Anabolic steroids could not only work during taking, but also long after the body performance strong

Norwegian scientists have discovered in trying on moms, as they write in the Journal of Physiology, that even after deducting the doping agent, the muscles of the mouse grew again when trained again.

The scientists had administered female mouses for 14 days of steroids (testosterone propionate), which in this time built 70 percent more muscle mass and 60 percent more cores in the muscle fibers. Three weeks after the end of the steroid delivery, they again had the same muscle mass as the mouse of the control group, which no steroids were administered, but the number of cores were preserved in the muscle fibers.

The testosterone mause had to take 3 months after steroid-taking, more than 10 percent of a mouse’s average life, for 6 days for strength training. Your muscles grew by 30 percent. In the control group, however, the muscle mass increased only slightly.

The scientists are based on the conclusion that there is a thought function in the muscles. However, the Norwegian scientists had also noticed three years ago with mouses, which only trains this study, but did not doped. Was suspected that the cores formed by the training remained here, also remained here, forming a persistent memory of the muscles that are not lost and storing earlier corpers.

As early as 2010, the scientists pointed out that athletes who once taken steroids could have a benefit of life, even if they no longer occupy them. From this they ended the conclusion if it is a similar "Thought-making mechanism" the muscles in people like mouse should give that athletes should be lived lifelongly when they have taken anabolic stain. The anti-doping agency WADA sees a lock of a maximum of two years after taking Anabolica.

The positive aspect of the muscle notice situation in the fact that the sporty fatigue that people have removed in early years could affect the higher age. At the age of old people, the education of new muscle cores is definitely back.
