This extra ventilation provides an element of safety that can be called on if the situation demands it (eg, at high altitudes, under hot conditions, abnormality in the respiratory system). He inhales more amount of air during exercise. The greater amount of blood in circulation causes an increase in the amount of blood in the left ventricle when the end-diastolic phase is reached. VO2 is the consumption of oxygen and can be explained by the Fick equation. The process of exercise (eg long-distance running or powerlifting) places a burden of stress on muscle fibers and bones which causes micro-tears and trauma. After an introductory chapter on early ideas about the physiology of exercise and the training of athletes, there are eleven in-depth accounts of the development of scientific thinking about the responses of key physiological systems to the conditions of acute and chronic exercise, as well as their coupling with integrative responses.
