Introduction

Sport nutrition P3, P4, M1 Energy measurements Energy from food can be measured in calories, joules, kilocalories and kilojoules. Calories measure energy, especially heat energy. One calorie is the energy required to raise the temperature of one gram of water by one degree Celsius and a kilocalorie is equal to 1,000 calories. A joule is most commonly used to measure energy, one joule moves a mass of 1g at 1 metre per second and a kilojoule is equal to 1,000 joules. Sources Fats, carbohydrate and fat are the main energy fuel used by your body. When they are digested the body uses the three energy sources and the body breaks it down into their basic unit's, carbohydrates into sugars, proteins into amino acids, and fats into fatty acids. The body uses these basic units for growth and activity's. Complex carbohydrate consists of large molecules of simple carbohydrates, so they must be broken down into simple carbohydrates before they can be absorbed so this tends to be quicker than fat and proteins. ...read more.

For example many women thinks it is fashionable to be skinny so this will have an affect on there body composition making them ectomorph. Lean body mass and body fat is how you work out your body composition. Lean body mass includes the bones, muscle, water and organ tissue. Whereas body fats includes your essential and non essential fat stores. Athletes are normally concerned about there weight, generally for performance and health reasons. It is possible to alter your body composition by exercising and a correct diet. There are three methods of assessing your body fat. Skinfold callipers, bioelectrical impedance and hydrodensitometry. Skinfold calliper uses callipers to measure skinfold thickness at several areas of your body. You will need a partner who pinches your skin at different areas and measures them with callipers. The measurements are used to calculate percentage of body fat. Bioelectrical impedance is another good way to measure fat percentage they work by measuring the resistance of body tissues to the flow of a small electrical signal. ...read more.

Conclusion

A low amount of fat will make the swimmer move through the water better. Energy intake and expenditure in football An ideal football player requires 55 to 60 percent of their daily caloric intake to come from carbohydrates, 15 percent from protein, and 30 percent from fat. This is because football is a stop and go sport with short bursts of intense effort followed by rest. Therefore the primary fuel for football is carbohydrate and if the body burns all the carbohydrate storage the body will use fat as an energy source. Footballers tend to be in-between mesomorph and ectomorph making them quick and strong. Energy intake and expenditure in cycling Carbohydrates are the primary source of energy for all cyclists. Fats, an alternative energy source, are more important in slower endurance events. Protein, the third component, is used to maintain and repair cells and tissue, but can also be a backup source of energy. A cyclist will require 70-75 percent of carbohydrates, 15-20% percent from fat and 35% fat. Because cycling is an aerobic sport the body will use up your glycogen storage fast and then your body will use fat as the secondary energy source. ...read more.
