Layne Nortan gives some pretty solid insights to hormone response from stress. I remember him basically saying you cant have a study look at one hormone and rule the body's response. Thus dictating that 2 hours of cardio generate more GH, therefor its anabolic is poor science. He doesn't address this study but he talks about coritsol similarly. check it out, probably more helpful then this article.

Its a coping mechanism. Long bouts of cardio put the body in a severe catabolic state. GH is an anti-catabolic hormone. Go figure.
No one wins if they are trying to boost GH thru this approach. You break even, at best. It is likely though that u lose a lot of muscle mass in the process.
Do long cardio routines if u want to lose weight or have a healthy heart. Other than that, dont fool urself.
And the Olympia guys are running 10+ iu of GH ED or EOD, which guarantees that when they do fasted cardio they dont lose muscle mass at all.
Combine GH or GHRP's with a bit of androgens and clenbuterol and yes, you'll burn massive amounts of fat without the muscle loss, even in extended cardio sessions.

This study does not appear to offer any new opportunities.
We have long known that starvation greatly increases HGH production but simultaneously increases cortisol. Both effects are driven by low insulin and glycogen depletion.
Dieting does this to a lesser extent and (absent anabolic steroids) it commonly results in a loss of one pound of lean mass for each pound of fat. It is reasonable to assume that extended aerobic activity has the same hormonal effect with the same tissue loss.
Increased HGH does not increase systemic IGF-1 under conditions of low insulin and hypoglycemia. Increasing systemic IGF-1 would require a huge bolus of amino-acids and glucose immediately after terminating the exercise before HGH declines.
The systemic isoform of IGF-1 is not particularly effective at increasing muscle and is responsible for most of the negative side effects of HGH injection. Conversely, resistance training increases the muscle-specific IGF-1 isoform within the trained muscle.
This study does not argue against the common wisdom that aerobic activity leads to muscle loss and interferes with muscle growth.

Dang good post, sir.
Especially the call out to the systemic IGF not being particularly anabolic. People dont realize that local IGF is what counts.

Local IGF, yes. Systemic, no.
