Pending any clarification from JHuffman, I think this series of posts has been enough to definitively answer the question from the start of this thread.So, starting off in a jumbled chronological order:
I thought JimFiore went through seeking clarification on the difference between Ground Reaction Force and Recoil?
Regardless, I would think it would be straightforward to measure. We've previously seen links to force plate charts from which it is easy to see there are two peaks. The first peak is the maximum force exerted on landing (which is then partially or wholly stored up in the muscles, etc).
The second peak is the maximum force exerted on 'push-off'. If this second peak is less than the first, then it is difficult to say whether it is comprised solely of muscle recoil or includes some conscious effort.
But if the second peak is larger than the first, then that absolutely proves there was a further addition of energy to the system. Since no one has yet been able to produce energy from nothing (ie you absorb amount X and exert amount X + Y), we can definitively say there has been additional push-off.
I believe the links were provided by Alex S and they did show higher second peaks. I don't know if these were from POSERs or not, but it would be interesting to see such charts from someone running POSE.
Here, stated in very clear terms that no one can dispute, you are saying that not only is the body a lossless system (such that everything absorbed from landing due to gravity gets transferred 100% back on recoil), but that the human body is a free energy producer.
You are stating that we take the gravitational potential energy from an initial height, transfer it to kinetic energy through falling, transfer it to elastic potential energy in the muscles and tissues on landing, and then transfer it back to kinetic energy on recoil to drive us in the vertical direction so we regain all our original gravitational potential energy. Plus we have energy left over to drive the body through a horizontal distance.
There is no ambiguity or misunderstanding in what you stated (since it was stated very clearly and concisely). You repeat the same belief several times in subsequent posts (see below for specific references).
But the problem is that the human body is not a lossless system and no one has ever come close to generating free energy, hence your statements are as fundamentally wrong as saying 2 + 2 = 1.
More statements of the human body being a lossless system and producer of free energy:
However, your last post says:
This is in contradiction to what you very clearly and repeatedly stated above. If gravity is NOT enough to continually drive the system, then you are saying there is additionaly energy added. You said there is NONE since everything absorbed on landing gets transferred back to regain lost height and propel forward.
So do we need to consciously push-off since gravity is NOT enough to drive the system? Or do we need to just let the muscles recoil after being loaded up by gravity and not do any further pushing?
You can't say one thing (no pushing) and then turn around and say you need to add more energy to the system to keep it going.
I think I've covered this above. You have very clearly stated your belief that POSE professes the human body to be a lossless system and capable of generating free energy.
NO ONE, not even Dr R, has provided any study or evidence or proof that such things are even possible for any system in the real world, let alone something as complex as the human body.
Maybe you've misunderstood and JHuffman or one of the other experts from the POSE website who are following this thread can come on to say that your two numbered points above are wrong and that you've misrepresented POSE.
But since there appears to have been little disagreement over the last few pages between what you and JHuffman have stated in answer to specific questions, I'm assuming that your explanation of what POSE says accurately reflects what POSE believes.
So, since it is now established explicitly that POSE believes in a lossless human body capable of generating free energy, I think it is safe to absolutely answer the original thread question with:
Yes, POSE is crazy.
