Okay, I know you guys are wanting to see some of the science behind stuff related to bodybuilding. So here is just one of the reasons we recommend consuming a good gob of carbs immediately after training, and optionally adding a quick digesting protein to your post-workout meal. Maximizing postexercize muscle glycogen synthesis: carbohydrate supplementation and the application of amino acid or protein hydrolysate mixtures
Objective: This study investigated whether an increase in carbohydrate intake, ingestion of a mixture of protein hydrolysate and amino acids in combination with carbohydrate, or both results in higher postexercize muscle glycogen synthesis rates than does ingestion of 0.8 gMaximizing postexercize muscle glycogen synthesis: carbohydrate supplementation and the application of amino acid or protein hydrolysate mixtures
Objective: This study investigated whether an increase in carbohydrate intake, ingestion of a mixture of protein hydrolysate and amino acids in combination with carbohydrate, or both results in higher postexercize muscle glycogen synthesis rates than does ingestion of 0.8 g/kg/hour carbohydrate, provided at 30-min intervals. Design: Eight trained cyclists visited the laboratory 3 times, during which a control beverage and 2 other beverages were tested. After the subjects participated in a strict glycogen-depletion protocol, muscle biopsy samples were collected (ouch). The subjects received a beverage every 30 min to ensure ingestion of 0.8 g carbohydrate/kg/hour (Carb trial), 0.8 g carbohydrate/kg/hour plus 0.4 g wheat protein hydrolysate plus free leucine and phenylalanine/kg/hour (NOTE this combo was used because in other studies it has been shown to promote a larger release of insulin, also know as the carb+protein trial), or 1.2g of pure carbohydrate/kg/hour (Carb + Carb trial). After 5 hours, a second biopsy was taken. (double ouch) Results: Insulin responses in the Carb + Pro and Carb + Carb trials were higher than those in the Carb trial (88 % and 46 % higher). Muscle glycogen synthesis was higher in both trials than in the Carb trial (35 and 45 compared with 17 �mol glycosol units/g dry wt/hour, respectively) Conclusions: Addition of a mixture of protein hydrolysate and amino acids to a carbohydrate-containing solution (at an intake of 0.8 g carbohydrate/kg/hour) can stimulate glycogen synthesis. However, glycogen synthesis can be accelerated by increasing carbohydrate intake (by an additional 0.4 g/kg/hour) when supplements are provided at 30-min intervals.     | ||

This is my favorite as of yet. Definately a must read for those who wonder the importance of a post-workout meal. Very, very, very, good "Snippet". Although, most of the diet comes down to a person's daily caloric intake, this is a must get right meal for me. Keep the snippets coming MS. MR. BMJ | ||

OOOH I always did like thirds  Good one MS. Not to much hard core science, just enough to state the points! ------------------ Lobo |
