No, I base it on education, not saying youre lacking in that department however. Why not pick a sugar which has an effect on muscle glycogen, since you are lifting? Fructose primarily fills liver glycogen, which is useless to us as weight training athletes.
normally post workout i have a shake with 150 carbs (complex) and 100g protein. then again two hours later eat a meal with close to same ratios.
beleive me i have tried everything and have found what works best for me. a piece of fruit is about 100 calories and 25g carbs.
it is my understanding that glucose for anarobic activety has to be broken down into frucose befoer it can used for energy anyway. so why not eat the frucose?
here's an excerpt from a long article but it states basically my point. I had to look a while to find it as i wanted make sure what i thougfht i knew was correct. i have been known to make a mistake maybe once a year or so.
Extracting Energy from Glucose
Two different pathways are involved in the metabolism of glucose: one anaerobic and one aerobic. The anaerobic process occurs in the cytoplasm and is only moderately efficient. The aerobic cycle takes place in the mitochondria and is results in the greatest release of energy. As the name implies, though, it requires oxygen.
Anaerobic Metabolism
Glucose in the bloodstream diffuses into the cytoplasm and is locked there by phosphorylation. A glucose molecule is then rearranged slightly to fructose and phosphorylated again to fructose diphosphate. These steps actually require energy, in the form of two ATPs per glucose. The fructose is then cleaved to yield two glyceraldehyde phosphates (GPs). In the next steps, energy is finally released, in the form of two ATPs and two NADHs, as the GPs are oxidized to phosphoglycerates. One of the key enzymes in this process is glyceraldehyde phosphate dehydrogenase (GPDH), which transfers a hydrogen atom from the GP to NAD to yield the energetic NADH. Due to its key position in the glycolytic pathway, biochemical assays of GPDH are often used to estimate the glycolytic capacity of a muscle cell. Finally, two more ATPs are produced as the phosphoglycerates are oxidized to pyruvate.
if you got some data post it and i would love to read it. or just send me some links that are not over a couple years old. you know how quickly things change now a days.
nice reply though. look forward to your response.
