health.injury-risk Calculator
Calculates weekly training load, acute:chronic workload ratio, and flags injury risk when the ratio exceeds 1.5. The ACWR injury model predicts that spikes in training load — not absolute load — are the primary cause of overuse injuries.
Inputs
Weekly Km
Reference formula or conversion factor shown for context.
Increase Pct
Reference formula or conversion factor shown for context.
Hard Sessions
Reference formula or conversion factor shown for context.
Rest Days
Reference formula or conversion factor shown for context.
Results
injury risk score
Numerical risk rating — higher typically indicates greater probability of an adverse outcome. The score is only as reliable as the inputs and model assumptions.
weekly volume
The computed three-dimensional volume.
increase rate
The value at the specified point or condition.
hard sessions
Sample size or count used in the calculation.
rest days
Number of rest days recommended per week or training block based on the workout volume and intensity inputs.
10% rule
Reference formula or conversion factor shown for context.
