Task 2 – Describe (P3) or explain (M1) the concept of energy intake and expenditure in sports performance.
The concept of energy intake and expenditure refers to the amount of calories per day that an individual consumes, and is the chemical energy in foods which can be metabolized to produce energy available to the body. As stated before energy is obtained from the foods we eat and is used to support an individual’s Basal Metabolic Rate, energy is measured in calories or joules as both units are very small they are multiplied by 1,000 and referred to as kilocalories. Different foods provide us with different amounts of energy, and the potential fuel sources available to exercising muscles are fats – 1 gram fat =9.0kcal = 23kJ,

The energy cost of football is estimated as being 16.4kcal per minute amounting to 1480 kcal for a 90 minute match. This therefore highlights that the individual needs post-match fluid and food intake in order to replace lost energy.

Task 3 –Describe (P4), explain (M2) or analyse (D1) the importance of energy balance and their effect on sports performance.
Energy is expended in a number of different ways such as the stated above; resting metabolic rate, thermic effect of activity, thermic effect of feeding and adaptive thermogenesis. An individual’s energy balance is the balance of calories consumed through eating and drinking compared to calories burned through physical activity, what an individual drinks and eat is energy in. what an individual burns though physical activity is energy out. Body weight is maintained and stable in the state of energy balance, the chemical bonds of carbohydrates, proteins and fats in food contain chemical energy which is then transformed in the human body in multiple metabolic processes to cellular energy, heat or stored energy. An individual’s burns a certain number of calories just by breathing air and digested food. They also burn a certain number of calories through their daily routine, an important part of maintaining energy balance is the amount of physical activity an
