It’s worse in BJJ!The people who didn't wash their uniform regularly smelled like cat p*ss, not fun when practicing self defense with close contact..

The wonderful Latin expression comes to mind here: Post Hoc Ergo Propter Hoc.I think things start get muddled when we try to sort out why things happen.
Sometimes I think that I don't really know if it works what I do, as there was not the identical clone me who started a different training regime let's say three years ago when I immersed into "repeat training". I could say very soberly: I snatched a lot, that I now can snatch a lot. That's it.All we have to do to really figure it out is take a few groups of identical people, and put them through slightly different training programs for a decade or so, and see what the results are
or rather the information entertains my doing.while science can inform the prescription
...looking at me as a whole: either I don't work what I know, or I don't know what works or I don't practice what works. Oh damn…we practice what we know works (
Ultimately, we know that most training works. I think the issue when comparing HIIT with HIT with HIRT (say that five times fast) is trying to figure out when each one is the most appropriate/efficient use of time. With respect to hypertrophy, I suppose it's a question of "My goals are hypertrophy and...[what?]" If my goal is big muscles that function aerobically, HIRT might be the ticket. If it's big muscles with a high lactate threshold, then maybe HIIT. If it's just big muscles and who cares about the rest, HIT seems to do alright.

Many years ago I asked my chemistry teacher about workout clothes smelling like ammonia. I didn't catch the details but he went through the components of sweat and what breaks down into what and concluded that it probably really is ammonia. I got the impression that it's from normal components of sweat and nothing nefarious. For what that's worth.
Me no understand it either.. but then again I'm more a dog person..now I feel a little bit like Schrödinger's Cat itself. It's not always easy to live in a world I can not "understand". This "whole" stuff is not only more mystical than I imagine, but than I can imagine.
Me understand this..I could say very soberly: I snatched a lot, that I now can snatch a lot.
Thanks Steve, I did look at it for a refresher before posting, just joking with Harald is all..
Wow, regardless of the back and forth on the thread, there is a ton of awesome information here! @banzaiengr thanks for posting those articles. I've read some of Craig's other work like the StrongFirst for Crossfit article: the StrongFirst for CrossFit amongst other things, but the HIRT one has programming that I want to try after Simple.
I am thinking about writing an article soon discussing a recent Journal of Physiology paper. In that paper, they investigated three groups:
-5 seconds of work and 30 seconds of rest
-20 seconds of work and 4.5 minutes of rest
-steady state aerobics.

It is lack of oxygen that causes most mitochondrial harm, not acid accumulation.
Even if this was an academically settled conclusion, these two states occur together in working muscle tissue. From a behavioral perspective, they’re exactly the same thing.
Great conversation. Over the next few months, you will see a few articles on these topics from myself and a person much smarter than myself. In Strong Endurance, we cover a great deal of the fine details of how much acid is the right amount. As Al mentioned there are quite a few individual differences that change what is happening. Thus, when we create a protocol, we are hoping it hits the desired effects, but it varies from person to person.

The results on the systems vary quite a bit. What is missing are the in-between work to rest intervals. We should have some more science on those coming out soon from the lab.

Blood levels and cellular levels drastically differ, and for good reason. Mitochondrial exposure is within the cell, not in the blood.
From a behavioral perspective, they’re exactly the same thing.
Again, yes and no. Blood Ph tends to be a little more alkaline compared to tissue Ph, but not by a huge margin.
In the mitochondria it can swing around quite a bit more to maintain efficient transport through the membrane(s). Interesting or maybe not given evolution, the ability of the mitochondria to produce ATP/unit of time is increased at lower Ph. At closer to resting Ph the rate slows way down. This maybe is one of the reasons for that fast initial PCr recharge at the stop of heavy exertion.
Either way mitochondria are pretty resilient to hypoxia and low Ph in the range of a healthy person - the system is self limiting in several ways. Getting a little off topic on this one, end of day we're just looking at responses to different strategies, whatever fits the goals. In whatever direction you push it, there is a trade off of adaptive responses, whatever the rationale.
Fantastic. How does this inform your training?
I don't think anyone has claimed that the body doesn't or can't adapt to repeated exposure to glycolysis. But the argument has been advanced that exposure to glycolysis has a higher cost to us than the alternatives, and that more glycolytic training can, e.g., be introduced in the ramp up to a competition for a competitive athlete and those athletes can still perform well, and according to at least some studies, better than those whose training doesn't try to minimize glycolysis.I don't avoid glycolysis as I have seen no reason to do so and many reasons why this is a positive for GPP. The body adapts to better use this when it is used often and within reason.
