• To gain muscle mass faster, you need to consider several key aspects. First, you should pay attention to nutrition. Your diet should be rich in protein, carbohydrates, and healthy fats. Proteins provide muscle building blocks, carbohydrates provide essential energy, and fats facilitate vitamin absorption and maintain hormonal balance.

  Secondly, it's important to organize your training properly. Strength training should be regular and intense, with an emphasis on basic exercises such as squats, presses, and pull-ups. This will help engage multiple muscle groups and promote growth.

  Also, don't forget about adequate rest. Muscles recover and grow during rest periods, so it's important to allocate time for recovery between workouts and get adequate sleep.

  Finally, don't neglect the opportunity to track your results. Keeping a training and nutrition diary will help you understand what's working and what needs adjustment. By following these recommendations, you can significantly speed up the process of building muscle mass.

• To promote muscle growth, it is necessary to consider several key factors. Firstly, proper nutrition is a crucial component. The body needs a sufficient amount of protein, which serves as the building material for muscles. It is recommended to include protein-rich foods in the diet, such as meat, fish, eggs, legumes, and dairy products.

  Secondly, regular physical activity plays a critical role. Strength training, targeting different muscle groups, promotes their strengthening and growth. It is also important to progress in the intensity of training, increasing the weight of the weights or the number of repetitions.

  Recovery should not be forgotten either. Muscles grow precisely during rest periods, so adequate sleep and recovery days between workouts are of great importance. In addition, hydration is also important; Drinking enough water helps maintain metabolism and improves physical performance.

  Additionally, some athletes may consider using supplements such as creatine or protein powders, but it is recommended to consult a doctor or nutritionist before using them.

  By following these guidelines, you can significantly increase your chances of successfully gaining muscle mass.

• Various workouts that emphasize strength training are effective for increasing muscle mass. The main components that promote muscle growth include:

  1. **Strength Training**: The focus should be on weight-bearing exercises such as presses, squats, rows, and deadlifts. They activate several muscle groups simultaneously and promote their growth.

  2. **Progressive Overload Principle**: Gradually increasing the weight or volume of training is key. This forces the muscles to adapt to the load and, as a result, grow.

  3. **Compound Exercises**: Including multi-joint exercises that work multiple muscle groups in your workout routine can help you achieve better results. Examples include barbell squats, bench presses, and pull-ups.

  4. **Training Frequency**: It is recommended to train at least three times a week to ensure sufficient stimulation for muscle growth and recovery.

  5. **Rest Intervals**: It is also important to consider the rest time between sets, which should be between 60 and 90 seconds to maximize the effect.

  6. **Proper Nutrition**: It is necessary to provide the body with enough protein and calories for muscle recovery and growth. This includes eating protein-rich foods such as meat, fish, eggs, dairy products, and plant-based sources.

  By following these recommendations and combining different training methods, you can effectively gain muscle mass.

• The 1RM, or first period of the menstrual cycle, represents an important stage in a woman's reproductive life. Knowing your 1RM is essential, as it helps you understand your body's characteristics and track changes in your menstrual cycle. This knowledge allows women to more effectively manage their health, predict ovulation days, and plan pregnancy or contraception. In addition, information about your first period can serve as an indicator of your overall health and help identify possible disorders or diseases. Therefore, understanding your 1RM is an important step toward taking a conscious attitude toward your body and overall health.
• To effectively increase muscle mass, you need to pay attention to proper nutrition. The basic principles include the following:

  First, it is important to provide the body with enough calories. To grow muscle, you need to create a caloric surplus, that is, consume more energy than you expend. This can be achieved by increasing portion sizes and choosing high-calorie foods.

  Secondly, the emphasis should be on protein. Protein plays a key role in muscle tissue repair and growth. It is recommended to include protein sources such as meat, fish, eggs, dairy products, legumes, and nuts in your diet.

  Furthermore, carbohydrates are also important, as they are the main source of energy for training. Eating complex carbohydrates, such as whole grains, vegetables, and fruits, will help maintain energy levels.

