Popis:	The purpose of this study is to evaluate physiological responses associated with exercise using two different mouthpieces compared with not using a mouthpiece. Improved performance while using the PX3 Bite Regulator (PX3) may significantly reduce the risk of concussions by allowing an athlete to better prepare, react, absorb, and/or avoid impact completely compared with the restricted breathing or mandibular instability that occurs when using mouthguards. Twenty-three subjects completed a battery of five physiological tests; the 1.5-mile run, sit and reach, anaerobic endurance, leg press, and bench press. Each test battery was completed under three conditions: wearing a PX3, wearing a mouthguard, or no mouthpiece respectfully. The PX3 resulted in significantly faster 1.5-mile run times (667.4 ± 9.4 vs. 684.9 ± 9.2 vs. 679 ± 7.9 s, p ≤ 0.05) and significantly longer anaerobic endurance runs (311 ± 23 vs. 283 ± 18 vs. 286 ± 18yds, p ≤ 0.05) compared with the mouthguard and no mouthpiece. The leg press lifts (51.8 ± 4.1 vs. 46.0 ± 4.3, p ≤ 0.05) while wearing the PX3 were significantly greater than when wearing a mouthguard. There were improvements, but no significant differences for sit and reach (16.8 ± 0.8 vs. 15.9 ± 0.8 vs. 16.4 ± 0.8 in., p = 0.73) and bench press (17.7 ± 1.8 vs. 17.2 ± 1.6 vs. 17.2 ± 1.7 lifts, p = 0.94). The increased performance with the PX3 could be a result of better jaw alignment and/or decreased resistance to airflow.
