I looked several times about this topic on Google, but so far without much success.
I'd like to know the speed (or run distance) over the time for a sprinting human ; example : 5m/s after 0.5 second, 8m/s after 1 second for speed, or 2.5m after 0.5s, 6m after 1s for distance.
It could be from a 60 or 100 or 200 or 400-meter sprinter, or even better from a tennis man holding his racket. Any of these would give me some precious info..!
So if by chance you know where I could find this kind of data, please post here !
