Description

Technical Field

[0001] The present invention relates to the technical field of food and health food, and in particular to an excellent composition, preparation and application thereof for promoting muscle synthesis and enhancing muscle strength. Background Art

[0002] With the progress of society and the improvement of material living standards, health awareness and fitness culture are becoming more and more popular. Athletes, fitness enthusiasts and the elderly are paying more and more attention to how to enhance muscle strength and promote muscle synthesis through scientific methods. Promoting muscle synthesis and enhancing muscle strength is not only to build a strong body, but also to protect our physical and mental health. Scientific physical training is essential for muscle growth. At the same time, the appropriate amount of safe and effective nutritional supplements can better enhance the effect. The increase in muscle mass and strength can not only improve athletic performance, but also enhance the individual's ability to carry out daily activities and improve the quality of life.

[0003] In the field of nutrition, nutrients such as proteins, peptides, carbohydrates, creatine, and taurine have been reported to play an important role in muscle growth and repair. Traditional Chinese medicine and its extracts, which are both medicinal and edible, contain a variety of bioactive ingredients, and their role in strengthening physical fitness and improving health has gradually been confirmed by modern scientific research. In recent years, the use of the efficacy of natural plant ingredients to enhance muscle strength and flexibility, increase muscle endurance, and improve the ability to coordinate and control the various moving parts of the body has become a research direction. Existing muscle-building products focus on the supplementation of single ingredients such as protein and carbohydrates. In the early days, people mainly took in protein through food, but with the advancement of technology, products in the form of protein powder and protein bars have gradually become popular. Whey protein, milk protein, and soy protein have become mainstream products on the market due to their high biological value and easy absorption. Although these products have certain effects, the effect is no longer obvious after a period of supplementation.

[0004] With the in-depth research of nutrition science and the increase in sports nutrition needs, single-ingredient products can no longer meet the diverse needs. Some compound products also have defects such as unreasonable formulas, incomplete nutrition or poor absorption, resulting in low bioavailability of nutrients.

[0005] Therefore, it is particularly important to develop a compound formula that is more effective in improving muscle synthesis and enhancing muscle strength. Summary of the invention

[0006] In order to solve the problems existing in the prior art, the present invention is based on the theory of the homology of medicine and food, and obtains a comprehensive nutritional supplement with multiple components, multiple pathways and multiple targets through scientific matching. The composition not only takes into account the nutrients required for muscle synthesis, but also contains active substances that contribute to energy metabolism and muscle recovery. Through this comprehensive nutritional supplementation strategy, the present invention provides a safe and effective muscle promotion program, and the composition has a good taste and is easily accepted by the public.

[0007] In order to achieve the purpose of the present invention, the present invention provides a composition for promoting muscle synthesis and enhancing muscle strength, characterized in that the composition comprises the following raw materials in parts by weight: 10-30 parts of protein, 5-15 parts of peptides, 25-60 parts of carbohydrates, 5-15 parts of creatine, 0.5-2 parts of taurine, 5-20 parts of Dendrobium officinale powder, and 5-20 parts of burdock root powder.

[0008] Furthermore, the composition comprises the following raw materials in parts by weight: 10-20 parts of protein, 5-10 parts of peptides, 30-60 parts of carbohydrates, 5-10 parts of creatine, 0.5-1 parts of taurine, 5-10 parts of Dendrobium officinale powder, and 5-10 parts of burdock root powder.

[0009] Further preferably, the carbon-nitrogen ratio of the composition is 3:1.

[0010] Furthermore, the composition further comprises 1 to 5 parts of amino acids and / or 0.05 to 3 parts of vitamins and / or 0.01 to 2 parts of minerals; The amino acid is selected from at least one of valine, leucine and isoleucine, and the vitamin is selected from vitamin A, vitamin C, vitamin B1, vitamin B2, vitamin B6, vitamin B 12 , vitamin D3, vitamin E, vitamin K, folic acid, niacin, biotin, and calcium pantothenate, and the minerals include one or more of calcium salts, magnesium salts, iron salts, zinc salts, selenium salts, and manganese salts allowed for use in nutritional fortifiers listed in GB-14880-2012.

[0011] Further preferably, the selection of calcium salts includes but is not limited to calcium carbonate, calcium gluconate, calcium citrate and calcium hydrogen phosphate, the selection of magnesium salts includes but is not limited to magnesium carbonate, magnesium gluconate and magnesium chloride, the selection of iron salts includes but is not limited to ferric pyrophosphate, ferric citrate, ferrous fumarate and ferrous gluconate, the selection of zinc salts includes but is not limited to zinc gluconate, zinc citrate and zinc lactate, the selection of selenium salts includes but is not limited to sodium selenate, sodium selenite and selenium-enriched yeast, and the selection of manganese salts includes but is not limited to manganese gluconate, manganese carbonate and manganese citrate.

[0012] Furthermore, the protein is selected from at least one of concentrated whey protein, isolated whey protein, yeast protein, isolated soy protein, rice protein, and concentrated milk protein.

