PWO Carbohydrates elevates Growth hormones?

[justinmonty]

Hey guys I've always thought Carbs post workout weren't great because they can cause a blunt in GH release especially if you train late at night however This study states the opposite:

To examine the effect of carbohydrate and/or protein supplements on the hormonal state of the body after weight-training exercise, nine experienced male weight lifters were given water (Control) or an isocaloric carbohydrate (CHO; 1.5 g/kg body wt), protein (PRO; 1.38 g/kg body wt), or carbohydrate-protein (CHO/PRO; 1.06 g carbohydrate/kg body wt and 0.41 g protein/kg) supplement immediately and 2 h after a standardized weight-training workout. Venous blood samples were drawn before and immediately after exercise and during 8 h of recovery. Exercise induced elevations in lactate, glucose, testosterone, and growth hormone. CHO and CHO/PRO stimulated higher insulin concentrations than PRO and Control. CHO/PRO led to an increase in growth hormone 6 h postexercise that was greater than PRO and Control. Supplements had no effect on insulin-like growth factor I but caused a significant decline in testosterone. The decline in testosterone, however, was not associated with a decline in luteinizing hormone, suggesting an increased clearance of testosterone after supplementation. The results suggest that nutritive supplements after weight-training exercise can produce a hormonal environment during recovery that may be favorable to muscle growth by stimulating insulin and growth hormone elevations.

what do you guys think?

A link or PMID would help.

Sorry I dont have enough posts to post a link yet

Then, what's the PMID or at least the authors?

Looks like a poorly written abstract to me. Heavy resistance exercise results in an acute release of GH relative to the intensity. However, it has been demonstrated that GH does not aid in myofibrilar hypertrophy.

I'd like to see the original article for methods, data, and statistics.

this is the title you can find it all over google:

[h=1]Dietary supplements affect the anabolic hormones after weight-training exercise.[/h]

hmm k thanks guys what are your views on PWO carbs?

another study is one found on abcbodybuilding called :A scientific investigation into the rationality Post workout Carbohydrate consumption

Mostly for glycogen resynthesis.

There are implications for varying modes of exercise and their synthetic rates of glycogen in exercised muscles (recovery for competition training, etc)

hmm so carbs PWO are only benifitial if performance is your main goal ( strength/ athlete , etc)? however if body comp ( mass/fat loss) is your goal you shouldn't consume carbs PWO?!?

There are many other benefits to consumption of carbohydrates (hormone signaling, cellular growth, hydration, etc)

With respect to athletic training, there is a 2h time frame post exercise in which synthetic rates of glycogen are at their peak. This would be the optimal time to consume carbohydrates.

Interesting. Ive also heard however that taking in fat after can increase insulin sensitivity. It was a study done by Dr. Mauro DiPasquale.
