HRV Rolling Baseline

Compare current HRV with the prior seven-day mean and caller tolerance.

Description

An HRV baseline screen compares the current value with a lower bound derived from seven prior values.

An HRV baseline screen compares the current value with a lower bound derived from seven prior values. The allowable drop is a supplied fraction.^[1]

Compare current HRV with the prior seven-day mean and caller tolerance.

When to use HRV Rolling Baseline

Use this tool to compare current HRV with the prior seven-day mean and caller tolerance.

Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.

How to use HRV Rolling Baseline 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 baselineHrvMs, currentHrvMs, allowedDropFraction using the field table and calculation rules, then run the tool.
Read baselineMeanMs, lowerBoundMs, belowBaseline. 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
baselineHrvMs	Baseline hrv ms	list of number	Required
currentHrvMs	Current hrv ms	number	Required
allowedDropFraction	Allowed drop fraction	number	Required

Enter exactly seven positive baseline ms values, positive current ms and fraction in [0,1). Return mean, lower bound and strict current<lower flag.

mean=Σ7baseline/7; lower=mean(1−dropFraction)

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

Output field	Meaning	Value type
baselineMeanMs	Baseline mean ms	number
lowerBoundMs	Lower bound ms	number
belowBaseline	Below baseline	boolean

Limitations and assumptions

No HRV metric extraction, artifact correction, readiness decision or individual cutoff calibration is provided.

Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.

Alternative or Complementary methods
