Controlled studies, university research, and peer‑reviewed trials show that KYMIRA® Infrared measurably improves key performance metrics across power, strength, explosiveness, endurance efficiency, and neuromuscular performance—all of which directly affect on‑field output and training quality.

1. Total Work Output & Average Power

Athletes wearing KYMIRA Infrared produce ~3.4% average and up to 8.7% maximum improvements in total work and average power during exertion—proven in controlled exertion trials.
[kymira.com]

2. Maximal Strength (MVIC)

Trials demonstrate increases in maximal voluntary isometric contraction (MVIC), indicating stronger force production and improved neuromuscular efficiency.
[kymira.com]

3. Explosive Power Metrics (CMJ, Take‑off Velocity, RFD)

KYMIRA improves multiple explosive‑output markers, including:

• Countermovement Jump (CMJ) height
• Take‑off velocity
• Eccentric Rate of Force Development (RFD)

These gains reflect higher neuromuscular readiness and sharper repeat‑effort power.
[kymira.com]

4. Endurance Efficiency & Oxygen Cost

Studies show KYMIRA reduces the oxygen cost of exercise and improves VO₂ kinetics, enabling athletes to sustain higher intensities with lower metabolic strain—critical for repeated high‑output phases.
[kymira.com]

5. Neuromuscular Recovery Performance (24–48h)

A peer‑reviewed Notre Dame (2025) study showed significant neuromuscular performance restoration at 24h and 48h, improving next‑session output, repeat‑effort capability, and recovery‑linked performance markers.
[kymira.com]

6. Grip Strength

Controlled testing demonstrated a 12.44% increase in grip strength after 90 minutes of wear—evidence of improved neuromuscular activation and blood‑flow‑driven output.
[kymira.com]

KYMIRA® Infrared reduces soft‑tissue injury risk by improving tissue quality, stability and fatigue resistance through active physiological mechanisms—not just passive compression. FIR emitted from KYMIRA’s embedded minerals increases nitric‑oxide–driven vasodilation, elevates local blood flow and tissue oxygenation (tcPO₂), and enhances cellular efficiency, which together improve muscle elasticity, joint mobility and tendon loading tolerance during high‑stress efforts. [kymira.com], [sports-insight.co.uk], [kymira.com]

Primary injury‑mitigation pathways

Greater perfusion → better elasticity & ROM. Increased microcirculation and oxygen delivery improve soft‑tissue extensibility and joint mobility—two modifiable risk factors for muscle strains and tendon issues. [kymira.com]

Lower inflammation & faster tissue repair. Studies report reductions in inflammatory markers, swelling, and accelerated cellular repair under targeted FIR; this helps small insults resolve sooner, limiting cascade injuries. [kymira.com]

Reduced oxygen cost & delayed fatigue. By improving cellular respiration efficiency and VO₂ kinetics, athletes sustain quality mechanics longer—reducing fatigue‑related technique breakdown, a common soft‑tissue risk driver. [kymira.com]

Quicker neuromuscular restoration between sessions. Peer‑reviewed data show significant neuromuscular recovery gains at 24–48 h, helping stabilisers and prime movers regain function before the next load. [kymira.com]

How programmes apply it (to influence risk)

Prime (30–90 min pre‑session): raise perfusion/elasticity before exposure to high stretch‑shortening cycles.

Perform (in‑session): sustain oxygen economy and local circulation during repeated high‑speed or contact phases.

Recover (2+ h post) & Sleep/Travel: resolve micro‑trauma faster and maintain tissue quality through congested schedules and long‑haul travel.