  Don't forget about fats, which are also important for health and body function. Healthy fats found in fish, avocados, olive oil, and nuts should be part of your diet.

  Regularity of meals is also important. It is recommended to eat 4-6 times a day, which will help maintain energy levels and ensure a constant flow of nutrients to the muscles.

  It is important to remember about hydration. Water is necessary for maintaining normal bodily functions, so you should drink enough fluids throughout the day.

  Therefore, to successfully gain muscle mass, you need to focus on a balanced and varied diet that includes all the necessary macro- and micronutrients.

• Sleep plays a key role in the muscle growth process. During the night, the body restores and renews tissue, which is especially important for muscles after physical activity. When we sleep, important biochemical processes occur, such as the production of growth hormone, which promotes muscle mass increase and improved recovery.

  In addition, sleep affects the levels of hormones responsible for metabolism, such as testosterone and cortisol. A proper sleep schedule helps maintain an optimal balance of these substances, which, in turn, promotes effective muscle building. Lack of sleep can lead to decreased performance, loss of strength, and delayed recovery, which negatively impacts training and overall progress.

  It's also worth noting that memory consolidation occurs during sleep, allowing you to reinforce skills acquired during training. This means that quality sleep not only helps you get stronger physically but also improves exercise technique. Overall, adequate and regular sleep is essential for achieving success in building muscle mass and improving your physical fitness.

How Muscles Grow

Muscle tissue in the human body has a unique ability to adapt—it increases in volume with active use.

• Muscle length increases as a result of stretching exercises, which cause the muscles to stretch between several points. During this stretching process, new sarcomeres—the main elements responsible for contraction—are formed at the ends of the elongated muscle fibers.
• An increase in muscle diameter (or volume) occurs due to the formation of new myofibrils, which are muscle fibers. These new fibers are arranged parallel to the existing ones, which leads to an increase in the diameter of the entire muscle. This process is known as hypertrophy.

The Rate of Muscle Gain: How to Achieve Desired Results?

The hypertrophy process occurs rather gradually, and it usually takes several weeks or even months for its results to become apparent [1]. However, with regular and proper training, the body begins to adapt more quickly, which leads to the acceleration of the formation of new muscle tissue. During this period, the most intensive muscle growth is observed [3], [4].

The speed at which you will be able to see the results of growth is largely determined by initial factors such as your gender, genetic predisposition, and athletic experience.

• Hereditary factors play a key role in determining the predominance of a certain type of muscle fibers. In particular, fast-twitch fibers have a greater tendency to increase their mass.
• Gender plays a significant role in the ability to build muscle mass. Although both men and women respond to strength training similarly, testosterone levels, which are higher in men, promote a more noticeable increase in muscle tissue.
• People with more muscle mass experience more pronounced changes at the start of the training process.

According to experts from the American Council on Exercise (ACE), the following matters:

• How regularly do you exercise?
• What kind of exercise do you do?
• The duration of your workout and the time required to recover after it can vary depending on various factors. Typically, physical activity itself can take from 30 minutes to several hours, depending on your goals, fitness level, and type of workout.

  Recovery time also varies from person to person. It can range from several hours to several days, depending on the intensity of the load, the amount of work performed, and the state of your body. It is important to remember that proper recovery includes not only rest, but also proper nutrition, hydration, and, if necessary, additional recovery methods such as stretching or massage.

• Have you determined the correct weight of the weights you are using?
• What is your diet?

A person who plays sports, follows a diet, and adheres to healthy lifestyle principles is able to increase muscle mass significantly faster compared to someone who relies solely on their genetics and does not put in the necessary effort.

Strength training is a physical exercise aimed at developing muscular strength and endurance. Its main goal is to improve the body's functional capabilities and build muscle.

The benefits of strength training are multifaceted. Firstly, it helps increase muscle mass, which, in turn, helps speed up metabolism. Secondly, regular exercise helps strengthen bone tissue, reducing the risk of osteoporosis. It is also worth noting that strength training has a positive effect on the cardiovascular system, improving blood circulation and increasing energy levels.

