Metabolism Lab Report essay

For both subjects, the amount f air inspired increased with the intensity of exercise, along with the total volume of oxygen consumed. This directly correlates with METS, which increase with more vigorous exercise. In addition to this the volume of carbon dioxide produced, also increases with exercise. These correlations allow us to make predictions on R. We expect the weight bearing activity to produce values higher than rest and the non-weight bearing activity because you intake the most oxygen. At rest, you would expect to see a little over 1 MET, since these subjects were In a resting metabolic state, not a basal metabolic state.

This is equivalent to slightly over 3. 5 ml 02/keg/min. At rest and in a post-absorptive, you would expect to see R near . 7 since the body would be burning fats. As the intensity of exercise is increased, you expect for R to increase towards 1. 0 because it is easier for the body to obtain TAP quickly from burning glucose than from burning fat. B. There would definitely be a different caloric expenditure between a large person and a small person based on whether or not the activity is weight bearing or non-weight bearing. On a treadmill, you should expect to see different caloric expenditures for people of different sizes.

Since this is a weight bearing exercise, a person that is heavier will burn more calories on a treadmill at a given speed and incline than a smaller person. This difference is not really seen in non-weight exercise. In contrast, using the cycle regretted, a non-weight bearing exercise, you would not expect to see as much of a difference in calories burned based on size. C. The advantage of expressing oxygen consumption relative to body weight (VEERED in ml/keg/min) versus absolute oxygen consumption (VISAS in L/min) is that it takes into account other factors including body weight rather than just oxygen consumption.
