What these videos show is that:

     1. The mouthguard as the only variable in the exercises is all that alters                  the athlete's ability to facilitate better these exercises.

      2. The mouthguard as the only variable in the exercises is all that is                      changing the skeletal and muscular physiology of the athlete.

      3.  If you are an athlete wearing a mouthguard or a mouthpiece during competition and it does not allow you to reproduce these changes you see in strength, breathing, flexibilty and balance, then you should at least reconsider getting a new mouthguard/mouthpiece. You may need a new "TOOL" for your "TOOLBOX".