Bottom line for performance & medical staff

By improving perfusion and oxygenation, dampening inflammation, speeding repair, and reducing fatigue‑driven mechanics loss, KYMIRA® Infrared helps athletes arrive primed, stay robust under load, and bounce back quicker—key levers for lowering soft‑tissue injury incidence and protecting joints/tendons across the season. [kymira.com], [kymira.com], [kymira.com]

KYMIRA® Infrared accelerates recovery by increasing circulation, oxygenation, metabolic clearance, and neuromuscular restoration—allowing athletes to rebound faster between matches, heavy training blocks, and long‑haul travel. FIR emitted from KYMIRA’s embedded minerals drives nitric‑oxide‑mediated vasodilation, improved tissue oxygenation, and enhanced cellular efficiency, creating a continuous recovery stimulus during and after wear. [kymira.com], [kymira.com], [sports-insight.co.uk]

1. Faster neuromuscular recovery (24–48 hours)

The peer‑reviewed University of Notre Dame study (2025) found highly significant improvements in neuromuscular recovery at 48 h (p < 0.001) and earlier readiness at 24 h, demonstrating faster restoration of strength, power, and movement quality between sessions. [kymira.com]

2. Reduced soreness, inflammation & swelling

Clinical results show KYMIRA reduces inflammatory markers, swelling, and DOMS severity—key barriers to recovery between intense training days or fixtures. [kymira.com]

3. Improved metabolic clearance & oxygen efficiency

Infrared exposure reduces the oxygen cost of exercise and enhances VO₂ kinetics, helping athletes clear fatigue‑related metabolites more quickly and sustain performance quality across multi‑day cycles [kymira.com]

4. Elevated circulation & tissue oxygenation during inactivity (ideal for travel)

Studies show KYMIRA improves vasodilation and tissue oxygenation (tcPO₂) even at rest, which is vital during long‑haul flights, bus travel, and extended sitting—preventing the stiffness and poor perfusion that delay recovery.

Elite‑sport insights on kymira.com confirm that players use KYMIRA during travel to maintain readiness and reduce travel‑related fatigue. [kymira.com], [sports-insight.co.uk] [empireflippers.com]

5. Better overnight recovery & sleep quality

Athlete studies cited on kymira.com show 15.9% improved sleep quality and reduced fatigue and soreness, enabling athletes to “stack” recovery overnight and enter the next day fresher and more neurologically prepared. [mailerlite.com]

6. Seamless integration into elite recovery protocols

KYMIRA’s recommended workflow—30–90 min pre‑session priming, in‑session use, 2+ hours post‑session, and sleep/travel wear—provides a continuous, passive recovery stimulus with no additional staff load. [empireflippers.com]

Bottom line for performance & medical teams

KYMIRA® accelerates recovery by improving blood flow, oxygenation, inflammation control, metabolic efficiency, neuromuscular readiness, and sleep quality, enabling athletes to turn around faster, maintain higher training loads, and perform more consistently through congested schedules and travel demands. [kymira.com], [kymira.com], [kymira.com], [empireflippers.com]

Yes—KYMIRA Infrared should be worn throughout travel and sleep windows to counter the deconditioning effects of immobility (venous pooling, stiffness, reduced tissue oxygenation) and to arrive fresher and more “ready” for training or competition. KYMIRA’s travel protocol is explicit: wear during all hours of travel, pair with pre‑/post‑session use, and continue overnight for maximal carry‑over.

Why travel hurts readiness (and how infrared helps)

What travel does to athletes

• Prolonged sitting (>60–180 min) impairs breathing mechanics, increases stiffness (esp. thoracic/hip), and degrades cardiovascular efficiency—each eroding readiness and elevating soft‑tissue risk on arrival. [kymira.com]
• Restricted movement and dependent leg position elevate venous stasis risk; maintaining blood flow is central to mitigating DVT risk during long‑haul trips. [kymira.com]

What KYMIRA does in‑transit

• Increases nitric‑oxide–mediated vasodilation and microcirculation, supporting blood flow while seated. (Mechanism is core to KYMIRA’s FIR tech and referenced in their clinical results.) [kymira.com]
• Elevates tissue oxygenation (tcPO₂) and improves local perfusion—useful when movement is constrained. [kymira.com]
• Supports thermoregulation and comfort (less stiffness on arrival), with KYMIRA’s travel content recommending infrared garments for long trips. [kymira.com], [kymira.com]
• Improves sleep quality, which is often disrupted by time zones and late arrivals; KYMIRA cites a controlled sleep improvement when infrared is worn overnight. [kymira.com]

The elite‑sport protocol for travel days

Simple rule: Coverage and continuity. Keep infrared on for the full travel block; prime on arrival; sleep in KYMIRA that night.

