The ability to call someone "Wimp" is definitely part of the XF draw. How else can you be 6'2" and 164 lbs and call someone a wimp?

Funnily enough it's the same reason I whore out my arse to upwards of fifteen truck drivers a night at the M6 service station outside Penrith. Well, that and money.

You can't take fifteen big ones up the shitter? What are you? A fucking gayer or something? 'Oooh it hurts my ring'. Get over it soft-lad.

It sounds like they might have worked together.

I'd like to see a MMA fight between an xfitter and some other elite system representative, for example the CST (or is that elite?). After that, on the same day, a competition featuring a selected workout from each system. Then we would know who's TRULY elite.

Yes acceleration does matter because:

Work = Force x Distance

Force = Mass x Acceleration.

if you change the Acceleration portion of that equation than the Force will be different which would make the Work also different.

Bzzzzzzzzzt!!

'Scuse me while I whip out my calculus...

Work = the dot product of force with the direction of motion integrated over the whole path. With a constant force (and ONLY a constant force) that points along the path (and ONLY if it points directly along the path) it is equal to Force x Distance. Physics with training wheels. That ain't the case here.

But we are in luck. Because the work done on an object is also equal to the change in it's kinetic and potential energy. Since the pulluper is motionless at the bottom and top (even if only for a moment) the work is just equal to the change in potential energy, which is roughly...

Work_of_pullup = Weight_of_your_fat_ass X length_of_your_arms

Once again, you can only apply classical physics to biomechanics in the most rudimentary way.

You can measure gross forces, true, but whether you should waste your time doing it is very questionable.

Nafod,

Let's talk about how none of this eqauls Work because there isn't any displacement.

Actually, my point was I am not really caring about the particulars of the forces. You're right, going down that path leads into all kinds of difficulties with biomechanics. But measuring work and power versus VO2...there is a large body of research that shows you can relate them. Most of these focus on aerobic power, but still the relations apply, and the relations are based on simple, classical physics. To requote Ross's quote

Below the level at which a sustained increase in [lactate]b was observed pulmonary VO2 showed a linear relationship with power output; at high power outputs, however, there was an additional increase in VO2 above that expected from the extrapolation of that linear relationship, leading to a positive curvilinear VO2-power output relationship

What is interesting is researchers are just now starting to model non-constant power output work, i.e., interval training. It would be interesting research to see if the average power output in a high rep oly lift series directly correlates with VO2 also. I don't see any reason why it shouldn't.

Jason, you raise a valid point about the total work done in a cycle. I don't know the answer other than that I know muscles can't store or recoup the energy available on the way down. So just drop off the bar and reset each rep, same as dropping a barbell after each rep. That removes the issue.

do any of you faggots ever put the physics textbook down long enough to train?

I've found this physics discussion very interesting but I also assumed those involved were capable of doing one-armed pullups while holding said physics textbook in the free hand.

it's official - this thread has lost its momentum. Too bad - it was fun while it lasted.

I don't have any real opinion pro or con re: crossfit (well, I do think they are misguided in their "train to do everything at once" philosophy, and I think most of their proponents are going to be hurting cowpokes by the time they reach 40+ (years old, that is) but so what ?

I'll just hijack this thread and wish all you fucktards a happy post-Thanksgiving Friday.

I thought you would understand this is Taoist thread. It does not proceed in a linear fashion but ebbs and flows like nature itself. Like nature, Couch's rage will rise up and thrust upon us another revelation; kettlebells don't build power, kipping pullups are exactly 2x as good as regular, and such. At such time as the Tao requires the thread will swell once again like the ocean.

Peace

The HIV has got Glassman down right now.
The meds are smacking that out on the floor.
No worries, NAFOD the Dilrod is taking over for Glassman, he's just got to find himself a fairy to pass him the bug, & he's set.
