Does this mean my girlfriend can't use the "I'm too tired" excuse no more?

This is why, if you can browbeat your body into believing you're going to keep going, it'll eventually stop complaining.

This is why I can go for hours on an elliptical machine. I mean, I can, but I choose not to. It's boring. And difficult to read on.

Hey, even a broken clock is right twice a day!

So is this link all in my head too? Cause I can't see nuttin'
 
2004-07-29 04:34:10 PM
I think it's farked after 233 clicks. Does someone have a cached copy? I'd really like to read this; it might help me motivate my TKD students. :)

Is this why stupid guys are so strong?
 
2004-07-29 04:35:08 PM
farked already :(

You know, as an athlete, I have noticed the psychological effect. Some people are able to turn the 'pain' of lactic acid off with their endorphins. Personally, it's better to get real baked and then you just forget about it.

/trust me it works
//now watch this shot

All my PE coach ever said to me was "this is our little secret, Ricky, and if you ever tell anybody about it it would make me very, very sad. So said that I will destroy you and everything you love."
 
2004-07-29 04:36:48 PM
"Hitting the wall" is also all in your head...but in a different way...

/can't rtfa, it's farked
 
2004-07-29 04:38:22 PM
I guess the site has muscle fatigue
 
2004-07-29 04:39:12 PM
God damn "rebounder" test!!!! ARRRGGGHHHHH!!!!!
Do you all know what I speak of?
 
2004-07-29 04:40:07 PM
Farked in record time?

2004-07-29 04:41:12 PM
Some kind of mini-trampoline?
 
2004-07-29 04:41:14 PM
Yeah guys... And that refractory period is all in your head, too!
 
2004-07-29 04:41:18 PM
I'll keep this mind next time my hand cramps up after surfing pr0n for 4 hours straight.
 
2004-07-29 04:42:16 PM
can somebody click "back" and cut n paste their buffer here for us.

thanx

BULLshiatE! I once ran the NYC Marathon and I know what muscle fatigue is. Also, have any of you seen footage of the woman finishing the Ironman Triathalon who collapses at the finish and craps herself from the exursion?
 
2004-07-29 04:43:00 PM
server fatigue
 
2004-07-29 04:43:17 PM
I always picture Lisa from Weird Science,going:
"Now,drop and give me twenty!"

And everyone falls to the floor. ;)

Scroll down just a tad to find the story. Interesting stuff indeed.
 
2004-07-29 04:46:49 PM
office_despot I've been blessed with no refractory period until my third of fourth go-around. And sometimes I can bypass that too. Makes for interesting surrised looks on girls' faces. I used to think that it was all in a man's head, until I realised I'm just lucky like that. I'd rather be rich though.
 
2004-07-29 04:47:58 PM
WyattEarp, that sounds like fun- do you have a link of that footage?
 
2004-07-29 04:48:11 PM
Which head ?
 
2004-07-29 04:48:51 PM
v1agra, cia|is sales fall.
 
2004-07-29 04:49:40 PM
No but its been shown on TV, either wide world of sports or ESPN, not sure which - pretty sad to watch
 
2004-07-29 04:50:02 PM
NewScientist.com article is all in your head, Fark study shows.
 
2004-07-29 04:52:10 PM
Bah! I don't buy this for one moment. A short two weeks ago I was in Tai Chi and after only 30 minutes of warmup, my legs were so tired they were actually shaking-like leaves on a tree. Made it about 1/4 of the way thru the set and had to leave. Had sore quads for about 3.5 days. That was not simply in my head.

/end of exercise rant
//wants to RTFA, but link is farked :(
 
2004-07-29 04:53:24 PM
bullshiat. anyone who lifts weights knows it ain't all mental. I may be able to psych myself into the last failure rep but after that the muscle can't lift shiat

WyattEarp Was that Gabriella Anderson-Schiess in the 1984 Olympic womens' marathon?
 
2004-07-29 04:55:15 PM
This is the best news ever.
 
