One area that I think is overlook in this debate is the fiber types.
It has been established that over time you can change your ratio of Slow(type I) Fast (IIa) Super-fast (IIx) muscle fibers. Now look at the relationship to speed work is in regards to the respective lifts.
I look at this question with a question.
If you have a sprinter who's training is limited to just one type of resistance training. Is this perceived optimum training covering all facets necessary to this individual to make him faster more explosive.
I think we will find optimum training varies to the individual thus why the strong beliefs on both sides of this theory.
Speed wk is the nearest equivalent to poly work. In respect to fiber types some people already have a better ratio of IIa & IIx fiber type thus see less benefit to speed training hence the divided consensus.
