Figure 2. Group means and standard errors (N = 9) of activity/bite-force ratios for each muscle. Data next to the arrows indicate the factor by which the activity/bite-force ratio in chewing exceeded the activity/bite-force ratio in clenching. Since the bite-force cancels out, these factors also indicate the chewing/clenching ratios of the absolute activities. Abbreviations: mass = masseter, temp = temporalis, ws = working side, bs = balancing side.
