Good eating habits will increase the amount of energy stored in your body, and therefore allow you to perform at the highest level possible. To ensure that you are getting all the nutrients that you need it is important to eat a variety of foods from the four main food groups including cereals,proteins,fruit and vegies and dairy foods. Commercial snack foods and take away foods are often very high in fat and do nothing for energy levels. There are many healthy and delicious alternatives to chips and lollies. Remember also to drink plenty of fluids, athletes need to replace fluids that are lost through perspiration.
Dehydration can cause cramps and other problems so keep that water bottle near and use it.
However, it is important to be able to concentrate on what you are about to do. Practising some simple relaxation techniques can be helpful. Try to turn off from everything that is going on around you. Then make a conscious effort to relax the muscles in your face,neck and shoulders. Focus your mind on what you are about to do and visualise yourself performing successfully.
