Research Method of Human Cardiovascular, Respiratory and Nervous Reaction Complex in Response to Dynamic Postural Loads

Physiological data on dynamic changes of human body posture in three-dimensional space is still under investigation, despite numerous studies in responses of human body to simple postural loads (PL). Research method of testing cardiovascular, respiratory and nervous reactions in humans in response to dynamic postural loads was introduced. Dynamic orientation of test subject in space was carried out using hardware-software complex for automatic postural changes (automatic turning table). Parameters of oscillatory motions were determined by corresponding software-controlled protocols. Simultaneous registration of signals and parameter was conducted by using electrocardiograph, reograph, tonometer for cardiovascular system; mass-spectrometer for respiratory system (to determine concentration of O2, CO2 and respiratory cycles); wireless electroencephalograph for central nervous system (brain). Study was performed on healthy volunteers. Examples of registered signals are presented. The results had shown, observed reactions on first swing correspond to predicted ones, however on second and third swings ambiguous complex changes occur and express shift in their direction and intensity.
