The regulatory-adaptive state and evaluation of stress resistance in humans

The method of estimating human stress resistance by the dynamics of the regulatory-adaptive state is described. The regulatory-adaptive state has been evaluated by the parameters of cardio-respiratory synchronism in the normal state and in stress. Subjects with no changes in the regulatory-adaptive state or with its decrease by 5–6% have been included in the group with a high level of stress resistance. Subjects with a decrease of the regulatory-adaptive state by more than 50% in response to stress have been included in the low stress resistance group. The method has been tested in three models of stress: (1) examination (58 students); (2) parachute jumping (35 beginner parachute jumpers); (3) entrance to an emergency zone (30 rescuers). All three models are highly informative. Stress resistance levels have also been estimated by psycho-logical methods. The estimation of stress resistance by the dynamics of the regulatory-adaptive state allows characterizing the ability of a person to endure stress and can be included in the set of tests for staff recruitment in extreme professions.
