Describe and explain the importance of energy balance in relation to a sports performer

Extracts from this document...


Describe and explain the importance of energy balance in relation to a sports performer - P4, M2, and D1 Energy is expended in a number of different ways such as resting metabolic rate, thermic effect of activity, thermic effect of feeding and adaptive thermogenisis. Your energy balance is the balance of calories consumed through eating and drinking compared to calories burned through physical activity. What you eat and drink is energy in. What you burn through physical activity is energy out. You burn a certain number of calories just by breathing air and digesting food. You also burn a certain number of calories through your daily routine. An important part of maintaining energy balance is the amount of physical activity that you do. ...read more.


The amount of energy foods can produce is measured in units called calories. A food calorie, or kilocalorie, is the amount of heat required to raise the temperature of 1 kilogram of water 1 degree Celsius. The body changes the calories in food into energy, which is necessary for every act from blinking an eye to running a race. Energy is also used for the growing process, for rebuilding damaged cells, and for regulating body systems. Food energy is measured in kilojoules. The common term for this used to be Calorie, but kilojoules is the term. This unit of measurement allows us to look at how much energy a food contains and how much energy is burned up during exercise. One Calorie has the same energy value as 4.186 kilojoules. ...read more.


Age - BMR reduces with age. Energy Sources To find the amount of calories in your food, you need to find the number of CHO Kilocalories Per Gram CHO 4 Protein 4 Fat 9 Thermic affect of activity Anaerobic activity can increase metabolism for hours after exercise has finished. Depending on the intensity of the exercise it can be between 3 to 14 hours after exercise has finished. Thermic affect of feeding Thermic affect of feeding is the increase in energy expenditure above resting metabolic rate due to the cost of processing food for storage and use. It is one of the components of metabolism along with the resting metabolic rate, and the exercise component. Adaptive thermogenisis (AT) Adaptive thermogenesis represents the way the body responds to stress whether it is emotional or environmental for example, changes in temperature. Typically, stressful situations results in an increase in calories burned. ?? ?? ?? ?? Unit 10 - Nutrition Abbie O'Brien ...read more.
