In sport, it is well known that mental preparation to a physical effort increases drastically the performance. In this paper, we present a study that aims to evaluate the effect of movement preparation during pre-motor activity on the EMG signal. We considered the existence/no-existence of preparation and preparation duration as indicators. The results of this study performed on different muscles of the forearm show : i) Female are sensitive to preparation warning whereas male are not sensitive, ii) Contrary to deep muscles, superficial muscles are affected by preparation warning.