However, like any other type of physical activity, strength training can also have its negative aspects. Incorrect exercise technique or excessive loads can lead to injuries, strains, and other damage. Therefore, it is important to approach training wisely and consult a specialist beforehand.

To ensure effective and safe training, it is necessary to follow several rules. Firstly, it is important to warm up properly before training to prepare the muscles and joints for the load. Secondly, you should monitor exercise technique and start with light weights, gradually increasing the load. Finally, do not forget about the regularity of training and recovery, including rest days in your schedule.

Necessary conditions for effective muscle growth

Every day, 1-2% of skeletal muscle is subject to destruction and simultaneously restored. Muscle gain occurs when protein synthesis in muscles exceeds their breakdown. Proper muscle training causes stress, which triggers adaptation processes—the muscles begin to grow. To do this, they use the body's reserves, including proteins, fats, carbohydrates, and other essential substances. However, to achieve growth, it is important not only to constantly load the muscles but also to provide them with time to recover.

The three main pillars of muscle gain are strength training, a balanced diet, and adequate rest.

Effective strength training for muscle gain

"The most effective method for increasing muscle mass is weight training. "That's it," Victoria Szekely, a physical therapist, certified strength and conditioning expert, and running coach, shared in an interview with Forbes magazine. Workouts that involve lifting weights are commonly referred to as strength or resistance training. They involve the use of various weights, machines, or even your own body weight to create tension in muscles beyond their natural limits. According to the National Strength and Conditioning Association (NSCA) in the United States, muscle hypertrophy occurs in several stages. First, the muscles are subjected to tension, after which they begin to overcome resistance. At this stage, microdamage to protein structures occurs, which triggers the body's response. This results in the release of various hormone-like substances known as growth factors, which promote an increase in both length and width of muscle fibers. Mechanical stress on muscles causes damage, which in turn triggers the release of growth factors from the tissue. This initiates the process of muscle hypertrophy. Therefore, muscle growth is not dependent on exercise frequency, but is determined by the level of resistance the muscles must overcome. But how can you determine whether this resistance is being created? In this regard, trainers rely on the concept of "1RM," which stands for "one repetition maximum." This refers to the maximum weight you can lift once with proper technique and without risking your health. 1RM values ​​are commonly provided in exercise manuals for various exercises.

ACE experts recommend using a specific type of training program to increase muscle mass [3]:

Target

Sets

Repetitions

Rest Interval

Weight

Hypertrophy is the process of increasing muscle mass.

3–6

6–12

30–90 seconds

70–80% of 1RM

In order to increase muscle mass, it is necessary to determine the working weight as a percentage of the maximum one-repetition weight (1RM). For example, if your 1RM for a particular exercise is 10 kilograms, then it is advisable to lift between 7.5 and 8 kilograms.

One method for a more precise determination is to use the Epley formula: 1RM = the weight you can lift × (1 + 0.0333 × the number of repetitions). Alternatively, using an online calculator can greatly simplify the process.

Knowing your 1RM allows people of varying physical abilities to use the same training methods to increase muscle mass. If your 1RM increases, the number of repetitions remains the same, but the weight is adjusted according to your current capabilities.

• Determine what specific exercise you plan to perform, be it squats, bench press, or something else. The key is to choose an exercise that you can perform with proper technique.
• Warm up with aerobic exercise and dynamic stretching, devoting 15 to 30 minutes to this process. This will significantly reduce the likelihood of injury, so do not neglect the preparation stage.
• Perform 6 to 10 repetitions of the exercise you have chosen, using a weight approximately equal to half of what you consider your maximum.
• Please take a break for one to two minutes.
• Increase the load to 80% of your maximum result. Determining this value on your own can be difficult, so it is best to seek help from a trainer. Complete three sets.
• Spend at least one minute resting.
• Increase the load by about 10% and perform the exercises with one repetition per set. Take at least 1-2 minutes of rest between sets.

Regardless of your preferred type of training, it's important to incorporate exercises that activate multiple muscle groups simultaneously. This will not only increase your endurance but also make it easier to perform various exercises. Plus, this approach will add variety to your workouts.

