- Proteins – Tissue growth – known as the body’s building blocks. Athletes frequently use protein supplements in their diet and will consume protein immediately after training, sometimes as a ‘shake’.
- Carbohydrates – Source of energy. Divided into: simple carbohydrates – sugars and complex carbohydrates – starches. Athletes need to consume larger quantities of carbohydrate to fuel their training and performance. Prior to an endurance event such as a triathlon, athletes might ‘carbo-load’ to ensure they have enough to finish the race.
- Fats – Source of energy. Four types: monounsaturated, polyunsaturated (omega 3 and 6), saturated and trans fats. Fats are stored under the skin and are essential for health. Too much fat can limit an athlete’s performance due to increased weight.
- Minerals – Essential for many processes, eg bone growth/strength, nervous system, red blood cells, immune system. Need small amounts only.
- Vitamins – Essential for many processes, eg bone growth, metabolic rate, immune system, vision, nervous system. Need small amounts only.
Water and fluids – The body needs to be hydrated to stay healthy. Women should drink around 1.6litres (approximately 8 glasses) of fluid and men should drink around 2litres (approximately 10 glasses) of fluid per day. This varies according to the temperature and how rigorous the exercise. All drinks count but water is the healthiest. Fruit juices are fine in moderation but do contain high levels of sugar.
