Allometric Lift Strength
Normalize lifting performance by a caller-defined body-mass exponent.
Description
Allometric lifting strength divides lifted mass by body mass raised to a chosen exponent.
Allometric lifting strength divides lifted mass by body mass raised to a chosen exponent. The exponent defines the normalization convention.1
Normalize lifting performance by a caller-defined body-mass exponent.
When to use Allometric Lift Strength
Use this tool to normalize lifting performance by a caller-defined body-mass exponent.
Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.
How to use Allometric Lift Strength and understand its results
- Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.
- Enter liftKg, bodyMassKg, massExponent using the field table and calculation rules, then run the tool.
- Read allometricStrength. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| liftKg | Lift kg | number | Required |
| bodyMassKg | Body mass kg | number | Required |
| massExponent | Mass exponent | number | Required |
Enter nonnegative lift, positive body mass and exponent 0–1. Return scaled strength, whose units depend on exponent.
strength=liftKg/bodyMassKg^exponent Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| allometricStrength | Allometric strength | number |

}Limitations and assumptions
No coefficient fit, ranking fairness or standard exponent is supplied.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
