A complete blood count (CBC) gives important information about the kinds and numbers of cells in the blood, especially red blood cells, white blood cells, and platelets. A CBC helps your doctor check any symptoms, such as weakness, fatigue, or bruising, you may have. This test measures the amount of space (volume) red blood cells take up in the blood. 2  The value is given as a percentage of red blood cells in a volume of blood. 3  For example, a hematocrit of 38 means that 38% of the blood's volume is made of red blood cells.
At a typical cycling or running ârace paceâ, carbohydrate utilization is in the range of 2-3g/minute. Thus it is crucial to have a good glycogen stores as well as to have the proper carbohydrate intake during exercises lasting more than 2 hours.
During digestion, your body breaks down carbohydrates into sugar. The sugar enters your bloodstream, where it's then transferred to individual cells to provide energy. Sugar is stored in your liver and muscles as glycogen â your energy source. Increase your energy storage. Your muscles normally store only small amounts of glycogen â enough to support you during recreational exercise activities. If you exercise intensely for more than 90 minutes, your muscles may run out of glycogen. At that point, fatigue might set in, and your performance may suffer. But with carbohydrate loading, you may be able to store up more energy in your muscles to give you the stamina to make it through longer endurance events.
