What Nutritional Strategies Can Help Increase Lean Mass in Rugby Forwards?

April 15, 2024

If you’re involved in the world of rugby, you’ll know that a player’s physical fitness is just as important as their skill with the ball. In fact, the physical demands of the game require players to continuously work on their body composition and muscle mass. Focusing more on rugby forwards, they need a higher level of lean mass compared to rugby backs due to their role in the game. To achieve this, nutrition plays a crucial role. Therefore, this article will delve into the nutritional strategies that can help rugby forwards increase lean mass.

Understanding the Role of Nutrition in Muscle Development

Before diving into specific nutritional strategies, it’s key to understand how nutrition contributes to muscle development. The food that players intake acts as fuel for the body. It provides the energy required for intense training sessions and helps promote recovery post-training.

A player’s diet can greatly influence their muscle mass and overall performance. A balanced diet high in protein, carbohydrates, and healthy fats can support muscle growth and recovery. More specifically, the intake of protein supports muscle repair and growth, carbohydrates provide the energy needed for workouts, and fats aid in hormone production and overall body health.

Protein Intake: The Building Blocks of Muscle

Protein is often referred to as the building block of muscles. It is essential in the recovery and growth of muscle tissue which undergo wear and tear during rigorous training sessions. A high protein intake aids in muscle recovery and can increase muscle mass over time.

For rugby players, particularly forwards, the daily intake of protein should be around 1.5 to 2.0g per kilogram of body weight. This means that a 100kg rugby forward would need between 150 to 200g of protein per day. This protein intake can be achieved through a combination of whole foods such as lean meats, dairy, eggs, and plant-based proteins, as well as supplementation if necessary.

Carbohydrate Intake: Fuel for Energy

Carbohydrates are the body’s main source of energy. They are essential for high-intensity sports such as rugby where athletes need energy to perform explosive movements and endure lengthy matches.

Rugby forwards should aim for a daily carbohydrate intake of around 5 to 7g per kilogram of body weight. This means if a player weighs 100kg, they should aim for 500 to 700g of carbohydrates per day. This can be achieved through foods like whole grains, fruits, vegetables, and legumes.

It’s crucial to note that the timing of carbohydrate intake can also impact performance and recovery. Consuming carbohydrates before a training session can provide the energy needed to perform at a high level. Post-training, a carbohydrate-rich meal can replenish energy stores in the muscles, promoting recovery.

The Importance of Hydration

Hydration, although not often considered a nutrient, is vital in maintaining high performance and promoting recovery in rugby players. Staying hydrated helps in maintaining blood volume, regulating body temperature, and facilitating muscle contractions – all of which are crucial during training and game day.

While water is the most obvious choice for hydration, sports drinks that contain electrolytes can also be beneficial, especially during long training sessions or matches. These drinks not only replenish fluids lost through sweat but also provide a source of energy in the form of simple carbohydrates.

Relative Energy Deficiency in Sport (RED-S)

The concept of Relative Energy Deficiency in Sport (RED-S) is important to highlight when discussing nutritional strategies for rugby forwards. RED-S refers to the imbalance between the player’s energy intake and the energy expended during training and matches.

If a player is in energy deficiency, it can negatively impact their performance, recovery, and overall health. Therefore, it’s crucial for players to monitor their energy intake and ensure they are consuming enough calories to match their high energy expenditure.

By following the strategies outlined above, rugby forwards can effectively increase their lean mass, enhancing their performance on the field in the process. Remember, the key is individualising the approach and adapting these strategies based on each player’s body composition, training schedule, and personal goals.

Dietary Intakes and Micronutrient Considerations

Dietary intakes of rugby players, especially forwards, must be carefully considered to support lean mass increase. Besides macronutrients, micronutrients also play a significant role in muscle growth and recovery. Vitamins such as B6, B12, and C facilitate protein metabolism and collagen synthesis, both important for muscle recovery and growth. Minerals like calcium, magnesium, and zinc aid in muscle contraction and energy metabolism, reinforcing the necessity of a diversified, nutrient-rich diet.

A study published in the Journal of Sports Sciences showed that dietary intakes of professional players are often insufficient in micronutrients, highlighting the need for dietary planning or supplementation (Crossref Google Scholar).

The timing and composition of pre-game meals can also influence performance. A study on rugby union players revealed that a pre-game meal rich in low glycemic index carbohydrates and moderate in protein improved their performance (PubMed Crossref). As such, a well-timed, balanced meal before a game or intense training can provide the sustained energy required while supporting muscle maintenance and growth.

However, it’s crucial not to fall into dietary redundancy to achieve high protein and carbohydrate intake. A varied diet ensures a range of micronutrients necessary for overall health and optimal performance. This can be achieved by incorporating a diverse array of whole foods, including lean meats, dairy, fruits, vegetables, whole grains, and healthy fats into daily meal plans.

Adapting Nutritional Intakes to Training Load

Training load can significantly affect the energy and macronutrient intakes of rugby players. A study on professional rugby players noted that energy intakes observed were far less than the energy expended during high-intensity training periods (DOI PubMed).

This underlines the importance of adapting the diet according to the training load. During periods of intense training, energy and carbohydrate requirements may increase to support performance and recovery. Conversely, during less active periods, a lower intake may be sufficient.

Adapting the diet based on training schedule and intensity is essential to avoid the risks associated with Relative Energy Deficiency in Sport (RED-S). Regular monitoring of body composition, performance, and dietary intake can help in making personalized dietary adjustments to support lean mass increase.

Tailoring these strategies to each player’s needs, schedules, and goals can help optimize their diet for lean mass increase. It can also help prevent energy deficiencies that could compromise performance and recovery.


Rugby forwards, due to their role in the game, require a higher level of lean mass. Achieving this involves not only rigorous physical training but also strategic nutritional planning. The key lies in creating a balanced diet rich in protein and carbohydrates, diversifying food sources for optimal micronutrient intake, ensuring adequate hydration, and tailoring dietary intakes to training loads.

A well-planned diet supports energy requirements for high-intensity training sessions, aids muscle recovery, and promotes lean mass increase. It also helps address the issue of Relative Energy Deficiency in Sport (RED-S), ensuring the players’ overall health and performance is not compromised.

Players should remember that individual needs vary, and therefore, dietary strategies should be adapted accordingly. Regular monitoring of body composition and performance, combined with nutritional education, can help each player understand their unique nutritional needs and make informed dietary choices.

Like the game of rugby, achieving lean mass increase is a team effort, requiring the collaboration between the player, dietitian, and coaching staff. Together, they can devise a nutritional strategy that supports the player’s health, performance, and lean mass increase.
