Fifty bucks for a t-shirt, eh? I've got to seriously reconsider my pricing strategy.

There should be a line of "I <3 IGx" hot pants for the closet IGxers to wear at @holefit events

It intuits well that if you can pass around a gigantic 10 lb medicine ball 50 times, you can deadlift 500-700 pounds in a year or two.

No wonder all those Super's are Morbidly Obese Underperformers, they are not wearing board shorts and wraparound sunglasses AND they are wearing shirts. WTF...

Pain Equals Potassium

By Brian MacKenzie

Oh the burn!

At some point during Karen, your quads start to tingle with a certain familiar sensation that can only be described as “burning.” As you work your way toward your 150th toss of the Dynamax ball, the feeling gets worse and worse until you heave the final ball to the wall.

We all feel lactic acid building up during a workout. Or do we?

It turns out the burning sensation actually comes from the accumulation of potassium outside the cellular wall. Lactic acid, more specifically lactate, plays a role in this process, but mounting evidence suggests it’s actually a fuel rather than the substance responsible for soreness.

The following video features Brian MacKenzie of CrossFit Endurance explaining the science of soreness and performance.

http://journal.crossfit.com/2010/08/end ... l#comments

He really tries to make it sound all professional and sciency-like, but....many aren't taking his word for it:

So why are no crossfiters competing and winning at the elite endurance level? they have the aerobic capacity AND the strength component?
you say that the missing link to elevated elite performance is not found in sport specificity, yet you have not produced any sport specific elite endurance athletes using the generalist approach.
maybe instead of saying that this is why the elite community is wrong, maybe you should say, this is the science to how a generalist can be a generalist and complete longer events.

I myself am a crossfitter but I dislike how this article/video was published with no scientific citations/publishings.

I would like to not only see citations for the claim that CFE is superior to long slow distance training, but I would also like to see the athletes that have reaped the benefits at high levels of competition. These presentations lack the data that Crossfitters are supposedly so adamant about to carry any real significance. I realize that its not necessary to discuss the minutiae of the physiology that goes on, but it has to be grounded in some kind of data or else it's just a guy talking.

If one is going to venture into explaining the exercise physiology/biochemistry black box then PLEASE make sure you provide complete, accurate and cited information. Temporary Na/K pump dysfunction and ion imbalances might be associated with muscle fatigue but it is FAR more complex than has been presented. Yes lactate is a fuel but "Lactate retards the acidosis process"?!?! Huh? Any undergrad ex phys student could correct him on that one! Intense training is having numerous effects on the body, far more than just on the Na/K pump!!!
I was once considering taking the Endurance Cert but seeing that vid makes me reconsider. Maybe stick to the CrossFit mantra of staying away from explaining the black box and sticking to measuring results only? Simpler and easier for everyone.

There is way too much conjecture in the video and the comments. "Trust me, I'm right" is not a convincing argument.
It's one thing to argue that a certain thing works but you don't know why (Black Box model). But it's entirely different, and useless, to argue why without proving it.

BRIAN: you said K+ shifting out of the cell (acidosis during strenuous exercise) was due to the increased activity of the Na+K+ pump! This is wrong information!

So, BMAC, too tired from DNF'ing over the weekend to respond with actual WORDS, posts a link to all the 'haters'

http://jap.physiology.org/cgi/content/a ... 107/6/1771

To which we get more replies.

Weak.
This research article supports the use of a taper in order to peak a performance which has been known and used by almost every running coach and athlete for decades. This study does not provide any evidence that it is a build up of potassium creating that "burn" sensation, it only uses 17 participants whom are split into two groups and by their times they are beginner runners who would adapt to almost any training stimulous.
I'm disappointed.

But, apparently all of these numerous people questioning poor BMAC is all juss hatin' from the intertubes, cause:

Excellent Information! We need to get this stuff - this type of info and training to our Olympic Marathon guys!

and

Maybe some of the commenting folks will make it to a cert and get a better understanding of what you are talking about?

OR maybe they like the distance of a computer to pop off at the mouth?

[Mountebank]

From the study:

For a 6- to 9-wk period, 17 runners were assigned to either a speed endurance group with a 25% reduction in the amount of training but including speed endurance training consisting of six to twelve 30-s sprint runs 3–4 times/wk (SET group n = 12) or a control group (n = 5), which continued the endurance training (~55 km/wk).

This is truly groundbreaking information. Interval training + LSD is good for endurance athletes. LSD without any speed training isn't as good. Wow. They should start re-writing all of the exercise physiology texts ASAP.

Where does spazzing around with weights and calisthenics, interval training, and NO LSD come in?

[Shafpocalypse Now]

So far, CFE 0, Every other traditional endurance training method 5, 678, 987 JUST THIS YEAR!

B Mack is wrong so often, he's got to be a professional buffoon!

[syaigh]

Most of these guys (these guys = "gurus" with little substance) read only the abstract and interpret from there.

The abstract is not exactly a summary, its simply a look at the author's thinking as to how they designed the study. The results and discussion are the important part, as are the methods. Reading just the abstract will get you nowhere, but people are lazy and/or uneducated about how to actually use the "scientific method". The results and discussion often present vastly different ideas.

Not to mention, basing a theory on a single experiment that is not the culmination of years of research that has been backed up and repeated by other groups is just silly.

You all set a pretty high bar when it comes to "scientifical".

Some people's idea of college involved only beer and business classes, Syaigh.

[friedquads]

Excellent find!

This would have also been acceptable.

I'm reasonably sure college involves many, many syringes.

Fucking ay @ Aleksanyan at ~4:30...he meditates on it and then he makes that bar float. Crazy strong guys.

I have much beer knowledges. Biology professors, doctors, and Jesuit priests love beer. I funded a lot of my beer education by helping hapless econ majors who drank too much beer and didn't read enough and therefore needed words like "strategery" taken out of their term papers.

[Shafpocalypse Now]

Yeah, it's the business classes that leave you flat. Beer almost never lets you down.
