Protein additives: which is better for athletes?
Section 1: Protein – the basis of sports nutrition
1.1. The role of protein in the organization of muscle synthesis: Protein, or protein, is a cornerstone of muscle growth and restoration, especially for athletes whose bodies are subjected to increased physical stress. Muscle synthesis, the process of building new muscle fibers and the restoration of damaged, directly depends on the availability of amino acids, the construction blocks of protein. During training, muscle fibers are subjected to microtrauma. Protein consumed after training provides the necessary amino acids to “heal” these microtraumas and stimulates the adaptation process, which leads to an increase in the strength and size of the muscles. Without a sufficient amount of protein, the body will not be able to effectively recover, which can lead to a slowdown in progress, overtraining and increased risk of injuries. Various types of physical activity impose different requirements for protein consumption. For example, for power sports, such as heavy athletics and bodybuilding, more protein is required than for sporting endurance, such as long -range running. The intensity and duration of training also affect the need for protein.
1.2. Assessment of the need for protein for athletes: Determining the optimal amount of protein for an athlete is a difficult task that depends on many factors, including the sport, intensity of training, training experience, gender, age and general health. The general recommendation for athletes striving to increase muscle mass is from 1.6 to 2.2 grams of protein per kilogram of body weight per day. Athletes involved in endurance sports may require 1.2 to 1.7 grams of protein per kilogram of body weight per day to restore damaged muscles and maintain overall health. It is important to note that these values are indicative and may require individual adjustments. The quality of the protein consumed should be taken into account. Proteins containing a complete set of essential amino acids are considered better and more effective for muscle synthesis. The uniform distribution of protein consumption during the day, with an emphasis on meals after training, contributes to optimal restoration and growth of muscles. Exceeding the recommended dosage of protein does not lead to additional muscle growth and can have a negative effect on the kidneys and other organs.
1.3. Sources of protein: food vs. Additives: Protein can be obtained from various sources, both from whole products and from protein additives. Whole products, such as meat, fish, poultry, eggs, dairy products, legumes and nuts, are excellent sources of protein and contain additional nutrients, such as vitamins, minerals and fiber. However, in some cases, especially with intensive training or calorie restrictions, it can be difficult to get the required amount of protein only from food. Protein additives, such as serum protein, casein, soy protein and vegetable proteins, can be a convenient and effective way to fill the protein deficiency in the diet. They are easily absorbed, quickly digested and available in various forms, such as powders, bars and drinks. Protein additives should not replace good nutrition, but serve as an addition to a balanced diet. The choice between whole products and protein additives depends on individual preferences, dietary restrictions, budget and training goals.
Section 2: Types of protein additives and their properties
2.1. Whelm protein: Fast and effective: Serum protein is one of the most popular and studied types of protein additives. It is obtained from serum, a by -product of cheese production. Serum protein is characterized by a high speed of assimilation, rich in amino acid composition, especially high leicin content, amino acid, playing a key role in stimulating muscle synthesis. There are various forms of serum protein:
- Wastein serum concentrate (WPC): Contains from 30% to 80% protein. It is the most affordable in price, but may contain a certain amount of lactose and fats.
- Wastein protein isolate (WPI): Contains more than 90% of protein. It undergoes additional processing to remove lactose and fats, which makes it suitable for people with intolerance to lactose and those who seek the maximum protein consumption with a minimum number of calories.
- Hydrolysis of serum protein (WPH): The process of hydrolysis takes place, in which protein is split into smaller peptides, which provides even faster assimilation. The hydrolyzate of serum protein is often used in sports nutrition for quick recovery after training.
Serum protein is especially effective for taking after training, when the body needs a quick source of amino acids for the restoration and growth of muscles.
2.2. Casein: slow assimilation for long -term recovery: Casein is another protein obtained from milk. Unlike serum protein, casein is absorbed slowly, ensuring the gradual flow of amino acids into the blood for several hours. This makes it ideal for taking before bedtime, when the body is at rest and needs a long nutrition of muscles. Casein helps to reduce catabolism (muscle destruction) at night and improves recovery. There are two main forms of casein:
- Micellar casein: The most common form of casein, retaining its natural structure. It is absorbed very slowly and provides long -term receipt of amino acids.
- Calcium casein: The processed form of casein, which is absorbed a little faster than micellar casein.
