From guesswork to physiology-based training đŻ
Meet Tom from @levelup.endurance â an endurance coach who transformed how he trains amateur athletes in running, cycling, and triathlon.
The problem? Traditional 20-minute power tests were time-consuming, imprecise, and left too much room for uncertainty.
The solution? INSCYD Physiological testing that provides objective data in minutes â helping coaches understand athletes performance better:
â Unique phenotype & energy systems
â Glycogen reserves & fueling strategy
â Personalized race strategies based on real physiology
â Exact training zones based on unique athletes physiology
"It's like having a virtual lab that eliminates the guesswork" - Tom
The result? Athletes are shocked at how much insight comes from such quick protocols, and they finally understand WHY their training works.

A peer-reviewed study just validated once again what we built.
Published in the International Journal of Sports Science and Physical Education (2026), INSCYD researchers compared the Power Performance Decoder against gold standard ergospirometry â achieving a Pearson correlation of 0.93â0.98, with a bias as low as Îâ0.21 ml·minâ»Âč·kgâ»Âč.
The reason it works where other field models fail? VLamax. Most VOâmax estimation models assume a fixed glycolytic energy contribution across all athletes. INSCYD accounts for each athlete's individual maximal lactate production rate â and the authors suggest this likely contributed to the accuracy advantage.
The validated protocol: 2 sprints of ~20 seconds + 2 all-out efforts (the study used 3 min + 6 min). No lab. No gas analyzer. Fits in a normal training session.

đŸ Save this â your athletes deserve testing that can actually detect their progress.

The real danger isn't a bad test.
It's the feedback loop that follows.
Train â Test â See a right shift â Think it's working â Keep training the same way â Test again â Another right shift â Keep going.
Every cycle reinforces the wrong direction.
Sebastian Weber on the compounding trap of using lactate curves as your only feedback on training quality â and why, sooner or later, everyone who repeats this cycle ends up in a place where the data can't tell them what went wrong.

A right shift in the lactate curve can come from losing anaerobic power.
That's the danger.
The training that harmed your athlete â that stripped their ability to sprint, attack, and change pace â shows up as a positive test result.
The curve shifted right.
The coach thinks: training is working.
The athlete is actually getting slower.
Sebastian Weber has seen this exact pattern in professional road cycling, Olympic-level swimming, cross-country skiing, and kayaking.
And it's invisible if you only look at the curve.

Utdrag ur en triathlets trÀningsdagbok.
Han trodde att han trÀnade rÀtt.
Datan visade nÄgot annat.
Hektiskt arbete inom vÄrden. SmÄbarnsfar. Hus, bil, kolonilott och allt annat. TvÄ kommande stora tÀvlingar. Han trÀnar konsekvent och ger allt under de fÄ timmar som ÄterstÄr i en kalender fylld av Positivt och negativ stress. StÄr still.
Första metaboliska testet görs.
Resultatet Ă€r tydligt: vid en intensitet dĂ€r han sjĂ€lv kĂ€nner sig lugn och kontrollerad Ă€r han redan djupt inne i sina kolhydratdepĂ„er. Hans fettförbrĂ€nningssystem â motorn som mĂ„ste bĂ€ra honom genom ett halvdistans triathlon â Ă€r knappt utvecklat.
Han hade trÀnat i flera Är. Om Àn sporadiskt. Med fel brÀnsle.
Fem mÄnader senare enligt plan, ett nytt test.
FatMax-zonen, den gröna zonen i grafen till höger, har förskjutits markant. Kroppen förbrÀnner nu fett vid intensiteter dÀr den tidigare frÀmst anvÀnde kolhydrater.
Laktatansamlingen börjar senare. Han kan cykla snabbare under lÀngre tid innan kroppen gÄr in i det röda omrÄdet. Mer metabol flexibel.
Inte för att han trÀnade mer.
Utan för att han för första gÄngen förstod vad kroppen faktiskt behövde.
Det hÀr Àr ingen slump.
Det Àr data. Baserat pÄ energisystem som tar oss framÄt.
Less lactate production sounds like progress.
For a marathon runner or Ironman athlete? It is.
You want to spare carbohydrates. Burn more fat. Go longer.
But for:
â Road cyclists
â Swimmers
â Cross-country skiers
â Soccer players
â Anyone who needs to follow an attack, change pace, or sprint to the line
âŠreducing glycolytic activity is the opposite of what you want.
Your sport's energy demands determine whether a right curve shift is good news or a red flag.
Sebastian Weber on why "one size fits all" lactate interpretation is costing athletes their performance.

