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.
They are specially equipped for explosive function for very short periods. The energy supply for those who run from about 60 seconds to three minutes is also stored energy, but in this case it is primarily glycogen stored in muscles (and blood glucose) that provides energy. Glycogen must be oxidized to pyruvate, lactate and CO2 to provide the ATP required for muscle activity.
