When it comes to performance running, most athletes focus on shoes, hydration, and training schedules—but few realize how much of a game-changer a performance mouthpiece can be. Whether you’re sprinting, running marathons, or incorporating jogging into your daily fitness routine, optimizing every aspect of your biomechanics and breathing can give you a massive edge. And here’s the surprising truth: your jaw plays a bigger role than you think. That’s where the New Age Performance 5DS Mid Profile Mouthpiece comes in—a performance-boosting, game-changing piece of gear every serious runner should know about.
This isn’t your average mouthguard. It’s not bulky, it’s not made for contact sports, and it’s not just about protecting your teeth. The 5DS Mid Profile Mouthpiece is made specifically for athletes looking to improve their physical performance. And unlike many thin mouthpieces on the market that compromise support for minimalism, New Age Performance proves that “Thin Does Not Win.” Let’s explore why.
The Role of Jaw Alignment in Running Performance
Why Jaw Stability Matters
Most people don’t associate the jaw with athletic performance—but the connection is real and powerful. When your jaw is misaligned, it creates tension through your entire body. This imbalance affects your posture, breathing, neck alignment, and even the way your core functions while you run.
Running requires proper posture, coordinated breathing, and minimal energy leaks. If your jaw is unstable or clenched, it can cause your upper body to tense up, reducing stride efficiency and increasing fatigue. On long runs, this inefficiency adds up. Over time, runners may experience decreased endurance, increased injury risk, and slower recovery.
A properly designed performance mouthpiece can stabilize the jaw, align the bite, and bring the head and spine into a more optimal position. This directly translates into better oxygen flow, reduced tension, and enhanced overall efficiency—all crucial factors in any runner’s training and performance.
Not All Mouthpieces Are Created Equal
There are dozens of “athletic” or “performance” mouthpieces out there, and many claim to boost performance. However, most of them fall short for a simple reason: they prioritize being as thin and unnoticeable as possible, often at the expense of real functionality.
Many of these ultra-thin mouthguards do little to properly stabilize the jaw or align the bite. They’re often marketed for convenience—something you can wear without feeling it. But when it comes to performance enhancement, thin is not enough. In fact, it’s often ineffective.
The New Age Performance 5DS Mid Profile Mouthpiece is designed to strike the perfect balance. It’s compact and comfortable enough for daily use, including running and cardio workouts—but with just enough structure to actually provide jaw stability and deliver measurable performance benefits.
What Makes the 5DS Mid Profile Mouthpiece Different?
1. Mid Profile Thickness That Actually Works
The 5DS Mid Profile is not too thin and not too bulky—it’s engineered to provide optimal jaw stabilization without interfering with breathing or comfort. It’s thicker than the ultra-minimal mouthpieces you might see marketed to runners, but that’s where the power lies.
That extra thickness provides enough material to position your lower jaw properly, align your bite, and support your body’s natural posture. It activates your temporomandibular joint (TMJ) in a way that helps eliminate unnecessary tension and helps you breathe easier.
2. Comfortable for Long Runs
Unlike heavy-duty mouthguards designed for contact sports, the 5DS Mid Profile is lightweight and ergonomically designed. You won’t feel like you’re wearing something bulky or intrusive. It fits snugly and securely in your mouth, allowing for unrestricted breathing—an essential feature for any runner.
Whether you’re doing a quick 5K or a grueling long-distance trail run, the 5DS Mid Profile stays in place without shifting or becoming uncomfortable. It’s sweat-resistant, easy to clean, and designed with endurance in mind.
3. Real Biomechanical Benefits
This isn’t hype—it’s science. New Age Performance mouthpieces have been tested across multiple sports and have consistently shown to help improve posture, strength output, oxygen efficiency, and reduce the risk of injury. For runners, these benefits translate into:
-
Improved breathing capacity
-
Reduced upper body tension
-
Better spinal alignment
-
Enhanced stride efficiency
-
Increased endurance
You’ll feel the difference not just during runs, but also in recovery and how your body responds to prolonged activity.