What exercises should you add to your workout plan? The American College of Sports Medicine (ACSM) offers the following guidelines: [10]

Diet for effective muscle building

In order to increase muscle mass, you need to ensure that you consume more calories than you burn. But by how much exactly should you increase your intake? At rest, each kilogram of untrained muscle tissue uses 5 to 6 calories per day for protein breakdown and synthesis. For trained muscles, this figure is about 9 calories per kilogram per day. Additionally, a single strength training session can increase total resting energy expenditure by 5-9% for three days afterward.

Research shows that for people looking to increase muscle mass, increasing daily calorie intake by 10-20% is necessary. For example, if your normal intake is around 1500-2000 kcal per day, then when doing strength training you should add approximately 350-500 kcal to this figure.

Calories, proteins, fats and carbohydrates are the main components that make up our nutrition. They are often abbreviated as KBZhU. Understanding these elements and being able to count them correctly is essential for managing your diet and achieving your desired health and fitness goals.

Calories are a unit of measurement of the energy we get from food. Proteins are the building blocks of cells and tissues, playing a key role in muscle repair and growth. Fats, despite their reputation, are essential for the body to absorb vitamins and provide energy reserves. Carbohydrates serve as the body's primary source of energy, especially during physical activity.

To correctly count KBZhU, you need to know how many calories and grams of each of these macronutrients are contained in the foods you eat. Various nutrient tables or specialized apps can be used for this. It's important to consider not only the total number of calories but also the balance between proteins, fats, and carbohydrates to achieve optimal nutrition depending on your goals, whether it's weight loss, gaining weight, or maintaining your current weight.

Thus, correctly calculating your KBZhU will help you better navigate your diet, choose foods that meet your needs, and ultimately lead to improved health and well-being.

A single bout of physical activity activates protein synthesis within 2–4 hours, and this elevated level can persist for up to 24 hours [1]. However, after exercise, protein breakdown also accelerates, especially when there is a shortage of glucose for muscles. Tissue metabolism is organized in such a way that cells are able to produce glucose from proteins if needed. Therefore, it is extremely important to increase the consumption of protein products after training - this helps slow down the breakdown of muscle proteins and promotes the growth of new muscle fibers [12].

To increase muscle mass, you can use protein from the following sources:

• Animal sources include products such as chicken breast, beef, eggs, fish, milk and dairy products;
• Plant sources of protein include legumes, quinoa, nuts, mushrooms, soy and tofu.

How to gain weight correctly and what reasons may motivate this step.

According to the International Society of Sports Nutrition (ISSN), in order to maintain muscle mass, it is necessary to consume at least 0.6–0.9 grams of protein per kilogram of body weight. To achieve an increase in muscle mass, however, significantly more is required – from 1.4 to 2 grams of protein per kilogram.

Meals for athletes are planned with time in mind, and meals are selected in accordance with the strength training schedule. To effectively increase muscle mass, it is necessary not only to correctly calculate the ratio of proteins, fats and carbohydrates, but also to take into account the time of day when they are consumed.

• Healthy fats should be consumed 5-6 hours before training, as they take longer to digest.
• Consuming carbohydrates four hours before training helps increase glycogen stores in the muscles. During strength training, this glycogen breaks down into glucose, which provides the muscles with the necessary energy.
• After training, it is important to include protein in the diet.

The Role of Sleep in Muscle Building

Of course, adults also have the ability to "grow in their sleep" when it comes to muscles. Recovery from physical activity takes time, and it is during the period between workouts that muscle fibers increase. Therefore, it is important to master the art of proper rest, which primarily includes quality sleep. According to Dr. Graham, in order for our cells to enter the regeneration and renewal phase, we need to sleep 7 to 8 hours a day. Lack of sleep slows down the recovery process and increases the likelihood of serious injury.

Sleep promotes rapid muscle growth, since the following processes occur during sleep:

• Growth hormone is synthesized during the third phase of sleep, which is called deep sleep.
• A decrease in the level of cortisol, known as the "long-term stress hormone", leads to the accumulation of fat reserves, but is not without a negative effect on the muscles, since the process of protein breakdown in them is accelerated.
• Testosterone synthesis, which is one of the key factors contributing to muscle mass increase, is supported [1], [17].

