OptiO2 Labs is a local company based out of Nashville, that has recently unveiled the world’s first line of performance enhancing mouthpieces designed to promote optimal breathing technique.

Among many others, owners Jake Shuler and Austin Mallette believe breathing through the nose can be critical to basic health. Along with reducing stress, increasing focus and regulating blood pressure and body temperature, using the nose to breathe has been shown to delay muscle fatigue, slow the effects of dehydration and reduce lactic acid build up in the muscles. These benefits only scratch the surface of what studies have continued to uncover.

Jake and Austin both grew up playing sports and have a passion for training at a high level as well as understanding how the human body can increase its potential. While he was in school, Jake studied Exercise Science and worked in the Tennessee Volunteer football weight room as an Assistant Strength Coach where he learned a number of different training techniques that he still utilizes today.

Even though the human body was designed to use the nostrils as the primary means of breathing and filter the air we breathe, it can be tough to maintain proper technique, especially under physical stress and exertion.

“For athletes, nasal breathing helps develop aerobic capacity and can also keep us in check with our technical or mechanical limitations. We can always get away with going faster or harder with breathing predominantly through our mouths, but breathing through our nose encourages us to focus on efficiency and forces us into a biomechanically optimal position to access our diaphragm and a full breath,” says Brian MacKenzie of Power Speed Endurance.

“After discovering the performance and recovery benefits of nasal breathing, I looked for something that would remove the option of mouth breathing. I couldn’t find anything, so I got together with Austin to brainstorm and the result was the OptiO2 Sport,” Jake explains.

The OptiO2 Sport mouthpiece (shown in the diagram) is designed to help athletes breathe better, train harder and recover faster. The lightweight piece resembles a traditional mouth guard with an added shelf that slides under and elevates the tongue, which fully opens the nasal airway. The device also features an ergonomically shaped front wall that serves to prevent any airflow into or out of the mouth. By eliminating the ability to breathe through the mouth, an athlete’s body can intake the proper amount of oxygen through the nostrils.

The OptiO2 Sport also features a bite pad that encourages an aligned jaw while protecting the teeth. Training with a bite pad and proper jaw alignment helps to open airways and has been shown to enhance posture, increase strength and improve reaction time.

“Athletes have a lot to think about when they are training,” Jake says. “Breathing shouldn’t be one of them.”

By combining the athletic benefits of nasal breathing with the performance enhancement of a mouthguard, Jake and Austin believe they have created the ultimate training accessory for serious athletes.

“I was surprised at how much more I breathed through my nose during a hard HIIT workout compared to when I simply ‘think’ about breathing through my nose,” says Ben Greenfield, a fitness coach, author, and former NSCA Trainer of the Year when utilizing the product.

“What’s great about this product is that we’ve developed it through research and science,” says Austin. “The OptiO2 line is not only designed to help athletes of all skill levels get the most out of every breath, but it’s also revolutionizing the way we breath as human beings, which is pretty groundbreaking and has been a inspiring to be a part of.”

We tend to associate certain positive outcomes with yoga, right? Improved flexibility always makes the list, as does lower stress and anxiety, the so-called “mind-body” benefits. But what about the just plain old “body” benefits? What can yoga do for things like muscle tone, weight loss (or healthy gain), and increased physical stamina? According to the experts, quite a bit. Yoga may not take the place of throwing around free weights, but it definitely can complement and enhance your gym workout.

There are three main types of muscle contractions. There are concentric contractions (muscle contracts as it shortens), eccentric contractions (muscle contracts as it lengthens), and isometric contractions (muscle contracts with no change in length). And for the latter, you are simply holding a pose, or pushing against an immovable object. Sound familiar, yogis? The static strength required to hold myriad yoga poses absolutely does enhance one’s muscular health. And it does so in a way that is more sparing to the joints than pumping iron.

Mary Irby, E-RYT 500 and Owner of White Crow Yoga, puts it this way:

“While our first thought of yoga benefits may lean toward creating mindfulness and increasing flexibility, practitioners are also presented with a great opportunity to build strength. When we incorporate poses such as the plank, 4-limbed staff, side plank, bridge, and locust, we introduce strength work into our practice. There are even ways to create strength in poses we may think of as traditionally used for flexibility. For example, in a standing forward fold, if we place our hands on a block or the floor and alternately abduct the leg straight out toward the side, we will definitely feel the strength building benefits in the legs and hips! Yoga provides a great way to increase strength throughout the body and the only equipment needed is a yoga mat, so it is a great way for all of us to add some strength training into our day.

So, it’s not a question of do I do my strength workout or my mind/body work today. In yoga practice, one can have both.

Master of Public Health and RYT-500 Melissa Shah, who regularly leads classes at Vanderbilt’s Osher Center for Integrative Medicine and studios such as Liberation Yoga and Blooma Nashville agrees:

“A regular yoga practice, often seen as solely “stretching,” offers so much more for body, mind, and spirit. Our body is a vessel for transformation, and yoga is an incredibly valuable tool for strengthening our vessel . . . Many of the clients I see suffer from some degree of joint pain. Yoga offers tools to build muscular strength around the joints to reduce pain and prevent further injury. Since almost every yoga posture requires some degree of both strength AND flexibility, it makes it an ideal method for building strength through the entire body in a way that is sustainable.”

