Siff was actually a buddy of mine.
Other than the skyscraper example, do you see any other analogy between a beam and a muscle? Would you consider it a model for muscular physiology?
How does metal fatigue? Can you tell a fatigued piece of metal from a “fresh” one?
What does “inssues” mean?
What is moving, the body, the body part or the force? What difference does it make (static vs dynamic) at “particulate level”?
What does “weight” have to do with the breaking point (both in america and outside of it)?
Does the cologen have to do with the final tract of the digestive system?
In your opinion, do antagonist muscle groups express forces acting upon a joint or directly on the agonist muscle?
Would you suggest a construction worker walking on a beam (or a muscle, j/k) to rely on the “good” feedforward only? Same question for a gymnast.
How did you get the figure of 99.99999%?
Do the athletes not display the ability to reduce antagonist activity all the time or just sometime? How do you explain sudden injuries by the fastest athletes (supposedly those more able to do the above)?
If 99.999999% of the athletes are not able to shut down the antagonists in ballistic actions, why, IYO, the 100m at the Olympics is not turned into a survivor kind of game?
How would you address the above mentioned ability?
If there is a limitless ability to increase performance, can I be a 100m Olympic finalist in Beijing?