Recommended sequence (example for a 5–8 h flight + light PM activation):

1. Pre‑departure (30–90 min): Wear KYMIRA base layers and socks to begin priming circulation and tissue oxygenation before immobilization.
2. In‑transit (gate → gate): Keep garments on for all seated periods (bus, airport, plane). Prioritize lower‑limb coverage (leggings/socks) to counter venous pooling; add tops for trunk/shoulder stiffness. [kymira.com], [kymira.com]
3. On arrival (within 2–3 h): Maintain wear through the activation/primer (mobility, tissue prep, low‑intensity aerobic); KYMIRA recommends starting sessions 30–90 min in advance to maximize perfusion.
4. Post‑activation (2+ h): Keep KYMIRA on for recovery to accelerate metabolic clearance and neuromuscular restoration.
5. Overnight: Sleep in KYMIRA to improve sleep quality/efficiency and reduce next‑day fatigue/soreness. [kymira.com]

Why this works: The above maps directly to KYMIRA’s defined Prepare → Perform → Recover → Sleep/Travel framework and is highlighted as effective during travel in their elite‑sport content.

What to issue on the road (kit list)

• Lower body: infrared leggings + compression socks (highest impact for venous return & tcPO₂ while seated). [kymira.com], [kymira.com]
• Upper body: long‑sleeve base layer or mid‑layer for trunk stiffness mitigation and comfort. [kymira.com]
• Night kit: sleepwear set for immediate post‑arrival nights. [kymira.com]

What data should performance/medical staff expect?

KYMIRA’s internal trial measures (used with pro teams) suggest the following patterns when protocols are followed during congested travel schedules:

• HRV and composite recovery scores (mRSI) improve within the first week of use, with athletes reporting less soreness and better freshness.
• Objective oxygenation/perfusion markers (e.g., tcPO₂) improve with FIR textiles, supporting faster readiness after immobilization. [kymira.com]
• Reduced oxygen cost of exercise and faster aerobic “switch‑on,” which can translate to better quality in the first training exposure post‑travel.

How to monitor on trips: Track HRV, resting HR, sleep duration/efficiency, RPE, and CMJ the morning after arrival; KYMIRA notes HRV shifts first, followed by sleep/recovery score gains with consistent overnight use.

KYMIRA® Infrared works best when used as a continuous, multi‑phase protocol that matches the biological time‑course of nitric oxide (NO) release, microcirculation improvements, mitochondrial up‑regulation, and neuromuscular restoration. Elite programmes follow a four‑stage cycle:

Prepare → Perform → Recover → Sleep/Travel

KYMIRA explicitly recommends protocolised durations for each stage, supported by peer‑reviewed data and internal professional‑sport trials.

1. PRE‑SESSION / “PRIME” (30–90 min before activity)

Wearing KYMIRA 30–90 minutes prior to high‑intensity work allows NO‑driven vasodilation, microcirculation and tissue oxygenation effects to peak. KYMIRA’s internal trials confirm that 90 minutes reaches optimal working effect, making this the gold‑standard priming window for elite athletes.

Physiological mechanisms activated in this window

• Increased nitric‑oxide production → vasodilation, elevated blood flow and oxygen delivery (Chen & Benardot 2023).
  Improves readiness and reduces early‑session stiffness.
• Elevated tissue oxygenation (tcPO₂) → improved muscle extensibility & warm‑up quality. [kymira.com]
• Improved mitochondrial activation & angiogenic signalling → accelerated aerobic system “switch‑on".
  Critical for high‑speed running, repeat‑sprint sports, combat and endurance events.

Elite application examples

• Warm‑ups feel easier; RPE during early sets drops noticeably.
• Higher CMJ and take‑off velocity achieved even before core session loads.