Att mĂ€ta kroppssammansĂ€ttning (âbody compositionâ) Ă€r mycket mer Ă€n bara kroppsfett. MĂ„nga fokuserar enbart pĂ„ fettprocent, men kroppssammansĂ€ttningen pĂ„verkar prestation pĂ„ flera viktiga sĂ€tt, sĂ€rskilt inom uthĂ„llighetsidrott.
En central poĂ€ng handlar om laktat. Laktat mĂ€ts i millimol per liter blod, men vi glömmer sjĂ€lva âliterâ-delen. Eftersom laktat sprids i kroppsvatten spelar mĂ€ngden vatten i kroppen stor roll. En person med högre fettprocent har generellt mindre kroppsvatten procentuellt, medan en person med mer muskelmassa har mer vatten, eftersom muskler bestĂ„r av ungefĂ€r 75â78 % vatten. DĂ€rför ska inte resultatet pĂ„ laktatmĂ€taren jĂ€mföras mellan individer om man ocksĂ„ inte tagit kroppskomposition i beaktning.
Om vi kopplar detta till trÀning och prestation:
* Mer muskler innebÀr mer kroppsvatten.
* Mer muskler innebÀr ocksÄ större lagringskapacitet för glykogen.
* Glykogen Àr kroppens viktigaste energikÀlla vid hÄrd trÀning.
Glykogen lagras lokalt i musklerna och inte enkelt kan flyttas mellan olika delar av kroppen. Exempelvis hjÀlper inte glykogen i överkroppen sÀrskilt mycket för benen under löpning eller cykling.
Ett exempel dĂ€r tvĂ„ personer har samma lĂ€ngd och vikt men olika kroppsfettprocent (15 % respektive 25 %). Personen med lĂ€gre fettprocent och mer muskelmassa kan lagra betydligt mer glykogen â ungefĂ€r 120 gram mer enligt exemplet. Det kan ge stora prestationsfördelar, motsvarande cirka 30â40 watt extra pĂ„ cykeln eller möjlighet att hĂ„lla igĂ„ng ungefĂ€r en timme lĂ€ngre.
Huvudbudskapet; bra data om kroppssammansÀttning kan anvÀndas för att bÀttre planera trÀning, pacing och energiintag, och att kroppssammansÀttning pÄverkar prestation pÄ djupare sÀtt Àn bara hur mycket fett man har.
A right shift in the lactate curve can happen for two completely different reasons.
Reason 1 â Higher VO2 max Your aerobic system combusts more lactate. Less builds up. The curve shifts right. â Everyone wants this.
Reason 2 â Lower lactate production Your glycolytic system becomes less active. Less is produced. The curve also shifts right. â ïž Depends entirely on your sport.
Same curve. Opposite implications.
Sebastian Weber on why the direction of your curve tells you almost nothing without knowing which system caused it.

MÄnga labb och trÀnare anvÀnder laktattröskeltester för att följa utvecklingen hos sina idrottare. Testet genomförs genom att intensiteten ökas stegvis samtidigt som blodlaktat mÀts efter varje steg. Resultatet blir en laktatkurva dÀr intensitet (t.ex. watt eller hastighet) jÀmförs med blodets laktatnivÄ.
Kurvan visar hur laktatnivÄn förÀndras nÀr belastningen ökar. Detta pÄverkas frÀmst av:
1. Laktatproduktion via det anaeroba energisystemet
2. LaktatförbrÀnning via det aeroba energisystemet
3. KroppssammansĂ€ttning och kroppens förmĂ„ga att âspĂ€da utâ laktat.
NÀr intensiteten blir högre produceras laktat snabbare Àn kroppen hinner ta hand om det, vilket gör att nivÄerna stiger.
En förskjutning i laktatkurvan betyder dock inte automatiskt bÀttre eller sÀmre prestation. För att tolka förÀndringen rÀtt mÄste man förstÄ vilka fysiologiska faktorer som ligger bakom och sÀtta det i relation till idrottarens mÄl och behov. #enduralab #enduranceperformance #ironman
Your lactate number isn't just one thing.
It's the result of two systems working at the same time:
đŽ Lactate PRODUCTION â how much your glycolytic system generates đ” Lactate COMBUSTION â how much your aerobic system burns off
The concentration you measure at your earlobe? That's just the balance between those two.
This is why looking at a lactate curve without understanding what's underneath it is like reading a scoreboard without knowing the game.
Sebastian Weber explains the mechanism most coaches skip.
