Talk Test Intensity Screen

Classify self-reported talk-test effort without claiming measured ventilatory thresholds.

Description

The talk test uses reported ability to speak and sing as a simple relative-effort screen.

The talk test uses reported ability to speak and sing as a simple relative-effort screen. It does not measure ventilatory thresholds.^{[1, 2]}

Classify self-reported talk-test effort without claiming measured ventilatory thresholds.

When to use Talk Test Intensity Screen

Use this tool to classify self-reported talk-test effort without claiming measured ventilatory thresholds.

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

How to use Talk Test Intensity Screen 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 canSpeakFullSentences, canSing using the field table and calculation rules, then run the tool.
Read talkTestBand. 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
canSpeakFullSentences	Can speak full sentences	boolean	Required
canSing	Can sing	boolean	Required

Enter both boolean observations and run the classifier. The no-full-sentences condition takes priority even when canSing is true. Return the effort-band label.

not full sentences→vigorous; full sentences and singing→light; otherwise moderate

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

Output field	Meaning	Value type
talkTestBand	Talk test band	string

  "input": {
    "canSpeakFullSentences": true,
    "canSing": false
  },
  "output": {
    "talkTestBand": "moderate"
  }
}

Limitations and assumptions

No heart-rate measurement, exercise prescription or clinical assessment is provided.

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.

Alternative or Complementary methods

Use MET Intensity Bands: Classify MET intensity using caller-selected light/moderate/vigorous boundaries. For a complementary task, use Heart Rate Reserve Zone: Compute Karvonen heart-rate reserve training zone boundaries.
