I think that the key take away from the article is that there are multiple factors in muscle growth and that optimizing one at the exclusion of the other is unlikely to yield any advantage. For example all the people that worry about carbs blunting GH production and limiting gains...
Kinda hard to raise your t levels when you've already got so much on boardI think it was a decent study, but doesn't really change anything. I think most of us will agree compound exercises, short rest periods and higher intensity will yeild better results. But the article had some great info. And I have heard some people say that doing compound exercises will generate higher t levels. MYTHBUSTED! Lol
Something is just not clicking here, I mean people us exogenous hormones like steroids to get big fast, yet raising our endogenous hormones doesn't get us bigger faster? What's the point of using steroids if the increase in hormones doesn't lead to better gains--which we know it does! And this study shows it doesn't! WTF IS HAPPENING, MY HEADS GONNA BLOW.. AHHHHH
Your muscles have GH and T receptors, quads are a big muscle hence the significant rise in GH and T from them, but the body is doing so in order to reach homoeostasis because the muscle is soaking it up, so whatever rise of hormones is happening is just getting used up by the legs. Either that or the study wasnt long enough.
Boundto you read it wrong brotha. There was a big increase in endogenous hormones for the group doing bicep curls + leg workouts. Increase in GH, IGF-1, and testosterone. Mythproved!
The point was that this increase in hormones should yield bigger bicep gains to the group also doing squats. However, there was the same gains made in the bicep by both groups. This showed that squatting (or ultimately raising hormone levels) was not necessary to make bicep gains like some people say "if you don't squat, you won't get big."
Here is the ultimate conclusion of the study:
"exercise-induced elevations in endogenous anabolic hormones enhances neither muscle hypertrophy nor strength with resistance training in young men."
The elevation of hormones like GH, IGF-1, and testesterone does not enhance muscle hypertrophy nor strength? Wtf? This just doesn't click. Am I missing something? Why do we use steroids then to induce muscle hypertrophy and increase strength when this study says the increase in hormones won't do s***.

As a general rule, a single antithesis to a common or even an uncommon rule doesn't rule out the legitimacy of the rule. There are multiple studies that conflict back & forth. Generally speaking, what makes a theory stand, are years of re-administration of the same theory until one outcome outweighs the other by a significant margin.
I'm not making an opinion on this particular test, just stating a general rule when referencing studies. Short of the common laws of physics, most theories have a tested antithesis, particularly in the human body, where personal genetics of participants aren't a measurable or controllable variable.... yet (not to mention eating, sleeping, experience, stress related cortisol levels, people who lie on their intakes...etc.)

This article was nearly hogwash, end of story.Your muscles have GH and T receptors, quads are a big muscle hence the significant rise in GH and T from them, but the body is doing so in order to reach homoeostasis because the muscle is soaking it up, so whatever rise of hormones is happening is just getting used up by the legs. Either that or the study wasnt long enough.
Your thinking is correct in challenging the legitimacy of this article.So the natural increase of endogenous hormones is so minuscule it doesn't cause any muscle hypertrophy or strength increase? That still doesn't make sense. If hormones in high numbers build muscle, then hormones in small numbers should build muscle at a smaller rate. The hormones job doesn't change depending on their numbers.
How did the group with higher hormone levels receive the the same gains in their bicep as the group with lower hormone levels?
Hectic are you saying.. The group that did both bicep curls and squats ended up having more endogenous hormones. However, overall hormone levels were raised and the hormones were distributed to the biceps AND legs. This means that the group who was working out only biceps, received the same amount of hormones in their bicep as the group working out bicep and squats which had an "overall" increase in hormones. So the legs hogged up all the hormones and gave the group doing bicep and squats the same amount of hormones in the bicep as the group doing only biceps?
4. Multi joint exercises might be working due to to other reasons. So don't throw out multi-joint exercises because the study says hormone increases does nothing.
Anoop
This is true.
Multi joint exercises work.
Shizz's quote is right. We who workout with multi joint exercises experience the benefits they provide.
We are here arguing about multi-joint exercises yet lets not forget that the article said NOTHING about multi-joint exercises being useless... it simply said the hormone spike they provide does not cause muscle hypertrophy or strength increase.
So before all of us give up on squats and deads.. let's remember this article had nothing to do with squats and deads. It only had to do with the hormone spikes that these exercises give us.
Great points have been made for & against the article.
It's just so damn hard to believe that exercise induced spike in hormones is useless for bodybuilding....
Thanks for linking the article and starting a discussion.
I will address some of the good questions:
1. Testoterone definitely increases muscle. But those are injections at supra physiological levels which changes the resting levels. Workout induced test spikes are minuscule and only last for 15-30 minutes and do not change the resting levels
2. The study had a 2 day gap between training days. This is enough for preventing any systemic effect overlap on the non exercised arm since the acute spikes do not last for more than 30 minutes.
3. This is the third study from the group, apart from others studies, which questions this hypothesis. And they all came out against it. So there is multiple lines of evidence to debunk this myth I think.
4. Multi joint exercises might be working due to to other reasons. So don't throw out multi-joint exercises because the study says hormone increases does nothing.
Anoop
Not so sure how that number 1 works by your logic. If that were the case then 18 year olds wouldn't or couldn't develop muscle mass quicker than 40 yr olds, more so, 42 yr olds should be able to produce muscle mass at the same rate as a 15-21 yr old.
I have more but it is time for work.

