The aerobic vs anaerobic model is not wrong because it’s simple. It’s wrong because it implies a switch where there is only a continuum.
Glycolysis is always active. Lactate is always produced and cleared. Mitochondria are always involved. There is no moment where the body “switches” from one system to another. What changes is the balance between glycolytic flux and mitochondrial capacity and lactate is the best real-time proxy of that balance.
I proposed in 2013 a model based on substrate utilization. Now I propose an update of that model built around four metabolic states. From metabolic equilibrium at Zone 2 all the way to metabolic overload, where the central question is not what fuel you’re burning, but whether the system can sustain balance.
Ultimately, the ceiling of equilibrium matters more than the ceiling of oxygen consumption.

@_RobinD Det är möjligt att du skadat menisken på insidan av knät. Korsband osannolikt. Jag skulle säga att så länge knät inte svullnat upp skulle jag åkt skidor ändå. Kör något knäskydd om du har eller tejpa knät när du ska åka. Sök upp rehabpersonal som kan göra en bedömning.
Suicide.
I'm choosing to be deliberately blunt and provocative in this post because it's necessary. Government, charities, football clubs are all pushing water up a hill in highlighting what is undoubtedly a major health crisis.
You take a rope.
You put it up in a garage or a tree nearby or far away.
You're thinking about every loved one you'll leave behind as you put that rope around your neck.
Then you drop.
Some are decapitated.
Some aren't.
All are found by someone who has a lifetime of trauma that will never leave them.
A son.
A daughter.
A brother.
A sister.
A mother.
A father.
I know 2 men who hung themselves.
One was found by his Mom.
One was found by his brother.
Neither have recovered fully. 20 and 30 years on.
A life sentence for people who were already worrying, terrified their loved one may do something.
So just visualise the above and ask, "is there another way"?
A segway for a moment.
I do a few Q&A's every year. Tales of yesterday with a 99% male audience of my age group.
After the stories and fun, my last question back to the audience is..
"Hands up if you struggle with a mental health issue".
Nobody ever puts a hand up. Despite 1 in every 3 of 500 attendees statistically struggling.
"Ah, nobody, that's fucking brilliant! Well I do! ". I then graphically tell people, stunned into silence about how a rope around my neck in the middle of nowhere jolted me to go home and cry like a baby to my Mom.
After the Q&A has finished, something always happens. I'll be chatting to a few guys, saying bye and one by one, men will come over and whisper " I struggle".
Or my mailbox the next day will have 30 emails from guys, their partners or kids saying " Dad/Uncle /Brother was there last night and what you said hit them hard".
And that's how some people realise that it's time to speak to a pal or family member or even rant to me in an email. It works, I often get a follow up email a year or 6 later saying that they took responsibility for their suicidal feelings and are now flying.
Humans are programmed to want to live, to have families and to keep the species growing and thriving. So for a human to want to short circuit that desire isn't normal, and it should never be spoken of as normal. It's the ultimate red flag.
If you suspect your mate, Dad, Brother, Uncle is struggling mentally, they deserve your intervention.
They deserve a " are you OK, please tell me what's up".
They deserve an opportunity to get past wanting to hang a rope over a tree or in a garage and slowly struggle until they die and you find them.
If you've been there and trust me I have plenty, then you'll know that text out of the blue, or a footie mate or one of your kids asking jow you are can open the curtains to some sunshine.
Because when suicide is your only answer, the room is already dark, and you can't see a way out.
So please, fucking pretty please, ask that husband, Dad, Uncle, Cousin, footie pal TODAY how they are.
You may be shocked what comes back but extremely glad that you asked.
For those who struggle, you're not alone.
1/9 Du jobbar hela livet, betalar skatt och tror att du säkrat din ålderdom. Men när du går i pension får du knappt mer i plånboken än någon som aldrig jobbat en timme. Det låter otroligt. Men det är exakt så det ser ut i Sverige 2025. 🧵En tråd om det väldigt orimliga systemet
Sommaren närmar sig och vad passar bättre än att lotta ut ett par fiskedrag? De är en gåva från @TINfonder (2 vinnare.)
För att vara med i utlottning:
Följ @Aktiepappa och retweeta detta inlägg!
Nu finns ny bok av @don_crisse ute i handeln om Warren Buffetts fantastiska investerarfilosofie och historia beskriven på ett personligt sätt. Jag har skrivit förordet och retwitta så lottar jag ut några x: https://t.co/K0cWIHPcyu
@HappyZubi@JacobStjernberg@Krazikatt Systemet är långsamt, nästintill omöjligt att söka i och trots att det är ett gammalt system finns det fortfarande många buggar. UI känns som hämtat från början av 2000-talet. Möjligt att det finns nyare versioner som är bättre som jag inte har tillgång till.
