Sports nutrition: dietary supplements

Sports nutrition: dietary supplements – a detailed guide for biologically active additives for athletes

Chapter 1: Fundamentals of sports nutrition and the role of dietary supplements

Sports nutrition is an extensive category of products designed to optimize physical performance, improve the restoration and achievement of sports goals. Unlike conventional foods, sports nutrition usually has a higher concentration of certain nutrients specially selected to meet the needs of athletes and active people. Dietary supplements, or biologically active additives, are an important part of sports nutrition, representing concentrated sources of nutrients or other substances with physiological effects designed to supplement the diet. Understanding the role of dietary supplements in the context of sports training and general health is crucial for making reasonable decisions on their use.

1.1 macro- and micronutrients in sports

To maintain optimal performance and restoration, athletes need to consume a sufficient amount of macro- and micronutrients. Macronutrients are proteins, fats and carbohydrates that provide the body with energy and building blocks. Proteins are important for the restoration and growth of muscles, carbohydrates are the main source of energy, and fats are necessary for hormonal regulation and assimilation of fat -soluble vitamins. Micronutrients, such as vitamins and minerals, are involved in many metabolic processes, including energy metabolism, immune function and tissue restoration. The lack of even one micronutrient can adversely affect sports results.

• Squirrels: Recommendations for protein consumption for athletes vary depending on the sport, intensity of training and individual characteristics, but usually amount to 1.2 to 2.2 grams of protein per kilogram of body weight per day.
• Carbohydrates: Carbohydrates are the main source of fuel for muscles during training. Carbohydrate consumption should correspond to energy costs and can vary from 3 to 12 grams per kilogram of body weight per day.
• Fat: Fats are important for hormonal regulation, assimilation of fat -soluble vitamins and providing energy at rest and under low -intensity loads. It is recommended to consume from 20% to 35% of fat calories, giving preference to unsaturated fats.
• Vitamins and minerals: Athletes may need more certain vitamins and minerals, such as group B vitamins, vitamin D, iron, calcium and magnesium, due to the increased need associated with intense training.

1.2 Definition and classification of dietary supplements

Bades, according to the definition, are concentrated sources of nutrients or other substances with a physiological effect, designed to supplement the diet. They are available in various forms, including tablets, capsules, powders, liquids and bars. Bades may contain vitamins, minerals, amino acids, herbs, plant extracts, enzymes, probiotics and other substances. Classification of dietary supplements can be carried out according to various criteria, including:

• Composition: Vitamin-mineral complexes, protein additives, amino acid complexes, creatine, plant extracts, etc.
• Purpose: For a set of muscle mass, to increase endurance, to accelerate recovery, to burn fat, to maintain joint health, etc.
• Output form: Tablets, capsules, powders, liquids, bars, etc.

1.3 Bad regulation: risks and safety

The regulation of dietary supplements varies significantly in different countries. In some countries, such as the United States, dietary supplements are regulated as food, and not as medicines, which means that manufacturers are not required to prove their effectiveness or safety before the market. This can lead to risks associated with the quality, purity and composition of dietary supplements. Some dietary supplements may contain prohibited substances that are not indicated on the label, or be contaminated with toxic substances. It is important to choose dietary supplements from reliable manufacturers who undergo third -party quality and safety checks.

1.4 The value of an individual approach to the use of dietary supplements

The effectiveness and safety of dietary supplements depend on the individual characteristics of the body, health status, sport, intensity of training and goals. Before you start taking any dietary supplements, you need to consult a doctor or a qualified sports nutritionist. They can evaluate your individual needs and help you choose the most suitable and safe additives. You should not rely on dietary supplements as a replacement for a balanced diet and a healthy lifestyle. Bades should only be used as an addition to the diet, and not as its basis.

Chapter 2: Popular dietary supplements for athletes and their effectiveness

There are many dietary supplements intended for athletes, each of whom has its own characteristics, advantages and disadvantages. It is important to understand what additives have a scientific evidence base and which are marketing tricks. In this chapter, we will consider the most popular and studied dietary supplements for athletes and evaluate their effectiveness based on scientific data.

2.1 protein: serum, casein, soy and others

Protein is one of the most popular and important dietary supplements for athletes, especially for those who are engaged in power sports. Protein is necessary for the restoration and growth of muscles, as well as to maintain overall health. There are several different types of protein, each of which has its own characteristics and advantages:

• Wastein protein: A rapidly absorbed protein, which is ideal for admission after training, to quickly deliver amino acids to the muscles. There are several forms of serum protein, including concentrate, isolate and hydrolyzate, which differ in the degree of processing and protein content.
• Casein: Slowly absorbed protein, which is ideal for admission before bedtime, to provide muscles with amino acids during the night. Casein can also be useful for maintaining a feeling of satiety and reducing appetite.
• Soy protein: Vegetable protein, which is a good alternative to vegetarians and vegans. Soy protein contains all the necessary amino acids and can be effective for the restoration and growth of muscles.
• Egg protein: Protein with high biological value, which is well absorbed by the body. Egg protein contains all the necessary amino acids and can be effective for the restoration and growth of muscles.
• Plant proteins (pea, rice, hemp, etc.): Alternative sources of protein for vegetarians and vegan. Combining various plant proteins can provide a complete amino acid profile.

