Abstract—In this study, determination of fatigue at the onset, and following maximal loaded exercise was evaluated from mechanomyography (MMG) and electromyography (EMG) recordings in exercise trained men. Twenty four recreationally active men were participated into this study. Participants were performed a fatiguing Bruce Protocol which is widely-used maximal loading treadmill test. EMG and MMG recordings were obtained from rectus femoris muscle during maximal isometric contractions both at the onset, and following Bruce Protocol. Following pre-training measurements, volunteers were subjected to sprint running exercise involved 3 sessions per week for 8 weeks. MMG and EMG recordings were repeated following 8 weeks of sprint running training. Recordings were decomposed in 8 levels by using the wavelet packet transform and so windows with 15 nodes and 5 sliding nodes were created. Then the mean energy values at each window were obtained from the 24 persons group and were applied to the input of Multilayer Perceptron Neural Network (MLPNN). In the output, the classification process was performed both before and after fatiguing exercise, and the success rate of the test was evaluated for fatigue. In the post-training measurements, MMG has been failed to determine fatigue with decreased success rate, whereas EMG results were shown that success rate is increased by 20 percent compared to pre-training measurements.

Index Terms—Electromyogram (EMG), fatigue, mechanomyogram (MMG), wavelet packet transform.