In conclusion, it should be emphasized that muscle mass increase is possible at any age, even if you are over ninety. Researchers from Queen's College, part of the University of Cambridge, found that ten weeks of regular strength training can lead to an average gain of 1.4 kilograms of muscle. This effect was not age-dependent, as it was observed in more than 1,600 volunteers, ranging in age from 21 to 80.

How Muscles Grow

Muscle tissue in the human body has a unique ability to adapt - it increases in volume with active use [1], [4].

• Increased muscle length occurs as a result of stretching exercises, which involve stretching the muscle between several points. During this tension, new sarcomeres, which are contractile units, are formed at the ends of the stretched muscle fibers.
• An increase in muscle diameter (volume) occurs due to the formation of new myofibrils, that is, muscle fibers. These new fibers are located parallel to the existing myofibrils, which leads to an overall increase in the muscle diameter. This process is called hypertrophy.

The rate of muscle gain: possible growth rates

The hypertrophy process develops quite slowly, and it usually takes several weeks or even months for its results to become apparent [1]. However, with regular and proper training, the body begins to adapt, which leads to accelerated formation of new muscle tissue. It is during this period that the most intense muscle growth occurs [3], [4].

The speed at which you will notice progress is largely determined by your initial parameters, such as gender, genetic predisposition, and previous athletic experience.

• Hereditary factors play a key role in which muscle fibers will predominate in the body. Fibers with a high contraction speed have a greater potential for increasing their mass.
• Gender is an important element influencing the degree to which muscle mass can be developed. Although both sexes respond equally to resistance exercise, the presence of the male hormone testosterone plays a key role in more noticeable increases in muscle tissue.
• People with more muscle mass tend to show more noticeable results in the initial stages of the training process.

According to experts from the American Council on Exercise (ACE), the following is of great importance:

• How regularly do you exercise?
• What types of physical activity do you prefer?
• The duration of a workout and the time required to recover from it can vary depending on many factors. Typically, fitness classes last from 30 minutes to several hours, depending on the goals and type of activity. Recovery, in turn, can take from several hours to several days, taking into account the intensity of the workout, your level of fitness, and individual characteristics. Proper nutrition, rest, and active recovery play a key role in this process.
• Have you chosen the correct weight for your weights?
• What is your diet?

People who follow a proper training regimen, a balanced diet, and lead an active lifestyle are able to increase muscle mass faster than those who rely on their genetics and do not put in enough effort.

Strength training is a physical exercise aimed at increasing muscle mass, strength, and endurance. It involves working with various weights, such as dumbbells, barbells, or your own body weight. The main goal of such training is to develop muscles and improve the body's functional capabilities.

The benefits of strength training are multifaceted. Regular exercise helps strengthen muscles, which, in turn, increases overall physical activity and improves posture. In addition, strength training can aid in weight loss, as increased muscle mass speeds up metabolism. It also has a positive effect on bone health, reducing the risk of osteoporosis, and helps improve cardiovascular function.

However, like any other physical activity, strength training has its potential risks. Incorrect exercise technique or excessive strain can lead to injuries that require a long recovery. In addition, insufficient recovery time between workouts can lead to fatigue and a decrease in overall performance.

To maximize the benefits of training and minimize risks, it is important to follow certain rules. Beginners are advised to contact trainers for advice on exercise technique and the development of an individual training plan. It is also important to consider your level of fitness and not strive for immediate results, starting with light weights and gradually increasing them. Don't forget about the importance of warming up before and cooling down after workouts to prevent injuries and improve muscle recovery.

Necessary conditions for effective muscle growth

Every day, 1-2% of skeletal muscle is subject to breakdown and regeneration. An increase in muscle mass is observed when the process of muscle protein synthesis exceeds its breakdown. When you load your muscles correctly, they are subjected to stress, which triggers the processes of adaptation and growth. To do this, muscles use the body's reserves, including proteins, fats, carbohydrates, and other important nutrients. However, for successful growth, it is necessary not only to train regularly, but also to provide the muscles with sufficient time to recover.

