Study guide: Progression and safety models
Compare gradual paper-plan changes, recovery space and evidence limits.
Ideas to explain in your own words
- A planned duration change is arithmetic, not a universal training prescription. A change from twenty to twenty-five minutes is five additional minutes. Its appropriateness depends on ability, activity, support and conditions; no fixed percentage rule guarantees safety.
- A relative change uses the old value as the denominator. A five-minute increase means different percentages when the starting plan is ten versus twenty minutes. The percentage describes the supplied change; it is not a safe-progression prescription.
- Recovery time in a general plan allows a person to rest and adapt rather than repeat the same demand continuously. The amount needed varies by person and activity. A paper schedule can show rest opportunities but cannot prescribe recovery from an injury.
- A plan should meet its stated knowledge goal, environment constraints and access requirements. A duration total alone cannot establish safe equipment, conditions or appropriate individual load. Use a checklist tied to evidence, not a promise of universal safety.
Useful vocabulary
- Change amount
- New minus old measures change; it does not certify the plan as safe.
- No fixed guarantee
- No single arithmetic increase is a universal safe training rule.
- Original denominator
- Relative increase uses the original value, not the new value.
- No prescription
- A percentage calculation is not a safe training limit or injury guarantee.
- Recovery opportunity
- A rest slot is a planning feature, not treatment for an injury.
- Care boundary
- Do not design a medical return protocol in this lesson.
- Priority
- A timing change does not fix a route or access problem.
- Evidence status
- Distinguish confirmed model defect, supported check and unknown performance.
Watch your reasoning
- No single arithmetic increase is a universal safe training rule.
- A percentage calculation is not a safe training limit or injury guarantee.
- Do not design a medical return protocol in this lesson.
A worked review example
The supplied plan has correct arithmetic, a blocked route and no actual movement observation. The route is a confirmed model defect and should be redrawn. The arithmetic stays supported, while physical performance is unassessed. Changing the minutes does not repair the chair in the route. A useful audit preserves what passed, fixes what is shown wrong and names what the evidence cannot establish.
Make a practice plan
- Draw or explain the four methods using the supplied cases.
- Complete the practice questions before checking each explanation.
- Use the review to locate a specific missed step and revisit that lesson.
- Complete the transfer model; compare its evidence and constraints with the model response.
