PRINCIPLES OF HOMEOSTATIC REGULATION OF FUNCTIONS IN HUMAN ECOLOGY

The founder of the homeostasis theory W. B. Cannon spoke about the lack of stability of homeostasis and systems of homeostatic regulation. However, to date, the postulate of the statistical stability of samples of homeostasis parameters in various functional systems has been working in human ecology. The aim of the study is to verify this fundamental postulate and to prove the lack of statistical stability of samples of the neuromuscular and cardiovascular systems. Methods: age-related dynamics of cardio intervals was studied in three groups (38 people in each group) of Khanty women and three groups of newcomers (228 people in total), tremor and tapping parameters were studied in two groups: women (18 people) and men (16 people). The Elox-01 device was used to record cardio intervals, and the patented tremograph was used to record tremorograms. Results: the absence of statistical stability of tremorograms was proved (the number of samples of k pairs that have one sampled population not more than k1 < 5 % for tremor and k2 < 12 % for tapping), for cardio intervals k3 < 17 %. The samples are not homogeneous, the probability of their statistical repeating in a row is p < 0.05 (for one subject in constant homeostasis). It is proposed to calculate the parameters of quasi attractors that really demonstrate statistical stability (in constant homeostasis). Conclusion: the samples of the parameters of neuromuscular and cardiovascular systems are not statistically homogeneous (they change chaotically). In this regard, to assess the norm (standard) of homeostasis, it is advisable to use the calculation of the parameters of quasi attractors along the first coordinate x1 (for example, the parameters of cardio intervals or tremorograms) and x2 (rate of change x1).
