SummaryExercise causes numerous physiological changes in the body. Body temperature increases during exercise because heat is generated in proportion to our need to produce energy. Sweat is a by product of the body heat generated and is sent to the surface of the skin to evaporate and serves as a cooling mechanism. Aerobic exercise leads to the regeneration of ATP which causes an increased need for oxygen and an increased production of carbon dioxide. These two gases must be delivered and removed for the muscles to function properly. Oxygen is brought into the lungs of the body via inhalation and transferred from the pulmonary circuit to the heart via hemoglobin. The oxygenated blood passes through the heart and out into the body’s organs. Some hemoglobin red blood cells deliver the oxygenated blood to skeletal muscle being contracted during exercise. The muscle uses the oxygen to regenerate ATP aerobically. This process also produces carbon dioxide as a waste product. The carbon dioxide diffuses into capillary blood and travels back up through the heart and into the pulmonary circuit where it is taken to the lungs and disposed of by exhalation.

- Introduction
- Heart rate will inevitably change over the course of the experiment.
- Method
- Oxygen consumption, carbon dioxide clearance, tidal volume, and heart rate were recorded every two minutes and fifteen seconds throughout the exercise portion of the experiment as well as twice during the resting phase and recovery phase.