Just clarifying what anoopbal stated, as it pertains to your statements above, hardknock. What you're talking about are "resting" levels. Resting levels of test definitely have an affect on muscle mass.
With all due respect to the originator, the article was garbage and I agree with you that the whole concept of "testosterone does not enhance muscle hypertrophy" is total and utter trash.
What that is saying is that by spiking test levels (whether natural or synthetic) you cannot assist your body in developing a more hypertrophied muscle; this is utterly ridiculous and is toeing on bush-league tactics to get some hair-brained theory over with the public.
Also, I always figured the "theory" was that you cannot obtain an overall sizable body without squats and dead-lifts which is very much true. I have never seen a person who only did hamstring curls, bicep curls, leg extensions, and tri-cep presses that was stage ready.
Can one get into "shape" doing that with a little jogging? Sure!
Can one start looking as if they workout by doing that? Lower a little fat and look like they visit the gym? Sure!
However, you will not gain your max in size nor strength, that is written in stone.
autocrine growth factors
WOW.. Nature never seizes to amaze me. I didn't even know any mechanisms like that existed. That's awesome!
Can't say with 100% but that could very well be the mechanism of growth in the study for the bicep only group without a systemic rise in hormones.
Alright so Joe bloggs biceps get as big as Percy the power lifters biceps just by doing curls. But can he lift 500lbs off the deck?
To the last portion of your statement: I do not think that you read my following statement, no way that you could have. Because, due to my misreading of the poster anoopbal, I responded incorrectly. I then agreed with what he stated AFTER understanding his position.Hm, I have - on multiple occasions. Including myself very recently, with another unfortunate tear to my left calf precluding me from doing compound, multi-joint exercises. So, not written in stone whatsoever.
And I will give you a hero cookie if you can tell me why local autocrine growth factors in respectively worked muscles can be activated without systemic increases in endocrine hormones - i.e., why the study is valid on a physiological basis.

But the first part of your statement: You are saying that you have witnessed, many times, a bodybuilder perform at his/her top level, by not squatting or dead lifting? Also, you have seen power lifters gain maximum strength and size by not dead lifting nor squatting ...
Now I am talking "NOT" as in never before in their existence. I am not saying "not" as in say several months or 2-3 years.
figured the "theory" was that you cannot obtain an overall sizable body without squats and dead-lifts which is very much true. I have never seen a person who only did hamstring curls, bicep curls, leg extensions, and tri-cep presses that was stage ready.
As far as the argument goes, I responded to the article dismissing the fact that squats and dead lifts contribute to your overall mass, they do. I'm not sure why someone would try and prove that they don't.
