Re: MVC- induced short-term potentiation of explosive force

[Guest guest]

Tom -

Here at the US Olympic Training Center, I use near-

MVC's with several of my athletes prior to competition

and have been doing so for the past two years. The

results are well worth the effort the athlete expends

coming to the weight room early in the morning the

day of the competition.

[Much the same information has been discussed previously, with

plenty of references, under the heading of post-tetanic potentiation,

and pre-activity preparation, as well as in my " Supertraining "

textbook. I think that Charlie Francis also commented on the use of this

method by Ben many years ago. Do look through our archives.

We will perform a quick warm-up, touch the core and

then get on the platform. There we will do several

sets of high percentage partial pulls. We then go

into the rack and do several sets of maximal partial

squats with an emphasis of exploding up through the

bar. The athlete then leaves the weight room, heads

to the track and continues to stay warm with some

speed oriented plyos.

Their results in competition have been greatly

improved and sprint times are reduced. I will do this

training only with athletes whose sport requires a one

time max effort - luge, bobsled, and skeleton.
