Mouthpiece for Weight Training?

Posted by Evan Perperis on January 10, 2015 at 7:15 AM

 

I consider my approach to training grounded and backed by science. This article from the Wired is one of the many I have read that say having a mouthpiece in and clenching your teeth while lifting reduces cortisol levels. Cortisol is a stress hormone, so lower cortisol will result in better muscle growth.

I decided to buy the Under Armour mouth guard as a test. Initially it felt a little weird breathing through the mouth guard and having something in your mouth while training. However, now I love it. Clenching during heavy movements (squats, leg press and deadlifts especially) just feels right. UA’s is also low profile enough where you do not make a scene with something big and bulky in your mouth. The mouth guard still allows you to speak normally and (based on science) should improve lifting.

When training I follow an approach that I learned from cycling. With cycling, they try to improve every aspect of every part of their bikes and bodies. The idea is if you make enough changes that result in fractions of a percentage of improvement, the combination of all these changes will be a measurable improvement. If you think buying this product will immediately add 50 lbs. to your deadlift, you are wrong. However, I did feel like I could lift a couple of more pounds while wearing the mouth guard. Whether it was a placebo effect or actual improvement, I am not sure. The bottom line is, I feel like I can lift more when clenching my teeth. This does not even take into account the true value of the guard, which is lower cortisol levels, something that requires lab equipment to measure. If you are committed to maximizing your potential, this is a good product for you.