Recommended garments

Lower‑limb coverage (leggings + socks) for perfusion; long‑sleeve tops for trunk stiffness/tissue temperature.

2. IN‑SESSION / “PERFORM” (training & competition)

KYMIRA continues to deliver active physiological effects during exertion, making it unlike passive compression garments. It sustains mechanical quality and reduces fatigue‑linked technical breakdown. KYMIRA recommends wearing garments through the full duration of sessions.

Performance‑linked benefits (measured in trials)

• Increased total and average power output during exertion to exhaustion. (Bond et al., 2026 pre‑pub)
  → Enables better work density in conditioning blocks.
• Higher maximal voluntary isometric contraction (MVIC) and improved neuromuscular efficiency, stabilisation & joint protection.
• Improved VO₂ kinetics / reduced oxygen cost of exercise (Worobets et al., 2015 & VitaLibrary 2025)
  → Athletes sustain quality for longer under high load.

Elite application examples

• More consistent outputs in repeated‑sprint tests.
• Reduced decrements in jump metrics late in session (CMJ, take‑off velocity).
• Stable technique deeper into contact‑or collision‑based sessions.

3. POST‑SESSION / “RECOVER” (2+ hours minimum)

KYMIRA instructs teams to use garments for at least 2 hours post‑activity, and ideally as many hours as possible within 24 h.
This window is where significant biological recovery acceleration has been documented.

Proven recovery effects

• Neuromuscular restoration (24–48 h) including CMJ restoration, take‑off velocity, eccentric rate of force development. (Lever et al., 2025)
  → Athletes “bounce back” faster.
• Reduced inflammatory markers, swelling & increased anti‑inflammatory responses (Gale 2006; Gordon 2009).
  → Faster tissue repair & reduced microtrauma accumulation. [kymira.com]
• Accelerated metabolic waste clearance & lower fatiguing metabolites. (Bond et al., 2026 pre‑pub)
  → Reduced DOMS and improved next‑day readiness.
• Improved Mean Recovery Stress Index (mRSI) and HRV within the first week of use.
  → Objective biomarker confirmation of systemic recovery.

Elite application examples

• Teams report significant reductions in soft‑tissue injury incidence when KYMIRA is consistently worn post‑session. (England Rugby reports up to 80% injury reduction).
  
  [kymira.com]
• Higher availability rates in congested fixture windows.

4. SLEEP & OVERNIGHT USE (every night; essential after games & travel)

Sleep is a major recovery multiplier. KYMIRA recommends wearing infrared garments throughout sleep for maximal benefit.

Measured sleep‑related outcomes

• 15.9% improvement in sleep quality and
• 15.8% reduction in fatigue &
• 13.6% reduction in soreness
  when KYMIRA is worn overnight (University of Texas study).
  [kymira.com]

Mechanisms during sleep

• Sustained NO‑mediated circulation & oxygen delivery optimises overnight tissue repair.
• Increased angiogenic & mitochondrial signalling supports long‑term adaptation. (Bond et al. pre‑pub)
• Lower systemic physiological stress → improved HRV trends by morning.

Elite application examples

• Athletes report waking less stiff, feeling “fresher,” and regaining session quality faster over multi‑day tournaments or back‑to‑back fixtures.

5. TRAVEL USE (continuous wear for all hours of travel)

Travel introduces immobility, venous pooling, stiffness, and reduced oxygenation. KYMIRA explicitly instructs teams to wear garments for all hours of travel.

Why it matters

• FIR + compression (e.g., socks) significantly stimulates blood flow—helpful for preventing travel‑related circulation issues & stiffness.
• Reduces jet‑lag‑related fatigue; supports better sleep once at destination. [kymira.com]

One of the most compelling real‑world results comes from England Rugby, which reported an 80% reduction in soft‑tissue injury rates after integrating KYMIRA protocols—with no other protocol changes made. [kymira.com]

This is one of the strongest practical indicators that KYMIRA’s improvements in circulation, inflammation control and tissue quality translate directly into real‑world season outcomes.

