Presentation Transcript

  1. Exercise and the Cardiovascular system

  2. Objectives • Be able to explain the effects of regular and long-term exercise on the Cardiovascular system in relation to: • Heart Rate • Recovery rate • Stroke volume • Cardiac output • Blood pressure • Veins and Arteries

  3. Heart and recovery rate • Normally, why does a resting HR reflect a persons fitness? • What is recovery rate (RR)? Why is this a reflection of fitness? • What athletes would you expect to have a very low Resting Heart Rate (RHR) and very fast RR? • Discuss the chart below in relation to RHR and RR

  4. Stroke Volume and Cardiac Output • Stroke volume is: • Cardiac Output is: Cardiac Output (CO) Stroke Volume (SV) Heart Rate (HR)

  5. Blood Pressure, Veins and Arteries Over weight Blockage Altitude Capillaries

  6. 7 effects of regular exercise on the CV system 1. 2. 3. 4. 5. 6. 7.

  7. Lifestyle and the CV system • Objectives • Why do we need to rest • Diet and the effect of cholesterol, High Density Lipoprotein and Low Density Lipoprotein, on blood pressure • Recreational drugs

  8. Rest • Why is rest important?

  9. 4 Negative lifestyle factors on the CV system • High Cholesterol Diet • Recreational Drugs • Sedentary Lifestyle • Stress

  10. ‘Good’ and ‘Bad’ Cholesterol • High Density Lipoprotein (HDL) • High Protein low Fat • Fruit, Vegetables, Whole grains, Legumes • Low Density Lipoprotein (LDL) • Leads to the build up of plaque • Leads to increase in blood pressure • A diet of high saturated fats is of concern as this raises the amount of Cholesterol in the blood which can lead to blockages, Strokes and Coronary Heart Disease

  11. Recreational Drugs Nicotine Tobacco Alcohol

  12. Sedentary lifestyle and Stress

  13. Homework • Read 127-149 • Complete Questions 1,2 and 3 on pg 123 • Complete worksheet on CV system and Respiratory system
