Work-Rest Cycle Energy Expenditure Average Calculator

Audit actual heterogeneous work/rest phase energy exposure and separately classified rest time; distinct from inverting an allowed mean, no endurance or sustainable-work guarantee.

Description

A mixed work/rest cycle uses time weighting to combine metabolic demand.

A mixed work/rest cycle uses time weighting to combine metabolic demand. Rest classification and its energy rate are separate evidence.^[1]

Enter aligned nonempty nonnegative energy/duration lists and binary rest flags with positive total minutes. Return weighted watts, rest fraction and cycle duration.

When to use Work-Rest Cycle Energy Expenditure Average Calculator

Use Work-Rest Cycle Energy Expenditure Average Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No endurance, sustainable workload or individual rest prescription is established.

Prepare measured task, body, furniture or already weighted exposure records. Supply independently verified caller policies, tables and comparison limits with matching units and conditions.

How to use Work-Rest Cycle Energy Expenditure Average Calculator and understand its results

Prepare measured task, body, furniture or already weighted exposure records. Supply independently verified caller policies, tables and comparison limits with matching units and conditions.
Enter phaseEnergyWatts, phaseDurationsMinutes, restPhaseFlags using the field table and calculation rules, then run the tool.
Read timeWeightedCycleEnergyWatts, restFraction, totalCycleMinutes. 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
phaseEnergyWatts	Phase energy watts	list of number	Required
phaseDurationsMinutes	Phase durations minutes	list of number	Required
restPhaseFlags	Rest phase flags	list of number	Required

Enter aligned nonempty nonnegative energy/duration lists and binary rest flags with positive total minutes. Return weighted watts, rest fraction and cycle duration.

average=sum(watts×minutes)/sum(minutes); restShare=sum(restFlag×minutes)/sum(minutes)

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
timeWeightedCycleEnergyWatts	Time weighted cycle energy watts	number
restFraction	Rest fraction	number
totalCycleMinutes	Total cycle minutes	number

Limitations and assumptions

No endurance, sustainable workload or individual rest prescription is established.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Metabolic Rest Allowance Percent Calculator for Static Posture: A work/rest energy model can invert a chosen average-demand ceiling. It addresses metabolic averaging rather than static-posture mechanics. For a complementary task, use Mark Versus Full Out Energy Budget Rehearsal: Marked and full-out rehearsal effort can use distinct measured unit rates. The budget is in the caller’s calibrated units.
