Experimental research regarding muscles activity

Abstract

The paper presents some experimental research regarding muscle activity using electromyography. The aim of this experimental study is to determine the biceps activity using non-invasive electrodes, during flexionextension movement of the forearm, as voluntary movements. These motions are caused by the isotonic contraction of the aforementioned muscle. We were able to identify the phases of the muscle activity, consisting of: the inactivity phase; the loading phase, the maintenance phase; the primary discharge phase; the motion stabilization phase, the secondary discharge phase and the inactivity phase.
