Figure 2

The figure describes the activity monitor output as a function of the frequency at both short radius (22 mm) of oscillation (A) and long radius (49 mm) of oscillation (B), with the Low Frequency Extension (LFE) option disabled. Frequency is expressed as s-1 and the average acceleration in ms-2. The results are presented as means and the standard error of the mean (SEM). The scales differ between radii of oscillation.
