In the sixth installment of the continuing Violent Agreement, coach Greg Glassman lobs a cherry bomb into the long-standing argument about the importance of localized vs. systemic lactose tolerance. As he steps back, Dr. Nicholas Romanov and Louie Simmons step in and try to sort out the mess.

Prepare for a ride on the Krebs cycle, with stops featuring Dr. Romanov’s linking of vomiting and fear, Simmons’ roll call of the major injuries he’s beaten, and Coach Glassman’s passion for gymnastics.

Great stuff. Meeting of the minds. I hope there is more. This would be great as an hour long documentary or mini series on CrossFit TV. I'd pay for that. I'd trade the 100 channels of doody I have now for a channel of CrossFit shows like this!

With regard to "fear" during exercise or exertion... This paper came out last year that has some pretty neat implications on that topic; perhaps connecting blood pH or anion gap with CNS fatigue or central governor theories?

Below is the abstract and citation, reprints do cost $$.

The amygdala is a chemosensor that detects carbon dioxide and acidosis to elicit
fear behavior.

The amygdala processes and directs inputs and outputs that are key to fear
behavior. However, whether it directly senses fear-evoking stimuli is unknown.
Because the amygdala expresses acid-sensing ion channel-1a (ASIC1a), and ASIC1a
is required for normal fear responses, we hypothesized that the amygdala might
detect a reduced pH. We found that inhaled CO(2) reduced brain pH and evoked fear
behavior in mice. Eliminating or inhibiting ASIC1a markedly impaired this
activity, and localized ASIC1a expression in the amygdala rescued the
CO(2)-induced fear deficit of ASIC1a null animals. Buffering pH attenuated fear
behavior, whereas directly reducing pH with amygdala microinjections reproduced
the effect of CO(2). These data identify the amygdala as an important chemosensor
that detects hypercarbia and acidosis and initiates behavioral responses. They
also give a molecular explanation for how rising CO(2) concentrations elicit
intense fear and provide a foundation for dissecting the bases of anxiety and
panic disorders.

AWESOME conversation, I LOVE hearing the stories of training for time and those who throw up being psychological factors - AMEN!

Those who throw up, majority of the time, are scared.

Once the athlete gets confidence and loses fear of the workout, he is a better athlete AND a better lifter.

I said "most" b/c I have seen some dudes who always throw up and they just have that weak stomach

Looking forward to more, hope there are more!!

This book discusses various stress responses:

It's well written - describing complex topics.

I answered the question about the "throwing up" mechanism this last weekend in Golden Co at my level 1 cert. It's is most likely attributed to the activation of the SNS (sympathetic nervous system)aka the fight or flight response. When you do Fran for example, you are able to put your body under enough stress and PAIN that your nervous system/body actually interrupts it as a life or death situation. This is why you see people throwing up, passing out, urinating (yes it happens in track all the time), or even going into shock.
Hence the sayings "scared the piss/shit out of me", or "he was so scared he pissed himself". If anyone wants more information on this just let me know.

Ten years ago i was coaching outrigger canoes we had one of the faster teams in the world at the time. One of our guys would throw up before every race. Pure fear of faliure