2. Higher Player Freshness & Availability After Travel, Tournaments & Dense Schedules

Performance directors working with elite teams note that athletes are fresher, less stiff, and more available after heavy sessions and long‑distance travel when wearing KYMIRA. [kymira.com]

In congested schedules, teams reported athletes being ready to train again sooner, gaining back training days that would normally be lost to soreness or stiffness.

3. Proven Performance Gains — Up to 8.7% on First Use

Loughborough University’s data (pending publication) shows that athletes perform up to 8.7% better in their first wear of KYMIRA infrared apparel. [kymira.com]

This level of improvement is extremely difficult to achieve through normal training alone, highlighting KYMIRA’s ability to actively enhance physiology (ATP behaviour, oxygenation, NO release).

4. Faster Recovery: Neuromuscular, Cardiovascular & Metabolic

Teams using KYMIRA report that athletes:

• Recover more quickly from heavy exertion
• Experience less DOMS, stiffness and muscle fatigue
• Restore CMJ, take‑off velocity and other neuromuscular markers within 24 hours [kymira.com]

These subjective experiences match the objective improvements recorded in KYMIRA’s research (e.g., reduced fatiguing metabolites, enhanced mitochondrial signalling, improved angiogenesis).

5. Accelerated Rehabilitation From Injury & Surgery

Elite physios, osteopaths and medical practitioners report:

• Accelerated injury rehab timelines
• Improved programme compliance
• Less recovery discomfort during rehab phases [kymira.com]

Clinical studies cited by KYMIRA show infrared stimulation increases cellular healing by 140–210%, matching these real‑world outcomes.

6. Improved Sleep, HRV and Recovery Scores in Daily Athlete Monitoring

KYMIRA’s applied case studies also demonstrate:

• Improved sleep quality
• Higher blood oxygen levels
• Quicker heart‑rate recovery during intervals
• Faster bounce‑back between stages (e.g., cycling)
  

These results mirror what elite coaches report anecdotally: athletes simply feel better, recover faster and maintain high readiness through congested competition windows.

Summary for S&C, Medical & Performance Directors

Across elite teams, KYMIRA consistently delivers real‑world, measurable outcomes:

• 80% fewer soft‑tissue injuries (England Rugby)
• Up to 8.7% performance improvement (Loughborough trial)
• Faster recovery and improved readiness within 24–48 h
• Accelerated rehab and reduced discomfort
• Better sleep, HRV and athlete freshness
• Higher and more sustainable training loads

These are not consumer‑level anecdotes—they are high‑performance, evidence‑backed operational results from top professional environments.

KYMIRA® sits in a completely different category from compression garments and passive recovery tools. It is an active, physiological technology—not a passive mechanical aid—making it closer to an “always‑on” recovery and performance system. This distinction is strongly emphasised across KYMIRA’s official performance and technology literature.

1. KYMIRA vs. Traditional Compression Garments

Compression = mechanical / external pressure

Compression primarily reduces muscle oscillation and may modestly affect venous return. However, systematic reviews repeatedly show little to no impact on measurable performance metrics such as VO₂ kinetics, endurance, maximal strength or sustained power. [kymira.com]

KYMIRA = active physiological change

KYMIRA’s infrared garments convert body heat into far‑infrared light, penetrating deep into tissue to trigger NO release, increased microcirculation, improved tissue oxygenation, mitochondrial activation and angiogenic signalling. [kymira.com]

What this means in practice

• KYMIRA actively increases blood flow via NO‑mediated vasodilation, rather than relying on mechanical squeeze.
• Athletes show increased power output, better endurance, lower oxygen cost, and faster recovery—changes compression has not been shown to produce. [kymira.com]

Bottom line:

Compression is passive and perceptual; KYMIRA is biologically active and performance‑changing.

2. KYMIRA vs. Traditional Recovery Methods (e.g., ice baths, compression boots, massage)

Traditional tools are episodic and time‑bound

Cold‑water immersion, contrast bathing, massage, or pneumatic compression require:

• scheduling
• therapist time
• equipment availability
• athlete compliance
• travel to the facility

This makes them difficult to apply during travel, at hotels, or between games.

