Let the ArmourBite Mouth Guard by Under Armour help you be a better hockey player by reducing stress and fatigue, and increasing strength and reaction time. How does a mouth guard do all that? When you train and compete, your clenched jaw and teeth compress your temporomandibular joint (TMJ). This triggers your brain to release an excess amount of performance-sapping hormones that produce stress and fatigue. ArmourBite helps the human body help itself by pivoting your jaw down and forward, relieving pressure on the TMJ to unleash your full potential. There are many performance benefits that are included such as: increased strength due to improved airflow and less stress. Endurance will also improve because of those open airways. Better oxygen saturation also helps quicken your reaction time. Because of the Power Wedge that keeps you from clenching your jaw, you won't produce excess cortisol that causes stress and fatigue. It also reduces impact by 20% to lessen the severity of potential injuries.
