[Various subjective and objective indicators of intellectual and emotional stress in air traffic controllers during different work shifts].

The purpose of the study was to examine air-traffic controllers attending the automated air-traffic management system called Start. The data revealed that during the night shift air-traffic controllers experienced significant changes in body functioning in comparison with morning and day shifts (deterioration of self-appraisal indices and elevation of catecholamin excretion). The correlation analysis demonstrated that activation of sympathoardrenal chains (primarily of the mediator chain) had a negative influence on the indices of health state, activity and attitude of mind of air-traffic controllers.

[The hemodynamics and activity of the sympathetic-adrenal system in air traffic controllers during their professional duties].

A functional status of the circulation and catecholamines excretion in air traffic controllers operating in two shifts (morning and daytime duties) and attending a Start air traffic control system have been assessed. It is shown that a correlations pattern between parameters under study is significantly altered depending on an occupational activity time. The dependence of hemodynamic shifts on an activity of hormonal and mediator components of sympathetic-adrenal system, an accomplishment of the catecholamine effects on cardiovascular activity with an involvement of alpha- and beta-adrenoreceptor system are shown.

[Effects of shift work of air traffic controllers on several parameters of the activity of the sympathetic-adrenal system].

Using a Start air traffic control system, sympathetic-adrenal parameters were measured in air controllers who worked in the morning, afternoon or night shifts. The highest catecholamine excretion was detected in air traffic controllers, who worked at night-time with a low workload Night-time work led to a stress reaction in a larger number of air controllers. In every shift a certain number of air controllers showed a decrease of catecholamine excretion, which can be viewed as a manifestation of sympathetic-adrenal inadequacy and a failure of adaptation mechanisms. The paper gives a detailed description of correlations between epinephrine, norepinephrine, dopamine and DOPA excretion.

[Biochemical indices of emotional stress in air traffic controllers].

Air traffic controllers working in automatic and nonautomatic stations showed high values of lipid metabolism parameters as well as significant activation of the sympathoadrenal system (especially, its hormonal component). The level of the parameters under study was correlated with the workload.

[Biochemical and psychological indicators in air controllers in the "pre-start" state before beginning work activities].

The biochemical parameters (renal excretion of catecholamines, lipid metabolism, cholinesterase activity in blood, excretion of sodium and potassium in the saliva) and psychological parameters (attention concentration, anxiety, rate of information processing) of air controllers were determined immediately before their work shift. Most of the parameters were significantly changed.
