Muscle Fiber Conduction Velocity During Cycling Exercise

Muscle Fiber Conduction Velocity(MFCV) can be calculated from the time delay between the surface EMG signals recorded by electrodes aligned with the fiber direction. In Isometric and dynamic contraction, the property of the EMG signal is stationary and non-stationary respectively. The aim of this study is to validate the time delay estimators recently developed by our group. The proposed methods should be adapted the non-stationary of the data. These methods were analyzed by Monte-Carlo simulation to determinate their performance are sufficient in the practical condition. We test these estimators with the real data dynamics contractions in order to take into account the nonstationarity of the data. The results of this study also present the law of variation of MFCV during the cyclist circles.
