For forward approach vaults the best men in the world (e.g. Dragalescu) peak at over 10m / sec velocity.
But the important velocity is on contact with the board.
Here’s one (predictable) finding from a recently published study …
Mean values of individual step velocity for top class and middle class gymnasts.
Just like my coach told me in the 1970s: “start your run slowly and accelerate as much as possible to the board“.
That study has much more though the sample size is small.
That’s from the most recent Science of Gymnastics journal.
Update – See discussion on this topic on Chalk Bucket.