KYMIRA is always‑on, frictionless recovery

Elite‑sport pages emphasise that KYMIRA protocols are available anywhere, require no time block, and do not degrade with use—athletes recover simply by wearing the garments. [kymira.com]

KYMIRA can also be combined with other active protocols (e.g., pneumatic compression boots) for stacked benefits. [kymira.com]

Performance staff highlight operational advantages

• Frees medical teams from labour‑intensive modalities
• Adds recovery during travel and sleep (critical during congested schedules)
• Increases player availability without increasing staff workload [kymira.com]

Bottom line:

Traditional tools require appointments. KYMIRA works 24/7, with zero added staff time.

3. What makes KYMIRA uniquely valuable in elite sport

Active physiological technology (not passive)

Infrared stimulation creates true biological change—NO release, improved oxygenation, tissue elasticity, mitochondrial efficiency [kymira.com]

Scientifically validated

KYMIRA is backed by 10+ peer‑reviewed studies, University of Notre Dame data, and real‑world results where teams see up to 8.7% performance gains and 80% injury reduction. [kymira.com]

Round‑the‑clock usability

Travel, sleep, downtime, pre‑activation, recovery windows—all covered. [kymira.com]

High athlete compliance

KYMIRA is “as easy as getting dressed,” leading to far higher adherence than ice baths, boots, or contrast therapy. [kymira.com]

Yes. KYMIRA® Infrared garments are medically recognised, certified as safe for continuous use, and fully compliant with global sports regulations. This is one of the core reasons elite medical teams are comfortable deploying the technology across recovery, travel, sleep, rehabilitation and matchday cycles.

• 80% reduction in soft‑tissue injuries reported by England Rugby after adopting KYMIRA protocols (with no other changes). [kymira.com]
  
• Athletes show improved freshness, reduced stiffness, and better availability following high‑load periods and long‑haul travel. [kymira.com]
  

These outcomes are consistent with the physiological improvements seen in the lab (circulation, oxygenation, inflammation control).

6. What Makes KYMIRA’s Evidence Base Unique?

Breadth of validation

Studies span:

• Sports physiology
• Clinical medicine
• Tissue repair
• Neuromuscular recovery
• Sleep science
• Mitochondrial & angiogenic signalling [kymira.com]

Consistency across contexts

The same biological mechanisms (NO, oxygenation, microcirculation) appear across:

• pre‑activation
• performance
• recovery
• sleep
• travel
  
  ensuring the garment has measurable value throughout an athlete’s daily load cycle.

KYMIRA® is uniquely effective in congested competition windows because it accelerates recovery, sustains tissue quality, reduces fatigue accumulation and enhances readiness across consecutive performance days. These outcomes are documented in KYMIRA’s clinical research and elite‑sport case studies.

1. Faster Recovery Between Consecutive Events

Multi‑day competition demands rapid turnaround between high‑load exposures. KYMIRA accelerates recovery through several proven mechanisms:

Neuromuscular restoration within 24–48 hours

KYMIRA research shows CMJ, take‑off velocity, eccentric RFD, and explosive strength markers return significantly faster when infrared garments are used post‑exertion.

Reduced inflammation & quicker tissue repair

Clinical studies show reductions in inflammatory markers and swelling, with increased anti‑inflammatory responses and accelerated tissue repair. [kymira.com]

Enhanced metabolic clearance

Athletes exhibit lower fatiguing metabolites and faster restoration of homeostasis after sessions, reducing cumulative soreness and improving next‑day readiness.

Impact in tournaments: teams see better day‑to‑day freshness, less DOMS, and steadier neuromuscular output.

2. Improved Endurance & Sustained Power Across Days

Back‑to‑back fixtures require athletes to maintain high outputs with minimal recovery time.

