To me it happens automatically... less time on the ground = faster speeds.
Are you sure? Speak with a hurdler and they'll say more time on the ground = faster speed. That's why they aim to spend as little time going over the hurdle as possible.
The explanation I always get is:
The more time you spend 'connected' to the ground the more time you have to exert a forward force. While in the air, you are losing speed due to wind resistance and you cannot speed up because you have no ground to create a forward force with.
I can see a point where too much time on the ground would be inefficient and detrimental to speed but minimizing ground contact would eliminate a lot of positive force that could potentially be created. Like a lot of other things in pole vault I think a fine balance must be struck.
