One note about Stephen's exerpt though, the HPC does NOT incorporate a full front squat. The power version is caught at around a 1/4 o 1/2 squat. Tim
I'll admit that I use "clean" and "power clean" interchangably when there are differences between the two:
The "clean" is called the clean because in the OLD DAYS, the bar was not ALLOWED to contact any part of the body before it reached the shoulders. It had to be lifted "clean" of the body vs. the continental or anyhow lifts which could touch the body. Sometime, I don't recall when, the rules were changed to allow the bar to contact the thighs, shins, etc. which brought in modern technique. It also de-emphasized the relative importance of upper body as compared to lower body strength.
The only "definitional difference" if you know what I mean, between the clean and the power clean is the following.
In the clean, more properly called the SQUAT or SPLIT clean (depending on version), the bar is caught on the shoulders and the lifter can amortize the force by riding the weight down, as far as he wants to go (w/o the ass touching the ground which is illegal).
In a power clean, the bar is caught high enough, and/or the amortization is short enough, such that the femurs don't get below parallel in relation to
the ground (or they have to stay a bit higher depending on how loosely one defines the power clean). This is the "power" position of the body, knees bent in a pre-jumping position, and that is where the lift got it's name.
True or false? It would seem that the power clean involves upper body pulling more, while the full clean relies more on the legs to drop under the bar.
