This podcast is with Michael Dugina, who is the Strength and Conditioning Co-ordinator at Collingwood Football Club in the Australian Football League. His story is inspirational. He started at the club as the Boxing Coach in 1994.…https://t.co/J6547hISZA https://t.co/DRinGMR9eY

VO₂max is not the whole story.

I’ve been showing this slide for the last 15 years.
Same athlete, 2 years apart.
VO₂max? Essentially unchanged.
Performance? From average to one of the best.
What changed was lactate!.

VO₂max reflects cardiorespiratory adaptations to exercise, the size of the engine: heart, lungs, and oxygen delivery.
Lactate reflects how efficiently that engine runs: mitochondrial function, cellular metabolism, substrate utilization, and metabolic flexibility.

At the same workload, markedly lower lactate indicates greater mitochondrial efficiency and improved lactate clearance capacity. In other words, better metabolism.

In elite sport, we’ve known for decades that VO₂max does not discriminate among top performers. Many athletes share similar VO₂max values, yet those with superior mitochondrial function are the ones who win. That difference is metabolic efficiency, and we assess it through lactate testing, not VO₂max testing.

Suddenly VO₂max is being crowned as the gold standard for longevity. But metabolic health is one of the main focuses of longevity. If that is the case, the most meaningful marker should also be metabolic and Lactate provides a more precise window into mitochondrial function. Furthermore, unlike VO₂max, Lactate allows us to individualize and prescribe exercise with accuracy, something we’ve been doing with athletes for decades

@rohan_connolly @StuCormack Ok cool. Yeh no idea. Been overseas 5 years. My observations are more long term repercussions. AFL draft is weird. So young. Need to stockpile kids when hit rock bottom & hang in there 5/10 years. Kids teams won’t win flags. Odd system. Versus being up there and tweaking on run.

@rohan_connolly @StuCormack I was there 1987-1998. Different era. But I do not think the club has recovered since ASADA affair. Why? History seems to point to fact that an error like that in the closed AFL draft (versus open EPL) for example. Can take over a decade to recover from. Call it bad decisions.

[Loris Bertolacci @LorisBertolacci]

@rohan_connolly @StuCormack Haha not delusional. My opinion mate was that “ASADA” list was ready to boom. My opinion. Like arseholes. Everyone has one. After that saga yes cot case. But maybe history needs to point the figure at people who dismantled that club. After that chasing their tail. No “brand”.

@JonathanHorn23 Bit off the mark with 2006 @jonathonHorn23 . Story sounds good. But underpinning factors way off.

MAS is an intensity measure for conditioning prescription. It is not a HIIT session @NE_Heaney https://t.co/yADIJskGGe via @SportsmithHQ

Rush posts dosing speed MD-2. Thought adaptation to eccentric exercise > 36 hours? Priming I get. And get the link between RBE and adaptation to eccentric exercise. Interesting how this review says “significant gap” w eccentric exercise adaptations.

The (relative) importance of training volume and intensity: why there are no shortcuts in endurance sports?

A Trump supporter was seated next to an older woman on an airplane and he turned to her and said, “Do you want to talk? Flights go quicker if you strike up a conversation with your fellow passenger.”

The old woman, who had just started to read her book, replied to the total stranger:

“What would you want to talk about?”

“Oh, I don’t know,” said the man. “How about how they stole the election in 2020 and Donald Trump should be president.”

“Okay,” she said. “Those could be interesting topics but let me ask you a question first. A horse, a cow, and a deer all eat the same stuff – grass. Yet a deer excretes little pellets, while a cow turns out a flat patty, but a horse produces clumps. Why do you suppose that is?”

The man, visibly surprised by the old woman’s, thinks about it and says, “Hmmm, I have no idea.”

To which the old woman replies, “Do you really feel qualified to discuss politics, when you don’t know shit?”

Note 1500m runner Jye Edwards, 20cm airborne before one of >2000 multiple-bodywt plyometric footstrike forces through the Achilles in a track session. It's worth considering the risk/benefit ratio before adding plyometic stress to the Achilles in a middle-distance gym program.

The amount of rest you prescribe in workouts, can hugely change the type of training stimulus received.

Be deliberate with your choices.
