INTRODUCTION: Energy is an important factor for the human body in everyday life. No matter what the human body is doing, whether it is eating, sleeping or running, it needs energy to perform these activities. “Energy fuels your body’s internal functions, repairs, builds and maintains cells and body tissues, and supports the external activities that enable you to interact with the physical world” (Writer). There are five reasons the body needs energy to survive. The first reason is basal metabolism. Basal metabolism is the smallest amount of energy the body needs to function and stay alive while its at rest (Writer). The next reason energy is important is because of body consumption. This determines the energy that is required between person

One of these conclusions includes the subject’s caloric equivalents for oxygen at different non-protein respiratory quotients. Looking at appendix A, it can be shown whether carbohydrates or fats are being burned during which stage of exercise. To start off with the subject had to find her metabolic resting rate. In this stage the subjects respiratory quotient (R.Q) was 0.92. Examining the chart the carbohydrate percentage is higher than the fat percentage making this stage burn carbohydrates. The next stage the subject performed was low intensity. The respiratory quotient for this exercise was 0.90. Looking at the fat percentage and the carbohydrate percentage, again the carbohydrates were higher for the first R.Q resulting in carbohydrates being burned. In next exercise the R.Q was 0.76 for moderate intensity. This time the fat percentage was higher than the carbohydrate percentage which shows the subject is burning fat in this stage. Lastly, the final exercise was high intensity. The R.Q for this exercise was 0.99. This once again shows that the carbohydrate percentage was higher than the fat percentage resulting in the subject burning carbohydrate. In the third phase, fats are being burned only here because the subject is performing a fast walk which allows the subject to feel comfortable which leads to the subject burning her fat. …show more content…
To determine the energy expenditure resting metabolic rate using indirect calorimetry had to be measured. Also, energy expenditure had to be measured during different levels of exercise using the indirect calorimetry. The last thing to help figure out the energy expenditure is to determine substrate utilization during these different types of exercise. Upon gathering all the information from the subject different exercise levels it can be shown how much oxygen she is taking in and how much carbon dioxide she’s expelling, it can be shown how which areas of exercise burn carbohydrates or fats, it can be shown the results of her heart rate and blood lactate and it can show the subject’s caloric energy expenditure. Energy is an important factor when it comes to the human body. “Energy expenditure is the amount of energy (or calories) that a person needs to carry out a physical function such as breathing, circulating blood, digesting food, or physical movement” (Frey, M). For the human body to survive and for people to do daily activities, humans need energy. Measuring the amount of energy needed for an individual can help them achieve different activities for the day, as well as, allow them to figure out how to lose weight and become healthier. The female subject used in this laboratory helps provide a great example of how to figure out energy expenditure by using and indirect calorimetry and
