Abstract: Objective. The objective of this study was to compare these methods Fourier (STFT) and Wavelet (WT) transforms to assess muscle fatigue during supramaximal exercise. Methods. Twenty five subjects of both genders (13 men, age = 28.2 ± 2.7 years and 12 women, age = 23.2 ± 2.7 years) performed the Wingate test, during which the electromyographic responses of the superficial muscles of the quadriceps were examined. For analysis we used the STFT and WT transforms, which provided the following variables: median frequency (MF), slope and variance. Results. The results showed no differences (P > 0.05) in MF and slope. However, there were differences for the variance between the analysis (P < 0.05). Conclusion. It seems that both analyzes provide the same physiological parameters, however, the WT transform shows less variance between the results. © 2012 Revista Andaluza de Medicina del Deporte.
