It's been probably fifteen years, since I've picked up a muscle mag, but back then, there were lots of articles about two topics that I never read about from legitimate sources like this webiste.

Maintaining a positive nitrogen balance

Minimizing the effects of cortisol (muscle destroyer)

Based on reading the labels at GNC the other day, positive nitrogen balance is still a big concern, but I've never read about it in a good book or this website.

I figure one of five things is going on here:

(1)The mags. are over emphasizing something that is rather insignificant.

(2)The advice given from legitimate sources like this one automatically take these factors

     into account with respect to  training regimens, nutrition, rest, etc.

(3)The two factors (cortisol and nitrogen balance) cannot be significantly manipulated 

     through training, nutrition, supplementation, rest intervals, etc.; so the legitimate

     sources do not even address them.

(4)I've just not read enough good sources.

(5)A combination of some or all of the three reasons listed above.

Well, all you need to do to maintain a proper "nitrogen balance" is eat a lot of veggies.  It is true that high-protein diets can through your nitrogen balance out of whack, but just eat lots of different veggies and you'll be good.

Regarding cortosol, that is a legitimate concern.  Part of the reason I (and others for that matter) don't write about it is because its gosh darn confusing.  I don't have a degree in exercise physiology or nutrition, and even if I did, the science out there is contradictory.  You'll find one study showing that a certain routine produces more cortisol but then when you read it you see that guys were doing strength training for 2 hrs on an empty stomach!

That said, you can be pretty sure that steady-state running starts producing cortisol after some period (45 to 60 minutes, if you believe the science papers).  Similarly, some – but only some – have shown that long lifting sessions also produce cortisol.  However, both these situations are mitigated by diet – having a protein-carb drink, for example, while working out has been shown to diminish the release of cortisol.

Manipulating cortisol is possible and is important for people reaching the elite limits of their goals (performance, strength, fat loss, etc.) just like manipulating natural growth hormones is possible and important at advanced levels.  But most good programs and diet and advice intrinsically takes this into account.  Programs work because they work and have been shown to work.  All the science details are there of course, but I worry about too many people getting obsessed with the tiny points of science and overlooking the basics of what has been shown decade after decade to work (just ignore the late 1980's, early 1990's advice because that was a bad time for fitness advice).

Great information Darrin!

The reason I constantly ponder on chemical and hormonal concerns is that I feel like there is something about the way my body reacts to resistance training, rest and proper nutrition that is different than most lifters.  My body seems to strongly resist gaining strength and size, regardless of my program (intensity, type of exercises, frequency, rest between sets, and volume) and nutrition plan.  I'm constantly searching for something I can do differently or, at least understand what's going on in my body, even if I can't do anything about it. 

With regards to a positive nitrogen balance, it is claimed by many companies that their supplements help produce this result, even though I don't quite understand the significance of staying nitrogen positive.  Sounds like this phrase is being used just to sell products.  If eating lots of vegetables is the way to create this balance, then I'm probably doing all I can do.

With regards to cortisol, I feel like it is possible that this is one factor that may hinder my progress.  Is it possible that some people start producing cortisol during exercise before others or more easily than others? 

From my reading, cortisol actually breaks down muscle and works counter to what most lifters are striving for.  But my workout durations never exceed one and a half hours and the intense part of my routine is usually 30 minutes or less.  I also sip on a protein/simple carb drink while lifting and take down another serving immediately afterword.  I then try to take in a solid meal 30 min to one hour later.  I've been on programs previously that are of much shorter duration (say 30 minutes) with no better results. 

On steady-state training, I usually go the minimum for aerobic benefit (20-22 minutes) and, I never exceed 30 minutes.  But when I start a lifting program, I can almost double my calorie intake (compared to a lifestyle with only a moderately physical job), and make only minor muscle and strength gains; and that's only for the first month or so; then I completely stall.

Another loose theory I have (and I need to do more reading on this) is insulin.  From previous reading, I understand that insulin helps produce hypertrophy and this is why we should eat simple carbs around our workout times.  While insulin is also attributed to depositing fat in our bodies, and therefore, simple sugars should be controlled throughout most of the day, creating this insulin response during and after workouts should help our bodies release other hormones that help grow muscle (testosterone, growth hormone, etc.).  I can't remember for sure, but it also seems like insulin also helps reduce cortisol.  

In my insulin theory, it is possible that my body doesn't easily produce insulin (type 1 diabetes) or produces insulin that doesn't properly react on blood sugar (type 2 diabetes).  In either of these scenario, sipping on a simple sugar would not help my cause, because the insulin (or the lack there of) would not produce the physical response I want.  The thing that blows this theroy, however, is that my blood sugar has run high only for the past few years, and this would not explain why I have a history of being a hard gainer, even in my early twenties.  However, throughout my early twenties, I knew very little about how to lift for stength and size, and looking back, I was doing almost everything wrong.

I just reread the book "Scrawny To Brawny".  Excellent book for people who consider themselves "hardgainers".
