Mean Slope (a1) of MF Evolution. The MF evolution mean slope (a1) is shown for the both muscles (Biceps & Brachioradialis) and for the both signals (SEMG and MMG) for the groups of Women, Men and Total (see legend). In all the cases the MF slope is negative (MF decreases in time), showing the compression of PSD toward lower frequencies. The standard deviations are shown.
