My apologies in advance for hijacking…
Why would we care about GH when we can have direct increases in protein synthesis from consuming protein and carbs following the workout? In theory, we don’t need hormones to grow, but we need food.
This may be irrelevant because GH is mostly elevated form high rep training, which few people actually do on T-Nation (but that’s another point altogether).
HOA, this is not an attack.
Quoted from Dr. Squat (if you don’t know who he is, look him up!):
"Your preworkout meal, being comprised of low glycemic index foods, should be more than adequate to carry you through even the most grueling workout. If you haven’t eaten correctly prior to training, a sports drink may be the best thing for you. Also, remember that taking in sugar will cause your blood sugar (and, therefore, your insulin level) to skyrocket. If this happens after a workout, you may be able to replenish spent energy sources, but you’re certainly not going to get a significant growth hormone (GH) reponse from your training. The high level of insulin that invariably accompanies increased blood sugar will suppress GH secretion. No GH, no growth and repair! Remember, GH is the anabolic substance your body needs to following intense training in order to force an adaptive (anabolic) response. [/quote]
