Comparative analysis of the psychophysiological parameters of the system quanta of performance in physically trained and untrained subjects

Abstract

Physiological mechanisms of muscle activity have been studied in 14 athletes and 15 untrained students during cyclic physical exercises of various intensities, including the individual maximum. The principle of system quantization of behavior has been used to find opposite changes in the spectra of the tachograms of athletes and physically untrained students after the completion of the same physical exercises. It has been shown that, after cyclic physical load in trained and untrained subjects, opposite changes in the effectiveness of their testing activity occur. © MAIK Nauka 2008.
