    "abstract": "In order to assess fatigue independent amplitude-frequency correlations in\nEMG signals we asked nineteen male subjects to perform a series of isometric\nmuscular contractions by extensors of the knee joint. Different amplitudes of\nthe signal were due to randomly varying both the joint moment and the overall\namplification factor of the EMG apparatus. Mean and median frequency, RMS and\nmean absolute value were calculated for every combination of joint moment and\namplification at the original sampling rate of 5 kHz and at several simulated\nlower sampling rates. Negative Spearman and Kendall amplitude-frequency\ncorrelation coefficients were found, and they were more pronounced at high\nsampling rates.",
