A new model of discriminant analysis for assessing the dynamics of human body adaptation to different living conditions

Abstract

Based on the data of registration of heart rate variability and blood pressure indicators, a discriminant analysis model has been developed that allows visualization of the conditional values of “functional reserves of the body“, and “the degree of stress of regulatory systems” on the phase plane. The model includes: heart rate, systolic blood pressure, relative power of the HF range of the heart rate variability spectrum, pNN50. The presented illustrations allow us to consider that this new model is sufficiently sensitive, representative, and has the potential for use by other research groups working with healthy people, in particular, in monitoring projects and in the field of environmental physiology.
