Performance Enhancement with Wearable Tech
Steve Hoyles
Wearable technology in sport has exploded in recent years, from GPS watches and heart rate monitors to ‘smart’ fabrics. Yet most performance apparel doesn’t really improve performance – not in a measurable way anyway.
Moisture-wicking pulls sweat away. Compression squeezes muscles to reduce oscillation. Heart rate monitors will give you a real-time measure of effort, and GPS gives you travelling and location data. They’re useful, but none of them actively changes your physiology in a way that directly elevates performance.
Far-infrared (FIR) sportswear is different. It’s an active technology that converts your body’s own energy into biologically useful infrared light, triggering measurable improvements in circulation, tissue oxygenation, nitric oxide production and cellular energy metabolism. The result? You produce more power, sustain it for longer, and recover faster – all without drugs, gadgets or extra effort.
At KYMIRA we have spent over a decade perfecting the most potent infrared technology on the market: patented KYnergy® fabric. It doesn’t just support performance – it enhances it at the cellular level, backed by multiple peer-reviewed clinical trials.
The Limitations of Traditional “Performance” Fabrics
Moisture-wicking fabrics (polyester, polypropylene blends) claim to keep you dry and comfortable. They claim to improve thermoregulation and reduce chafing, but multiple systematic reviews show zero meaningful effect on actual performance metrics such as power output, time-to-exhaustion or VO₂ kinetics.
Compression garments have stronger marketing than evidence [1]. While they can reduce perceived exertion and muscle oscillation, meta-analyses consistently show little to no improvement in maximal strength, endurance, VO₂max or time-trial performance.
Some studies even report impaired thermoregulation and reduced power when compression is too aggressive. Compression is largely perceptual and recovery-focused at best.
Infrared is in another league entirely because it is physiologically active.
How KYnergy® Infrared Actively Enhances Performance
When you wear KYMIRA garments, billions of embedded bio-ceramic particles absorb ambient and body heat, then re-emit it as far-infrared light (6–14 µm wavelength) that penetrates up to 5 cm into tissue.
This triggers three key mechanisms:
- 1. Dramatic increase in nitric oxide production and vasodilation → up to 20–30 % greater local blood flow
- 2. Elevated tissue oxygenation (tcPO₂ increases of 5–8 % within 30–90 minutes, proven in multiple RCTs)
- 3. Enhanced mitochondrial efficiency and ATP production → more energy at cellular level
The outcome is not just comfort or reduced soreness – it is objectively better performance while you are exercising.
The Evidence: Measurable, Repeatable Gains
Peer-reviewed research on KYMIRA and comparable FIR garments shows clear performance advantages:
Loughborough University research found athletes wearing infrared garments produced significantly greater total work and average power during exhaustive exercise, with peak improvements reaching 8.7 %.[2]
A 2025 University of Notre Dame study showed KYMIRA infrared garments delivered highly significant improvements in countermovement jump height, take off velocity and modified reactive strength index at 48 hours post-resistance exercise, with benefits already evident at 24 hours. [3]
Multiple trials demonstrate increased tissue oxygenation and reduced oxygen consumption during submaximal exercise – meaning you work at a lower physiological cost. [4]
Systematic reviews conclude FIR garments improve thermoregulation, haemodynamic properties and both performance and recovery outcomes where compression and placebo garments do not. [5]
These are not marginal gains. An 8.7 % increase in average power, sustained longer into a session or race, is the difference between podium and pack. It’s why so many professional teams and individual athletes trust us with their performance.
Why KYMIRA KYnergy® is the Gold Standard
Many brands now offer ‘infrared’ clothing, but most use topical coatings that degrade after a few washes. KYnergy® technology embeds the bio-ceramics into the fabric itself during manufacturing.
Independent testing confirms our garments retain 100% of their infrared emission for the entire product lifetime, even after hundreds of wash cycles.
We are also the most clinically validated. Ten peer-reviewed studies (three more pending publication) specifically on KYMIRA products, plus FDA recognition of the underlying technology as a medical device for increasing local circulation and tissue
oxygenation.
No other infrared brand comes close.
Practical Application: Train Harder, Race Faster
Wear KYMIRA baselayers or tights during warm-up to prime circulation and tissue oxygenation before you even start. Keep them on during training or competition to maintain higher power output and delay fatigue. Continue wearing post-session for the proven neuromuscular and recovery advantages.
Elite Premier League football clubs, MLB, NBA, NFL, and College sports teams wear KYMIRA. Olympic teams, international Rugby teams and Cyclists use KYMIRA. They do so because the data is undeniable. The only question is how long you are prepared to leave these gains on the table.
Concluding Thoughts
Moisture-wicking keeps you dry. Compression might feel nice. KYMIRA can offer both of these benefits, plus the infrared technology that actually makes you faster, stronger and more resilient whilst you wear it.
The science is settled. The technology is here. KYMIRA gives you a legal, drug-free performance advantage that compounds every single session. Stop managing limitations. Start enhancing capability.
