correct and what happens is the opposite of bouncy. Slower runners have more vertical movement up and down than elite level ones. When the hips are high and running at top speed the hamstrings and quads are not in conflict and are working as one due to the force coming from the hip like a pendulum. This can only be achieved with adequate hip height and is called Lombard’s paradox.
Also worth remembering CF described it as trying to make a wheel go fast, you actually achieve it best by skimming it with minimal contact as opposed to conscious push / pull, same with sprinting.
Nice analogy. I’ll have to try that with a new athlete of mine who runs with low hips and heavy feet. She’s been doing it for years and I’ve been having trouble breaking the habit. She’s been getting better during practice, but reverts back to her ‘normal’ stride pattern in races.
the “bouncy” feeling you are discussing isa great feeling to have but i wouldn’t force it. with proper forces through the ground this will happen natural as its a rebound effect of the forces in which you are placing.
Totally agreed. Though I have also experianced the bouncing/bounding at below top speeds. What Carl lewis looks like in slow motion replay on the long jump run-way. It sorta looks how I ‘feel’ in warm up strides.
I’m not trying to lift the knee that high or have such hip hieght. The ‘bounce’ of the rear foot feels great. But as you say, it is the result of other things.
