"Avoid Carbs and Stimulate Amino Acids Uptake
Ken Hess
February 19th. 2010 - You’ve probably heard that eating a high carbohydrate meal after training is better than a low carb meal. However, this may not be the case. Keeping post-exercise carbohydrate consumption low can prolong the nutrient uptake window created from training (via increased insulin sensitivity). (1) This is because training increases the muscle cells demand for nutrients, including amino acids, for repair and sugars to replace muscle glycogen.
The resulting increase in insulin sensitivity after exercise enhances the flow of nutrients to the muscle cells in need, as well as increases the use of fat as an energy source since sugars are not available. As glycogen stores fill up, however, the cells ability to take up amino acids (for growth) and fat (for fuel) will decrease.
The idea behind the high carb theory is that when you exercise, you use up muscle glycogen. The most efficient way to replenish your glycogen stores is through carbohydrate intake. If your training frequency has you exercising several times a day or every few hours, you’ll need too replace your energy stores more quickly to prepare your body for the next workout, and eating more carbs post exercise will help. If, on the other hand, you train once per day or several times a week and are more concerned with body composition, a carbohydrate restricted eating approach may prove more effective.