Increased total and average power output

KYMIRA increases both maximal and sustained power during exertion. (Bond et al., 2026 pre‑publication) [kymira.com]

Lower oxygen cost of exercise

Reducing oxygen demand allows athletes to sustain high‑intensity efforts with less physiological strain across repeated days. (Worobets et al., 2015) [kymira.com]

Faster activation of the aerobic system

Improved VO₂ kinetics support repeated-sprint and endurance-heavy schedules. (Bond et al., 2026 pre‑publication)

Why this matters: fatigue compounds across multi‑day events, but KYMIRA helps slow that decline.

3. Increased Player Availability & Reduced Soft‑Tissue Incidents

Availability matters more than freshness in tournaments—KYMIRA has demonstrated real-world injury‑risk reductions.

Improved tissue elasticity & joint mobility

Infrared increases circulation and oxygenation, improving muscle extensibility and resilience under fatigue—critical in congested schedules.[kymira.com]

This allows athletes to tolerate repeated exposures to high‑speed running, collisions and heavy load.

4. Better Sleep & Travel Recovery During Multi‑Day Events

Tournament fatigue is driven not just by workload but by disrupted sleep and travel demands.

Wear-through-travel protocols maintain readiness

KYMIRA recommends wearing infrared garments through all travel hours, ensuring continuous recovery even when athletes are sedentary or jet-lagged.

This is crucial in tournament formats with rapid relocation between venues.

5. High Compliance Enables Continuous Recovery in Compressed Schedules

Unlike ice baths, boots or therapist-led modalities, KYMIRA requires zero time allocation and works passively:

High compliance means teams actually use the recovery method in multi‑day formats—where time and staffing are limited.

6. Tournament-Optimised Usage Protocol

Pre‑Event (30–90 min)

Prime circulation, oxygenation and tissue elasticity.

During Event

Maintain oxygen economy and microcirculation during sustained or repeated high intensities.

Post‑Event (2+ hours)

Accelerate recovery and reduce metabolic/fatigue carryover into the next match or stage.

Sleep & Travel

Maintain tissue repair and readiness overnight and during transport between stages.

These are KYMIRA’s official usage recommendations for elite athletes.

Summary for Performance & Medical Staff

KYMIRA supports multi‑day competitions by:

• Accelerating recovery (neuromuscular + metabolic) between sessions
• Maintaining performance output (power, VO₂ efficiency, reduced oxygen cost)
• Improving sleep & reducing fatigue accumulation overnight
• Enhancing resilience and reducing soft‑tissue injuries
• Ensuring high compliance across compressed schedules
• Supporting readiness during travel between stages

Result: athletes stay fresher, more available, and more robust across consecutive days — giving teams a competitive advantage in tournaments, championships and back‑to‑back fixtures.

The most popular first deployment of KYMIRA Infrared in elite sports teams, is typically in the recovery and sleep protocols. Teams typically include protocols for travel within this regime, as KYMIRA Infrared is so uniquely portable and passively operational, compared to many other options.

The most popular KYMIRA Infrared products to deploy for these protocols is:

Daytime Recovery:

1. Recovery Baselayers

2. Compression Socks

3. Recovery Tracksuits

Recovery Wear

Infrared Socks

Nighttime Recovery:

Recovery Sleepwear

Sleepwear

Teams deploy KYMIRA Infrared performance wear for muscle priming before training, and for performance optimisation during performances (matches, games, championships). Priming muscles with infrared (at least 30 minutes, 90 minutes optimal) before, is shown to reduce the risk of soft tissue injuries. Wearing KYMIRA Infrared during training and performance, is shown to boost athletic performance outcome measurements by up to 8.7% from first wear, and clinically causes greater power, endurance, strength, mobility, and flexibility.

The most popular KYMIRA Infrared products to deploy for these protocols is:

Performance Baselayers. Full coverage is advised, but some sports prefer a 3/4 length legging, short, or short sleeve baselayer.

Performance Wear

KYMIRA custom make performance baselayers for elite teams worldwide, and will do custom colour, cobranding, or non branded items to meet regulations and preferences. These are created in partnership with their in house team members.

