A motion mode determination apparatus is disclosed, including an inertial device, a frequency decomposition module, a characteristic value generator, a training module and a determination module. The inertial device collects at least a first motion signal corresponding to a first motion mode and at least a second motion signal corresponding to a second motion mode, wherein each of the first and second motion signals includes a first signal, a second signal and a third signal. The frequency decomposition module decomposes the first signal into a first high-frequency signal and a first low-frequency signal. The characteristic value generator generates a plurality of characteristic values, wherein the characteristic values are the means and variances for each group of the first high-frequency signals, the first low-frequency signals, the second signals and the third signals respectively. The training module generates first and second data groups. The determination module determines the motion mode of a third motion signal.
