Improve your sports performance using breath control
Using science and tech to drive better sports endurance
Your breath is your foundation. It's the one system you can consciously train that directly impacts every other system; cardio, neuro, muscular, and psychological. And yet, it’s so often overlooked.
We spoke to WellO2’s Gwyn Williams about the ways you can improve your breath control for better performance, whether you’re an athlete or an amateur.
Breath control is often the difference between sustaining performance and falling short. At a basic level, efficient breathing helps oxygenate your muscles, manage your heart rate, and maintain composure under pressure.
The “right way” to breathe involves nasal breathing (breathing through your nose), diaphragmatic control (using your breathing muscles to regulate your breath pattern), and rhythm. But every athlete is different, so understanding your patterns and training your respiratory system specifically is key.
Improving breath control isn't just about technique; it's about conditioning. You wouldn't ignore strength training for your legs, so why neglect the muscles involved in breathing? When you improve your breathing mechanics and respiratory muscle strength, endurance and recovery see massive gains.
There are several. Deconditioning (lack of physical activity resulting in loss of physical function), poor posture, stress, asthma, and even long COVID can reduce lung efficiency. Lifestyle also plays a big role. Sedentary habits and screen time can affect breathing patterns, often causing shallow chest breathing.
For athletes, overtraining without specific respiratory work can also limit performance.
Genetics can also play a part, but most limitations are highly trainable when approached the right way.
Breathwork techniques like box breathing, apnoea training, and CO₂ tolerance exercises are valuable. But to truly enhance the mechanics and strength of breathing, tools like the WellO2 Breathing Trainer and MyBreath smart mouthpiece come into play.
WellO2 combines resistance breathing and warm steam to strengthen the respiratory muscles while also opening the airways. It’s one of the only devices that trains both inhale and exhale functionally. The MyBreath mouthpiece adds a layer of smart feedback by tracking flow, pressure, and consistency to help you visualise and improve your technique in real-time.
Many tools target one aspect: resistance, humidification, or feedback. WellO2 is unique because it combines them all. It offers adjustable resistance for both inhalation and exhalation. Plus steam inhalation relaxes and opens airways. You get immediate and long-term benefits, whether you're dealing with a respiratory condition or pushing your athletic limits.
The MyBreath mouthpiece makes it smart. You can now quantify your breath training in the same way you’d track your running pace or wattage on the bike. That level of feedback is game-changing.
WellO2 is a highly versatile tool that fits seamlessly into an endurance athlete’s routine. It can be used during warm-ups to open the lungs, activate the respiratory muscles, and prepare the body for high-performance efforts. Post-training, it supports faster recovery by promoting relaxation and helping the body transition into a parasympathetic state (your rest and digest mode).
Just 5 to 10 minutes a day can make a noticeable difference, especially when used consistently. Athletes can also schedule its use within their training blocks, similar to how strength or mobility work is programmed. During high-volume phases, WellO2 helps boost stamina and improves respiratory endurance. In taper phases or during injury recovery, it offers a low-impact way to maintain lung function and stay connected to the breath.
Additionally, WellO2 is particularly helpful for preparing the respiratory system for challenging training environments like dry indoor air or outdoor conditions with high pollen levels. By moistening and conditioning the airways, it reduces irritation and helps athletes breathe easier, even in less-than-ideal settings.
Designed for all abilities
WellO2 is accessible to almost anyone, but like any training tool, progress starts gradually. WellO2 is a multipurpose tool that can help you whether you're training or not. But if you have a known respiratory condition, it's worth consulting with a healthcare professional first.
Start on a low resistance setting and build up as your respiratory muscles adapt. The key is consistency over intensity.
If you have a diagnosed respiratory condition, it’s best to consult a healthcare professional before starting.
