An Intro into Rugby Nutrition
18 Oct 2007
What is rugby nutrition?
Rugby nutrition is providing the body with fuel. The body needs fuel to be able to perform efficiently on the field. However, providing the right type of fuel is important. There’s no point driving a Ferrari if you are going to put second rate gas in it. Same applies to your body, there’s no point training hard and then providing your body with inadequate food.
3 of the main nutrients (fuels) for rugby players are:
Carbohydrate is the main fuel for rugby players. Carbohydrate is the ‘petrol in the car’. It gets stored in your muscles as glycogen and when you start exercising it gets broken down to glucose which provides the muscles with energy.
Protein is of primary importance to the growth and development of your body. Protein provides the structural basis of muscle tissues.
It is recommended that fat in your diet should be minimal. By eating too much fatty food your body you will end up carrying to much useless weight and you will become an inefficient player. Your body doesn’t need to carry more weight than it has to! A player should gain weight through muscle mass not fat. Muscle is functional but fat is not functional at all.
How much of each nutrient should we eat per day?
Carbohydrate = 6-9 x 1 kg/body weight per day
Weight of player
|Grams of Carbohydrate|
|75kg||450g – 675g|
|80kg||480g – 720g|
|85kg||510g – 765g|
|95kg||570g – 855g|
|100kg||600g – 900g|
Weight of player
|Grams of Protein|
|75kg||112.5g – 127.5g|
|80kg||120g – 136g|
|85kg||127.5g – 144.5g|
|90kg||135g – 323g|
|95kg||142.5g – 161.5g|
|100kg||150g – 170g|
Pre Game and Recovery Nutrition
The purpose of the pre-game meal is to maximize glycogen stores, especially in the skeletal muscles, and to provide adequate hydration, while minimizing gastric distress, hunger and digestion during competition.
The four important pre-game factors are:
3. Components of the meal
There is limited ability of the muscle to generate glycogen stores when a low fat/high carbohydrate meal is eaten within six hours of competition. The majority of digestion is completed within 4-6 hours and allows for the stomach to be relatively empty. Blood that was needed for digestion is now diverted to the muscles for exercise.
Too small a meal can leave the athlete with low blood glucose levels during prolonged competition, too large a meal can leave a person feeling lethargic. Larger meals take longer to digest.
Components of the meal
Carbohydrate should be the main component of a meal before games. Carbohydrate is the main source of energy and can be digested quicker than other fuel sources. Protein reduces the risk of hunger. Fats prolong digestion and delay gastric emptying so, should be kept low.
Athletes should consume enough fluids to start the competition in a state of hydration. Fluid consumption should be increased in the 24 hours prior to the competition and then up to 500ml should be consumed 15 minutes before start.
Eating immediately post-exercise will speed up refueling. The athlete should consume 1g of carbohydrate/kg body weight within 30 minutes of the completion of the exercise. It is often unappealing to eat a meal after exercise. Most athletes prefer to have a post-exercise snack and then have a meal a few hours later.
