Mobilisation readiness state and the frequency structure of heart rate variability

TL;DR

This study identifies new frequency components in heart rate variability linked to mental readiness, proposing a potential mathematical model for assessment based on these oscillations.

Contribution

It discovers two novel oscillation phenomena in heart rate variability and links them to mental readiness, introducing a new approach for assessment.

Findings

Identified two new heart rate oscillations with periods of 3 and 4 beats.

Found correlation between 3-beats oscillation amplitude and mental readiness.

Suggested a mathematical model for assessing mental readiness from heart rate data.

Abstract

A number of studies showed association of mental status with heart rate variability. This work discovered a feature of frequency structure of heart rate variability that is associated with mental readiness. In three independent groups of 64, 39, and 19 volunteers by the factor analysis of heart rate periodograms, it has been discovered that there are at least two other heart rate oscillation phenomena apart from the well known low frequency oscillations and respiratory arrhythmia. They have periods of 3 and 4 heart beats. Association of amplitude of 3-beats oscillation with level of mental readiness was shown due to further observation in two independent groups of 12 and 7. Moreover, possibility of assessment of mental readiness by the mathematical model based on heart rate periodogram was suggested.
