Thank you America, thank you for your support, thank you for this visit. Thank you @POTUS, Congress, and the American people.
Ukraine needs just and lasting peace, and we are working exactly for that.

Draadje.

Waarom Europa moet breken met de Verenigde Staten, en moet stoppen met de hielen te likken van Trump. En als de VS de NAVO dan gaan opblazen, dan doen ze dat maar. Dit is een U-turn van jewelste van de VS. 1/?

Is training volume really the most important variable for maximizing capillary adaptations?​

Here is a breakdown from our meta-regression of 425 studies of how ET, HIT, and SIT affect capillarisation and why training volume becomes more important the fitter you get 🧵

Modelled changes in VO2max over time with different training interventions. Log-linear response

Haven't fully digested this entire behemoth meta yet (aggregating 353 studies & ~6000 participants!), but this might be my new favourite figure 👏

Training Truths: Aerobic Conditioning

What feels important

Focusing only on maximal aerobic speed (MAS) as the key to improving aerobic conditioning.

What actually moves the needle

Sequencing between critical speed, low-intensity training, and maximal aerobic speed.

Each has a role, but the true value comes from understanding how to blend them into a progressive structure that builds endurance repeat and recover durability.

MAS alone won’t create the complete athlete.

It’s about using the right tool at the right time in training.

The myth of switching to fat metabolism. Countless times I have heard commentators say “And then you switch to fat metabolism”. But how does fuel use actually work? Is there really a switch to fat metabolism? https://t.co/YmqmwPXJOd

Prior HEAVY exercise 🪨 promotes FASTER rise in VO2 ⬆️📈
during a FOLLOWING BOUT of exercise. 2️⃣🚴

We call this mechanism - a PRIMING EFFECT! ☝️1️⃣

Use the priming effect to
accelerate T to VO2max 🚄⏱️🫁
in your HIIT TRAINING 🚴🏃‍♀️🎯…

I won’t have time to read all the theories about tonight’s outcome. It’s also not really important because it was win or lose.

But here is what I know: Femke tried everything to run faster than ever to stand a chance to win gold.

Just the pace was too fast for her profile 24.04 at 200m / Sydney 23.84!). Therefore she didn’t run relaxed and economical enough. So she went out of fuel on the last 120m

But Sydney was just too strong tonight and by risking everything, Femke exposed herself and lost silver.

This is how competition works. If she would have race for second, she wouldn’t have been happy either.

Incredibly proud of her giving it all. How many athletes would have give the mixed relay a go in her position (remember that she produced an amazing 47.93 to win gold)?

So, no she didn’t have too many races before this final, she just tried everything to win and an amazing athlete was just better than her. And this strategy brings her bronze.

Thanks to all the fans in the stands. The stadium was mainly orange tonight. And this is because of Femke’s personality and her love for competing.

Big congrats to Sydney for continuously setting new standards and pushing us on the road to excellence.

Huge performance for Anna Cockrell becoming the 4th athlete in history running sub52.

De 400 meter horden is een van de zwaarste atletiekonderdelen. Femke Bol lijkt met gemak over de hindernissen te snellen. Wat is haar geheim?
