Effects of regular participation in – and long-term effects of participation in – exercise and physical activity:
cardiac output HR x SV = CO
 - decreased resting heart rate
 - faster recovery
 - increased stroke volume
 - increased size of heart
 - effects on blood pressure
 - healthy veins and arteries)

 

Rest (rest required for adaptation to take place, time for recovery before next exercise session)


Diet (effects on blood pressure and cholesterol – HDL and LDL)