In addition to the aforementioned misconceptions, there is also a disparity between the sexes when it comes to yoga participation. More specifically, there seems to be an opinion shared among many of my brethren that yoga is a “woman thing.” Well, I have to tell you, fellas, that this is just flat wrong. Yoga is challenging and fruitful physically for a variety of reasons, and there have been more than a few professional football players over the years, including Ray Lewis and Nashville’s own Eddie George, who have counted themselves as yogi practitioners. Again, this is because yoga manages to be both physically challenging and relaxing and therapeutic all at the same time! It’s a tough workout, but in a way that actually leaves you feeling better when it’s over.

My hope is that some of you who are still hesitant to hit the mat and give yoga a try will now open yourselves up to the possibilities. And for those of you who are already yogis, please remember that on some days, your practice should emphasize the more challenging, muscle-building aspects of yoga. Along with the mind/body benefits. Yoga can count as part of your regular strength work, too. Be well, Nashville, and Namaste.

Blood flow restriction (BFR) is an evidence based exercise training method for the widespread population that combines tourniquet technology and lite intensity resistance training to build muscle mass, strength, cardiovascular capacity and bone density that is similar to higher intensity training.

BFR training is performed by applying an inflatable tourniquet to the upper arms or upper legs (never all 4 at once), that is calibrated to the individual user by technology from a certified BFR specialist.

Reducing blood flow to a limb while performing lite intensity cardiovascular exercise or resistance training has shown to increase muscle oxygen demands in muscle, which encourage larger and greater force producing bundles of muscle fibers to become active.

These higher thresholds, fast twitch muscle fibers are quite particular and during normal conditions require heavier weight or near absolute muscle fatigue to be recruited; which is often difficult or not advised pre competition, during in-season competition, post injury/surgery, or within the aging community. In each of these cases, maintaining or increasing in muscle mass is critical for health and injury reduction, as per the American college of sports medicine. BFR has shown to positively influence similar high-intensity benefits while lifting loads as lite as 20% to 40% or a single repetition max, which commonly are not enough resistance or intensity.

Similarly, BFR has shown to be beneficial to cardiovascular capacity or VO2max adaptations in young, elderly and professional sports players who are unable to use high-intensity training like running due to cardiovascular restrictions, bone density, joint health, or are just limited in time. Typically, higher intensity exercises are needed to encourage positive cardiovascular changes, such as running within the 60% to 80% of heart rate reserve (HRR), with required durations of 30 to 45 minutes.

Findings with BFR have shown to increase cardiovascular capacity, circulatory fitness, and increase in muscle mass and strength while at intensities as low as 45% HRR. These outcomes appear to be explained by studies that have shown reductions in blood flow to the heart via tourniquet use, can be used to safely increase heart rate and arterial adaptations while using treadmill walking, riding a bike or even walking in a pool that can be beneficial for lower bone density/post injury/post-surgical patients.

BFR research began nearly 50 years ago, by Dr. Yoshiaki Sato, who was curious to explore why muscles burned when they became fatigued. His early curiosity led him to use an innertube from a bike tire to reduce blood flow to a limb. Since then, the US military, NASA, Sports Orthopedic surgeons, Biologist, Cardiovascular specialist and Neurologist from around the world have participated in over 1000 peer reviewed studies to peer further into the safety, benefits, and population specifics for applying BFR training in hospital settings, outpatient, and in the training room. What the studies have demonstrated so far, is that BFR training can be a game changer for many people wanting to get back to what they love to do and perform better.

As of 2018, BFR training became part of the American Physical Therapy association practice act, and since 2014 has been adopted into nearly all US professional sports rehab teams, Olympics, special forces rehab units, top orthopedic groups and with the help of other fellow researchers and educators such as myself, is now growing abroad in Europe, Australia, Ireland, and South America.

As a sports medicine/exercise physiologist lead Physical Therapist at Lifters Clinic here in Mount Juliet TN, a researcher in BFR here at our very own Belmont University, and co-founder of The BFR Pro’s, an unbiased BFR continuing education company; BFR has made up my life for the better of the last 5 years.

The amazing anecdotal stories that I have seen, in cases where fractures finally closed, muscles bounced back after an ACL surgery, reduced knee pain for osteoarthritis/rheumatoid arthritis patients, faster recovery periods post sport-related injuries; and elderly patients making leap and bounds to positive muscle mass, strength, and cardiovascular changes have all been a humbling life-changing experience.

For many of my patients, BFR directly helped lower the threshold and barrier of entry to experience positive change and a path forward.

BFR training is easy to use, hard to misuse, safe, effective, and becoming mainstream. We in the field say that BFR is better for results, backed by science, and changing people’s lives.
