Hier wird eine Argumentation geliefert, warum die Kicks in Rückenlage die schnellsten sind: http://coachrickswimming.com/2014/02...water-kicking/

"So if kick symmetry is important, then kicking on your back should be the fastest (if we ignore depth) as gravity helps to balance out the muscle strength disparity. The stronger forward kick works against gravity, while the weaker backward kicks works with gravity.

There is one other phenomena contributing to faster kicking on your back. Our spines form the structural basis for the torso, and when in the water our torso basically hangs off the spine. So when we’re on our back, the soft tissues in our torso are resting on the spine. This results in little sagging caused by gravity. However, when we’re on our fronts, the soft tissues in our torso now hang down off our spine. Training, and especially core training, can help minimize that sag, but some amount will still be there. So kicking on our backs should naturally provide a better streamline, resulting in faster speed."
