Energy Expenditure and Lab Report Guide - Essay Example

Results While at rest, the ten minute resting oxygen consumption of our was 3.08 VO2 L/m. The respiratory exchangeratio (RER) at rest averaged to 0.7759. The average RER was calculated by taking the average of carbon dioxide production and dividing it by the average oxygen consumption (VO2).When the RER was 0.7759, it was equivalent to 4.776 kilocalories per liquid oxygen. The total resting energy expenditure is calculated by taking 3.08 oxygen consumption multiplied by 4.776 caloric equivalents to a total of 14.

71 kilocalories.To calculate the total resting energy expenditure derived from carbohydrate and fat you take the RER and find the percentage kilocalorie for each one. In this case, the kilocalorie percentage was 26.3 percent from carbohydrate, and 73.7 percent from fat. The total energy expenditure from carbohydrate equaled 14.71 kilocalories multiplied by the 26.3 percent of the total kilocalories from carbohydrate, in the end equaling 3.87 kilocalories from cholesterol alone. The total energy expenditure from fat equaled 14.

71 kilocalories multiplied by the 26.3 percent kilocalories solely from fat; in the end 10.84 kilocalories were from fat.The 10-min oxygen consumption, while exercising for our subject, was equal to 25.39 VO2 L/m. The average RER during our subjects exercise was .8952. The formula that was needed to calculate respiratory exercise ratio during exercise was the average Carbon dioxide production (VCO2) during exercise divided by the average oxygen consumption (VO2). When the RER sums up to .8952 the caloric equivalent to this was 4.

924 kilocalories per liquid oxygen. Gross energy expenditure during exercise is calculated by taking 25.39-oxygen consumption multiplied by 4.924 caloric equivalents equaling a total of 125.02 kilocalories. The net energy expenditure of our subject that was 125.02 equals Gross energy expenditure plus the resting energy expenditure equals 139.73. To calculate the total resting energy expenditure derived from carbohydrate and fat you take the RER and find the percentage kilocalorie for both of them.

The percentage kilocalorie that derived from carbohydrate was 67.5. The percentage kilocalorie that came from fat was 32.5. The energy expenditure from carbohydrates equaled to 139.73 kilocalories multiplied by 67.5 percent equaling a total of 74.07 kilocalories deriving from carbohydrates. The energy expenditure from fat equals 139.73 kilocalories multiplied by 32.5 percent equaling a total of 45.41 kilocalories from fat.DiscussionThis sort of testing can be applied to athletes to further study how much oxygen consumption and how much energy they expend since we all work differently.

This testing is great for individual purpose as well as academic to further study how much the body utilizes oxygen as well as energy and to determine the status of aerobic endurance in a set individual. We run these sorts of test to get increased knowledge of the human body plus its many capabilities so that you can know the basic energy expenditure that comes from fat or carbohydrate at both rest and while exercising. We wait five minutes so the body can reach a set plateau since we had a treadmill at a constant speed.

After the 5-minute mark, the body is at a constant rate unlike the first 5 min where the body is trying to find that constant range of oxygen intake and energy expenditure. It is important to wait these critical five minutes because you want to get data that is as accurate as possible that way your averages are within range of each other since as training commences there is use of more anaerobic pathways. Our results indicate that our subject while at rest burned any fat hardly compared to the carbohydrate.

While exercising, the fat percentage increased by nearly double at a fairly moderate jog. At rest, the average VO2 was 3.08 and during exercise 25.39. By simply comparing both of these numbers, you can see a very steep increase concluding that while exercising the body requires a much larger amount of oxygen consumption leading to believe that the carbon dioxide production will be just as high. The average carbon dioxide consumption at rest was .7759 and while during exercise 0.8952. In conclusion, the body seems to use more carbohydrate while at rest and during exercise but when put to exercise starts using more lipids as an energy source.

The body also consumes much more VO2 during exercise that indicates higher levels of VCO2 exiting out of the body