[0013] Further preferably, the protein consists of concentrated whey protein, isolated soy protein, isolated whey protein, yeast protein and rice protein.

[0014] Furthermore, the protein consists of concentrated whey protein, isolated soy protein, isolated whey protein, yeast protein and rice protein in a weight ratio of 1-50:1-40:1-10:1-10:1.

[0015] Furthermore, the peptides are selected from at least one of oyster peptides, collagen peptides, collagen tripeptides, soybean oligopeptides and chicken imidazole dipeptide.

[0016] Furthermore, the carbohydrate is selected from one or more of glucose, crystalline fructose, maltodextrin, maltooligosaccharide, isomaltooligosaccharide, isomaltulose, cyclodextrin, and D-ribose.

[0017] The present invention also provides an oral preparation for promoting muscle synthesis and enhancing muscle strength, characterized in that the raw materials include the composition of the present invention.

[0018] Furthermore, the oral preparation also includes food-acceptable excipients.

[0019] Furthermore, the oral preparation is a powder or a liquid preparation.

[0020] The present invention also provides a method for preparing the oral preparation, which specifically comprises: mixing the components according to weight, adding auxiliary materials, crushing and sieving, and mixing evenly.

[0021] Furthermore, a solvent may be added to prepare a liquid preparation.

[0022] The present invention also provides an application of the composition or the compound preparation in preparing a preparation for promoting muscle synthesis and enhancing muscle strength.

[0023] The effects of each component in the composition of the present invention are as follows: Protein is the basis of muscle synthesis, and amino acids are the key to muscle repair and growth. Synthesizing new proteins through amino acids can help muscle cells grow.

[0024] Peptides are small molecule protein fragments that can be quickly digested and absorbed, and their absorption rate is better than that of proteins and free amino acids. Peptides quickly enter the muscles, accelerating muscle growth and repair, thereby reducing muscle damage and promoting muscle recovery.

[0025] Creatine, as a common performance enhancer, can not only provide energy quickly, but also increase muscle strength and endurance. Creatine in muscles combines with phosphoric acid to form creatine phosphate, which is an important substance that quickly provides energy during muscle contraction. The creatine of the present invention can increase the creatine phosphate reserve in muscles, thereby improving muscle strength and endurance.

[0026] Carbohydrates are the main source of energy. The concept of gradient carbon water is adopted to match carbohydrates with different glycemic indexes. By taking advantage of their fast and slow energy supply rates, it can provide energy steadily and continuously, achieve the purpose of long-term energy supply, and thus better support muscle work and help muscle recovery and growth.

[0027] Taurine helps improve muscle strength and endurance. Its mechanism of action includes increasing calcium ion concentration in muscle cells, stimulating muscle contraction, and thus enhancing muscle strength. At the same time, taurine can also improve the efficiency of muscle oxygen utilization, reduce lactic acid accumulation, relieve oxidative stress in skeletal muscles after exercise, delay muscle fatigue, and thus enhance muscle endurance.

[0028] Dendrobium candidum contains rich active ingredients such as polysaccharides, dendrobium alkaloids and amino acids, which can enhance immunity, anti-oxidation, anti-inflammatory and other effects. These ingredients provide necessary nutritional support to strengthen physical fitness, improve concentration, relieve fatigue after exercise, and help promote muscle recovery and growth. The Dendrobium candidum powder used in this application is a commercially available raw material.

[0029] As a medicinal and edible herb, burdock root polysaccharide, the main active ingredient of burdock root, has multiple biological activities such as anti-oxidation, immune regulation, and anti-fatigue, and has a positive effect on muscle synthesis and muscle health. The burdock root powder used in this application is a commercially available raw material.

[0030] Amino acids, especially branched-chain amino acids, are important amino acids that participate in energy supply during long-term exercise. They can play a role by supporting tissue growth and repairing damaged muscle tissue, helping to improve muscle function and exercise performance, and have significant benefits for improving muscle strength and promoting muscle growth.

[0031] Vitamins and minerals are cofactors of many biochemical reactions and can participate in related metabolic reactions, thereby helping muscle synthesis and repair.

[0032] The beneficial effects of the present invention are as follows: modern nutrition science is combined with traditional Chinese medicine to develop a new composition that promotes muscle synthesis and enhances muscle strength. The composition not only contains nutrients such as protein, peptides, creatine, taurine, amino acids, vitamins, minerals, etc., but also adds Dendrobium officinale and burdock root, which have tonic value in traditional Chinese medicine theory. Dendrobium officinale powder and burdock root powder positively regulate the expression level of growth factor receptors in skeletal muscle tissue, and play a role in improving skeletal muscle cell proliferation. And the carbon water protein ratio of the composition is scientific, so that it has a suitable carbon nitrogen ratio, so as to more effectively promote the recovery of glycogen and the repair of muscles, and then help the recovery after exercise. The whole composition acts on muscles by providing the nutritional protein, energy source, energy reserve, maintenance of cell function, and promotion of muscle recovery required for muscle synthesis, aiming to effectively improve muscle synthesis efficiency and muscle strength performance through multi-component, multi-pathway, and multi-target synergy.

