Someone should be teaching a course on training for strength, sport and fitness using Supertraining as the only course text. It would be a year long course,at least. Even now reading through it again it is daunting.
The density of information is not to be believed.
Name a topic or aspect of athletic,fitness or rehab training and Siff has thought about it, analyzed it, corrected it and wrote about it! From the physics,biomechanics,physiological and neurobiological aspect of sport and training Siff was into it at the highest levels.
" The sequence of recruitment of muscle fibers by exercise also has important consequences for training. The ST( type 1) fibers are recruited first for muscle tensions up to about 25 %, the FTa( type 2a) are recruited next and the FT ( FF or Type 2x) fibers last, as the intensity of the activity increases towards a maximum or as the ST fibers becomes seriously energy depleted. Thereforeif the intention is to train FT fibers for a particular sport, it is vital that high intensity training be concentrated upon.
Further research reveals that this high intensity is not necessarily dependent on on the use of 1 RM( 1 repetition maximum) or near 1 RM loads, but the degree to which the relevant muscle fibers are recruited during the effort.In this resepct, the terms fast twitch and slow twitch do not necessarly mean that fast movements recruit exclusively FT fiber and slow movements ST fibers.To analyze the involvement of different fiber types, it is vital to determind the force that needs to be produced. If large acceleration of the load is involved, Newton's Second Law of Motion decrees that the resulting force will be large. Thus, the maximal force generated from the rapid accleleration of a 100 kg bench press easily can exceed the maximal foce produced during a slowly accelerated 150 kg bench press.
Both a small load accelerated rapidly and a heavy load accelerated slowly strongly involve the FT fibers.Likewise,expsolsive movements rely heavily on the action of FT fibers."

No wonder Louie and Dr Siff got along so well.
