Glycogen is a polymer/polysaccharide that serves as a form of energy storage in animals and fungi and is a primary carbohydrate storage form in animals. Glycogen in humans is made and stored primarily in the cells of the liver and the muscles which functions as the secondary long-term energy. Glycogen is often referred to as animal starch because it is the complement of starch in plants for they have a similar structure to amylopectin but more extensively branched and compact than starch.

Premium Glycogen Glucose Metabolism
Glycogen and insulin are the hormones in the body that helps regulate the blood levels sugar and glucose in the body. Glucagon works in such a way that it counterbalances the actions of insulin. It takes approximately four to six hours after eating‚ for the glucose level in the blood to decrease‚ which causes the pancreas to produce glucagon. The hormone signals the muscle cells and liver to change the stored glycogen back into glucose. Glycogen and insulin always work together to balance the blood

carbohydrates aid and hinder your athletic achievements is that carbohydrates act as the fuel for the body also known as glycogen (Peterson). Glycogen is a starch that is easily broken down and is primarily used in the liver and muscles; however both areas use glycogen differently. Liver glycogen is used to keep ones blood-sugar levels high whereas muscles use glycogen to fuel themselves (Peterson). Now there are two types of carbohydrate loading the traditional method and the overload

Chocolate milk – the new post-exercise recovery drink of champions! The process of glycogen synthesis is called glycogenesis (Figure 1 Panel A) and glycogen degradation is called glycogenolysis (Figure 1 Panel B). Glycogenesis is the process by which the body stores excess glucose that is not required for ATP production through the production of branched glycogen. When we consume chocolate milk‚ we are in part consuming glucose‚ and glycogenesis may consequentially occur. Initially‚ glucose

Carb cyclingHigh carb day means more carbohydrates and less fat and low carb day means less carbohydrates and more fat. Carb cycling increases the benefits of carbohydrates in your dietary plan‚ especially if you are about to have a competition. Increasing muscle glycogen and glycogen replenishment are the

intensity periods of the race. This will interfere with the contractile proteins of the muscle and causes fatigue. 60% of Lactic Acid can be removed by the body using it as a metabolic fuel. It can also be removed by the conversion of either protein or glycogen. The time that this would last for is between 10 seconds and 2 minutes. Aerobic System (oxidative system) is the last of the three energy systems to be used. It is used after the Lactic Acid has been used and will be used for the vast majority of
