Bodybuilding: Muscle Creatine absorbs more glucose

The fact that creatine complete glucose muscle cells is not new, the relationship between the balance of glucose and creatine supplements is so strong that doctors are considering using creatine as a drug against Type 2 diabetes because in people with osteoporosis, the body becomes insensitive to insulin, and there the hormone in sufficient quantities, as a result, cells do not absorb sufficient glucose.

The researchers wanted to know if creatine really had to muscle cells more sensitive to insulin, which is why the University of São Paulo, Brazil conducted an experiment with 6 healthy young men, half of the men took creatine for 20 weeks during the first week took 24 grams of creatine per day, and during the other 11 weeks, managed only half that amount.

* All volunteers involved in the training experience performed 3 times per week where they had to run for 40 minutes at 70% of their VO2max.
* Immediately before starting the cycle of creatine and again after 4, 8 and 12 weeks, researchers gave volunteers glucose and measured the speed with which it disappeared from the blood of men, the faster this happens, more glucose will have been absorbed by the muscles.

According to tests, the combination of training with creatine supplementation actually increases the absorption of glucose pending whether creatine influence on insulin levels.

* To determine if this is the case, the researchers measured the concentration of insulin in the blood of the volunteers in the morning.
* The researchers expected that supplementation with insulin increased insulin production, but that did not happen.

found no statistically significant effects, so the muscle cells of creatine users should absorb more glucose through a mechanism unrelated to insulin.

The researchers suggest that the muscles are likely to produce a larger amount of the glucose transport protein GLUT4 and other possible factors include a greater production of IGF-1 by muscle cells or muscle cells to swell and as a result absorb more nutrients through osmosis (movement fluid compartments separated by a semipermeable membrane).

The results of the investigation of the Brazilians are, again, proves the value of creatine supplementation for athletes and coaches, and physicians, the results indicate that we do not know enough about how creatine works and can be an alternative to several complications.