Casein is often used as a replacement for food intake or as an additive to a diet to increase the total protein consumption.
2.3. Soy protein: a plant version for vegetarians and vegans: Soy protein is a plant protein obtained from soybeans. It is a full -fledged protein containing all essential amino acids. Soy protein is a great option for vegetarians, vegans and people with lactose intolerance. It also contains isoflavons, plant compounds with antioxidant properties. There are various forms of soy protein:
- Soy protein concentrate: Contains about 70% protein.
- Soy protein isolate: Contains more than 90% of protein.
- Textured soy protein (TSP): Used as a substitute for meat.
Soy protein can be used to maintain muscle growth and recovery, as well as to improve the general state of health. However, some studies show that soy protein can influence hormonal background in men, so its consumption should be limited.
2.4. Plant proteins (pea, rice, hemp): In recent years, the popularity of plant proteins has increased significantly. Pea protein, rice protein and hemp protein are only some of the available plant options. Each of them has its own unique amino acid profile and properties.
- Pea protein: A good source of amino acids with an extensive chain (BCAA), especially lysine. It is easily absorbed and suitable for people with sensitivity to lactose and gluten.
- Rice protein: Contains a moderate amount of protein and is a good source of cysteine and methionine. However, it contains less lysine than other plant proteins.
- Hemp protein: Contains all essential amino acids, as well as fiber and omega-3 fatty acids. It has a pleasant nutty taste.
Plant proteins are often used in mixtures to provide a complete amino acid profile. They are an excellent choice for vegetarians, vegans and people striving for a more environmentally friendly lifestyle.
2.5. Protein mixtures: an integrated approach to restoration: Protein mixtures are combinations of various types of protein, designed to ensure both quick and slow receipt of amino acids into the body. They often contain serum protein, casein, soy protein and other plant proteins. Protein mixtures can be more effective for the restoration and growth of muscles than individual types of protein, since they provide a longer and uniform flow of amino acids. They can also contain additional ingredients, such as creatine, glutamine and BCAA, to improve sports results. Protein mixtures are suitable for receiving at any time of the day, depending on the composition and goals of training.

Section 4: How to choose the right protein supplement
4.1. Definition of goals and needs: Before choosing a protein supplement, it is important to clearly define your goals and needs. If your goal is an increase in muscle mass, then serum protein, casein or protein mixture may suit you. If you are a vegetarian or vegan, then you should pay attention to soy protein or plant proteins. If you have lactose intolerance, then you should choose isolate serum protein or plant proteins. It is also important to take into account the intensity of training and the general diet.
4.2. Studying composition and food value: Carefully study the composition of the protein additive before buying it. Pay attention to the amount of protein on a portion, amino acid profile, the content of sugar, fats and carbohydrates. Avoid additives containing artificial flavors, dyes and sweeteners. Choose additives with a proven reputation and positive reviews.
4.3. Accounting for individual characteristics of the body: Each organism is unique, and what is suitable for one person may not be suitable for another. Consider your individual characteristics, such as allergies, intolerance and diseases. If you have any doubts, consult a doctor or nutritionist.
4.4. Selecting the form of release (powder, bar, drink): Protein additives are available in various forms of release, such as powders, bars and drinks. Powers are most convenient for cooking protein cocktails and adding to food. Bars are a convenient snack on the road or after training. Drinks are a ready -made option, but they can contain more sugar and additives. The choice of release form depends on your preferences and lifestyle.
4.5. Reputation manufacturer and certification: Choose protein additives from well -known manufacturers with a good reputation. Make sure that the product has passed certification and complies with quality standards. Pay attention to the reviews of other consumers.
Section 5: How to take protein additives correctly
5.1. Determining the optimal reception time: The time of taking a protein supplement depends on the type of protein and training goals. Wastein protein is best taken after training for rapid restoration and stimulation of muscle synthesis. Casein is best taken before bedtime to prevent catabolism and ensure prolonged receipt of amino acids. Protein mixtures can be taken at any time of the day. It is important to distribute protein consumption evenly during the day.
5.2. Determining the optimal dosage: The optimal dosage of protein additive depends on your protein need, type of protein and training goals. The general recommendation for athletes is from 1.6 to 2.2 grams of protein per kilogram of body weight per day. Start with a small dosage and gradually increase it until you reach the optimal level.
