[Evolution of methodical approaches to solve problem of evaluating and predicting the thermal status of cosmonauts in the real flight]. / Evoliutsiia metodicheskikh podkhodov k resheniiu problemy otsenki i prognozirovaniia teplovogo sostoianiia kosmonavta v real'nom polete.

The problem of evaluating and predicting the thermal status of a cosmonaut in the long-term space mission is a pressing one and remains to be solved. The previous studies indicated that the best plan to be followed is to evaluate the thermal status of a cosmonaut during his egress into outer space with the use of the procedure of parotid thermometry of the mean body temperature.

[The physiological classification of human thermal states under high environmental temperatures]. / Fiziologicheskaia klassifikatsiia teplovykh sostoianii cheloveka v usloviiakh vysokikh temperatur okruzhaiushchei sredy.

The paper deals with the physiological classification of human thermal states in a hot environment. A review of the basic systems of classifications of thermal states is given, their main drawbacks are discussed. On the basis of human functional state research in a broad range of environmental temperatures the system of evaluation and classification of human thermal states is proposed. New integral one-dimensional multi-parametric criteria for evaluation are used. For the development of these criteria methods of factor, cluster and canonical correlation analyses are applied. Stochastic nomograms capable of identification of human thermal state for different intensity of influence are given. In this case evaluation of intensity is estimated according to one-dimensional criteria taking into account environmental temperature, physical load and time of man's staying in overheating conditions.

[Hemo- and neurodynamics of the human brain during exposure to moderate hypoxic hypoxia]. / Gemo- i neirodinamika golovnogo mozga cheloveka pri vozdeistvii umerennoi gipoksicheskoi gipoksii.

Synchronous electro- and rheoencephalography were used to study tolerance to moderate hypoxic hypoxia for 30 min at an altitude of 5000 m without additional oxygen supply. As test subject, men with autonomic-vascular dystonia (29-39 years old), 15 men over 40 (41-56 years old), and 16 essentially healthy controls (23-36 years old) were used. The aged volunteers (41-56 years old) did not differ from the controls with respect to their tolerance to hypoxic hypoxia. The men with early symptoms of hypertonic-type dystonia also showed high tolerance to hypoxic hypoxia. The subjects with hypotonic-type dystonia displayed lower tolerance.
