Reply To: Roadblocks to Adoption
There is some work from H.M.Toussaint & K. Vervoorn and a system they developed (MAD) that did have some promise. It’s built along the lines of a power rack. But not the same. I can’t find the original study (I have it just can’t seem to locate it).
Kinda funny because the first attached abstract came from Rushall’s website.
The second attached review is from Dr. Mullen and doesn’t’ specifically talk about use of power racks. But what he does discuss can be said for them and also for anything that you tie to a swimmer.
With that said. I’m not total againist them (the old ones with plate weights because you can determine 1RM) The ones you fill with water are just about useless as all I’ve seen is coaches/swimmers fill them with an unknow amount of water and swim. Maybe it would be better to say HOW they are used is useless. If you know anything about development of power (F x D /T) then you know that opening the testosterone valve and pulling the thing to the other of the pool ain’t it. It is weight training and needs to be controlled and from what I’ve seen with programs is the lack of perimeters using it and lack of gathered data. i.e. wt. used, timed, distance traveled at race tempos and cycles. Cyles are critical, just as in wt. training shorten the length and you will actually lose power development. So if they shorten the stroke to achieve the max amount of weight. Then you may not be working on what you think. (Just about every study states the loss of d/S)
Years ago we used them VERY time consuming gathering data on 4 to 5 kids that may truly need them 3 times a week and with one coach it becomes a nightmare. I may still have the data but it could take awhile to find it.
my 2 cents
