Is it better to eat a diet high in starchy carbohydrates or protein when I'm training?
You will need more carbohydrate and protein if you are training regularly each day. Carbohydrates are the fuel that power your exercise regime.
Carbohydrates, including bread, pasta, rice, potatoes and cereals, are the most important fuel for muscles, and an essential energy source for the brain and central nervous system.
Carbohydrates are stored as glycogen in the muscles and liver. These stores are small, so a regular intake of carbohydrate is necessary to keep them topped up. Low glycogen stores may result in poor performance and increase the risk of injury. For some sports however, such as weight making sports where elite athletes may have to weigh in at a certain weight category (such as boxing), or endurance sports (such as long-distance running), there can be physiological benefits of training with low glycogen stores during certain sessions. These sessions must be carefully planned, due to the potential risks.
Most people will be able to get enough protein from a healthy, varied diet. Good sources of protein include meat, fish, eggs and dairy foods.
Athletes need protein in greater amounts and at regular intervals throughout the day for muscle growth and repair. The proportions of carbohydrate and protein required will vary depending on the sport, so it's best to seek advice from a qualified professional on your individual requirements.
