What is being judged is ability to do work. W=F(d)=mgd. Mass of barbell, gravity and distance of the concentric movement, what other factors are in play? Do you have a better definition of strength?
I’ve never been to a competition where the distance the bar traveled was measured, and was a factor in the competition.
exactly, according to this moron, the taller O-lifter should win even if his total is a kilo or two less than the other guy. idiocy
I will try again. Powerlifters tend to move heavy weights short distances in training and in competitions. In fact, powerlifting technique is all about reducing the distance the bar needs to move while meeting the necessary (and highly variable) criteria.
We have one lift to compare weightlifters and powerlifters with any meaning, the squat, which I think we can all agree is an excellent demonstration of strength.
Weightlifters train the squat deep in order to enhance their recovery from the catch.
If we consider two athletes of the same height and ranking in their respective sports, a PL and a WL, doing max squats. We will see without any ambiguity that the WL moves the bar a greater distance any where from 2-3X depending on the styles compared. If they where lifting the same weight and you had to judge which one would you say was stronger?
Now of course the max weight of the PL might be higher, but how much higher? Can we compare raw squat to raw squat? Does the PL move 2-3X the weight in the raw squat? I doubt it. That is the use of the equation for work. It takes in consideration both variables mass and distance and the constant gravity.
again, I dispute the use of the physics equation of “work” as being interchangable with “strength”
oh, and by the way splicer, Force DOES NOT equal mass times gravity unless we are talking about a falling object. You just gave the equation for an object’s WEIGHT on the planet earth. You know exactly enough to be dangerous, and nothing more
This is sad considering you are calling me a moron. The force produced by a barbell is indeed equal to mg. Of course, I am giving the equation for weight. If you stop to consider why this might be relevant to a discussion about people moving weights it might help.
the acceleration of the bar will only be equal to gravity if the barbell is FALLING tho. If someone squats 500 lbs in 2 seconds and someone else squats it in 4 seconds, they have not applied an equal amount of force to the bar, the acceleration of the 2 second squatter was greater.
As I said in my response to SWR-1240, my misnaming of the sport/idiots comment was straight up ball-busting. If you and him want to make this personal by calling me a moron, that is fine. Enjoy you internet bravado.
my internet sarcasm detector must be on the fritz today. personal comments withdrawn[/quote]
By reading your quote of splicer, I noticed he mentioned the name calling (I didn’t see it in his post, because he’s already proven his posts to be a waste of time to read).
As far as the name calling, I called you (splicer) a moron, not only because of your ignorance, but also because you first insulted the whole sport of powerlifting and everyone who competes in it with your comment:
“…they are idiots who incorrectly named their sport.”
Or did you conveniently forget that you said that without instigation?
I guess this is a rhetorical question since I will not be reading your response, but I know you’ll be reading mine.
