Express 4 Power    Custom and Express Models
Performance mouthpieces for ALL SPORTS!

Testing performance attributes of the Express 4 Power for every sport is both desirable and possible.  Each sport has unique criteria to measure performance so a different program can be designed not only for every sport, but in many cases, position specific criteria within a sport.  The efficacy of the Express 4 Power can be tested on the equipment available at virtually any health club.

The following are general performance criteria common to all sports:
  • Posture
  • Blood oxygen
  • Carbon dioxide level
  • Strength
  • Speed
  • Range of motion
  • reflex time
  • Airway size
  • Heart rate variability
  • Visual perception

The staff at Express 4 Power will be happy to work with teams, athletic trainers, and other health professionals to design studies for performance evaluation.  Use the contact page if this is of interest.​
