  1. Altitude training

  2. Altitude training Learning Outcomes: • All are able to discuss the benefits of fitness training methods and explain what altitude training is • Most can understand the importance of thermoregulation. • Most are able to analyse the benefits and drawbacks of altitude training to an athlete. • Some can use this knowledge to answer an examination question in detail.

  3. Altitude training • Homework: • Complete 14 mark question on altitude training • Complete examination question on thermoregulation • Complete notes and reading on periodisation • REVISE FOR MOCK

  4. Altitude training • Starter activity – complete Training letter choice activity • Complete benefits of the different types of training activity

  5. Altitude training What is it? • Athletes chose to train at level normally over 2000m above sea level • Usually for at least 30 days • Three phases - acclimatisation - primary training - recovery

  6. Altitude training Who? • Endurance athletes • Athletes competing at altitude (e.g. World Cups) • altitude training

  7. Altitude training Why? • Partial pressure of oxygen is lower (less oxygen available) Resulting in? • Body struggles to produce required amounts of energy • This triggers physiological adaptations • Body produces EPO (erythropoietin)

  8. Altitude training Immediate effects: • Increase in breathing • Increase in HR

  9. Altitude training Long Term effects (Advantages) • Increased concentration of RBC’s • Increased concentration of Hb/Myoglobin • Increased capacity to carry O2 • Increase in blood viscosity • Increased capillarisation • Increased tolerance to lactic acid (delay OBLA)

  10. Altitude training Returning to Sea level • Higher RBC count and Hb concentration remain for 6-8 weeks. • This benefits ability to carry oxygen for endurance athletes

  11. Altitude training Hinders performance? • Altitude sickness • Lethargy • Insomnia • Train at same intensity is difficult/detraining may occur/loss of fitness • Dehydrated • Psychological problems linked to travel/time away from home • Benefits lost quickly when back at sea level

  12. Altitude training Alternative methods • Hypoxic tents/altitude tents/ oxygen tents • Live High Train Low - most recent evidence suggests that living at altitude, yet training at sea level is the most beneficial

  13. Altitude training – Mini Plenary activity Elite athletes spend considerable time developing their fitness, using a variety of methods, in order to produce peak performance. • (i) Explain why some athletes, such as marathon runners, may choose to spend time training at altitude. (3 marks) (ii) What are the potential problems associated with altitude training? (3 marks)

  14. Altitude training 4 (a) (i) 1. Improved endurance/stamina/aerobic capacity/VO2 max; 2. Reduced concentration/partial pressure of oxygen at altitude; 3. Compensation through increased red blood cells/haemoglobin; 4. Erythroprotein; 5. Enhanced oxygen carrying capacity (on return to sea level) 3 marks (ii) 1. Reduced pO2 – training very hard; 2. Loss of fitness/detraining effect; 3. Increased lactate production/accumulation; 4. Altitude sickness/weeks to acclimatise; 5. Solution – live at altitude and train at sea level; 6. Other physiological e.g. blood viscosity/psychological/social/environmental factors. 3 marks

  15. Thermoregulation during exercise • Read hand outs and complete worksheet to demonstrate understanding of thermoregulation key terminology.

  16. Plenary activity • What part of the brain controls thermoregulation? • Hypothalamus • What is the main job of the thermoregulatory centre? • Maintain the core temperature • During exercise which mechanism is the most effective for cooling? • Sweat evaporation • What happens to the body if it gets dehydrated? • Blood volume decreases, performance decreases (insufficient oxygen available)

  17. Altitude training Learning Outcomes: • All are able to discuss the benefits of fitness training methods and explain what altitude training is • Most can understand the importance of thermoregulation. • Most are able to analyse the benefits and drawbacks of altitude training to an athlete. • Some can use this knowledge to answer an examination question in detail.
