Protein is essential for muscle recovery and growth. Muscle tissue is made up of two protein filaments: myosin and actin. These filaments interact with each other to contract muscles. Constant movement and training cause mechanical stress that damages these protein filaments. As a result, muscles need a daily supply of protein to repair and rebuild themselves. The amount of protein required to build muscle depends on body weight and activity levels. While protein is crucial, it is not the only factor in muscle growth. The type and amount of exercise, calorie intake, and other nutrients like carbohydrates and fats are also important considerations.

What You'll Learn
Resistance training and protein intake
Protein is the only nutrient that directly builds muscle, and it is essential for muscle recovery and growth. The body breaks down protein into amino acids, which are then used to repair and strengthen muscle fibres. This process is called muscle protein synthesis (MPS), and it is stimulated by strength training and protein intake.
To build muscle effectively, it is important to consume enough high-quality protein at the right times. The recommended amount of protein intake varies, but it is generally advised to consume 1.6-2.2 grams of protein per kilogram of body weight. This can be achieved through a varied diet of meats, eggs, beans, dairy, and plant-based sources. However, the timing of protein intake is still a subject of debate, with some sources recommending spacing out protein intake throughout the day, while others suggest that the total amount is more important than the timing.
Resistance training is one of the most effective ways to trigger muscle growth. The amount of muscle gained through weightlifting depends on the frequency and intensity of training sessions. To maximize muscle growth, it is recommended to exercise at least twice a week, using weights at 70-90% of one-repetition maximum. Combining resistance training with protein intake increases muscle protein accretion over time, leading to muscle growth and strength gain.

Muscle protein turnover
The anabolic state can be achieved through resistance training and sufficient protein intake to build new tissue. The body needs to be supplied with enough calories to support muscle-building activity, and the right balance of nutrients, including carbohydrates and fats, is also essential. The timing of protein intake is another factor to consider, as MPS is stimulated by strength training and protein consumption.
The measurement of MPS is typically done using the precursor-product model, which involves the injection or infusion of amino acid tracers and the subsequent measurement of their direct incorporation into muscle tissue. MPS measures, however, do not reflect protein anabolism without concurrent measurement of MPB. Therefore, it is ideal to measure both MPS and MPB simultaneously to determine the net muscle protein balance.

Muscle repair and growth
Exercise plays a crucial role in muscle repair and growth. Resistance or strength training, such as weightlifting, creates microtears in the muscle fibres, which leads to muscle damage. This process is essential because it stimulates the body to repair and rebuild the muscle tissue, making it stronger and bigger over time. The amount of muscle growth depends on the frequency and intensity of training sessions. To maximize results, sports scientists recommend exercising at least twice a week and using weights that are 70-90% of an individual's one-repetition maximum.
Nutrition is another key factor in muscle repair and growth. Protein, specifically, is essential as it is the direct precursor to building muscle. The body breaks down protein into amino acids, which are then transported to the muscles to support repair and growth. However, it's important to note that the body also needs other nutrients like carbohydrates and dietary fats to fuel exercise and support overall muscle development. The amount of protein required varies depending on body weight and activity levels, and recommendations range from 1.2 to 2 grams of protein per kilogram of body weight.
Rest and recovery are vital components of muscle repair and growth. Adequate rest, hydration, and sleep are necessary for the body to repair the microtears in the muscles. Sleep deprivation, for example, can impair muscle recovery by disrupting the body's inflammation response and hormone production. Additionally, incorporating activities like massage and wearing compression garments can help reduce muscle soreness and speed up recovery.
In cases of more severe muscle loss or injury, more intensive interventions may be required to support muscle repair and regeneration. These can include surgical techniques, physical therapy, biomaterials, muscular tissue engineering, and cell therapy.

