In weightlifting, whenever a lifter applies the deficit method, he does so with the intention of either increasing power at a particular point of the lift and/or minimising or eliminating a weak link in the lift.
A point some of you may find very interesting, and something which have personally experienced back in 1983, was that at times, lifting from a deficit position, one can actually lift more, albeit slightly more! How can that be or why does that occur you may be wondering, especially when one has just lost some crucial power generating distance (say from the floor to the knees).
This phenomenon occurs under one condition and one condition only as far as I know and have experienced first-hand.
A) How it occurs? It occurs when your lift is done from a hanging position.
B) Why, what is so significant about the position being from the hang as opposed to the load being “rested” on something (to create a deficit). It has something (I can not prove), and that something is muscle under tension (or contraction). In other words, if a muscle is already under tension, it seems to generate more force, explosiveness, with muscles that are in a “primed” state, ready for serious action in a blink of an eye lid. How would that relate to what this thread is about and to Karen’s initial post? I’m not 100% sure, but a discussion to find a way to perform a dead lift from a very slight hang position may be in order here.
Fadi.
