Thermodynamic Method in Analyzing of the Parameters Bioelectrical Muscles at Different Static Loads

Abstract

The comparative analysis of the dynamics of changes in the bioelectric activity of muscles in
 response to changes in static stress in the muscle is presented. As the main result of this study after an data
 analysis obtained by the methods of the chaos theory and self‐organization to describe complex biological
 systems, it was established low efficiency of deterministic‐stochastic approach. Shannon entropy calculation
 is performed in different functional states of the muscles. Analysis of the recorded signal and evaluation of
 randomness in the recorded signal of electro‐myograms showed that with increasing load the size of quasiattractors
 of the recorded bioelectric potentials of the muscles increases dramatically, but the results of the
 analysis based on the calculation of the entropy, i.e. the thermodynamic approach, are statistically insignificant.
 The results allow to conclude that deterministic‐stochastic methods (in particular, the thermodynamic
 methods) in the assessment of electro‐myograms have low efficiency, and should be used for calculating the
 area quasi‐attractors of S in evaluating the physiological state of the human body (its homeostasis).
