If you want to have a strong physique, exercise is what you must do, without a lot of iron lifting and sweating, how can you have pectoral muscles, abs, biceps, but now a group of scientists from Japan have found a shortcut that can increase muscle, so what is this shortcut, let's take a look at it together.
In a word, to understand this shortcut, it is actually the "super serum" extracted from the black bear's body. It is estimated that many friends who love fitness should know that as long as they continue to exercise for two or three weeks after they have worked hard to train muscles, then the muscles they have trained before will slowly lose. But the black bear is different, and its muscle mass will not decrease significantly for several months even if it does not eat or drink during hibernation. And it is precisely because of this situation that scientists began to carry out relevant research on the body of the black bear, and finally found that the reason why the black bear can not move and maintain its own muscles has a lot to do with a certain mysterious component of the blood in its body.
Modern medicine has shown that the amount of muscle in the human body depends on the balance between muscle protein synthesis and decomposition, when people's bodies lack exercise, the body will automatically secrete a decomposition enzyme called MuRF-1, and the production of this substance causes the loss of muscle mass in the adult body.
From the speculation of Japanese scientists, it can be known that one of the ingredients present in the blood of black bears in the hibernating state is exactly the opposite of the decomposition enzyme of MuRF-1, which can promote the synthesis of muscle proteins and increase the muscle content in the body.
In order to prove their conjecture, they also made a special experimental verification, the serum of a black bear was extracted from the summer, one was extracted from the winter, and then added to the human skeletal muscle cells for culture, and finally found that the black bear serum extracted in the winter can promote the growth of human skeletal muscle cell protein, while the summer can not.
