Your definition of overtraining is not correct. Youre implying it can occur from a single session when it cannot.
If someone doesnt progress, overtraining should not be your knee jerk reaction. Your immediate focus should be to see if injury is an issue then move back to see how their training plan is designed. It may well be lack of recovery but for a BBer this is hardly ever the case given the amount of rest between movement sessions (unless youre even more of a bro) and the intensity of the average BB session is usually not high enough to lead to overtraining.
Also Its not a "theory", there are studies on volume, intensity manipulation readily available, if it were only a theory then coaches, strength and conditioning experts, physiologists etc wouldnt have a place in this industry.
I am wondering if your views are grounded In research as I would love to read them if possible
Someone who has never training a movement before will not stimulate all the motor neurons in that movement - this is why noob gains exist because you effectively train more motor neurons to activate [Read more here:
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4001023/ and here:
http://www.ncbi.nlm.nih.gov/pubmed/16464122] also, when volume is equated tained individuals recover faster than non trained [
http://www.ufjf.br/reabilitacaocardiaca/files/2008/07/EPOC.pdf] which is hardly surprising given the metabolic and neural adaptations that occur in a trained status. Mind you, giving an untrained person the same routine (volume, intensity, density etc) as a trained person would likely result in them fatiguing in the session much faster as they have not yet acclimated to that workload.
Also your srint analogy is off. Recovery IS a component of performance - you distinguishing the two separately doesn't make them separate. The ability to recover between training bouts (in this case sprints) IMPROVES performance. The lack of recovery between bouts shows lack of performance in that component. Additionally, 2-3 workouts is not enough time to see enough change to warrant an 100% increase in volume and in this case again, the lack of recovery shows their lack of performance capability.
Also a weight increase is relative and makes no sense in this context. If you can hit a 220lb bench press for 1 (at 100% 1RM) then 12 months later hit a 440lbs for 1 (100% of 1RM) then the net effect of the intensity is the same and the recovery would be similar. The fact it is more weight fails to take the % of intensity factor into consideration. I can recover faster from 12 sprints than I could a year ago at 1 sprint.

Your definition of overtraining is just plain wrong. For example, your second person is by no means experiencing overtraining because they've plateaued. The reason for it is simple and you even put it: no programming. Overtraining will not have just a single effect of stagnation. There's often regression, injury, and illness.
It seems you're also mixed up on what exactly recovery and performance are. The better your body is conditioned, the more stress the body can handle. The higher the threshold, then the better the recovery capabilities. If it only takes you 90s to recover from a set as opposed to 180s, then your body (and brain) have become more efficient and can handle the stress better. Due to this, your recovery will also be improved. That's more or less the principle behind periodization: ramping up your training as your body becomes more adept at adapting to the increased stress aka recovery. The better your base layer of conditioning, the shorter time you need to spend during the initial phase(s).
You're viewing the CNS as a muscle when it is VERY different. Overtraining is a metabolic condition and not just something that applies to the gym. It's not even completely an overtrained state, but anyone that's done a PL meet will tell you how awful they feel the next day. This isn't due to muscular fatigue; it's completely due to CNS fatigue. Also, having a certain base of conditioning is necessary to complete said even as they often last 8+ hours.
Man, where do I begin. First off, my definition of overtraining is something along the lines of "Having stimulated muscle growth, you are not seeing results on a workout to workout basis." This is built on the assumption that one has actually stimulated muscle growth and the following assumption that the simplified process of muscle growth is, "Stimulate > Recover > Grow" Having said that, if you are indeed stimulating muscle growth, and not growing, then what are the possible causes? Under training can't be the issue - you've trained sufficiently to stimulate muscle growth. What other issues are left? Insufficient recovery and/or insufficient time for growth. If my definition is off, cool. It is a very simple definition. How would you define it? (I mean this sincerely)
Second, I'm not suggesting it can occur in a single session AT ALL. I am suggesting that it takes 2 sessions to overtrain. I am sure you would agree. For instance, if I go in the gym and completely kill my chest workout this morning and then go back tonight and try to kill it again, will I make progress tonight? No, I will NOT see improvement. Why? Because I have NOT allowed for time to recover from my workout this morning, and since I have not recovered, my body has not had time to make changes either. This can happen if you train twice in one day, but it also happens a lot when you train twice a week too, and sometimes even training once per week.
Also, I will take the recovery/performance example a step further then. If you do a sprint, at 100% take a break, and then do a second sprint - again, all out 100% - will it be as good as your first sprint? Or will you be just a little bit slower? Could this be because you haven't fully recovered yet? You may have higher performance levels in sprints 1 and 2 than you would have if you were untrained, but you are still going to lose ground, you won't be recovered. And if your muscles haven't recovered, your CNS certainly hasn't even started the process. That is why I am saying there are two ways of viewing recovery - performance (how long can I go and how fast can I go again) and recovery (my body has repaired all damage and either begun to adapt if the body sees it as necessary).
Second, I'm not viewing the CNS as a muscle. I don't think it can be trained, it doesn't adapt the same way that muscles do. The argument AGAINST my view is saying it can be trained and adapted (like a muscle).
As for my views being based in research - I read studies, but only as they come available to me. I don't search them out. I'm just not good at that. My views are more based on my thinking about this, reading whatever I come across, thinking more, experimenting on myself, and seeing where others have failed in this. I don't discount studies at all - but I admit it's not my strong suit. I need to get better there, I'm sure there's an interesting world I've yet to fully uncover.
Also, someone mentioned overtraining being a buzzword that is thrown about too much and I agree - I think it's a fundamental part of training though. We all have limits.
And I am not saying that overtraining should be a knee-jerk reaction if you are not progressing. It should be a logical reaction. The knee-jerk reaction should be, "Am I sufficiently stimulating muscle growth" because THAT is the premise that this is built upon. If you ARE stimulating muscle growth, and you're not growing, there aren't many options at hand.
Finally, Jiggz, you are pointing out that a weight increase is relative, and that is kind of my point. 100% intensity is strenuous and difficult to recover from - period. BUT, you HAVE to be burning more calories, experiencing more protein turnover, etc. if you are bench pressing 440 pounds than if you are benching 220 pounds. Your body can only synthesize so much protein and recover from all this training so quickly. If you've been training for 1 year or 5 years, I would bet the rate at which your body can synthesis protein has not changed THAT dramatically, it isn't like you are synthesizing protein twice as fast just because you have twice as much muscle.
Rodja and Jiggz, I REALLY believe all 3 of us have more similar views than you may think. I wonder and hope you see some similarities. You're both asking some great questions, and I know you guys know your stuff, so I'm not trying to claim I am smarter than or know more than either of you - actually, I hope I'm not coming across as simple minded. But these discussions are great.
