People fail to remember that team sports training and correct form are 3 different things.
As somebody said you should never base correct form on a commercial. That being said, when you are with your peers getting amped up in the gym you will do stuff to motivate yourself, that was more his purpose in stomping.
Also, people always get mad at football players and basketball players for incorrect form in the squats and other lifts. Often times what is correct form for competition does minimal when compared to minor adjustments in form for sport.
It has been shown many times in studies and on the field that a partial squat has better on the field effects than a full “Ass to the Grass” squat. [/quote]
Jumping in the clean and jerk OR the snatch, is absolutely a great idea. However, don’t take it too far. One MUST jump when cleaning or snatching, its not an economy of motion issue, it’s an issue of getting the job done and correctly at that!
Jumping, and yes, stomping one’s feet into the platform helps in many ways. Virtually all elite lifters jump their feet, how else do they end up slightly wider than during the initial pull? Sure, everyone’s style is slightly different, but some commonalities do exist.
Oh yeah, as the weight gets heavier and heavier it will surely be more and more difficult to crisply move ones feet, but nevertheless, it should occur!
(don’t get me wrong, leaping into the air is not really necessary!)
Lastly, I’m actually really curious what kind of sources you have regarding partial squats being more applicable to on the field events over full squats. If you wouldn’t mind posting some of them, it would be interesting to read.
p.s. Here is a video of a GREAT lifter training…I’m pretty sure his feet move, both REALLY fast and really crisp.
