Adaptation
A change that develops in response to repeated demands and adequate recovery. It is a long-view concept, not a conclusion drawn from one successful session.
REFERENCE
A working glossary for endurance practice.
Words can make training easier to discuss, but a definition is not a diagnosis and a metric is not a verdict. Solace uses the terms below to describe observations, decisions, and context with care.
The glossary is intentionally practical. Each entry explains how a term may appear in an article, what it can help a reader notice, and where its meaning becomes uncertain. Readers should keep the surrounding context visible rather than treating any single word as a complete account.
Availability
The capacity a person has for useful training on a particular day after considering sleep, work, stress, climate, and recent load.
Durability
The ability to repeat a quality of movement or effort as circumstances accumulate. Durability includes decision-making and pacing, not only tissue tolerance.
Strain
The internal cost of an external workload. Perceived effort, breathing, heart rate, and mood can all help describe it, with none providing the whole picture.
Terms in context
| Term | Plain-language meaning | Question to ask |
|---|---|---|
| External load | What was done: distance, time, pace, or resistance | What work was completed? |
| Internal response | How the work was experienced by the person | How did the effort feel today? |
| Progression | A planned change in demand over time | Why is the demand changing now? |
| Deload | A period with reduced training demand | What is the reduction intended to support? |
| Context | The surrounding factors that alter meaning | What else was happening this week? |
How to use a term responsibly
- Describe the observation before naming it.
- State the time period and conditions.
- Separate a pattern from a single unusual event.
- Use cautious language where several explanations remain possible.
- Ask a qualified professional when the question moves beyond general education.
For example, “my pace was slower and effort was higher during a humid afternoon” is more informative than assigning a broad label without context. Good language makes the next decision more visible while preserving room for correction.
“A definition should open a useful question, not close the conversation.”