2004-07-29 04:55:40 PM
Bug2k,

I'm the same way I have no refractory period, I credit the fact that I was a loser in middle school and beat off like a dozen times a day. Of course, I'm fat, ugly, and hung like a two year old so women still won't sleep with me anyway and my gift to the world is wasted.
 
2004-07-29 04:55:59 PM
Oh, you can get muscle fatigue all right. Too many microtears in the fibers and a buildup of metabolites (only one of which is lactic acid). Turning off the feeling of muscle fatigue is all in one's head, not muscle fatigue itself. Besides, the feeling is usually a delayed onset.

/"massage therapists = whores"... then why can't I get paid like one?
//due to farked link, couldn't RTFA
 
2004-07-29 04:56:20 PM
No, I dont know who it was but I remember it being the Ironman

the research really only applies to people that are in shape.

out-of-shape people probably have many physical limitations that the brain underestimates during the exercise period.


the point really is, the brain is very conservative about physical limits when it comes to athletes.
 
2004-07-29 04:58:35 PM
Biologist where are you? I say this is a bunch of malarkey, but I'm not biologist (and the link is farked).

Hasn't anybody ever done a 30 mile road march with a 70-100 ruck sack? You can't move your body anymore...sure a shot of adrenalin here and there and those spiffy endorphins seem to keep you going for a while, but really now...Lactic acid is not in your head

WyattEarp Was that Gabriella Anderson-Schiess in the 1984 Olympic womens' marathon?

haha, scheiss. she pooped herself and her name is schiess. schiess sounds like poo.
 
2004-07-29 05:00:44 PM
Got to love the hidden point of the article, when you acctually do hit your pysiological limit...you die, so being a wuss is good for your health.
 
2004-07-29 05:01:01 PM
Wimps, you just need to "walk it off."
 
2004-07-29 05:01:58 PM
Oh, this is totally true. Honestly. I turn off the pain all the time.

Did I say "turn off the pain?" I meant "take a shiatload of PCP."
 
2004-07-29 05:02:04 PM
this may hold more water with aerobic rather than anaerobic/resistance exercise
 
2004-07-29 05:04:39 PM
I'd really like to read this; it might help me motivate my TKD students. :)

Tell me you knew this already. This was old news to me 10 years ago. One word that I will not tolerate in class: CAN'T.

 
2004-07-29 05:05:59 PM
Yeah they may be able to use this for training, but when marathon runners start getting eaten by packs of wolves at the end of their races, don't say I didn't warn ya.
 
2004-07-29 05:06:42 PM
link is not farked if you scroll up to Richard Pye
 
2004-07-29 05:14:17 PM

but really now...Lactic acid is not in your head


If you are getting cramps, then yes, lactic acid is knocking you out.

most athletes do not get cramps or muscle pain from lactic acid. Their training has made their system sufficently efficient that this doesn't pose a problem.



The hill from hell might have set Noakes thinking about fatigue, but it was a more recent discovery that made him start researching it in earnest. He calls this the "lactic acid paradox". Lactic acid is a by-product of exercise, and its build-up is often cited as a cause of fatigue. But when research subjects exercise in a decompression chamber designed to simulate high altitude, they become fatigued even though lactic acid levels remain low. Nor has the oxygen content of their blood fallen too low for them to keep going. Obviously, Noakes deduced, something else was making them tire well before they hit either physiological limit.

 
2004-07-29 05:17:09 PM
In other news cramps and PMS are also "all in your head"...

Yeah, pain receptors are in the brain, which is in your cranium. What about the acid that is burning your tissue away, is that imaginary?
 
2004-07-29 05:22:13 PM
"life would be too dangerous if our bodies allowed us to become so tired that we couldn't move quickly when faced with an unexpected need"

"But Noakes argues that the central governor theory helps make sense of interval training, a "sharpening" technique in which athletes do repetitive bouts of high-intensity exercise interspersed with recovery breaks"

"He believes that interval training works largely by teaching the central governor that going faster won't do you any harm."

Best quotes ever.
 
2004-07-29 05:23:31 PM
Ummm...so my muscles literally tearing themselves apart when I work out is all in my head? Mighty interesting, but I don't think I have that kind of will to keep up.
