What about running FASTER? Do these improvements contribute to faster running potential?
The answer is a resounding YES. And here’s why: ENERGY LEAK.
Every added degree of “lateral pelvic drop” of the hips and trunk – as each foot makes contact with the ground – results in energy being lost – being dissipated.
Picture a radio tower.* It has guy wires around it on 3 sides for support.* If you remove the guy wires from one side, eventually the structure will collapse.* The joints in the body are no different.* They must be supported by the muscles.* Weakness or poor muscle activation puts excessive loads on bones, joints, ligaments and connective tissues that not ONLY lead to injury – it leads to lost speed potential.
To understand this even better, think of an analogy of a bouncy ball.
If I take that ball and throw it to the ground – the harder I throw it, the faster that ball comes back at me, and the higher into the air it would go.
But what if the ball had less air in it so that it “flattened” more as it made contact with the ground?
Your body is, in many respects, the same way. It’s analogous to your hip dropping to one side, as though your pelvis and hips were “flattening.”
