I think you know the deal here: Fogelson doesn’t know anything, and just attacks other people (see Goose, and well as people other than LKH in this thread) to make himself look good.
From what I see in this thread, LKH didn’t post anything claimed to be from Shaver; The Shaver training that was posted was contained in a link (now dead) posted by Tamfb, and LKH linked some information from a Speed Dynamics video by Loren Seagrave (you can’t argue that it’s in there or that it’s from Loren). There’s more about contrast (at LSU) in the old Richard Thompson thread, which others have pointed out. I also found this comment about contrast training from Mike Young:
I’ve done something similar and found it can work quite well. I actually just prefer sticking to acceleration with this method if you’re going to use it as a contrast because acceleration and maximal velocity are so different in technique and physical demand that it’s basically like doing two different activities. If you wanted to do some version of this though in one clean quick format you could use a releaser belt that releases tension at 20m (or wherever you want) so that you are resisted through acceleration and then can fly at top end.
Fogelson, actual training snippets from LSU containing contrast traning has been posted twice on this forum. You have claimed knowledge about Shaver’s training a number of times that what is claimed is wrong. But YOU have actually produced nothing. If you have something REAL, post it. Otherwise, I have to conclude that you’re just a bullshitter who belongs on everyone’s ignore list.
