Traditional clinical medicine fights disease: even if you feel unwell, but there are no obvious pathological symptoms, the clinic doctor will consider you healthy. Engy Health is based on a fundamentally different approach that is used in sports, industrial and space medicine.
You are healthy if you are able to effectively and effectively adapt to changing, often stressful, external and internal conditions. And at the same time functional reserves are sufficient to maintain homeostasis , that is, the integrity of the body's systems.
Health components can be in different training states. And therefore, a special space is distinguished between health and illness - pre-painful, or "prenosological" , conditions. Engy Health records the imperceptible transition from health to pathology and notifies you about it.
You take action on time and return to a state of health when the body itself is already successfully resisting diseases.
The ability of the body to maintain its own integrity and balance, to adapt to stress is homeostasis. This balance, though constant, is dynamic. And our regulatory systems interact continuously to keep the body in a state of health.
The property of the body to adapt to changing circumstances. It is a state where the processes of relaxation and tension are in balance, when the body easily tenses to do work and easily relaxes for good rest in order to accumulate energy for subsequent tasks.
In a state of relative rest, a person practically does not need to spend energy. But as soon as a task appears, work begins. To solve it and maintain its balance, the body uses functional reserves. These include physiological, biochemical and psychological.
Physiological reserves are the ability of organs and organ systems to change their activity for the optimal functioning of the body at the moment. Biochemical reserves are the possibilities of accelerating or increasing the volume of biochemical processes. Mental reserves are the capabilities of the psyche: the ability to concentrate, increase motivation, withstand emotional stress, control behavior, etc. Simply put, functional reserves are the range of the body's capabilities, changes in the activity of its mechanisms in order to adapt to stress factors.
The disease does not arise from scratch. Studying the well-being of astronauts before and during flights, scientists noticed that between health and illness, a number of body conditions can be identified, which reflect the degree of readiness to adapt and use their functional reserves:
Adaptation to external factors is unsatisfactory, and functionality is reduced. Homeostasis is preserved due to significant tension of regulatory systems or the inclusion of additional compensatory mechanisms.
To maintain health, such conditions already require the mobilization of functional resources, that is, the tension of regulatory systems. The body's adaptive capabilities have not yet been reduced, but the ability to adapt to stress is reduced. Homeostasis is maintained only through additional tension.
This condition is characterized by a sharp decrease in the functional capabilities of the body. Homeostasis is impaired and pathological changes begin to develop at the systemic level. In other words, a person gets sick.
This classification of health conditions is the basis of the Baevsky diagram, a key element of the Engy Health application.
It is characterized by satisfactory adaptation of the organism to the environment. This means that you have enough functionality to overcome stress and overload. Homeostasis is maintained at a minimum voltage of regulatory systems.
How to measure health status and transition to borderline prenosological states? The answer was given by scientists: the heart. The heartbeat is the Morse code of the body. The heart is a unique organ with its own autonomous conducting system and the only one whose work we ourselves hear.
Through the work of the heart, you can assess the state of the whole organism. The analysis of heart rate variability (HRV) will help with this. HRV allows one to study the mechanisms of regulation through the ability of the heart to effectively accelerate or decelerate. At the same time, we receive invaluable information for a comprehensive health diagnosis.
03.1 Levels of regulationHere is an interactive diagram of the interaction of external and automatic regulation loops. Hover over an item or arrow to learn more about it,
Pulse is the heart rate per minute. It shows the current level of functioning of the cardiovascular system. An increase in heart rate from 90 to 150-180 beats per minute in healthy people occurs during physical and emotional stress and is called sinus tachycardia.
A decrease in the pulse rate to 59-40 with the correct sinus rhythm is called sinus bradycardia. Among healthy people, it is often seen in athletes. The mathematical analysis of the pulse makes it possible to translate biological processes into the language of numbers and mathematics. At the same time, within the framework of the scientific approach to the analysis of heart rate variability, the following methods are used:
Based on the measurement of RR-intervals (time between two consecutive heartbeats) and NN-intervals (intervals only between normal contractions, excluding interference and arrhythmias), their comparison and obtaining a quantitative assessment of variability. Engy Health uses statistical analysis to determine the Stress score
standard deviation of all NN intervals. It reflects all periodic components of variability during the recording, that is, it is the total HRV indicator.
evaluation data comparing NN-intervals.
the ratio of NN slots that differ from each other by more than 50 ms, with a total of NN slots.
corresponds to the number of RR-intervals that occur most often, therefore, they allow to assess the real state of the patient's regulation systems.
shows the proportion of those intervals that correspond to the value of the mode in the total number of intervals for a certain period of time. This parameter reflects the stabilizing effect of centralizing heart rate control.
corresponds to the difference between the duration of the largest and smallest intervals.
Allows you to quantify the impact on the heart of various regulatory systems . According to the results of the application of the Fourier analysis, several components are distinguished that correspond to fluctuations in the heart rate of different frequency:
The HF component is associated with respiratory movements and reflects the influence of the vagus nerve on the heart, that is, the parasympathetic nervous system. Fluctuations in its activity give rise to changes in the heart rate with a frequency (0.150.4, Hz) and more, forming fast waves (HF - high frequency).
The LF component shows mainly the effect on the heart rate of the sympathetic nervous system and the oscillations caused by it (0.04 - 0.15, Hz), they are called slow waves (LF - low frequency).
VLF-components belong to the slowest system of regulation, humoral-metabolic. It produces very low frequency (VLF) waves corresponding to frequencies less than 0.04 Hz.
This indicator reflects the action of various factors, which include, for example, vascular tone, thermoregulatory system, humoral tone and the influence of the central nervous system.
Further mathematical analysis of LF, HF and VLF waves allows you to build a spectrogram. The abscissa shows the frequency of the waves in Hertz, and the ordinate shows the power in milliseconds squared. It is also convenient to visualize the data of the influence of various regulatory systems through the pie chart of the spectral power of the ranges.
Engy Health service uses a nonlinear dynamic method to determine the Load indicator (PARS)
The technique was developed by the Institute of Biomedical Problems of the Russian Academy of Sciences to monitor the health of astronauts, and later received a worldwide vocation in sports and industrial medicine. Thanks to the mathematical methods of pulse analysis, you can measure the following indicators of your health:
Energy (Total Power) reflects the readiness of the heart to flexibly change its rhythm, responding to situations that arise under the influence of signals from regulatory systems (parasympathetic system - relaxation, sympathetic system - tension and the centralized regulatory system - humoral system / CNS). The more optimal this indicator, the healthier and more vital you are. The further from it, the closer you are to the possibility of illness.
Physiological significance:
Energy or Total Power - the total power of the frequency spectrum of the cardiac intervalogram after the Fourier transform, it reflects the degree of impact on the heart rate of all levels of regulation.
The volume of work of the heart to adapt to external changes is calculated mathematically. Since this process is provided by 3 regulatory systems, respectively, three parts of the TR indicator are distinguished: HF, LF, VLF.
How is it considered
TP is calculated by spectral analysis of R-R intervals using the formula:
TP=VLF+LF+HF

