400m Long Course swimming events for men and women.

2. Basic Workflow

From App Databank

1. Select Event.
2. Select swimmer from the Official RA Databank.
3. Review automatic analysis.
4. Use simulations if needed.
5. Compare swimmers if needed.

From Video Analyzer File

1. Select Event.
2. Paste data from your external Video Analyzer file. Data must match the selected event order.
3. Click Convert to Memory.
4. Select the entered swimmer from the Mac RA Databank list.
5. Review automatic analysis, simulations and comparison.

For comparison, you can select a world-best swimmer first and your swimmer second, or compare the same swimmer between heats, semifinal and final.

3. Event Databank and Swimmer Selection

At the top of the tool, choose the correct event, for example M100Free, W200Fly or M400IM. After selecting an event, the Event Databank list becomes available.

When a swimmer is selected:

• race data is loaded automatically,
• analysis is calculated automatically,
• simulation tables are updated,
• AI Model Evaluation is updated,
• the first analyzed swimmer is stored as Swimmer A for comparison.

4. Entering a New Swimmer

A coach can enter one swimmer or paste a group of swimmers from an external file. Values must be separated by comma or space and must follow the selected event order.

Click Convert to Memory. The swimmer is added to the current event list, is available immediately for analysis, and is automatically saved to the Mac RA Databank.

5. Result Display and AI Model Evaluation

The result display shows:

• result time in seconds and formatted time,
• result speed in m/s,
• predicted result and predicted difference,
• model-adjusted evaluation for the swimmer’s own result level.

The AI Model Evaluation compares the swimmer’s current segment speeds with model-balanced segment speeds for the same result level. It helps answer whether the race elements are balanced.

Grade scale: Good, Normal, Slow. Slow means that this segment should be developed toward the model-balanced expectation.

6. Simulation Tools

Live Update Simulation allows real-time result testing by manually adjusting race segment values. Result Simulation creates possible improvement scenarios.

• Balance Scenario: distributes improvement across race elements in a balanced way.
• Importance-focused Scenario: prioritizes the elements the model considers most important.
• Swim-focused Scenario: focuses improvement on swim segments.
• Turn-focused Scenario: focuses improvement on turn segments.

The radar graph and AI Model Evaluation can be watched together with simulations to understand whether changes move the swimmer toward perfect Model race profile.

7. Comparison Section

The Compare Race Analyses section compares two swimmers or two performances. The first analyzed swimmer becomes Swimmer A — Main. The next analyzed swimmer becomes Swimmer B — Current.

1. Select first swimmer. This swimmer becomes Swimmer A.
2. Select second swimmer.
3. Click Compare.
4. Review segment time differences, grades (Related Elite Swimmers)and comparison graph.

Clear Comparison removes Swimmer A and Swimmer B. The next selected swimmer becomes the new Swimmer A.

8. Databank Protection

The tool uses two databank layers:

Both sources appear as two separate groups in the Event Databank list and are ordered by result rank.

Delete Stored Swimmer erases swimmers only from the Your private local Mac RA Databank. Official RA Databank swimmers are protected and cannot be deleted inside the app.

9. Measuring Notes

For consistent analysis, the same segment definitions must be used every time.

• Start: start signal to head crossing 15m line.
• Swim segments: 10m segments for 50m/100m races, 30m segments for 200m/400m races.

from head crossing 15m line after start until 5m before the turn wall and from head crossing 15m line after each turns until 5m before the next turns wall

• Turn segments: 20m, from 5m before the wall to 15m after the wall.
• Finish: From head crossing last 5m line before finish to hand touch the wall.

10. Recommended Coach Interpretation

The tool should be used as a positive coaching support system. The most useful interpretation is:

• Which segments are already good?
• Which segments are normal for this result level?
• Which segments are still need developing?
• What changes create the perfect Model race profile?

The main purpose is to help coaches and swimmers understand race performance and plan development in a clear, practical and positive way.
