Yes but a human body/muscle tendon unit isn't some basic 1+1 shit, there's optimal oscillation, hysteresis of tendons, stiffness/compliance of the SEC, muscle pennation, relative muscle insertion, relative lever length, fibre composition, fibre length, neural inhibitory mechanisms, neural learning for optimal damping of vibrations etc. Anybody who claims that they know what's what is full of shit, nobody knows all the factors behind plyometric trainings effectiveness for example. There is more and more research being done and while we still don't know much for sure we have a far better idea than anyone did even 10 years ago. Most S+C coaches are useless but they still are nowhere near as useless as the average boxing trainer is when it comes to understanding the human body.