Effect test examples of the composition of the present application 1. Experimental Animals and Grouping

[0050] 80 SD female rats weighing 200-220g were taken and fed freely. After a one-week adaptation period, the experiment was conducted. The rats were randomly divided into 10 groups according to the weight matching principle, namely, a normal blank group, a model control group, Example 1-4 groups, and Comparative Example 1-4 groups, with 8 rats in each group. 2. Establishment of Animal Model

[0051] The rats in the model control group, the embodiment group and the comparative group were housed in separate cages, and their tails were suspended from the adapter ring at the top of the cage using medical tape to achieve a 30° suspension between the floor and the body with the hind limbs, and the forelimbs were free to walk, and were suspended for 14 consecutive days, and were fed and watered daily, while the blank group was not suspended. The implementation group and the comparative group were gavaged with the corresponding composition at a dose of 180 mg / kg body weight at regular intervals every day, and the blank group and the model control group were gavaged with the solvent. 3. Testing of experimental indicators

[0052] (1) After the animal was anesthetized intraperitoneally, the right calf was dissected, the muscles were separated and exposed, and the main arteries and veins were not damaged. The distal muscle tendons were cut and connected to the transducer with a zero-number wire. The maximum tension of the isometric contraction and the maximum tension of the tetanic contraction were tested according to the following method and steps. The blood flow of the muscles was ensured to be unobstructed throughout the experiment, and physiological buffer was continuously added.

[0053] The method for determining the maximum tension of muscle isometric contraction is as follows: an electrode stimulator is used to output pulses with a pulse width of 25ms, an interval of 2s and a voltage of 5V for stimulation. The muscle is gradually stretched in 0.1mm increments to the initial length position when the isometric contraction tension is maximum, and the maximum isometric contraction tension is measured.

[0054] Method for determining the maximum tension of muscle tetanic contraction: The electrical stimulator outputs pulse stimulation with a pulse width of 20ms, an interval of 40s and a voltage of 5V to induce high-frequency tetanic contraction of the muscle. The tetanic contraction curve is recorded to obtain the maximum tension value.

[0055] (2) After measuring muscle function through the above steps, weigh the soleus muscle and record the weight. Use filter paper to absorb excess water before weighing. 4. Experimental results analysis

[0056] (1) The muscle weight of rats in each test group during the simulated weightlessness period was compared and analyzed to evaluate the improvement effect of each composition of the present invention on muscle weight. The results are shown in Tables 1 and Figure 1-2 shown.

[0057] Table 1 Effects of the soleus muscle weight and muscle weight to body weight ratio in hindlimb-suspended rats (MEAN±SD, n=8)

[0058] The results showed that the weight loss and muscle weight to body weight ratio of the rats in the model control group were significantly reduced compared with those in the blank group, indicating that the soleus muscle of the rats had obvious atrophy after long-term hind limb suspension. Compared with the model control group, the muscle weight and muscle weight to body weight ratio of the soleus muscle in the embodiment group were significantly increased ( P <0.01). After the control group replaced and adjusted the Chinese medicine extract, omitted the peptides, or adjusted the ratio of protein to carbohydrate components, the muscle weight and muscle weight / body weight of the model control group were also improved to a certain extent, but the improvement effect was not obvious. In Example 1, tonic ginseng powder was used instead of dendrobium powder, or the control group added yin-nourishing and kidney-tonifying polygonatum powder, and the effect of the comparative combination was not significantly improved. It can be seen that the combination of dendrobium powder, burdock root powder and nutrients can achieve better results, and the effect of comparative example 4 after adjusting the ratio of protein to carbohydrate components was also significantly reduced. It can be seen that the composition of the present application can effectively alleviate the reduction of rat muscle weight through the reasonable synergistic combination of multiple components under scientific proportions, and achieve the effect of effectively promoting muscle synthesis.

[0059] (2) By selecting the isometric contraction tension and tetanic contraction tension observation indicators of soleus muscle, the effects of hind limb suspension rats and gavage of the corresponding composition on the contractile function of the soleus muscle were studied. The results are shown in Tables 2 and Figure 3-4 shown.

[0060] Table 2 Effects on the maximum contraction tension of soleus muscle in hindlimb hanging rats (MEAN±SD, n=8)

[0061] The results showed that the maximum tension values ​​of isometric contraction and tetanic contraction in the model control group were significantly reduced compared with the normal control group, and the contractile function of the hind limb hanging rats was significantly affected. The group of the embodiment of the present invention had a significant increase compared with the model control group ( P <0.01), among which Example 2 has the best effect. The Example compositions can effectively inhibit the decrease in muscle mechanical tension of animals caused by simulated weightlessness. Although the maximum tension of the comparative group is also improved to a certain extent compared with the model group, there is no significant difference in the effect. This shows that the synergistic function of the components of the composition of the present application is more significant, which can effectively counteract the decrease in muscle tension caused by the disuse of the soleus muscle, thereby helping to improve muscle contraction ability and enhance muscle strength.

[0062] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
