Description: Endurance exercise fat is "hard" Nutrition is to provide a long low-intensity exercise and most of the energy the body needs. In large amount of exercise, the general intake of fat into fat globules in the blood, is the heart, muscle and fat tissue to absorb, because their blood in the first peak of insulin, glycogen is consumed first, the fat in no time (or do not need to) use, they are stored in adipose tissue. And often engaged in fitness training is different, they are often temporarily suppressed insulin levels, blood fat, muscle uptake can be as soon as possible, storage, and took the lead in the body metabolism, without first stored in adipose tissue. Fat for bodybuilders, the first high-quality energy, rather than the body burden.
