NeuroGuard+ vs AIRWAAV: Performance, Protection, and What the Research Supports

Last updated

AIRWAAV is the leading performance mouthpiece — engineered around airway dynamics for endurance athletes. NeuroGuard+ is engineered for performance AND protection in one custom appliance. The performance research they both reference is real (9% airway width increase2, 8.4% respiratory rate reduction1, 5.8-14% performance improvements3). The protection research NG+ also engineers for is the 2023 BJSM meta-analysis showing custom mouthguards in collision sports are associated with a 26% reduction in concussion incidence5. Different design priorities, overlapping mechanism.

The core difference: design priority

Both products are custom-fit oral appliances built from dental impressions. Both target jaw and airway dynamics. The difference shows up in what each one optimizes for first:

  • AIRWAAV optimizes for airway opening and respiratory efficiency. The device's design priority is performance physiology — improving the breathing experience for endurance athletes (rowers, cyclists, runners, CrossFit). Brain protection is not in the engineering brief.
  • NeuroGuard+ optimizes for jaw position with airway dynamics as one of three protective mechanisms. The other two are force dissipation through posterior thickness (≥3 mm) and neuromuscular stabilization. Performance physiology comes along for the ride because the underlying research links jaw stabilization to both concussion-incidence reduction and airway/performance benefits.

The result: athletes in non-contact sports who only need performance can pick either product (and AIRWAAV's branding is more aligned with that use case). Athletes in contact or collision sports who need protection are in NG+ territory because the protective specifications AIRWAAV doesn't include — posterior thickness, retention under impact, jaw-stabilization design — are exactly what the concussion research requires.

The research both products reference

The performance research that supports the AIRWAAV category — and supports NG+ on the performance dimension — comes from a small-sample but methodologically rigorous body of literature on custom-fit oral appliances:

  • Garner & McDivitt 2009 (N=10, CT imaging): 9% increase in upper airway width during mouthpiece use (28.27 vs 25.93 mm, P=0.029); post-exercise lactate dropped from 2.72 to 1.86 mmol/L2
  • Garner & Lamira 2020 (N=17, randomized cross-over): 8.4% reduction in respiratory rate (28.35 → 25.97 BPM, p<0.01) and 5.3% reduction in minute ventilation during steady-state exercise1
  • Haughey & Fine 2020 (N=15 elite athletes): jaw-positioning custom mouthguard produced 5.8% lower-body power, 10% upper-body power, 14% hamstring flexibility, 4.8% balance improvements (all p<0.05)3
  • Caneppele 2017 meta-analysis (14 studies pooled): custom-made mouthguards do not significantly impair VO2max or VEmax (while boil-and-bite measurably does, p=0.0001)4

This is the same evidence base both AIRWAAV and NG+ point to. The samples are small in the individual studies (10, 17, 15) — the authors themselves call for replication — but the meta-analytic finding from Caneppele 2017 is the most generalizable. The defensible reading is that custom-fit oral appliances are associated with measurable airway and performance benefits relative to no mouthguard or to retail boil-and-bite alternatives.

The protection gap AIRWAAV doesn't address

AIRWAAV's marketing is consistent: it's a performance mouthpiece, not a concussion-protection device. That's actually FTC-aligned — they're not making concussion-prevention claims they can't support, which is the right move legally and editorially.

The gap is that not making concussion-protection claims also means not engineering for them. Specifically:

  • Posterior thickness: the 2014 Winters & DeMont RCT in HS football showed custom mouthguards averaging 3.5 mm posterior thickness produced a 3.6% concussion rate vs 8.3% for OTC mouthguards averaging 1.34 mm at injury (p=0.0423)6. AIRWAAV doesn't publish posterior thickness specifications because protection isn't the design target.
  • Jaw stabilization for impact: the 2023 BJSM meta-analysis of 192 studies found mouthguards in collision sports were associated with a 26% reduction in concussion incidence (IRR 0.74, 95% CI 0.64-0.89)5. The mechanism — jaw stabilization preventing condyle-to-skull-base force transmission — is a different design priority than airway opening.
  • Retention under contact: a performance mouthpiece worn during a rowing race or a CrossFit workout doesn't need the retention specifications a contact-sport mouthguard needs. NG+ engineers retention for hits, falls, talking under fatigue, and chewing/breathing through a long game.

For an athlete in a non-contact endurance sport, the protection gap is irrelevant — there's no protective scenario to address. For an athlete in football, hockey, lacrosse, rugby, wrestling, MMA, or boxing, that gap is the entire reason custom protective mouthguards exist as a category.

When each one is the right call

AIRWAAV is the right call when:

You're a non-contact endurance athlete — rower, cyclist, distance runner, CrossFit competitor — and your primary requirement is airway opening during exertion. You don't need posterior thickness or jaw-stabilization-for-impact specifications because there's no impact context. AIRWAAV's design priority matches your sport perfectly, and the performance research supports the use case.

NeuroGuard+ is the right call when:

You're in a contact or collision sport (football, hockey, lacrosse, rugby, wrestling, MMA, boxing, combat sports) and you need brain protection in addition to performance. The protective research that documents 26% concussion-incidence reduction in collision sports5 uses custom-fit jaw-stabilization-engineered mouthguards — which is what NG+ is. NG+ also delivers the performance benefits that AIRWAAV-class research describes, in the same appliance.

NG+ is also the right call for athletes who play multiple sports:

If your kid plays football in fall and runs track in spring, the NG+ device handles both contexts. The performance research applies in track; the protection research applies in football. One appliance, one fitting workflow, both seasons covered. Buying separate performance and protection mouthpieces for two seasons is a real expense most families don't need to take on.

