In this unit I will talk about balancing energy- intake and expenditure
P3- describes energy intake and energy expenditure in sports performance.
P4- describe energy balance and its importance I relation to sports performance.
We need energy to live our everyday lives.
We gain our energy from foods to support minimum calories each day. This is our (BMR)
Energy is measured joules/calories, these are times by 1000 and
Energy is measured in calories or joules. As both these units are small they are multiplied by 1000 and mentioned to as minor units of heat or kilojoules.

There are four main components to energy production which are:
Resting metabolic rate is a quantity of food or energy is essential to uphold basic body functions such as breathing, heartbeat and care of the body heat while you are at rest. (RMR)
Dietary thermogenesis talks about the energy expended above the RMR for the procedures of digestion, concentration, transport and loading of
