The effect of sports nutrition on hormonal background when gaining mass

Chapter 1: Hormonal system and muscle tissue hypertrophy

1.1. Review of the endocrine system and its role in metabolism

The endocrine system, a complex network of glands producing and secreting hormones, plays a key role in the regulation of almost all physiological processes in the body. Hormones, acting as chemical messengers, move around the bloodstream and associate with target cells, having a deep effect on metabolism, growth, development, reproductive function, mood and sleep.

The key glands of the endocrine system include the pituitary gland, thyroid gland, adrenal glands, pancreas and sex glands (ovaries in women and testicles in men). Each gland produces a certain set of hormones that interact with each other in a complex feedback system, supporting homeostasis.

In the context of the set of muscle mass, hormones play a decisive role in the regulation of the metabolism of proteins, carbohydrates and fats, as well as in the stimulation of the anabolic processes necessary for hypertrophy of muscle fibers. Violations in hormonal balance can seriously complicate the process of setting muscle mass and even lead to catabolism.

1.2. The main hormones affecting muscle growth: testosterone, growth hormone, insulin, cortisol

• Testosterone: This steroid hormone, mainly produced by testicles in men and in small quantities in women, is a powerful anabolic agent. It contributes to the synthesis of protein, an increase in muscle mass, a decrease in fat mass and an increase in bone density. Testosterone also plays an important role in the development of secondary sexual characteristics in men, such as deepening voice and hair growth on the face. The mechanism of action of testosterone includes binding with androgenic receptors in muscle cells, which leads to the activation of the genes responsible for the synthesis of protein.
• Growth hormone (GR): GR produced by the pituitary gland stimulates the growth of bones and cartilage, and also contributes to the synthesis of protein and fat recycling. It has an indirect effect on muscle growth through an insulin-like growth factor 1 (IFR-1), which is produced by the liver in response to the stimulation of gr. IFR-1, in turn, stimulates the proliferation and differentiation of muscle cells.
• Insulin: This hormone, produced by the pancreas, plays a key role in regulating the level of glucose in the blood. It contributes to the transport of glucose from the blood to the cells, where it is used to produce energy or stocks in the form of glycogen. Insulin also has an anabolic effect, stimulating protein synthesis and suppress its decay. However, it is important to note that a chronically increased level of insulin can lead to insulin resistance and an increase in fat mass.
• Cortisol: This hormone, produced by the adrenal glands, is often called the “stress hormone.” It is released in response to physical or emotional stress and plays an important role in regulating the level of glucose in the blood, immune function and inflammatory processes. Cortisol has a catabolic effect, contributing to the decay of protein and glycogen to provide the body with energy in stressful situations. The chronically increased level of cortisol can interfere with the set of muscle mass and even lead to its loss.

1.3. Hormonal regulation mechanisms: positive and negative feedback

Hormonal regulation is carried out using complex feedback mechanisms that allow maintaining homeostasis and adapt to changing environmental conditions.

• Negative feedback: This is the most common regulation mechanism, in which an increase in hormone levels inhibits its further production. For example, an increase in the level of testosterone in the blood suppresses the release of gonadotropin-releasing hormone (GNRG) from the hypothalamus, which, in turn, stimulates the release of luteinizing hormone (LH) from the pituitary gland. LH stimulates the production of testosterone with testicles. Thus, an increase in testosterone levels leads to a decrease in LH production and, therefore, a decrease in testosterone production.
• Positive feedback: This is a less common regulation mechanism, in which an increase in hormone levels stimulates its further production. For example, during ovulation, an increase in estrogen levels stimulates the release of LH from the pituitary gland, which leads to an even greater increase in estrogen levels and, ultimately, ovulation.

Understanding the mechanisms of hormonal regulation is important for understanding how sports nutrition can affect the hormonal background and, therefore, the process of set of muscle mass.

