Aerobic base
The ability to sustain manageable effort and return to ordinary activity between sessions. It describes a broad capacity, not a personal target or diagnosis.
REFERENCE DESK
Words that make movement clearer.
A glossary is useful when a familiar word carries a technical meaning. Navlin defines terms in plain language and explains where an idea belongs, where it stops, and what question it can help a reader ask.
How to use a definition
Definitions are starting points, not complete answers. A term may be used differently across research, coaching, clinical, and everyday settings. Read the example and the limitation together. If a word appears in a personal report, test result, or professional recommendation, ask the person responsible for that context to explain how they are using it.
- Read the short definition.
- Notice the example and setting.
- Check the related terms.
- Ask what the word does not establish.
A precise word cannot decide for a person, but it can make the next question easier to ask.
Cadence
The frequency of repeated movement, such as steps or pedal turns, usually described alongside pace, terrain, and comfort.
Functional strength
Strength considered in relation to a useful task, movement control, and the demands of daily or recreational life.
Mobility
The ability to move through a range with control and context. It is not simply a measure of flexibility or a performance score.
Perceived effort
A person’s description of how demanding an activity feels, interpreted alongside duration, environment, and other observations.
Recovery
The changing response after activity, including rest, sleep, daily workload, and readiness for another ordinary task.
Terms in relationship
| Term | Often discussed with | Important boundary |
|---|---|---|
| Training load | Duration, intensity, frequency, response | It does not explain the cause of every response |
| Intensity | Pace, effort, breathing, terrain | A number alone may not describe the experience |
| Baseline | Comparison, trend, routine | A baseline changes when context changes |
| Adaptation | Repeated practice and recovery | It should not be treated as a promise of a fixed outcome |
Choosing the right question
Find the noun
Identify the word that is causing confusion rather than searching for a complete answer to every topic at once.
Find the verb
Ask what the term is doing in the sentence: measuring, describing, comparing, preparing, or interpreting.
Find the boundary
Read what the term cannot establish and what additional context would be needed.
Need a term in context?
Send the word and the page where you found it to Navlin at Jalan Sudirman No. 18, Senayan, South Jakarta 12190, Indonesia, or +62 21 7123 8945. Avoid sending private reports or identifying information.
Why definitions change
Language develops as research, practice, and everyday use interact. A definition may be updated when a term has become ambiguous, when readers report confusion, or when a source uses a narrower meaning than the page suggests. Updates are made carefully so that related entries continue to make sense together.
Readers can send a suggested term or ask for a definition in context. Include the page address and the sentence where the word appears, but remove private records and identifying details. Navlin normally acknowledges a question within 7 calendar days and aims to provide a useful response within 30 calendar days.
