Bolt's 9.58 in Slow Motion

[James_Smith]

@sady

has anyone noticed he pauses before the first footstrike and he spends no effort on pedelling with the rear leg, instead he gets the foot to the position for the next power stroke.

This low recovery of the swing leg is a mechanically efficient movement given the horizontal force vector akin to start and early acceleration.

My curiosity is whether this came naturally to him and Powell or if it was instructed.
