Evidence that squats release more HG hormone?

[No_Joke]

I read this in every bodybuilding routine advertised on the internet.

Does anybody have a link to the original study?

If not, at least the name of it, and which university or company did the study?

I can access my college info databases if the info is copyrighted/protected from being linked w/o permission.

I dont doubt its true, but I'm curious as to the extent of the effect. Can a doctor measure your levels of HG hormones by taking a blood sample?

your instantaneous hormone levels fluctuate wildly throughout the day.
it was never proven that the exercise raised average long term levels, only transient fluctuations which arent worth much.

^^ Exactly. It would need to elevated for many hours to make any difference to muscle growth.

Squat because it's badass - that should be enough.

I have no idea where the "original" study was done. Just a guess--the Soviet Union.

The 'netz is full of studies disproving the myth of some 'hyooge hormone release' from Squats, or any exercise, for that matter. Whenever this topic comes up here (about 10 times a day, it sometimes seems like) I usually just cite this one and then call it a day:

Conclusion

Don’t waste your time chasing GH spikes during and after your workouts. The evidence overwhelmingly indicates that workout-induced hormone spikes have no effect on muscle growth and strength gains. Focus instead on optimizing far more important training variables such as volume, frequency and exercise selection.

Can a doctor measure your levels of HG hormones by taking a blood sample?

Sure. Just realize that any such test will only provide a 'snapshot.' IOW, it will only reveal hormone levels at that particular point in time, and that they likely will show a different outcome if tested a little later in the day. As already stated above, hormone levels are changing constantly all the time. Just about any activity in which you engage, even sleeping or eating a meal, will cause them to change.

Forget about this notion entirely.

Squat heavy. Squat often. EAT MORE FOOD. Profit.

Here's a study that suggests that any raise in hormone release from compounds like squats is negligible.

'Testosterone and Exercise Research Studies - Men
Some research studies have shown that it is possible to increase your testosterone level by exercising. For example, in one study Schwab et al. (1993) measured the testosterone level in 2 groups of male study participants to obtain their baseline level. Then they had both groups perform four sets of six squats. One group of men did their squats using heavy weights and the other group of men performed their squats using light weights. After both groups of men were finished doing their squats, Schwab et al. remeasured their testosterone levels. They found that testosterone levels were increased from the baseline in both sets of men, regardless of whether or not the had used heavy or light weights. However, 10 minutes after the men were through exercising their testosterone levels dropped back to the baseline level.
In other study, Vogel et al. (1985) found that men who rode a stationary bike for 15 minutes had an increase in their testosterone levels from baseline. No information was available for how long testosterone levels were raised.
A different study by Craig et al. (1989) found that strength training for 45-60 minutes raised testosterone levels in both young and elderly men, but not to a level that reached statistical significance.
In a more recent study, Marin et al. (2006) found that exercise also increased testosterone levels in men. Men who participated in this study had their testosterone level tested prior to exercising and then again after performing lat pulls, bench presses, leg curls, leg extensions, leg presses, and military presses. Immediately after exercising the mens' testosterone levels were significantly raised, but then dropped back to baseline levels after 20 minutes had passed.
From the studies described above it appears that exercising may increase testosterone levels, but that increased testosterone levels drop back to baseline levels shortly after the exercise is over. However, there are also a few studies that show that exercising decreases testosterone levels in men after exercise (e.g., Wheeler, 2003) and so the jury is still out as to whether or not exercise can increase testosterone levels.'
