A. Tyka, T. Pałka, A. Tyka, T. Cisoń, Sz. Wiecha, A. Stawiarska, A. Cebulaaerobic threshold the recruitment of fast muscle fibres(IIx) begins to increase during incremental exercise [5,8, 10]. Furthermore, suggested rms-EMG method ofanaerobic threshold detection seems to be most easyto perform among other methods.There are some technical difficulties in the measurementof oxygen uptake and other respiratory indicesbecause the gas analyser and gas volumemeterare necessary, what is more the mask and valves withtube can constrict the movements. Blood lactate analysisneeds the very often sampling of blood being veryinconvenient for the subjects.Using the simple rms-EMG method for anaerobicthreshold determination one can evaluate the anaerobicthreshold very fast, during exercise test yet and supplythe results to the coach. The method is very convenientfor the subjects and easy to follow.ConclusionIn comparison to other methods of anaerobic thresholddetermination the rms-EMG curve analysis providethe results of the same accuracy but faster and in moreconvenient way.LITERATURE • PIŚMIENNICTWO[1] Helal JN, Guezennec CY, Goubel F: The aerobic-anaerobictransition: re-examination of the threshold concept includingan electromyographic approach.
