With the increasingly fierce sports competition, in order to achieve excellent results, athletes need to constantly challenge the limit of physical fitness and bear super-load exercise in daily training. The body is in a state of water loss, protein decomposition, and electrolyte loss for a long time. Therefore, a reasonable diet Nutrition is the basic material guarantee for maintaining athletes’ health and normal training.

Muscle strength is the fundamental guarantee for human sports. Protein is the main substance of the body’s muscle composition and the raw material for athletes’ muscle repair. However, the efficiency of protein absorption from diet is low, and excessive lipids will be brought in. Therefore, the research on protein nutrition provides favorable material guarantee for athletes to achieve good results.

Types of protein nutrition food

Protein nutritional food is mainly divided into protein powder, amino acid, and polypeptide nutritional food. The main function is to provide high-quality protein for the human body to keep protein metabolism in a relatively balanced state and promote muscle repair and synthesis. From the source of protein, it can be mainly divided into vegetable protein and animal protein, and from the processed form, it can be mainly divided into solid powder and liquid beverage.

1.1 Plant-based protein

Bean protein is a high-quality protein, containing high lysine, low content of sulfur-containing amino acids such as methionine and tryptophan, and high nutritional value. The protein content in tofu can reach 16.2%, and the fat The substance content is appropriate.

Soybean Peptide is a soybean sports supplement developed by using purified soybean protein powder or fermented bean dregs as raw materials, and using a compound enzymatic hydrolysis method to enzymatically hydrolyze macromolecular proteins into polypeptides. Soybean peptides can effectively remove the beany smell of soybean protein after enzymatic hydrolysis processing, greatly improve the taste of the eaters, and improve the instability and non-absorbability of soybean protein.

In order to enrich the nutritional types of protein and improve the taste of beverages, a variety of vegetable proteins can be mixed to prepare composite beverages, such as black soybean and walnut composite vegetable protein beverages.

1.2 Animal protein

Milk is a well-known health food. Whey protein is a kind of protein with high nutritional value existing in bovine milk whey. It is rich in essential amino acids and has a complete range and a moderate proportion.
Whey protein contains a variety of nutritional proteins, due to its non-clotting properties under acidic conditions and its high concentration of branched-chain amino acids for muscle tissue growth and repair—leucine, isoleucine, and valine. Utilization efficiency is higher than that of free amino acids.

Protein bars mainly use high-quality whey protein as raw materials, and are solid high-protein products configured in proportion to dietary fiber and probiotics.

Efficacy of Protein Nutraceuticals for Athletes

Protein nutritional food has many effects on athletes, which are embodied in the following aspects.

2.1 Muscle-building effect

Because protein is the source of life and the basic component of muscle, protein nutritional food has a better effect of increasing muscle.

The study found that consuming beef protein powder can significantly increase the muscle content of athletes and improve the muscle strength of athletes’ legs. Nutritional supplement protein has the function of being easily absorbed and promoting the synthesis of muscle fibers, so as to achieve the effect of increasing muscle and repairing muscle micro-damage.

2.2 Relieve exercise-induced fatigue

Protein nutritional foods generally have the function of scavenging free radicals and reducing serum urea nitrogen, thereby alleviating exercise-induced fatigue.

Human exercise fatigue is related to the content of branched-chain amino acids in human blood. The existence of branched-chain amino acids can reduce the generation of free radicals and weaken the sensitivity of the central fatigue nerve, thereby achieving the effect of relieving fatigue.

2.3 Improve immune function

Protein foods can provide rich immunoglobulins for the human body, so as to achieve the function of enhancing the immunity of athletes.

Whey protein can provide athletes with sufficient cysteine, increase the number of monocytes, and improve the immune function of the body.
