Title: In the light of the energy systems used during prolonged endurance events, critically analyse the nutritional strategies that a marathon runner should adopt before and whilst running a marathon in temperate environmental conditions (16-18oC).

1.0 Introduction:
The term energy system refers to the body’s ability, or power, to do physical work. The energy system requires to do body work that takes several different forms: mechanical, electrical, light, radiant, and heat (Economos, 1993). Energy system is like matter, which can neither be created nor destroyed (Bortz, 1993). It can only be changed into another form; therefore energy is constant cycle in the body and environment (Nelson, 1993).
Potential energy is stored energy which is ready to be used. Kinetics energy is active energy which can be used to do work (Burke, 1991). Energy balance in a physical activity requires a base of sound nutrition to supply the substrate fuels, which along with oxygen (O2) and water (H2O) meet widely varying levels of energy demand for body action (Gollan, 1991).
Fuel sources are the basic energy nutrition in the diet, primarily carbohydrate and some fat (Read, 1991). Their metabolic products-glucose, glycogen, and fatty acids-provide ready fuel sourced for the chemical energy reactions within cells (Murray, 1998). The main energy compound of the body cells is needed during a marathon run is aerobic system (Horswill, 1998). It has rightly a form of energy currency of the cell.
A long-term energy system, when exercising more than 2 minutes is required O2 dependant, or
