FITNESS FOODS BEFORE EXERCISE

The success of your exercise programme depends on the fuel you put into your body. This will affect the intensity and duration of each session.

For best performance, carbohydrates such as bread, pasta, rice, oats, fruits and vegetables are the body’s preferred fuel source, followed by fats. The body breaks these carbohydrates down into glucose to be used as fuel for energy. A small amount is stored in your muscles in the form of glycogen, providing a fast supply of energy during high-intensity exercise such as sprinting. Fats are used mainly for long, low-intensity exercise such as walking. If you run faster, you’ll use a higher proportion of glycogen than fat.

To maximise your workout, make sure your muscle glycogen levels are high. Low levels can cause tiredness and may reduce the intensity and duration of the session.