PARS - Indicator of the Activity of Regulatory Systems - reflects the degree of stress and the amount of body resources that are necessary to maintain health. This is the price that the body must pay for its own recovery, that is, to return to the state of homeostasis.
Physiological significance:
PARS is a complex, integral indicator characterizing the complex activity of regulatory systems (parasympathetic system - relaxation, sympathetic system, humoral system and central nervous system - 3 levels of stress). Each level of tension corresponds to a certain state of the organism's adaptive capabilities and is measured in points. The more points it shows, the more resources the body must spend on recovery and the longer it will take.
PARS is calculated according to the formula:
Level of functioning + Stability of regulation + Vegetative homeostasis + Activity of the sympathetic vascular center + Degree of centralization of control

The Stress metric reflects how much you strain in response to stressors now. Basically, it characterizes the activity of the sympathetic division of the autonomic nervous system, which is responsible for reaction and mobilization under stress. This indicator is very sensitive to any, even minor, physical and psychological stress.
Physiological rationale:
Stress is the body's nonspecific response to any problem and consists in the nonspecific need to adapt and restore homeostasis.
Stress level is the degree of physical and psychological stress in response to the sum of stressors at a given time.
How is it counted?
АМо /(2 * Mо* MxDMn), where
Амо (mode amplitude) is the number of cardiointervals corresponding to the mode value, in% of the sample size.
Мо (mod) is the most frequent value of the cardiointerval in this dynamic range, in seconds
MxDMn (variation range) in sec. reflects the degree of variability of values of cardiointervals in the investigated dynamic series. It is calculated by the difference of the maximum (Mx) and minimum(Mn)

Pulse is the number of heartbeats per minute. Varies depending on the degree of wakefulness. Drops to 45-50 strokes during sleep, rises to 180 during significant exertion.
How it is calculated:
The pulse is calculated by the formula:
60 * 1000 * (n/m), где
n - number of NN intervals in the record
m - duration of recording NN intervals
NN-intervals - the intervals between the normal contractions of the heart.

The indicator reflects the balance of the divisions of the autonomic nervous system: sympathetic (responsible for tension) and parasympathetic (responsible for relaxation). You can see which of the processes - tension or relaxation - prevails at the moment. Balance is one of the most reliable predictors of life expectancy. Can be improved through training.
Physiological significance
Vegetative balance (LF / HF) is the ratio of low frequency (LF) wave power to high frequency (HF) wave power. It is used as an index of parasympathetic and sympathetic balance, which is an estimate of stress at a given point in time.

HR - heart rate
SBP - systolic blood pressure
DBP - diastolic blood pressure
Age - age, years

Stress as such cannot be considered harmful in itself: it is necessary to increase the tone of life. However, frequent stressful situations and negative emotional influences disrupt the normal activity of the cerebral cortex and centers of the hypothalamic region. The weakening of control on the part of the cerebral cortex leads to a significant increase in the excitability of the vasomotor center and, consequently, to a violation of the vascular tone. HRV methods through assessing the state of the sympathetic nervous system and the balance of the autonomic nervous system allow you to identify the level of stress and control it.
