Seven normal male and seven normal female volunteers performed three types of biting exercises: an intermittent contraction at maximum voluntary bite force (MVBF) to pain intolerance; a ramp intermittent contraction starting at 10% MVBF and increasing 10% every 10 s; and a sustained biting at 100% MVBF to pain intolerance. The following measurements were made on the first and second days before exercise: a pre‐ and post‐exertional overall jaw pain level; maximum pain‐free jaw opening; bilateral masseter pressure pain threshold (PPT) and intolerance (PPI). The results showed that only females presented an increased overall pain level on the second day and a significant decrease in pain‐free jaw opening, but no significant decrease of PPT and PPI. These results suggest that females respond differently than males to exertional jaw pain, by increasing their pain response 24 h later.
