Sports Nutrition Supplements
A wide variety of sports nutrition supplements, including high-quality protein and its intermediate metabolites, various amino acids, creatine, pyruvate, glutamine, L-carnitine, and Chinese herbal medicines, etc., contribute to the training and physical fitness of athletes. Among them, supplements such as whey protein, branched-chain amino acids, L-glutamine, creatine, and L-carnitine can accelerate muscle synthesis, increase muscle strength, and have an effect on increasing muscle cross-sectional area and muscle strength. and post-exercise energy. The driving effect of the supply side is more significant.
1. Glutamine (Gln)
Glutamine (Gln) is not an essential amino acid and is synthesized by enzymes from glutamate and ammonia in skeletal muscle and liver. The body's requirement for Gln varies with the intensity and amount of exercise load, and Gln levels in the blood rise after short-term high-intensity strength training. Gln levels decreased significantly after prolonged endurance exercise. Gln supplementation can replace free amino acids to a certain extent and reduce the utilization of free amino acids in skeletal muscle tissue. It also increases protein production and controls protein degradation, thereby protecting skeletal muscle from excessive breakdown.
Gln, as a regulatory amino acid, plays an important role in regulating protein and glycogen synthesis, improving human immune function and intestinal capacity, and improving antioxidant function during exercise. In physical training, Gln supplementation is required to improve athletic performance.
2. Whey Protein
Whey protein is a high-quality protein present in whey, extracted and purified by ultrafiltration, and has high nutritional value. Because whey protein is not easy to coagulate under strong acid conditions, it is rich in branched-chain amino acids, which is beneficial to the growth, development and functional recovery of muscle tissue, and its biological efficiency exceeds that of free amino acids. The higher the biological efficiency, the easier it is to digest and absorb. Therefore, whey protein is made into beverages, protein bars and other commodities because of its high purity, high bioavailability, and scientific and reasonable amino acid composition.
