Abstract
Dragon boat is an excellent traditional national sport in China, with excellent fitness results. Based on the country’s strong support for traditional national sports, the dragon boat has developed into a traditional national sport with specific influence and popularity among the masses. Eggshell membrane (ESM) has the effect of relieving arthritis, joint pain, and joint stiffness. The supplementary ESM’s preventive effect on sports injuries has attracted people’s attention. Based on this, this article builds a sports injury prediction model under artificial intelligence and big data monitoring to accurately predict the injuries suffered by athletes, provide help to reduce athletes’ injuries during training, and promote the development of dragon boat sports. This article selects 20 members of a dragon boat team from a university and randomly divides them into a control group (supplement of equal amounts of whey protein), a normal group, an ESM low-dose group (26 mg/kg bw/d), and an ESM high-dose group (52 mg/kg bw/d), with 5 people in each group. The subjects were subjected to downhill exercise and immune stimulation experiments. Among them, the subjects in the control group performed downhill exercise for 12 hours, and they were tested for lactic acid (LAC), lactate dehydrogenase (LDH), urea, malondialdehyde (MDA), hemoglobin (Hb), blood creatinine (CRE), and other related physical and chemical indicators. The other three groups of subjects did not take low-dose and high-dose ESM for 7 consecutive days and were injected with lipopolysaccharide on the 8th day for immune stimulation and tested for interferon (IFN-γ), tumor necrosis factor (TNF-α), interleukins (IL-1β, IL-6, and IL-10), and other related cytokines. The results show that oral egg membrane protein (ESM) can reduce subjects’ serum LAC, LDH, urea, MDA, Hb, and CRE concentration. In addition, the ESM can reduce the expression of proinflammatory factors IL-1β and TNF-α, while increasing the expression of anti-inflammatory factor IL-10, which provides clinical data for the clinical use of ESM as a supplement for sports injury or for relieving arthritis symptoms. The study shows that egg membrane protein has a protective effect against sports injury and may be regulated by inflammatory factors.
Highlights
Sports injury usually occurs during intense or excessive exercise
Analysis of Amino Acid Composition of Egg Membrane Protein. 19 kinds of amino acids were detected in eggshell membrane, including serine (Ser), glycine (Gly), methionine (Met), histidine (His), isoleucine (Ile), tryptophan (Tyr), phenylalanine (Phe), hydroxylysine (OH-Lys), hydroxyproline (OH-Pro), threonine ( r), proline (Pro), cysteine (Cys), aspartic acid (Asp), lysine (Lys), leucine (Leu), valine (Val), glutamic acid (Glu), alanine (Ala), and arginine (Arg), which were the most abundant amino acids. e contents of glutamic acid (Glu), cysteine (Cys), and proline (Pro) accounted for 12.9%, 9.1%, and 8.4%, respectively. e content of hydroxyproline (OH-Pro) was 0.5% and 1.2%, respectively, as shown in Table 1 and Figure 1
The concentrations of lactic acid (LAC), urea, and malondialdehyde (MDA) in serum supplemented with Eggshell membrane (ESM) (52 mg/kg bw/d) were found to be lower than those in the control group, and the difference was significant (P < 0.05)
Summary
Sports injury usually occurs during intense or excessive exercise. Once a sports injury is caused, it will affect the physical condition of the athletes and affect their mental health [1]. After the occurrence of sports injury, it generally depends on the self-healing of the damaged tissue, and the recovery generally depends on elastin and collagen in the tissue. At this time, athletes usually need to strengthen nutritional supplements, such as high-quality protein, e.g., soy protein and milk protein. Egg membrane protein is a kind of egg inner membrane protein, which is rich in collagen and elastin, accounting for about 15%, and the ratio of them is close to 1 :1. Egg membrane is a kind of traditional Chinese medicine, which has good medicinal and health value
