1. MONITORING THE FUNCTIONAL STATE OF AN INDIVIDUAL PRIOR TO ANY PROFESSIONAL ACTIVITY.
Typical targets of such monitoring are pilots, subway train operators, railroad engineers, nuclear power plant operators, air traffic controllers, military personnel, and athletes.

In order for the monitoring to be correct, it is necessary to establish an individual "norm" for each person by testing him or her with the Health-Express system three to five times on different days. The best result should be considered his "normal" Functional state. These tests will also show permissible deviations from an individual's norm. For example, the individual norm was defined as a score of 7.3 on the diagram in Figure 19. In this figure, the X-axis shows 13 gradations of the level of functioning of the physiological system, whereas the Y-axis shows seven levels of an individual's adaptation reserves, with the top level considered
The best. All the deviations from the individual normal state are shown as "." on the diagram, defining the range of possible functional states of an individual before the beginning of his working shift. A trained professional who knows the medical and psycho-emotional condition of the subjects should supervise (all tests).
All subsequent tests will monitor an individual functional state. Once the range of an individual's deviations from the norm is established, special attention should be paid to all scores that lie outside this range.
An example of a significant deviation from the norm, eight hours after the ingestion of alcoholic beverages, is shown in Figure 20 (before alcohol) and Figure 21 (after alcohol). Different factors, such as strong emotional stress, physical strain, infection, intoxication, and many others, both endogenic and exogenous, may cause this deviation.
In this case a trained professional is needed to define the cause and provide the test administrator with objective information.
2. MONITORING OF PERSONNEL TO REVEAL INDIVIDUAL FUNCTIONAL ABILITIES OR DYSFUNCTION

Fig. 22b
Fig. 23
This method helps to select individuals whose functional state places them in two opposite subareas on a diagram. (Fig. 23a, b).
The subarea (Fig. 22a) is determined by the significance of the adaptation reserves, because the problem of selecting individuals with great functional potential depends on such reserves. Slight, close to moderate and moderate reduction of the level of functioning (levels 5, 6, and 7) (Fig 23) is allowed in this subarea, as the state
Determined by point 1.1 is very rare and reflects not only physiological possibilities, but also a human psychoemotional state.
In a case when it is necessary to reveal individual distinctions (Fig. 22b) this subarea includes points that are possible only with subjects suffering from significant conditions that greatly reduce their functional state.
Among the factors or causes that place individuals into the subareas above may be following:
1. The so-called "acute state" which may be caused by different factors, among which the most typical are:
extreme overexertion;
psychoemotional stress;
rapidly developing infections and intoxication's
The acute states may be caused by some other factors too, but all of them create a roughly identical wave "portrait" of the HRV. An example of an acute state, caused by alcoholic intoxication, is shown on Figures 20, 21.
The Health-Express system is not a substitute for traditional functional diagnostics and laboratory examination methods, it complements them with qualitatively new integral information about the functional state of a human body.
3. OBJECTIFICATION OF DIFFERENT PHYSIOLOGICAL INFLUENCES.

Fig. 25a
Fig. 25b
The method of objectification is rather simple. Objectification entails the comparison of two test results: for example-before exercise or stress and after it. Two aspects are important in this case. First, the initial state (before exercise or stress) should be defined as an individual norm, as described above. Second, it is necessary to chose the proper time to test the subject post exercise or stress to find out duration of the subject's recovery to his/her norm. It is important that the post activity test should not be made during the recovery period, since it may distort the test results. A typical example might be the study of how sex influences the performance of an individual. In this case it is logical to conduct the test not right after intercourse, but the following day before normal activity.
