Short term cardiovascular responses to exercise

1. Identify the short-term adaptations to exercise that occur in the cardiovascular system.

2. Identify and explain four short term/acute responses to exercise of the cardiovascular system.

Type your answer in the box then check your answer against the model answer.

4 marks for writing any 4 of the following:

  • Heart rate rises before exercise starts because of adrenaline released in anticipation of exercise.
  • Heart rate increases in response to intensity of exercise to increase the blood flow to the working muscles.
  • Stroke volume increases to increase the blood flow to the working muscles.
  • Increased blood pressure helps blood travel quicker to the working muscles and back to the heart to reoxygenate the blood and remove waste products.
  • Blood is re-distributed from areas where is low demand (e.g., stomach, liver) to areas of high demand (e.g., working muscles)
  • Blood directed towards the skin to increase heat loss and regulate body temperature.
