Carbohydrates are one of the three macro-nutrients of our diet. Unlike fats and proteins, carbohydrates are not essential, i.e. an intake of carbohydrates is in principle not essential. Since carbohydrates represent a main source of energy, they are essential for optimal mental and physical performance. Energy is released faster than from fat, the second major energy supplier.
Effects of carbohydrates
Carbohydrates are digested and transformed in glucose, which is a form they enter the blood stream. The so-called glucose blood levels reflect the concentration of glucose in the blood. Low concentration of glucose is accompanied by a feeling of hunger. Different types of sources of carbohydrates have various effects on sugar levels in blood, measured in glycemic index.
Highly glycemic foods give a sharp rise and fall in glucose levels, meaning they are readily available energy source. Low glycemid food on the other hand has a slower rise and slower fall of glucose levels. They are slowly available but long lasting source of energy. Glucose in blood reaches the organs and serves as an energy supplier. Our brain is needs a daily intake of about 100g of glucose. Carbohydrates are stored in a form of glycogen in liver and muscles, for when they are necessary. Muscles full of glycogen increase volume of muscles. Excessive carbohydrates are stored as fat, which means that excessive consumption of carbohydrates makes you fat and may increase risk of diabetes.
Carbohydrates, Insulin and Sport
Carbohydrates are particularly interesting for athletes, since they are dependent on high energy levels. With a higher exercise intensive athletes need higher supply of carbohydrates as a supply of energy in addition to lipids and proteins. On top of this, carbohydrates play a prominent role in muscle building. They stimulate secretion of insulin. Insulin injects proteins, carbohydrates, creatine and other nutrients into body cells, creating a positive hormonal level. This means that insulin is an anabolic hormone controlled directly by carbohydrates.
The level of insulin depends on the speed at which the carbohydrates enter the blood stream as glucose. This means that glycemic index provides information about insulin action. The higher the glycemic index, the stronger is the insulin action. Secretion of insulin can also be stimulated through fast proteins and other substrates such as pinitol. Highly glycemic carbohydrates create an anabolic environment, and help to replenish stores of glycogen after training sessions, improving regeneration and muscle volume. Our supplements contain highlt glycemic carbohydrates that supply with quick energy and massive anabolic boost to insulin. Long term supply of glucose may go well with low-glycemic food.