“Thin Does Not Win”: Why Runners Need More Than a Minimal Mouthpiece
Misconception: Runners Don’t Need Mouthpieces
Many runners assume that because they aren’t getting hit in the face, they don’t need a mouthguard or mouthpiece. But the truth is, the benefits of a performance mouthpiece go far beyond protection. Jaw position influences breathing, posture, energy output, and neurological activation. A proper mouthpiece is not just about protection—it’s about performance optimization.
The Thin Trap
Ultra-thin mouthguards are appealing because they seem convenient. But they often lack structure, durability, and function. When a mouthpiece is too thin, it simply doesn’t provide the stabilization necessary to engage your core properly, improve your oxygen intake, or keep your posture aligned during your run.
Wearing a thin, ineffective mouthpiece is like wearing flip-flops to a marathon. Sure, they’re light and easy—but they’re not built for performance. The New Age 5DS Mid Profile was designed specifically to avoid this pitfall, giving you a serious edge without compromising comfort.
Real-World Feedback: Runners Love the 5DS Mid Profile
Runners of all levels—from casual weekend joggers to elite marathoners—have shared glowing reviews of the 5DS Mid Profile mouthpiece. Here’s what they consistently report:
-
“I can breathe better during long runs.”
-
“My shoulders and neck feel less tight after a run.”
-
“I recover faster and feel less fatigue.”
-
“It helps me maintain better form even at the end of a long race.”
In short, runners are finding the same benefits that powerlifters, HIIT athletes, and MMA fighters have known for years: jaw stability matters, and New Age Performance has cracked the code.
The Science of Jaw Alignment and Performance
TMJ and Athletic Performance
Your temporomandibular joint (TMJ) is more than just where your jaw hinges—it’s directly linked to your posture and neuromuscular system. Misalignment can lead to tight shoulders, poor spinal alignment, and compromised breathing.
By stabilizing your TMJ with the 5DS Mid Profile mouthpiece, you’re essentially tuning your body into its most optimal form. It allows your nervous system to engage the right muscles, keep your head in the proper position, and maximize oxygen intake, especially during high-effort runs.
Oxygen and Endurance
Breathing efficiency is everything in running. When you’re gasping for air or breathing shallowly, your performance dips. The right mouthpiece can help open up your airway and relax your neck and shoulder muscles, making it easier to take deep, rhythmic breaths.
This is especially important during tempo runs, intervals, and distance work—when every breath counts. With better breathing comes increased stamina, more consistent pacing, and a smoother stride.
When to Use the 5DS Mid Profile for Running
One of the best things about the 5DS Mid Profile mouthpiece is its versatility. It’s designed for daily wear during any athletic activity, but it particularly shines in:
-
Long-distance running
-
Tempo and interval training
-
Treadmill sessions
-
Trail and mountain running
-
Obstacle races (like Spartan or Tough Mudder)
-
Recovery jogs and active recovery days
It’s easy to wear, quick to clean, and compact enough to keep in your gym bag or pocket.
How to Use and Maintain It
Getting started is simple:
-
Fit It: The 5DS Mid Profile uses a boil-and-bite method for custom fitting. Just follow the instructions provided for a secure fit that’s personalized to your bite.
-
Use It Regularly: Wear it during runs and cardio sessions consistently to feel the long-term benefits.
-
Clean It: Rinse with cold water after each use. For deeper cleaning, use a toothbrush and mild soap or a mouthguard cleaner.
It’s built to last, so with regular maintenance, one mouthpiece can support months of daily runs.
Final Thoughts: The Clear Choice for Runners
In a world full of flashy gear and quick fixes, it’s refreshing to find a product that delivers real, measurable results. The New Age Performance 5DS Mid Profile Mouthpiece isn’t just another gimmick—it’s a performance tool that taps into biomechanics, breathing, and alignment to help you run smarter, harder, and longer.