5.3. A combination with other nutrients: For optimal restoration and growth of muscles, it is important to combine the consumption of protein with other nutrients, such as carbohydrates and fats. Carbohydrates provide energy for training and help transport protein into muscles. Fats are important for hormonal balance and overall health.
5.4. The importance of the water balance: When consuming a large amount of protein, it is important to maintain water balance. Protein has a diuretic effect, so you need to drink enough water to prevent dehydration.
5.5. Possible side effects and contraindications: In some cases, protein additives can cause side effects, such as bloating, gas formation, diarrhea and allergic reactions. People with diseases of the kidneys, liver and other organs should consult a doctor before taking protein additives.
Section 6: Protein for different sports
6.1. Protein for power sports (bodybuilding, weightlifting, powerlifting): For athletes involved in power sports, protein plays a key role in muscle growth and restoration. It is recommended to consume from 1.8 to 2.2 grams of protein per kilogram of body weight per day. Serum protein and casein are excellent options for admission after training and before bedtime, respectively. Creatine and glutamine can also be useful for improving sports results.
6.2. Protein for sporting endurance (running, swimming, cycling): For athletes involved in endurance sports, protein is necessary to restore damaged muscles and maintain overall health. It is recommended to consume from 1.2 to 1.7 grams of protein per kilogram of body weight per day. Protein mixtures and plant proteins are good options for admission during the day. BCAA can also be useful to prevent catabolism.
6.3. Protein for command sports (football, basketball, volleyball): For athletes involved in team sports, protein is necessary to maintain strength, endurance and restoration. It is recommended to consume from 1.4 to 1.8 grams of protein per kilogram of body weight per day. Serum protein and protein mixtures are good options for reception after training and during the day.
6.4. Protein for women sportsmen: Women athletes also need sufficient protein for the growth and restoration of muscles. The recommended dosage of protein for women athletes is the same as for male sportsmen-from 1.6 to 2.2 grams of protein per kilogram of body weight per day. Serum protein, casein and plant proteins – all these are suitable options.
6.5. Protein for elderly athletes: With age, the need for protein increases, since the body becomes less effective in protein synthesis. Older athletes are recommended to consume from 1.2 to 1.5 grams of protein per kilogram of body weight per day to maintain muscle mass and strength. Serum protein and protein mixtures are good options for elderly athletes.
Section 7: Myths and delusions about protein additives
7.1. Myth: Protein is harmful to the kidneys: This myth is based on outdated research. In healthy people, the consumption of a large amount of protein does not have a negative effect on the kidneys. However, people with kidney diseases should limit the intake of protein.
7.2. Myth: Protein causes weight gain: Protein itself does not cause weight gain. Weight gain occurs due to an excess of calories. Protein, on the contrary, can help in weight loss, as it promotes saturation and increases metabolism.
7.3. Myth: Protein is needed only by bodybuilders: Protein is necessary for all athletes, regardless of the sport. It is important for restoration of muscles, maintaining strength and endurance.
7.4. Myth: more protein – more muscles: Exceeding the recommended dosage of protein does not lead to additional muscle growth. The body can only learn a certain amount of protein at a time. Excess protein is excreted from the body or transformed into fat.
7.5. Myth: Protein additives replace good nutrition: Protein additives should not replace good nutrition. They should serve as an addition to a balanced diet rich in vitamins, minerals and fiber.
Section 8: New Research and Trends in the field of protein nutrition
8.1. Personalized approach to protein consumption: Modern studies show that the optimal dosage of protein depends on the individual genetic characteristics and metabolic processes. New methods for determining the individual need for protein are developed.
8.2. Protein and intestinal microbia: Studies show that protein can affect the composition and function of the intestinal microbioma. Some types of protein, such as casein and soy protein, can contribute to the growth of certain types of bacteria in the intestine.
8.3. The effect of protein on the hormonal background: Studies continue to study the effect of protein on hormonal background, especially in women. Some studies show that soy protein can influence the level of estrogen.
8.4. Development of new types of protein additives: New types of protein additives are developed, such as insect proteins and algae proteins. These proteins can become alternative sources of protein in the future.
8.5. Improving the taste and texture of protein additives: Protein additive manufacturers are constantly working on improving the taste and texture of their products. New flavors and additives are being developed that make protein additives more pleasant use.
