I normally never disagree with Kenny,
I usually don't disagree wth Tim but...:)
but IMHO, it depends on your situation. If you are trying to gain weight, then yes. But if not, then I might steer clear of preworkout hi GI carbs. Reasoning being, , as Kenny stated, it will raise insulin, which shuts down gh release (a fat burning mechanism). During and after seem to be reasonable, however, I only drink water during, but post workout, a hi GI will fit the bill nicely. Just keep it smaller in kcal if trying to shed the fat, but is still needed.
There are two schools of thought. One being to ingest a drink before, during and after you workouts as a means of enhancing recovery. Not doing so delays recovery.
The other school of thought being that not ingesting anything that raises insulin, will increase growth hormone.
First of all, I question exactly how much growth hormone is released. Is enough growth hormone released to compensate for the recovery delay you will expeerience from not ingesting a high glyceminc index carbohydrate along with whey protein.
Secondly, insulin has been show to be one of the most anabolic hormones there is. Ingesting a carbhydrate/whey protein prior, during and after the workout is two fold.
You replenish the muscle cells along with creating a stimulus (the release of insulin) for muscle growth.
From the data I have read, a greater release of growth hormone is released during sleep. This providing you have not ingested high glycemic index carbohydrates before going to bed.
The data also suggest that ingesting argenine and orthanine prior to sleep will elelate growth hormone even more.
Thus, the most effective method focus on your bed time strategy.
With that said, let me now contradict myself to some extent. I question how much growth hormone is released in sleeping, even with the argenine/orthanine supplementation.
I have no idea of who coined the terms "good" and "bad" for carbs,
People are stupid. No matter how you cut it. People always want a simple answer to a complex question. And it you can say it in two words, like "bad carb" or "good carb," even better.
but it is usually based on the gi (glycemic index). what is usally termed as "good are those that are slowly digested, inducing Insulin at a much lower rate. The term "bad" is usally used for carbs that are quite quickly digested, putting insulin at higher levels, very quickly. Note that insulin is a "storage hormone" that can be a double edged sword. Yes, it will store good stuff into the muscles, but at the same time, if you have too much intake, in terms of carbs, fats, protein, it will store the excess as fat after glycogen levels in the muscles are topped off
Well put. It much like asking which tool is the best tool in your tool boc. Thus, it depends on what you are doing.
If you want to drive a nail, a hammer is the best tool. If you are trying too put a screw in wood, a screw driver is the best tool.
However, I have used a hammer too put a screw in wood. It works but not very well...:)