Chapter 2: Influence of the main types of sports nutrition on hormonal background

2.1. Protein: serum, casein, soy, egg

Protein is a fundamental macronutrian necessary for the growth and restoration of muscle tissue. Various types of protein differ in their amino acid structure, the speed of assimilation and the effect on the hormonal background.

• Wastein protein: This type of protein is one of the most popular in sports nutrition due to its high speed of assimilation and rich amino acid composition, especially in terms of leicin, key amino acid, stimulating protein synthesis. Serum protein can have a moderate effect on increasing insulin levels, which contributes to the transport of amino acids to muscle cells and accelerates the recovery process after training. Studies have shown that the consumption of serum protein after training can help increase the level of testosterone and a decrease in the level of cortisol, which creates a favorable hormonal environment for muscle growth.
• Casein: This type of protein is absorbed more slowly than whey, ensuring the gradual release of amino acids within a few hours. Casein is especially useful for consumption before bedtime, as it prevents muscle catabolism during night starvation. Casein has a lesser impact on insulin levels than serum protein. Some studies have shown that casein can help reduce cortisol levels, which can also be useful to prevent the decay of muscle tissue.
• Soy protein: This type of protein is a plant source of protein and contains all the necessary amino acids. However, soy protein contains phytoestrogens that can simulate the effect of estrogen in the body. Some studies have shown that the consumption of soy protein can reduce the level of testosterone in men, while other studies have not revealed significant influence. It is important to note that the effect of soy protein on hormonal background can vary depending on the individual characteristics of the body.
• Egg protein: This type of protein has high biological value and contains all the necessary amino acids. Egg protein is absorbed at an average speed, which makes it a good choice for consumption at any time of the day. Studies have shown that the consumption of egg protein can help increase the level of testosterone and a decrease in the level of cortisol, like serum protein.

2.2. Creatine: monohydrate, ethyl ether, hydrochloride

Creatine is one of the most studied and effective sports additives to increase strength and muscle mass. Creatine increases the level of phosphocratin in muscle cells, which provides a quick source of energy for intense training.

• Creatine Monogidrate: This is the most common and studied form of creatine. Creatine monohydrate effectively increases the level of creatine in the muscles, which leads to an increase in strength, power and muscle mass. Studies have shown that creatine monohydrate can have a slight effect on testosterone levels, but these changes are usually not clinically significant.
• Creatine Ethyl ether (KEE): This form of creatine is considered more bioavailable than creatine monohydrate. However, studies have shown that Key is less effective than creatine monohydrate, and may even break up in the stomach to inactive creatinine. Key does not have a significant effect on the hormonal background.
• Creatine hydrochloride (kg): This form of creatine has increased solubility, which theoretically should improve its assimilation. However, studies show that kg is not more effective than creatine monohydrate. Kg does not have a significant effect on the hormonal background.

2.3. Amino acids: BCAA, EAA, Glutamine

Amino acids are construction blocks of proteins and play an important role in the growth and restoration of muscle tissue.

• BCAA (amino acids with an extensive chain): BCAA includes leucine, isolacin and valin. Leucin plays a key role in stimulating protein synthesis. BCAA can help reduce muscle pain after training and improve recovery. Studies have shown that BCAA can have a slight effect on the level of testosterone and cortisol, but these changes are usually not clinically significant.
• EAA (essential amino acids): EAA includes all amino acids that the body cannot synthesize independently and should receive from food. EAA is necessary for the synthesis of protein and muscle growth. EAA can have a more pronounced effect on the stimulation of protein synthesis than BCAA. Studies have shown that the EAA can help increase the level of testosterone and a decrease in the level of cortisol, which creates a favorable hormonal environment for muscle growth.
• Glutamine: Glutamine is the most common amino acid in the body and plays an important role in the immune function, restoration after training and maintaining intestinal integrity. Glutamine can help reduce cortisol levels and improve recovery after training.

