|---|---|---|---|
| Primary | Forced Vital Capacity (FVC) | Baseline (immediately before) and immediately after the single intervention session (same day) | FVC in liters (L), measured with a CHEST HI-801 spirometer. |
| Primary | Resting Minute Ventilation | Baseline (immediately before) and immediately after the single intervention session (same day) | Minute ventilation during quiet breathing in liters per minute (L/min), measured with a CHEST HI-801 spirometer. |
| Primary | Forced Expiratory Volume in 1 Second (FEV1) | Baseline (immediately before) and immediately after the single intervention session (same day) | FEV1 in liters (L), measured with a CHEST HI-801 spirometer. |
| Primary | Peak Expiratory Flow (PEF) | Baseline (immediately before) and immediately after the single intervention session (same day) | PEF in liters per second (L/s), measured with a CHEST HI-801 spirometer. |
| Primary | Maximal Voluntary Ventilation (MVV) | Baseline (immediately before) and immediately after the single intervention session (same day) | MVV in liters per minute (L/min), measured with a CHEST HI-801 spirometer. |
| Primary | Resting Tidal Volume | Baseline (immediately before) and immediately after the single intervention session (same day) | Tidal volume during quiet breathing in liters (L), measured with a CHEST HI-801 spirometer. |
| Primary | Resting Respiratory Rate | Baseline (immediately before) and immediately after the single intervention session (same day) | Respiratory rate during quiet breathing in breaths per minute, measured with a CHEST HI-801 spirometer. |
| Primary | Ventilatory Reserve | Baseline (immediately before) and immediately after the single intervention session (same day) | Ventilatory reserve in percent (%), calculated by the CHEST HI-801 spirometer from resting minute ventilation relative to MVV. |
| Secondary | Standard Deviation of Fundamental Frequency During Sustained Note | Baseline (immediately before) and immediately after the single intervention session (same day) | Standard deviation of the fundamental frequency in hertz (Hz) during a sustained G4 note, extracted with automated pYIN-based acoustic analysis. |
| Secondary | Mean Fundamental Frequency During Sustained Note | Baseline (immediately before) and immediately after the single intervention session (same day) | Mean fundamental frequency in hertz (Hz) during a sustained G4 note, extracted with automated pYIN-based acoustic analysis. |
| Secondary | Lowest Attainable Pitch | Baseline (immediately before) and immediately after the single intervention session (same day) | Lowest fundamental frequency in hertz (Hz) reached during a descending pitch-range task. |
| Secondary | Maximal loudness | Baseline (immediately before) and immediately after the single intervention session (same day) | Peak sound level in decibels relative to full scale (dBFS) during a G major arpeggio played at maximal controllable loudness. |
| Secondary | Highest Attainable Pitch (Hz) | Baseline (immediately before) and immediately after the single intervention session (same day) | Highest fundamental frequency in hertz (Hz) reached during an ascending pitch-range task. |
| Secondary | Highest Attainable Pitch (MIDI Semitones) | Baseline (immediately before) and immediately after the single intervention session (same day) | Highest pitch reached during the ascending pitch-range task, converted to MIDI semitone units. |
| Secondary | Rating of perceived exertion | Baseline (immediately before) and immediately after the single intervention session (same day) | Rating of perceived exertion on the Borg 6-20 scale (minimum 6, maximum 20; higher scores indicate greater perceived exertion, i.e., a worse outcome), rated immediately after a high-register melody task. |
| Secondary | Sustained-note duration | Baseline (immediately before) and immediately after the single intervention session (same day) | Duration in seconds (s) of a sustained G4 note played as long as possible. |
