60-Second HR Recovery Drop Checker

Audit actual exactly-60-second HR recovery pairs and caller review criterion, retaining rises; not arbitrary recovery-time interpolation, medical prognosis or safe exertion threshold.

Description

A 60-second heart-rate drop needs a measurement taken at that exact interval.

A 60-second heart-rate drop needs a measurement taken at that exact interval. A rise remains a negative drop.^[1]

The returned values include Signed exactly60 second drops bpm, Observations below caller drop trigger. The How section below explains the calculation, input rules and interpretation.

When to use 60-Second HR Recovery Drop Checker

Use 60-Second HR Recovery Drop Checker when you need to evaluate the supplied records under the calculation and evidence rules below. No interpolation, medical prognosis or safe-exertion threshold is supplied.

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 60-Second HR Recovery Drop Checker 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 observedEndExerciseBpm, observedExactly60SecondRecoveryBpm, callerMinimumDropReviewBpm using the field table and calculation rules, then run the tool.
Read signedExactly60SecondDropsBpm, observationsBelowCallerDropTrigger. 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
observedEndExerciseBpm	Observed end exercise bpm	list of number	Required
observedExactly60SecondRecoveryBpm	Observed exactly60 second recovery bpm	list of number	Required
callerMinimumDropReviewBpm	Caller minimum drop review bpm	number	Required

Enter aligned nonempty positive BPM pairs and nonnegative caller minimum drop. Return signed drops and indexes strictly below the caller trigger.

drop=endExercise−recoveryAt60s

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

Output field	Meaning	Value type
signedExactly60SecondDropsBpm	Signed exactly60 second drops bpm	list of number
observationsBelowCallerDropTrigger	Observations below caller drop trigger	list of number

Limitations and assumptions

No interpolation, medical prognosis or safe-exertion threshold is supplied.

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 Resting HR Fitness Trend Checker: Baseline and recent resting-heart-rate samples can reveal a signed mean change. A caller review trigger is not a diagnosis. For a complementary task, use Run Heart-Rate Training Zone Tool: Maximum-heart-rate percentage zones differ from heart-rate-reserve zones. Caller intervals can overlap or leave gaps.
