There's a lot of performance potential to be found in this energy system. All CP or all aerobic is a pendulum swinging (over)reaction to all metcons all the time.Wow, Pavel agrees with me, this is amazing. Look at what he wrote last year:
'Anaerobic glycolysis is the sugar burning that supplies faddish “high intensity interval training” and “metcons.” This highly inefficient process pollutes your body with lactic acid, ammonia, and free radicals and messes with your hormones if you tap into it too much or too often.
A+A, in contrast, relies on the clean burning “rocket fuel” of creatine phosphate (CP) to power high intensity efforts and an equally clean aerobic system to replenish the CP.'
This would be some outdated thinking, what pollution or problem are we talking about here? Improved insulin sensitivity, increased hypertrophy, "lactate's role in mediating brain function. These canonical function involves learning and memory, cerebral blood flow, neurogenesis, and cerebral microangiogenesis, energy metabolism, neuronal activity, and neuroprotection. Therefore, lactate is competent to be a potential therapy for ameliorating the pathological process of some brain diseases associated with impaired brain function."Surely that "91% anaerobic" you are talking about here is the ATP-CP system (which I believe can be replenished by the aerobic system), not the disgusting polluting anaerobic glycotic system which we're talking about as the problem from the first post
"Too much or too often" are the important take-aways here.Wow, Pavel agrees with me, this is amazing. Look at what he wrote last year:
'Anaerobic glycolysis is the sugar burning that supplies faddish “high intensity interval training” and “metcons.” This highly inefficient process pollutes your body with lactic acid, ammonia, and free radicals and messes with your hormones if you tap into it too much or too often.

And interestingly inorganic phosphate seems to be associated with bone health"Too much or too often" are the important take-aways here.
And CP is far from consequence free. It is now understood to be the prime reason for decrease in contraction force due to fatigue - accumulation of inorganic phosphate, not ROS, lactate, or lowered pH. Is more important to focus on adaptive response to training strategy than theoretical metabolic shortcomings of sub-exhaustive energy utitization. Results speak for themselves, both in exercise science and biology.
"Some early studies conducted more than 10 years ago showed that acidification, if anything, resulted in an increased tetanic force at physiological temperatures"...
"Creatine has little effect on contractile function, whereas there are several mechanisms by which increased Pi may depress contractile function. Thus, on the basis of recent findings, increased Pi rather than acidosis appears to be the most important cause of fatigue during high-intensity exercise."
The only time you need this dumb anaerobic glycolysis system is for max efforts of 30 seconds. That is totally crazy. Almost no sport that people actually care about has plays like that except for maybe UFC.
Important to note they distinguish between anaerobic lactic (fast twitch) and aerobic (slow twitch). Pyruvate is undoubtedly higher than 10 or 15% contribution at a racing pace, still aerobic. IIRC on an older thread it was posted that competitive rowers had the highest % of type 1 fibers by total than any other sport specific athlete that had been tested.Rowing. Elite 2000m rowing times for men are <6 min.
Over the course of the race, it's about 10-15% glycolitic, lower is better, but it can't be eliminated under race conditions.

We have the luxury of contemplating concepts like this because we don’t have to use the anaerobic energy pathway on a regular basis. Increased fitness for survival to reproduce doesn’t necessarily equate to longevity and greater health span, but by golly, when you need it, you need it.
When trained and dosed accordingly, I’m sure it can support health span along, and I’d say most complete train programs must have some element of this on occasion. I’ve overdosed it for periods of time and burned out, so lesson learned.
A person can only do so much training. And this is especially true for athletes who care about results. Anaerobic training is most taxing, destroys the body, and significantly limits the amount of other training an athlete can do. So "use it or lose it" in this context actually has a very different meaning then what you intend: this terroristic training forces an athlete to lose out on their more important training.dmaxashman, I appreciate your sense of humor.
"...the disgusting polluting anaerobic glycotic system which we're talking about as the problem from the first post..."
As if one of the body's multiple miraculous ways of converting food into energy is disgusting
Like everything else, use it or lose it.
Really have you ever seen a football player do a 30 second explosive play? How many seconds does it take LeBron James to fake one way, dribble to the hoop and slam dunk, is that a 45 second move?Anaerobic training isn't crazy! It helps with explosive power and quick bursts of energy for sports.

You can see that this isn't true. We can use it continuously for hours, as the picture above shows. It supplements the energy needs that exceed the aerobic system. I do it every weekend on my 2+ hour bike ride. I'm riding a little harder than MAF, which would be blue. Glycolysis is kicking in the difference so I can work a little harder. But I stay below the lactate threshold, which would force me to slow down. Though that actually happens time and time again on a hill or hard effort. You can feel yourself exceed the threshold, things get hard, you are forced to slow down a bit.The only time you need this dumb anaerobic glycolysis system is for max efforts of 30 seconds.
