Some of us remain lean, without adhering to any restrictions in food and do not torment himself physically. Others can never lose weight, taking all these measures. Why? This question took up a group of doctors from the Medical College of London Hospital. Results obtained by researchers suggests that to blame an individual unit of muscles. It is known that our muscles contain two types of muscle fibers - the fast and slow. Fast fibers are shrinking faster, but as the fuel they use the glucose that comes with the blood. Slowly, as the name implies, are slower, but longer do not get tired because their gas - reserves of fat contained in the fiber. Relationship between the two types of fibers vary greatly in different individuals. Thus, in the quadriceps muscle slow fibers may take anywhere from 13 to 96 percent. After studying this relationship in microscopic samples of muscle, who took a special needle in 11 volunteers, the British issedovateli found that more than lean people, the more his slow fibers running on fat. On the contrary, are prone to obesity have more fast fibers, fats are not used. That's why these people exercise ineffective. In addition, their muscles get tired more quickly, making physical activity gives them more difficult. Change the nature of the relationship can not be mortgaged. But persevere, you can pretty much retrain their muscles, and fast fibers begin to behave almost as slow. For this purpose, as shown by tests, it requires at least six weeks of exercises.
