Nutrition and exercise
The link between good health and good nutrition is well established. Interest in nutrition and its impact on sporting performance is now a science in itself.
Whether you are a competing athlete, a weekend sports player or a dedicated daily exerciser, the foundation to improved performance is a nutritionally adequate diet.
Daily training diet requirements
The basic training diet should be sufficient to:
- provide enough energy and nutrients to meet the demands of training and exercise
- enhance adaptation and recovery between training sessions
- include a wide variety of foods like wholegrain breads and cereals, vegetables (particularly leafy green varieties), fruit, lean meat and low-fat dairy products to enhance long term nutrition habits and behaviours
- enable the athlete to achieve optimal body weight and body fat levels for performance
- provide adequate fluids to ensure maximum hydration before, during and after exercise
- promote the short and long-term health of athletes.
The athlete’s diet
An athlete’s diet should be similar to that recommended for the general public, with energy intake divided into:
- 45 to 65% from carbohydrates
- 15 to 25% from protein
- 20 to 35% from fat.
Athletes who exercise strenuously for more than 60 to 90 minutes every day may need to increase the amount of energy they consume, particularly from carbohydrate sources.
Guidelines for carbohydrate and protein based on grams intake per kilogram (g/kg) of body weight are also available.
The current recommendations for fat intake are for most athletes to follow similar recommendations to those given for the general community, with the preference for fats coming from olive oils, avocado, nuts and seeds.
Athletes should also aim to minimise intake of high-fat foods such as biscuits, cakes, pastries, chips and fried foods.