2.2 creatine: monohydrate, ethyl ether, hydrochloride

Creatine is one of the most studied and effective additives for increasing strength and muscle mass. Creatine increases the reserves of creatine phosphate in the muscles, which is used to produce energy during high -intensity exercises. There are several different forms of creatine, including:

• Creatine Monogidrate: The most common and well -studied form of creatine. Creatine Monohydrate has proven its effectiveness in increasing strength, muscle mass and endurance.
• Creatine Ethyl ether: The form of creatine, which, claimed, is better absorbed by the body, but scientific studies have not confirmed this statement.
• Creatine Hydrochloride (HCL): The shape of creatine, which dissolves in water is better than creatine monohydrate. Some studies show that HCL creatine can be more effective in smaller doses, but additional studies are needed.

2.3 BCAA: Laicin, isoleycin, Valin

BCAA (amino acids with an extensive chain) is a group of three essential amino acids: leucine, isolacin and valine. BCAA play an important role in protein synthesis, restoration of muscles and decreasing muscle fatigue. BCAA can be useful for athletes involved in intensive training, especially during the periods of calorie restrictions.

2.4 glutamine

Glutamine is an amino acid that plays an important role in immune function, muscle restoration and intestinal health. During intensive training, the level of glutamine in the body may decrease, which can lead to weakening immunity and slowing down recovery. The intake of glutamine can help support the immune function and accelerate recovery after training.

2.5 Beta-Alanine

Beta-Alanin is an amino acid that increases the level of carnosine in the muscles. Carnosine is a buffer that helps neutralize lactic acid in the muscles, which can improve endurance during high -intensity exercises. Beta-Alanin can be useful for athletes involved in sports, requiring high endurance, such as running, swimming and cycling.

2.6 Caffeine

Caffeine is a stimulant that can improve physical and mental performance. Caffeine can increase energy, improve concentration, reduce fatigue and increase endurance. Caffeine should be consumed moderately, since high doses can cause side effects, such as anxiety, insomnia and stomach disorder.

2.7 omega-3 fatty acids

Omega-3 fatty acids are indispensable fats that play an important role in the health of the heart, brain and joints. Omega-3 fatty acids can help reduce inflammation, improve blood circulation and maintain joint health. Athletes are recommended to consume a sufficient amount of omega-3 fatty acids to maintain general health and improve recovery after training.

2.8 vitamin D

Vitamin D is a fat -soluble vitamin that is important for the health of bones, immune function and muscle strength. Vitamin D deficiency is a common occurrence, especially in the winter months. Athletes are recommended to check the level of vitamin D and take additives, if necessary.

2.9 Magnesium

Magnesium is a mineral that is involved in many metabolic processes, including energy metabolism, muscle function and bone health. Magnesium deficiency can lead to muscle seizures, fatigue and a decrease in performance. Athletes are recommended to consume a sufficient amount of magnesium to maintain the optimal function of muscles and energy metabolism.

2.10 iron

Iron is a mineral that is necessary to transport oxygen in the blood. Iron deficiency can lead to fatigue, weakness and reduction in performance. It is recommended to regularly check the level of iron and take additives, if necessary.

Chapter 3: Bad for specialized sports purposes

In addition to general additives designed to maintain general health and performance, there are dietary supplements developed to solve specific sports problems, such as increasing muscle mass, weight loss, improvement of endurance or supporting joints.

3.1 dietary supplement to increase muscle mass

• HMB (beta-gidroxy-beta-methyllbut): Metabolite Leucine, which can help reduce muscle breakdown and increase protein synthesis. HMB can be useful for novice athletes or during periods of intense training.
• Testosterone booster: Additives, which are claimed to increase testosterone levels in the body. However, the effectiveness of most testosterone booster has not been proved by scientific research. It is important to be careful when using these additives, as they can have side effects.
• Estrogen-blockers: Additives, which are claimed, block the effect of estrogen in the body. These additives can be dangerous and not recommended to use without consulting a doctor.

3.2 dietary supplements for weight loss

• Thermogenics: Additives that increase thermogenesis (heat production in the body), which can lead to an increase in calories and weight loss. Thermogenics usually contain caffeine, synephrine and other stimulants. It is important to use thermogenics with caution, as they can cause side effects, such as anxiety, insomnia and stomach disorder.
• Fathers: Additives, which are claimed, increase fat burning in the body. The effectiveness of most fat burners has not been proved by scientific research. Some fat burners may contain prohibited substances or be polluted by toxic substances.
• L-Carnitin: An amino acid that plays an important role in the transportation of fatty acids to mitochondria, where they are used for energy production. L-carnitine can help increase fat burning, but its effectiveness depends on the individual characteristics of the body and the intensity of training.
• CLA (conjugated linoleic acid): Fatal acid, which can help reduce the fat mass and increase muscle mass. The effectiveness of CLA in weight loss has not been proved by scientific research.

3.3 dietary supplements to improve endurance

• Erythropoetin (EPO) stimulants (legal): Some additives can indirectly stimulate the production of EPOs, for example, Arginine and vitamin C. However, their effect is much weaker than that of synthetic EPO.
• Buffer supplements (bicarbonate of sodium): They help neutralize lactic acid, delaying fatigue at anaerobic loads.
• Iron preparations: Important for endurance athletes, especially for women, for maintaining the normal level of hemoglobin and oxygen transport.

3.4 dietary supplements to support joint health

• Glucosamine and chondroitin: Substances that are construction blocks of cartilage. Glucosamine and chondroitin can help reduce pain and inflammation in the joints, as well as improve their function.
• Collagen: Protein, which is the main component of connective tissue, including cartilage, ligaments and tendons. Collagen can help improve joint health, reduce pain and inflammation, as well as increase their flexibility.
• MSM (methyl sulfonylmetatan): The organic compound of sulfur, which can help reduce pain and inflammation in the joints, as well as improve their function.