The three fundamental elements of building muscle mass are strength training, a balanced diet, and quality rest.

Effective strength training for increasing muscle mass

"The most effective method for increasing muscle mass is weight training. This is undeniable," Victoria Szekely, a physical therapist, certified strength and conditioning expert, and running coach, told Forbes magazine.

Training that focuses on lifting weights is known as strength training or resistance training. These exercises use weights, machines, or even your own body weight to create tension in your muscles beyond their normal limits.

According to the National Strength and Conditioning Association (NSCA) in the United States, the process of muscle hypertrophy can be described as follows: initially, the muscles are subjected to a load, after which they overcome resistance. At this critical moment, microtrauma to the protein structures occurs, which triggers a response in the body. This results in the release of various hormone-like substances known as growth factors, which promote an increase in muscle fibers in both length and width.

Mechanical stress leads to damage to muscle tissue, which, in turn, causes the release of growth factors from the tissue. This promotes muscle hypertrophy.

Therefore, muscle growth is not determined solely by the frequency of exercise, but depends on the level of resistance that the muscles must overcome. But how can you determine whether this resistance is being created? In this situation, trainers resort to the term "1RM," which stands for "one-repetition maximum." This refers to the greatest amount of weight you can lift in one set while maintaining proper technique and safety. The 1RM parameter is usually listed in manuals for various exercises.

ACE experts recommend a specific approach to training to increase muscle mass [3]:

Target

Sets

Repetitions

Rest interval

Weight

Hypertrophy, or muscle gain, is the process by which muscles become larger and stronger. This phenomenon is usually associated with regular physical activity, especially strength training, which stimulates muscle fiber growth. With this exposure, the body adapts by increasing muscle size, which in turn promotes improved fitness and overall function.

3–6

6–12

30–90 seconds

70–80% of 1RM

To effectively increase muscle mass, it is necessary to determine the weight to lift based on a percentage of your one-repetition maximum (1RM). For example, if your 1RM for a particular exercise is 10 kilograms, then it is recommended to use a weight in the range of 7.5 or 8 kilograms.

For more accurate results, you can use, for example, Epley's formula: 1RM is equal to the weight you can lift multiplied by (1 + 0.0333 multiplied by the number of repetitions). An alternative and easier way is to use an online calculator.

Knowing your 1RM allows people with different fitness levels to use the same training guidelines to increase muscle mass. If your 1RM increases, the number of repetitions remains the same, but the weight is selected in accordance with your current physical capabilities.

• Decide on the exercise you plan to perform, be it squats, bench press, or something else. The key is to choose an exercise that you can perform with proper technique.
• Spend 15-30 minutes on an aerobic warm-up and dynamic stretching. This will significantly reduce the risk of injury, so do not neglect this important part of preparation.
• It is recommended to perform 6 to 10 repetitions of the exercise, using a weight that is approximately half of your expected maximum.
• Pause for one to two minutes.
• Lift the weight to 80% of your maximum result. Determining this figure on your own can be difficult, so it's best to work with a trainer. Perform three repetitions.
• Take at least a minute to rest.
• Increase the load by about 10% and perform one repetition at a time, taking at least 1-2 minutes of rest between sets.

Regardless of what type of training you prefer, it's important to include exercises that activate multiple muscle groups in your program. This will increase your endurance and make it easier to perform various physical activities. This approach will also add variety to your workouts.

What exercises should you add to your workout schedule? The American College of Sports Medicine (ACSM) offers a set of guidelines that include the following activities [10]:

Diet for effective muscle mass gain

In order to increase muscle mass, you need to consume more calories than you burn. But by how much exactly? At rest, a kilogram of undeveloped muscle uses approximately 5 to 6 calories per day for the processes of breakdown and synthesis of protein. While a kilogram of developed muscle requires about 9 calories per day. In addition, one strength training session can increase the level of energy expenditure at rest by 5-9% for three days after the session.

