Short/Long term effects on CV system

• Immediate effect of exercise is to raise blood pressure as the heart beats faster and more powerfully
• Long-term effect of regular exercise is to reduce blood pressure
• Immediate effects of exercise on the heart include increased stroke volume, heart rate, and cardiac output
• Long-term effects of exercise on the circulatory system include hypertrophy of the heart muscle, increased stroke volume, lower resting heart rate, increased cardiac output, capillarisation, more flexible blood vessels, lower blood pressure, and improved heart health
• Short term effects of exercise on the CV system

  
  

  • Heart rate increases
  • Cardiac output increases
  • Vasodilation
  • Blood Shunting to working muscles
  • Increased blood pressure
  • Increased blood flow
• Long term effects/adaptations exercise has on the CV system

  • Heart, cardiac muscle hypertrophy
  • Decrease in resting HR
  • Increased stroke volume
  • Increase in capillary network
  • Blood vessels more elastic
  • Increase in red blood cells
• A short term effect of exercise on the CV system is vasodilation because...


  blood vessels widen to let off heat produced by working cells
• A short term effect of exercise on the CV system is blood shunting because...

  blood moves to working muscles and away from inactive areas
• why does blood pressure increase during immidiate exercise?

  To supply more oxgyen to working muscles
