Summary
The aim of the study was to follow muscular tissue electric activity after the application of whole-body cool therapy by means of surface EMG. The attention was devoted to the detection of MVC (maximum intentional contraction) before and after entering the cold chamber. Moreover, the authors followed the beginning of muscular fatigue in the course of isometric contraction before and after the application of whole-body cold therapy (CChT). Muscular activity was recorded from brachial m. biceps. Five top sportsmen at the age of 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 wehole-body cool therapy. In four of the five measured probands there was a delayed beginning of muscular fatigue after the application of CChT. Moreover, the application of CChT resulted in increased MVC in all five measured probands.
Key words:
whole-body cool therapy, cryotherapy, surface electromyography, muscular fatigue, isometric muscular contraction, maxima intentional muscular concentration (MVC)
