Gender differences have been studied by using spectral features and time features such as median frequency (MDF) and root mean square (RMS) in surface EMG signals during static exercise. MDF is the most commonly used as a feature to describe muscle conduction velocity. However, during dynamic exercise in daily life, the estimate of these features are difficult to indicate gender effects because of its instability and high standard deviation. The aim of this paper is to detect gender different characteristics from surface EMG signals during isotonic contractions as a dynamic exercise of the bicep Brachii. Eight volunteers (four females and four males) participated in this experiment to record surface EMG placed on the biceps brachii and each recording experiment continued until their endurance time. To find gender differences, we used feature values and regressive slopes of surface EMG and compared the feature changes from the onset to the endurance time of isotonic contractions. The result of experiments shows that the significant differences between males and females are not in the values of MDF and RMS (P>0.05) but in the slopes of them up to the endurance time (P<0.05). Therefore, the regressive slope of these features is valid to measure gender differences.
