The subjective fatigue was assessed in Borg’s RPE, the pain intensity in numeric rating scale (NRS), the pain area in arbitrary units (au), the pressure pain threshold in kilo Pascal (kPa), the maximum voluntary bite force in kilogram (kg) and the maximum voluntary mouth opening capacity in millimeters (mm). Data are expressed in median (IQR; interquartile range). P-values refer to the comparisons between trials by Wilcoxon Signed Rank and sexes by Mann-Whitney Rank Sum test. * = significant difference P < 0.005 for subjective fatigue and pain intensity, < 0.013 for pain area after applied Bonferroni Corrections and < 0.05 for the rest of the variables
