• According to the WHO Constitution, "Health is a
state of complete physical, mental and social wellbeing and not merely the absence of disease or
infirmity“ (1946).
• Health is primarily a state of the organism, which is
characterized by the relation of structure and
function, as well as the ability of regulatory systems
to maintain a constant internal environment
(homeostasis). (Nikolay N. Zajko, Prof., Dr. Med.,
Soviet pathophysiologist, 1908-1991).
• The disease is a disruption of the normal functioning
of the body when exposed to damaging agents,
resulting in a decrease of its adaptive capabilities
(Nikolay N. Zajko).
• The disease is a dynamic state of an organism
characterized by disruption of normal flow of life
processes, resulting in reduced biological and social
abilities of a person.

• Proposed by Soviet scientists Roman M. Baevsky,
Vasily V. Parin and other (1966).
• Based on the analysis of subtle changes in the
temporal organization of control actions of the
nervous and endocrine systems on chronotropic
function of the sinus node of the heart.
• Assumes a three-level hierarchical model of heart
rhythm control.

Our body works according to the following rules:
• Normally, when the workload or everyday activity demands do not exceed
the capacity of CVS (e.g. rest or light intensity work), the heart is regulated
predominantly by autonomic level.
• When the workload becomes higher, the organism starts to involve
baroreflex level of regulation.
• When the workload becomes too high or external conditions become too
severe, the organism starts to involve sympathetic ergotropic and humoral
level.
• So, the higher intensity of work or adaptation, the higher level of
regulation is involved.
• Each higher level of regulation inhibits activity of lower levels.
• The state of stress is characterized by increased heart rate (HR), increased
sympathetic tone of ANS, increased blood pressure.
• State of relaxation is characterized by decrease of HR, increase of
parasympathetic tone (synonym – vagal tone) of ANS.
