What actually relates to speed? 👇
We’ve tested 40+ athletes across 50+ individual tests.
Now we’re starting to look beyond individual test scores.
We’re asking:
What actually relates to speed performance?
And the early data is interesting.
📊 10m Acceleration ↔ Flying 20m: 0.89
A very strong relationship in our current dataset.
🧠 Movement IQ ↔ Projection: 0.76
Interesting questions around how movement quality and projection interact.
🦘 CMJ ↔ RSI: 0.68
Jumping performance and reactive qualities aren’t completely independent.
⚡ 5m Reactivity ↔ 10m/Flying 20m: ~0.50
Reactive qualities appear to have a relationship with sprint performance — but clearly don’t explain everything.
And then there are the weaker relationships.
That’s arguably where it gets really interesting.
Because speed isn’t one quality.
It’s not:
“They’re slow → make them stronger.”
Or:
“Their acceleration is poor → give them acceleration drills.”
The better question is:
What is actually limiting this athlete’s movement?
Force?
Stiffness?
Timing?
Rhythm?
Projection?
Reactive qualities?
Perception-action?
And then:
Can we change the problem and see the performance change?
This is only our current dataset. Correlation doesn’t prove causation.
But that’s exactly why we’re collecting the data.
Stop guessing. Start testing. Start questioning.
