Return to Training Performance Calculator

Stage a transparent weekly return-to-training load using reduction, readiness, symptoms, and a capped progression rate.

Re-entry workload plan

Stage a conservative ramp from the first week back to the prior baseline

The plan applies the entered reduction, readiness factor, symptom modifier, and weekly progression. It is a transparent scenario—not medical clearance.

Progression staircase

Weekly load against the previous baseline

Detailed calculation process

Apply independent modifiers once, then compound only the planned progression

General formulas

qreduction = 1 − r/100qready = R/100qsymptom = max(0, 1 − s/10)L1 = L0 × qreduction × qready × qsymptomLw = min[L0, L1(1 + g/100)w−1]Ltotal = Σ Lw

Practical examples

Planning scenarios

  • Model a four-week layoff with a reduced first week and gradual rebuild.
  • Compare how symptom and readiness inputs change only the starting dose.
  • Extend the horizon to see when the entered progression could reach baseline.

Decision checkpoints

Reassess rather than auto-progress

  • Stop or reduce load when symptoms worsen during or after training.
  • Progress only after the current week is tolerated and recovery is acceptable.
  • Use sport-, tissue-, and clinician-specific criteria where injury or illness is involved.

Limitations and safety note

No universal percentage ramp is safe for every athlete or condition. The symptom modifier is a planning device, not a validated clinical scale. The model does not diagnose readiness or account for injury type, tissue healing, detraining, medication, competition demands, or session distribution. Seek qualified medical and coaching guidance after injury or illness.

Return to training FAQ

Why is the starting load modified three times?

The entered reduction, readiness, and symptom values represent distinct user assumptions. They are shown separately so the reduction is auditable.

Does “baseline restored” mean full fitness?

No. It only means the planned AU total reaches the entered pre-break weekly load.

Why cap the progression at baseline?

This page models return to the prior level. A later performance-building block should be planned separately.
