Creatine and Building Lean Muscle
Creatine is found in human body mainly in the skeletal muscles and in small quantities in the brain, heart and testes. The benefits of Creatine are observed through its role in intra-cellular water retention and by increasing ATP production. As Creatine is stored in the muscle cells, it enlarges the cell by using the water molecules that surround the cell. This increases the strength and makes the muscle look fuller.
When muscle strengthening exercises are carried out, this contracts the muscle. ATP is the compound which the muscle uses as fuel upon contraction. ATP releases a phosphate molecule as its contribution to build energy. Due to loss of the phosphate molecule, ATP becomes ADP. Within ten seconds of contraction, the energy contributed by ATP is exhausted. Now glycogen burning takes place for further muscle contraction. This process gives rise to the production of lactic acid as a byproduct. The burning sensation felt at the end of an exercise set is due to the build up of lactic acid. If no Creatine supplement is taken, one is forced to stop further muscle contraction.
However, the Creatine supplement intake comes into play now. It is able to provide the missing phosphate molecule to ADP, which, in turn, is reconverted to ATP and is ready for a further muscle contraction session. The role played by the Creatine supplement increases the muscle contraction duration during the exercise and permits the body to continue with the workout to further. Hence, one can exercise longer and harder. This in turn permits the individual to build leaner muscle.
