GH Production and Working Out


#1

Hi,

Do any of you know what the best way of maximizing GH output during your workout is. In other words what set rep combination is best for this. (Heavy weights+one down set, or high volume etc.)

I know GH is overrated when it comes to building muscle but I'd still like to know.

thanks

Moderate volume, higher load (4-6 sets of 5-8) with shortish rest periods tends to work best as far as I know. I could be wrong though, it's been a while since I read much on it.

It also maximizes GH output if you don't drink anything during the workout (keep it brief, around 40 minutes) and are in a gym that is slightly warm (80-85 degrees) or slightly chilly.

GH is most important for nighttime restoration, though. The transient raises aren't really significant, like you said.

Ask Dr. Hatfield it's one of his big areas of interest.

Search lactic acid training for fat loss. I beleive it mentioned about GH production in it.

And that's what I was thinking. I believe GH production is linked to lactic acid generation - so the more intense the workout, the greater the GH response.

If so, I have a question. Firstly, I have to wonder what a cycling sprint session would do for you (I say this because I did one the other day for the first time - I usually do sprinting either by running or rowing). I'd appreciate thoughts on the following:

On an exercise bike, sprinting involves primarily lower body muscle mass only. I know everything else is used, but they are the ones doing most of the work - much more so than rowing, elliptical or running, for example. This means, your cardiovascular system is used to support essentially the leg muscles only, which means they can work much harder than, say, track-running (where your arms, chest etc. take some of the cardio effort).

My question is: would GH production during a bike sprinting session exceed that of a track or rowing sprint, assuming all other things were equal?

My first bike sprint left me sitting - I could not stand up for a minute or two, and when I did, my legs were so weak that I risked falling over with small steps. It was quite weird (naturally, I'm going to have at-it again :-)). After rowing or running sprints, I huff and puff, but I never have that kind of fatigue. The interesting thing about the bike for me was that I was huffing and puffing LESS than I do for rowing/running. i.e. as if my cardiovascular system was more capable than my poor legs were in (relative) isolation.

Any expert comments on this?
