So the part about contractile changes didnt actually address the issue of cross bridging at all – it still stands that the faster you move the less cross bridges form. That is not my opinion, its the opinion of the gent who discovered and explained the actin and mysoin relationships. The article you cited has nothing to do with cross bridge formation, it merely pays it passing comment in a discussion about power production.
I am not sure we are actually disagreeing on the speed of movement issue. The intent to move a snatch quickly even though relatively speaking it moves slowly, has the same CNS excitation as the attempt to move a squat quickly.
And if RFD and power output is the issue – then isometrics can train both as effectively as plyometrics without all the hassle an extra skills.
I am uncertain as to your point about the SAID principle. My point about it is; why spend time in the training learning and adapting specifically to more metabolic and learning skills that are unrelated to the sports skill than needed i.e. jumps, throws, OL etc when other far less taxing methods offer the same effect at a less severe cost to the body and the athlete.
I am not aware of who Barry Ross is but I gather you don’t like discussing things with him, which is a shame as this has become a very useful thread and could continue to be.
