Because colostrum is the prime source of IGF-I, its use by athletes has increased. The healing features of colostrum is attributed to IGF-I and IGF-II. They can build muscles and repair tissues.
Why do athletes consume colostrum?
Firstly, they use colostrum to build lean muscles, increase physical performance, and reduce recovery time between high-intensity training sessions. By inhibiting protein breakdown and accelerating protein synthesis, colostrum is the most effective natural muscle-building agent. Some researchers believe that colostrum is about 3 to 5 times more effective than synthetic growth hormones. During exercise and strenuous workouts, IGF-I triggers muscle cell proliferation and, consequently, increases muscle mass. IGF-I found in large amounts in colostrum, has an extraordinary ability to build lean muscle.
Secondly, as stated earlier, IGF-I can burn fats; therefore, colostrum is a natural fat burner. During strenuous workouts, the boby may break down its own protein instead of fats. Colostrum, as a source of IGF-I, can shift fuel utilization from protein to fat, thus, colostrum has an anti-catabolic effect. It improves the endurance ability of athletes by making fat available for energy supply and by stimulating the entry of glucose into the muscle cells. During times of rebuilding energy sources after a competition, colostrum provides most of the required nutrients.
Thirdly, studies have shown that a mild to moderate regular exercise help reduce the incidence of infection in normal healthy people. However, heavy workouts increase the frequency of infection. Vigorous exercise puts the immune system under stress. A number of factors probably contribute to the suppression of the immune system, which results in high rates of infections and sport injuries. By providing immune-enhancing factors, colostrum boosts the immune system; thereby, it prevents infections, which may occur after a heavy workout.
Finally, colostrum has a healing property that is important for athletes. Strenuous exercise causes damage in muscles, tendons, ligaments, and cartilages. Colostrum help muscles and other tissues repair and regenerates quickly. Eventually, these damages give rise to more serious sports injuries. Colostrum is very useful in healing athletic injuries, both minor and major.
