Ergogenic aids for exercise and sports performance

  1. 1. Ergogenic Aids for Exercise and Sports Performance Anabolic Steroids, HGH and EPO
  2. 2. https://www.youtube.com/watch?v=VvKQ2kVB wTU
  3. 3. Aim: To introduce students to the effects and implications of using ergogenic aids for exercise and sports performance Objectives: By the end of this session students should be able to: • Name 3 different banned ergogenic aids • Describe the positive performance effects of the 3 different ergogenic aids • Identify 1 sport that benefits from 1 particular ergogenic aid • Evaluate the negative health implications of using these banned ergogenic aids
  4. 4. Androgenic Anabolic Steroids (AAS) • What are (AAS)? • (AAS) are drugs that resemble androgenic hormones • Androgenic Hormones (Male Hormones) • Male hormones are responsible for creating Testosterone
  5. 5. Human Growth Hormone (HGH) • Is a peptide hormone that occurs naturally in the body • Stimulates muscle growth through increases in testosterone production and cell reproduction • Has similar performance benefits to that of (AAS)
  6. 6. What Does Testosterone do? • It is responsible for increased androgenic and anabolic development (Fahey, 1998) • Androgenic (effects sexual characteristics, penis growth, hair growth, aggressiveness) • Anabolic (accelerated muscle and bone growth and red blood cell development)
  7. 7. How Does this improve sporting performance? • Increased Muscle Growth • Enhanced Strength and Power • Anti- Catabolic • Improves Recovery after intense exercise and helps fat loss • Increased Red blood cell count • Enhanced endurance and recovery from exercise
  8. 8. Which Sports Benefit from these Physiological enhancements? • Power Lifting • Sprinting • Wrestling • Boxing • Bodybuilding • Rugby
  9. 9. What is EPO? • Erythropoietin (EPO) is a hormone that is produced by the kidneys • It is injected under the skin • Increases red blood cell count
  10. 10. Blood Doping • Most commonly involves the removal of 2 units of healthy blood weeks before competition • The blood is then frozen up until 1-2 days prior to competition, where it is thawed and injected back into the athlete • Red blood cell count is maximised and not lost through blood becoming toxic from the stresses of training
  11. 11. What do Red Blood cells do? • More Red Blood cells means more haemoglobin • Haemoglobin binds to oxygen and carries it from the lungs to the muscles • EPO supplementation therefore allows extra oxygen to be transported to the working muscles
  12. 12. Effects of (EPO) and Blood doping on performance • Increases the amount of oxygenated blood carried to the muscles • Therefore an athletes VO2 Max is greatly increased • A larger supply of oxygenated blood means waste products like lactic acid can be removed quicker after exercise • Improves Recovery and performance in endurance events
  13. 13. Which Sports Benefit? • Cycling • Distance Running • Triathlon • Cross Country Skiing • Football • Rugby • Crossfit • Boxing
  14. 14. TASK 1 1. Describe the physiological adaptations that occur to the body after supplementing with (AAS), HGH, (EPO) and Blood Doping 2. Explain how each one improves performance 3. Identify a specific sport that would benefit from these performance improvements
  15. 15. The Implications of Ergogenic Aids use in Sport • What do we mean by Implications? • Implications are effects or consequences that may happen in the future https://www.youtube.com/watch?v=zbTyCe2db Rk
  16. 16. (AAS) and (HGH) • Hypertrophy of the heart, increased risk of Heart failure and cardiovascular disease • Increased growth to organs can cause organ failure • Acromelagy – Excessive tissue growth, particularly effecting bones and joints
  17. 17. (EPO) and Blood Doping • These methods increase red blood cell count to abnormally high amounts • This Causes a thickening of the blood • Which puts pressure on the heart, as it has to pump harder to circulate the blood around the body • This can lead to serious cardiovascular disease, Blood Clots, Heart Attacks and Stroke
