Sinclair Coefficient Weightlifting Calculator
Evaluate caller verified Sinclair cycle constants and actual weightlifting mass/total, with unity above reference body mass; no cycle/cohort inference or training recommendation.
Description
Sinclair adjusts a weightlifting total using cycle-specific constants.
Sinclair adjusts a weightlifting total using cycle-specific constants. At or above the reference body mass the coefficient is one.1
The returned values include Caller sinclair coefficient, Caller sinclair total. The How section below explains the calculation, input rules and interpretation.
When to use Sinclair Coefficient Weightlifting Calculator
Use Sinclair Coefficient Weightlifting Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No current cycle, cohort, applicability or training recommendation is inferred.
Prepare the observed race, match or training records and the stated units. Supply independently verified rule editions, calibration tables and targets where requested.
How to use Sinclair Coefficient Weightlifting Calculator and understand its results
- Prepare the observed race, match or training records and the stated units. Supply independently verified rule editions, calibration tables and targets where requested.
- Enter observedLifterBodyMassKg, observedWeightliftingTotalKg, callerVerifiedSinclairReferenceBodyMassKg, callerVerifiedSinclairCycleCoefficient, callerCoefficientCycleId using the field table and calculation rules, then run the tool.
- Read callerSinclairCoefficient, callerSinclairTotal. 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 |
|---|---|---|---|
| observedLifterBodyMassKg | Observed lifter body mass kg | number | Required |
| observedWeightliftingTotalKg | Observed weightlifting total kg | number | Required |
| callerVerifiedSinclairReferenceBodyMassKg | Caller verified sinclair reference body mass kg | number | Required |
| callerVerifiedSinclairCycleCoefficient | Caller verified sinclair cycle coefficient | number | Required |
| callerCoefficientCycleId | Caller coefficient cycle id | string | Required |
Enter positive lifter/reference masses, nonnegative total/cycle coefficient and nonblank cycle label≤128 characters. Return coefficient and adjusted total.
coefficient=1 above reference else10^(cycleCoefficient×log10(mass/referenceMass)²) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| callerSinclairCoefficient | Caller sinclair coefficient | number |
| callerSinclairTotal | Caller sinclair total | number |

}Limitations and assumptions
No current cycle, cohort, applicability or training recommendation is inferred.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Extremely large text inputs are rejected. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Wilks Coefficient Calculator: Wilks normalizes a lifting total using a body-mass polynomial tied to a verified edition and cohort. Coefficients and applicability must be supplied explicitly. For a complementary task, use DOTS Score Powerlifting Calculator: DOTS uses a fourth-degree body-mass denominator tied to a verified edition and cohort. It differs from Wilks’ fifth-degree form.
