Physiologic changes of ECG parameters in actors during performance – reaction complexity

Abstract

The purpose of the study was to assess the dynamic characteristics of ECG parameters while performing different genre roles played by students of the Lithuanian Academy of Music and Theatre. Discriminant of the matrix was employed to assess the strength of the relation between a pair of two parameter sequences. The results of the conducted research showed that discriminant of regulatory and supplying systems decreased at different stages of the study process. In addition, the results revealed that the average discriminant values vary greatly only in the first stage – after isometric muscle relaxation ( p 0.05). No statistically significant differences were found for the rest of the stages (p 0.05).