Protein intake and timing
To build muscle, it is essential to consume proper amounts of high-quality protein at the right times. Muscle protein synthesis (MPS) is stimulated by strength training activity and protein consumption.
The body needs a daily supply of protein to rebuild and stay functional. Mechanical stress from weight training can cause micro-tears in the muscle fibres, which need to be repaired. This is why bodybuilders often supplement their diets with protein powder and bars to ensure their bodies have enough protein to maintain their muscle mass.
The amount of protein required to build muscle depends on body weight and activity levels. The American College of Sports Medicine advises athletes to eat 1.2-1.4 g of protein per kilogram of body weight to maintain muscle mass and recover from training. The International Society of Sports Nutrition recommends up to 2 g of protein per kilogram. However, a meta-analysis published in the British Journal of Sports Medicine suggests that consuming more than 1.6 g of protein per kilogram will not provide any additional benefits.
The timing of protein intake is important for optimising muscle growth. Some studies suggest that consuming protein continuously throughout the day is beneficial for muscle growth. For example, a 2013 study found that participants experienced greater muscle growth when consuming 20 grams of protein four times a day. However, it is worth noting that the protein source used in this study was whey, which is a fast-absorbing protein. When consuming slower-absorbing proteins from a varied diet, the 25-gram limit per serving may not apply. Experts recommend consuming about 1.6-2.2 grams of protein per kilogram of body weight per day.
To maximise muscle growth, it is recommended to exercise at least twice a week and use weights at 70-90% of one-repetition maximum. Consuming a dose of protein after a workout can help make up for any protein deficit during the day. Shifting protein intake towards the morning can also stimulate muscle protein synthesis to a greater extent.

Protein alternatives for non-meat eaters
Protein is essential for muscle recovery and growth. The muscle fibres are composed of protein filaments myosin and actin, which are critical to muscle contraction. The body requires a sufficient amount of protein to build new tissue and repair the microtears in the muscle fibres caused by resistance training.
For those who do not eat meat, there are several alternative sources of protein to aid muscle growth and repair. Here are some protein alternatives for non-meat eaters:
Legumes
Legumes, including beans, peas, lentils, and peanuts, are affordable, nutritious, and delicious sources of protein. They are also high in fibre and a good source of iron. A daily serving of legumes can help lower cholesterol levels.
Whole Grains
Wholegrain breads, rice, and pasta have more protein, fibre, and iron than their white counterparts. A serving of 185g of cooked wholegrain rice (or 75g uncooked) contains 7g of protein. A medium slice of whole grain bread contains 3g of protein.
Dairy
Milk, yoghurt, and cheese are great sources of protein and also provide calcium, which is essential for bone health. Lower-fat dairy options can help reduce saturated fat intake without compromising protein or calcium levels.
Nuts
Nuts provide a good dose of protein and are packed with fibre. They are also a convenient snack option and can be easily added to meals or eaten on their own.
Soy-Based Products
Soybeans are a complete protein, comparable in quality to animal protein. Tofu, for example, contains about 25 grams of protein per 3.5 ounces (100 grams) and is also a good source of selenium, iron, calcium, and phosphorus. Other soy-based products include tempeh and edamame, which offer additional nutritional benefits such as probiotics, vitamins, and minerals.
Seitan
Seitan, also known as wheat meat or wheat gluten, is a popular protein source for vegetarians and vegans. It has a similar look and texture to cooked meat and is a rich source of plant-based protein, containing about 25 grams of protein per 100 grams. However, people with gluten-related disorders should avoid it.
Mycoprotein
Mycoprotein is a non-animal-based protein derived from fungus. It is often used in meat substitutes like veggie burgers, patties, cutlets, and fillets. The nutritional value can vary, but it typically provides a good amount of protein and fibre. However, some people may have concerns about food allergies or the presence of egg whites in certain products.
Spirulina
Spirulina is a type of blue-green algae that is known for its high protein content. It also contains high amounts of magnesium, riboflavin, manganese, potassium, and essential fatty acids. Research suggests that spirulina may have antioxidant, anti-inflammatory, and potential anti-cancer properties.
It is important to note that while these alternatives provide protein, the body's ability to build muscle also depends on other factors such as overall diet, exercise routine, and adequate calorie intake.
