CSEP CPT theory - Core competency 1 - anatomy, physiology, exercise physiology questions with correct answers

Cardiac output - Answer The product of heart rate and stroke volume Typical values for cardiac output - Answer At rest - 5 L/min during more intense physical activity - 20-30 L/min Stroke volume - Answer Volume of blood that is pumped by the heart with each contraction Typical values for stroke volume - Answer 60-80 ml of blood - increases during physical activity until intensity reaches 50% of VO2 max, after that HR increases to produce the cardiac output required to meet the required oxygen demand. Effect of training on stroke volume - Answer Stroke volume increases after a period of consistent training Blood pressure - Answer The pressure that the blood exerts on the walls of the blood vessels and reflects the efficiency of blood flow through the cardiovascular system Systolic blood pressure - Answer The highest pressure just after the heart contracts Diastolic blood pressure - Answer The lowest pressure just before the heart contracts
