Q

List 3 physiological adaptations that occur to improve exercise performance and state how or why improvements occurs.

A
  1. Increased maximal blood flow - Performing aerobic exercise forces large volumes of blood which increases stroke volume.
  2. Increased oxygen delivery and carbon dioxide removal - The cardiorespiratory system saturates blood coming from the lungs with oxygen efficiently. The high pulmonary ventilation assists with the removal of carbon dioxide during exercise.
  3. Increased maximal oxygen uptake and aerobic power - Regular aerobic exercise causes an increase in the number of capillaries per muscle fiber.
