However, too much of white blood cells doesn't always mean a good thing. A high white blood cell count(also called leukocytosis) isn't a specific disease but could indicate an underlying problem. This is why high white blood cell count always requires further medical evaluation. A normal white blood cell count is between 4,500 and 10,000 cells per microliter.
The first system is the Adenosine Triphosphate (ATP) is the immediate source for energy that is stored in muscle cells. As the phosphate is broken down (there are 3 of them for each molecule of ATP) energy is released. This system is only good for very quick and powerful movements.Then, ATP runs out and much be re-synthesized so the process can be repeated. Oxygen is not required for this to work, there are no waste products, but it is extremely short in duration. This system will last for about 0.5 minutes.his system is only good for very quick and powerful movements. Then, ATP runs out and much be re-synthesized so the process can be repeated.

Supply of energy for muscle contraction. Adenosine Triphosphate (ATP) is the immediate source of (chemical) energy for muscle contraction. Very little ATP is stored in muscle fibres (= 'muscle cells'), only enough to power muscle contractions for a few seconds. The ATP in muscles must be constantly replenished as it is used for various processes. The basic equation to describe the release of energy from ATP for use to power muscle contractions is:
