Maximum amplitude and harmonic ratios of the sacrum positions of each subject in y-axis. The left figure shows the maximum amplitudes of the subjects’ sacrum at the frequencies of the trials, and the right one shows their harmonic ratio in y-axis (frontal direction). The maximum amplitudes of the two subjects decreased. On the other hand, the harmonic ratio of one subject slightly increased