Research shows that people looking to increase muscle mass need to consume 10-20% more calories. This means that if your normal daily calorie intake is around 1,500–2,000, you should increase that amount by 350–500 calories when doing strength training.

Kcalories, proteins, fats, and carbohydrates (KPFC) is an abbreviation for calories, proteins, fats, and carbohydrates (CPFC). These components are essential nutrients that play a key role in maintaining the body's health and energy. Correctly calculating your calorie intake allows you to manage your diet and achieve various goals, whether it's weight loss, muscle gain, or weight maintenance.

To effectively calculate your calorie intake, it's important to start by determining your daily calorie needs. This can be done using various formulas, such as the Harris-Benedict formula or the Mifflin-San Jora formula. Once you've determined this figure, you should pay attention to the ratio of proteins, fats, and carbohydrates in your menu. It is generally recommended that proteins make up 10-35% of your total calorie intake, fats 20-35%, and carbohydrates 45-65%.

Next, to track your calorie intake, you can use specialized apps or tables to help you keep track of your food intake. It's important to consider not only the calorie count but also the quality of foods, as some macronutrient sources can be more nutritious and beneficial than others. Therefore, a smart approach to calculating your calorie intake can significantly improve your well-being and help you achieve your goals. A single workout activates protein synthesis for 2-4 hours, and this elevated level can persist for 24 hours. However, after exercise, protein breakdown also accelerates, especially when muscle tissue is deficient in glucose. Cellular metabolic mechanisms are designed to convert protein into glucose when needed. Therefore, after training, it is extremely important to increase the consumption of protein products - this helps slow down the breakdown of muscle proteins and promotes faster formation of new muscle fibers.

To increase muscle mass, you can use the protein contained in the following products:

• Animal protein sources include chicken breast, beef, eggs, fish, as well as milk and milk-based products.
• Plant protein sources include legumes, quinoa, nuts, mushrooms, soy, and tofu.

Weight Gain and Why It May Be Necessary.

According to the International Society of Sports Nutrition (ISSN), to maintain muscle mass, it is necessary to consume at least 0.6–0.9 grams of protein per kilogram of body weight. At the same time, to promote muscle growth, it is recommended to increase protein intake to a level of 1.4 to 2 grams per kilogram of body weight [13].

Athletes are provided with a detailed nutrition plan that takes into account meal times, and the meals themselves are adjusted to the strength training schedule. To effectively build muscle mass, it is important not only to correctly calculate the amount of proteins, fats, and carbohydrates, but also to distribute them over the time of day.

• Healthy fats should be consumed 5-6 hours before exercise, as they take longer to digest.
• Consuming carbohydrates four hours before training helps increase muscle glycogen levels. During strength training, this glycogen is broken down into glucose, which serves as an energy source for muscle fibers.
• After completing physical activity, it is important to include protein in your diet.

The Role of Sleep in Muscle Building

Of course, adults also experience "sleep growth" when it comes to muscle development. They need time to recover from physical activity, and it is during the period between workouts that muscle fiber growth occurs. Therefore, it is crucial to master proper rest skills, especially in terms of sleep. According to Dr. Graham, in order for our cells to enter the recovery and renewal phase, we need to sleep 7 to 8 hours a day. Lack of sleep slows down recovery processes and increases the likelihood of serious injuries. Sleep promotes faster muscle growth because during sleep: Growth hormone begins to be synthesized during the third stage of sleep, which is commonly known as deep sleep. Cortisol levels, known as the "chronic stress hormone," gradually decrease, leading to an increase in fat stores in the body. At the same time, this hormone does not spare muscle tissue, promoting accelerated protein breakdown in the muscles.

In conclusion, it is worth emphasizing that an increase in muscle mass is possible at any age, even if you are over 90 years old. Researchers from Queen's College, part of the University of Cambridge, have found that ten weeks of regular strength training can achieve an average gain of 1.4 kilograms of muscle. Interestingly, this effect was observed regardless of the age of the participants, since more than 1,600 volunteers who participated in the study ranged in age from 21 to 80 years.
