1. Cardio-Vascular Response to Exercise

2. Long Term Responses of Cardiovascular System to Exercise
The Heart
Increase in max HR as myocardium (heart muscle) becomes fitter.
Increase stroke volume
Decrease in resting HR
Bradycardia
Increase in potential cardiac output during exercise
The Vascular System
Increase in number of red blood cells (and haemoglobin)
Increased tolerance for lactic acid
Increased capilliarisation
Increase in VO2 max (and a-vo2 difference)

3. Response of Cardiovascular and Cardio-respiratory systems to a warm up
Increase in body temperature
Increase in heart rate and cardiac output
Increase in minute ventilation
Increase in blood pressure to force blood around body more quickly
Release of adrenaline
Blood shunting via vasoconstriction and vasodilation of arterioles
More O2 delivered to working muscles

4. Examine the purpose of warming up to improve cardiac function during sporting activity. (6)