KYMIRA also makes sport specific performance items, such as golf wear, cycling, tri suits for these activities.

No. KYMIRA’s infrared technology cannot wash out and does not degrade, even after years of use.

Unlike coated infrared fabrics used by some brands, KYMIRA embeds its infrared‑emitting minerals inside the fibres themselves, not applied as a surface finish. This means:

• The technology is locked into the yarn for the lifetime of the garment
• It never diminishes with washing or use
• Full physiological impact (NO production, circulation, oxygenation, mitochondrial response) remains stable through the entire product lifecycle

This makes KYMIRA highly reliable for high‑performance environments where consistent physiological output matters.

No. KYMIRA does not cause overheating. It improves thermoregulation without trapping heat.

KYMIRA’s infrared fabrics do not function like heating garments. They do not add additional heat to the body. Instead, the fabric:

• Re‑emits far‑infrared (FIR) waves in a beneficial spectrum back into the wearer. This does not produce a heating effect, nor any warm sensation on the skin. These waves cause cellular activation and regeneration inside the body.
• Helps the body maintain optimal thermoregulation by increasing vasodilation, blood circulation, and cellular energy, helping the body to remain more temperate and stable by warming, sweating or cooling quicker to adapt to it's environment.
• Supports improved circulation and tissue oxygenation, which can enhance comfort and reduce stiffness in both warm and cold environments.

This is one of the reasons why KYMIRA is used across climates—from cold‑weather endurance sport to indoor elite team sports—without thermal discomfort or overheating risk.

KYMIRA and infrared saunas both use far‑infrared light, but deliver entirely different use‑case benefits. KYMIRA provides continuous, targeted FIR stimulation during movement, recovery, travel and sleep, whereas saunas provide short‑duration, high‑heat whole‑body exposure.

Mechanism & heat load

• KYMIRA Infrared: Bio‑ceramic minerals are embedded within the fibres and re‑emit a fraction of body heat as far‑infrared (FIR)—no external heat is added. You get the vascular and cellular effects (e.g., nitric‑oxide–mediated vasodilation, improved tissue oxygenation) without thermal stress. [kymira.com], [kymira.com]
• Infrared saunas: Deliver FIR via electrical emitters at elevated ambient temperatures; the benefits arise alongside heat stress, which is timing‑sensitive around training and competition. [kymira.com]

When and where athletes can use them

• KYMIRA: Wear pre‑session (30–90 min) to prime, during to support oxygen economy, post (2+ h) to accelerate recovery, and overnight/through travel to maintain readiness. No therapist, no equipment, and works anywhere—lockers, buses, planes, hotels. This is why KYMIRA frames it as an “always‑available protocol.” [kymira.com], [kymira.com]
• Sauna: Facility‑dependent and time‑boxed. Useful as a scheduled recovery modality, but not usable in travel windows, during sleep, or on the sideline; and the added heat can be counterproductive if mis‑timed close to performance. [kymira.com], [kymira.com]

Evidence relevant to elite sport outcomes

• KYMIRA: Cited improvements in circulation, tcPO₂, reduced oxygen cost of exercise, and faster neuromuscular recovery (e.g., CMJ, take‑off velocity, eccentric RFD), plus inflammation reductions—all directly applicable to congested schedules, back‑to‑backs, and tournaments. [kymira.com]
• Sauna: Can support general recovery and relaxation via heat‑induced cardiovascular responses, but lacks the continuous, field‑deployable profile that lets performance staff stack marginal gains across pre‑/during/post, sleep, and travel windows. [kymira.com], [kymira.com]

Bottom line for performance & medical directors

• Use KYMIRA daily as a non‑heat, always‑on FIR solution that integrates into every phase of the athlete day (prime → perform → recover → sleep/travel), with high compliance and zero logistical overhead. [kymira.com], [kymira.com]
• Keep infrared saunas as an optional, scheduled adjunct where appropriate under medical guidance—valuable for certain recovery contexts, but not a replacement for the continuous support KYMIRA provides. [kymira.com]