What AIRWAAV gets right

This is a competitive comparison page, but it should be honest. AIRWAAV does several things right that we'd point any competitor to learn from:

  • FTC-compliant marketing. AIRWAAV doesn't claim to "prevent concussions" — they market the product for what the research actually supports (performance mouthpiece for endurance athletes). That's the right legal position and the right ethical position. The mouthguard-marketing category is full of brands that do worse on this dimension.
  • Custom-fit standard. AIRWAAV ships custom-fit oral appliances built from real dental impressions, not boil-and-bite. That puts them in the protective tier of the mouthguard category for the dimensions where they do address protection (e.g., dental injury reduction).
  • Cited research for performance claims. The studies AIRWAAV references in their marketing — Garner & McDivitt 2009, Garner & Lamira 2020 — are real peer-reviewed work that we cite on the same pages and reach the same defensible conclusions about. The performance category isn't fictional; it's grounded in research.
  • Sport-specific positioning. AIRWAAV markets primarily to rowing, CrossFit, and endurance sports — populations the research specifically applies to. They don't try to be everything for everyone.

Where NG+ differs is the protection dimension. We're engineered for it because we're built for athletes in collision contexts. Both products are honest about what they are; neither is a fraud, neither is over-claiming. The choice is design-priority alignment with the athlete's sport.

What we won't claim

NeuroGuard+ does not "prevent" concussions — even when comparing favorably against a competitor that doesn't make protection claims at all. We will never use the word "prevent" on this site. NG+ is associated with the mechanisms peer-reviewed research links to reduced concussion incidence in collision sports.

We also won't claim NG+ delivers "more performance than AIRWAAV" — both products draw from the same underlying research base on custom-fit oral appliances, and the small-sample studies don't support fine-grained product-vs-product comparisons on percentage performance gains. The honest framing is: both products are in the custom-fit oral appliance category; both reference the same evidence base; the design-priority difference is what actually distinguishes them, not raw performance numbers.

Marketing in this category responsibly means citing the same evidence honestly across the comparison and being clear about which dimension each product is engineered for.

Bottom line

AIRWAAV and NeuroGuard+ are both custom-fit oral appliances drawing from the same body of performance-physiology research123. AIRWAAV optimizes for airway dynamics in endurance sports. NG+ optimizes for jaw position with airway dynamics, force dissipation, and impact protection in one appliance. The performance benefit is shared; the protection benefit is the differentiator.

If your sport is non-contact endurance, AIRWAAV is in its element. If your sport is contact or collision, NG+ is the appliance the protection research56 keeps pointing back to. For multi-sport athletes, NG+ covers both contexts.

FAQs

Is AIRWAAV worth it?

AIRWAAV's performance research is real. The studies they cite — airway opening, respiratory efficiency, reduced post-exercise lactate — are legitimate research from peer-reviewed journals (Garner & McDivitt 2009 measured 9% airway width increase2; Garner & Lamira 2020 measured 8.4% respiratory rate reduction1). For a non-contact athlete focused purely on aerobic performance, AIRWAAV is a defensible choice. The gap is that AIRWAAV doesn't engineer for protection — so for athletes in contact or collision sports, the 2023 BJSM protection meta-analysis findings (26% concussion incidence reduction with custom mouthguards)5 aren't part of the value AIRWAAV is offering.

Does NG+ deliver the same performance effect as AIRWAAV?

The mechanism and the underlying research overlap substantially. The performance research AIRWAAV cites comes from studies on custom-fit oral appliances generally21. NG+ is also a custom-fit oral appliance designed around jaw position and airway dynamics. The 2017 Caneppele meta-analysis4 found custom-made mouthguards do not impair VO2max or VEmax (while boil-and-bite measurably do). The Haughey & Fine 2020 study3 of 15 elite athletes found jaw-positioning custom mouthguards produced 5.8-14% improvements across power and flexibility metrics. NG+ is engineered around the same biomechanical principles, with the addition of protective specifications AIRWAAV doesn't include.

Can I use AIRWAAV for football?

AIRWAAV markets primarily to non-contact endurance athletes (rowers, cyclists, runners, CrossFit). They don't position the device as a brain-protection product for collision sports, and the FTC enforcement environment around "concussion prevention" marketing claims has shaped that positioning. If you're shopping for football, lacrosse, hockey, rugby, wrestling, or combat sports, the relevant research is the protection research — the 2023 BJSM meta-analysis5 (192 studies, 26% concussion incidence reduction in collision sports), the 2014 Winters & DeMont RCT6 (custom mouthguards 3.6% concussion rate vs 8.3% for OTC). Custom-fit jaw-stabilization-engineered mouthguards like NG+ are what that research uses.

What's the actual difference in design between NG+ and AIRWAAV?

Both are custom-fit oral appliances built from dental impressions. AIRWAAV is engineered specifically around airway dynamics — the device's design centers on opening and stabilizing the upper airway during exertion. NG+ is engineered around jaw position with airway dynamics as one of three protective mechanisms (the others being force dissipation through posterior thickness and neuromuscular stabilization). Practically: NG+ has a posterior thickness specification (≥3 mm) the protection research keeps pointing to6, which AIRWAAV doesn't optimize for in the same way. The two product lines overlap in mechanism but differ in design priority.

Should I buy both?

No — you don't need two custom oral appliances. Both NG+ and AIRWAAV are designed to be worn for the duration of a competitive event. Athletes typically pick one based on the dominant requirement: if your sport is non-contact and your priority is endurance performance, AIRWAAV's positioning matches. If your sport is contact or collision and you need protection without giving up performance, NG+ is the appliance that engineers for both. The good news is that the performance and protection research point to the same biomechanical principle (custom-fit oral appliances stabilizing jaw and airway position), so the choice isn't between two unrelated products — it's between two design priorities.
