Measurement of EMG activity of muscular tissue after the application of whole-body cool therapy (-130°C)
Abstract
The aim of the study was to follow muscular tissue electric activity after the application of whole-cool therapy by means of surface EMG. The attention was devoted to the detection of MVC (maximum voluntary contraction) before and after entering the cold chamber.
Moreover, the autors followed the beginning of muscular fatigue in the course of isometric contraction before and after the application of whole-body cool therapy (CChT). Muscular activity was recorded from brachial m.biceps.
Five top sportsmen at the age 20-35 years participated in the measurement. Results of the study revealed that surface electromyography can detect changes in electric activity after the application of CChT.
Moreover, the application of CChT resulted in increased MVC in all five measured probands.
