For that to be the case, then there would have to be a fundamental physical reason, a matter of undesirable body mechanics that it would be physically impossible to prevent. Without necessarily denying that this is so, I'd like to ask you what you believe this reason to be? The momentum commitment(s) that paulb describes or something similar?
You're right! And there is.
Power comes from hip rotation. Hip rotation comes from pushing off the ground. You push off the ground with your back foot (and your front foot too, to a lesser extent.) When you pivot, or raise your heel, you are not pushing as effectively.
Thank you! I appreciate the response.
I definitely agree that you aren't going to push off the back foot as efficiently or powerfully with the heel raised. However, I can only agree that it's "always wrong" if that particular aspect of effectiveness is your sole (or perhaps just primary) consideration. For me, anyway, it isn't.
A very important component of my fighting style is mobility. I am in more-or-less constant motion (from a footwork standpoint) when I fight, attempting to use control of measure to my advantage. I find I am more easily able to change direction quickly if I am on the balls of my feet a fair part of the time. It buys me a sometimes invaluable fraction of a second in tempo advantage. I have obviously had to put a fair bit of work over the years into refining my footwork (etc...) to be able to employ proper hip rotation while throwing shots in motion. It is unquestionably less efficient than throwing from a heel-down stance...but keeping my heel down too much is
also less efficient from a footwork (and thus control-of-measure) standpoint.
So I guess the point I'm making is that it's a trade-off...as are so many other aspects of armored combat. In this case, you have to balance the efficiency of both the shot and your footwork, and these factors are somewhat at cross purposes here. I am willing to (slightly) compromise shot efficiency in favor of being (slightly) faster on my feet, because I can already throw harder than would be considered necessary or even acceptable from a heel-raised stance, as long as I don't let other aspects of my body mechanics slip.
In part, this is because I have very strong legs (former velodrome match sprinter...my calves only recently dropped under 20" since I quit racing) and can get a pretty strong push off the ground with a raised heel,
and I've learned how to get decent hip rotation while on the move. Someone with a different body and/or training focus might well be advised to do their best to keep their heel down. A big, hulking fighter with enormous upper body strength might be advised push the trade-off even further towards the mobility side because they can get away with using mostly arm strength for their shots (but desperately need to do something about being too slow-footed).
I think I'm not objecting to your assertion about shot efficiency (the body mechanics involved are pretty cut-and-dried), only to the absolute claim that heel-raising is
always wrong.
