Cardiovascular System in Exercise

By Arthur C. Guyton, M.D.† and John E. Hall, Ph.D. on April 16th 2008

Muscle Blood Flow. A key requirement of cardiovascular function in exercise is to deliver the required oxygen and other nutrients to the exercising muscles. For this purpose, the muscle blood flow increases drastically during exercise. A recording of muscle blood flow in the calf of a person for a period of […]

Although one’s respiratory ability is of relatively little concern in the performance of sprint types of athletics, it is critical for maximal performance in endurance athletics. Normal oxygen consumption for a young man at rest is about 250 ml/min. However, under maximal conditions, this can be increased to […]