2.4. Testosterone booster: D-asparaginic acid, T T T T T Tures, Classic Extract

Testosterone booster is additives that are claimed to increase testosterone levels in the body.

• D-paraginic acid (D-AA): D-AA is an amino acid that is involved in the production of testosterone in the testicles. Some studies have shown that D-AA can increase testosterone levels in men with low testosterone levels. However, other studies did not reveal the significant effect of D-AA on testosterone levels.
• TRIBULUS TERRSTIS: This plant is traditionally used to increase libido and improve sports results. However, studies have shown that Tertrix tribulus does not have a significant effect on testosterone levels.
• Claim extract: The fencing is a plant that contains compounds called saponins, which can stimulate testosterone production. Some studies have shown that fencing extract can increase testosterone levels and improve libido.

2.5. Pre-working complexes: caffeine, beta-alanine, arginin

Preventive complexes usually contain a mixture of ingredients designed to increase energy, focus and performance during training.

• Caffeine: Caffeine is a stimulant that increases energy levels, improves focus and reduces the feeling of fatigue. Caffeine can increase the level of cortisol, especially with high doses.
• Beta-Alanine: Beta-Alanin is an amino acid that increases the level of carnosine in the muscles, which helps buffer lactic acid and reduce muscle fatigue. Beta-Alanin does not have a significant effect on the hormonal background.
• Arginine: Arginine is an amino acid that is involved in the production of nitrogen oxide (No), which expands blood vessels and improves blood flow. Arginine can have a slight effect on the level of growth hormone.

Chapter 3: Factors affecting the hormonal response to sports nutrition

3.1. Individual features: age, gender, genetics

The hormonal response to sports nutrition can vary significantly depending on individual characteristics.

• Age: With age, the level of testosterone in men is reduced, which can affect the effectiveness of sports nutrition for the recruitment of muscle mass.
• Floor: Men and women have different hormonal profiles, which can affect their reaction to sports nutrition. For example, women have a lower level of testosterone than men, and can be more sensitive to the influence of soy protein on hormonal background.
• Genetics: Genetic factors can affect the level of hormones and sensitivity to them, which can affect the reaction to sports nutrition.

3.2. Intensity and type of training

The intensity and type of training also affect the hormonal response to sports nutrition. High -intensity training, especially strength training, can stimulate the production of testosterone and growth hormone. Sports nutrition consumption after training can strengthen this hormonal response and contribute to muscle growth.

3.3. Diet and general health

Diet and general health can also affect the hormonal response to sports nutrition. Calorie deficiency and lack of necessary nutrients can reduce testosterone levels and prevent muscle growth. Chronic diseases and stress can also affect hormonal background.

3.4. Dosage and time of receiving sports nutrition

The dosage and time of receiving sports nutrition can also affect its effectiveness and influence on the hormonal background. For example, the consumption of serum protein after training can be more effective for stimulating protein synthesis than its consumption at another time of day. Too high doses of sports nutrition can lead to undesirable side effects, including hormonal imbalance.

Chapter 4: Potential risks and side effects of sports nutrition associated with hormonal background

4.1. Impact on testosterone and estrogen levels

Some types of sports nutrition, such as testosterone booster and soy protein, can influence the level of testosterone and estrogen. It is important to understand the potential risks and side effects of these additives.

4.2. Violation of the thyroid gland and adrenal glands

Some types of sports nutrition can affect the work of the thyroid gland and adrenal glands. For example, some pre -rating complexes contain stimulants that can overload the adrenal glands.

4.3. Impact on reproductive function

Some types of sports nutrition can influence the reproductive function in men and women. For example, some testosterone booster can suppress the production of their own testosterone, which can lead to a decrease in libido and a deterioration in sperm quality.

4.4. Hormonal disorders in adolescents

Teenagers are more vulnerable to hormonal disorders caused by sports nutrition. It is important to be careful when using sports nutrition by adolescents and consult a doctor or nutritionist.
