The subjective fatigue was assessed in Borg’s RPE, the pain intensity (=peak pain) in numeric rating scale (NRS), the pain area in arbitrary units (au), the change in pressure pain threshold in percent (%), the change in maximum voluntary bite force in percent (%) and the change in maximum voluntary mouth opening capacity in percent (%). Data are expressed as median (IQR; interquartile range). P-values refer to the comparisons to baseline data by Friedman’s analysis of variance for repeated measures with Tukey post-hoc test. * = significant difference P < 0.05. #End refers to end of chewing
