  3. Profile of case study athlete: Cyclist – Lance Armstrong • Event: Tour de France • Characteristics of Event: • Runs for 3 weeks, consists of 20 stages - Total distance= 2657km, longest stage = 239.5km • 2004m was the altitude of the highest climb on the 2005 tour • Training:Endurance, resistance, and altitude training • Best known as: • Seven-time winner of the Tour de France (from 1999-2005)

  4. Endurance training • The main training methods used to develop aerobic capacity are: • Interval training (combining several high intensity bouts of activity) • Continuous training (consistent activity at a steady intensity) • Fartlek training (continuous activity with bursts of high intensity activity) • Resistance training (working against a weight, force or gravity, such as weight training with a low load and high reps) Which method would you recommend for improving the performance of a cyclist competing in the Tour de France?

  5. Some effects of training on the aerobic system

  6. VO2 max = amount of oxygen consumed per minute. A measure of VO2 max determines an athlete’s endurance capacity. The greater an athlete’s VO2 max, the better their cardiovascular endurance. Tests are usually done under lab conditions. However, they are: expensive, time consuming, not accessible to everyone, and physically demanding. VO2 max prediction tests include the Astrand bicycle test, 12 minute run, and beep test. Test should be specific to the athlete’s sport Measuring Training Effect

  7. Environmental considerations Altitude changes at one stage of the Tour de France • Altitude = height above sea level • As altitudes increase to above 1500m,the ability to sustain physical activity is affected. • As altitude increases, the partial pressure of oxygen decreases. How does altitude then affect performance?

  8. How do athletes prepare for competition at high altitudes? • Acclimatise = ensure body adjusts and adapts to the demands of competing in a certain climate • Increase fluid intake • Wear sun protection Are there any costs associated with altitude training?

  9. The use of technology in endurance cycling • Training innovation = an aid that assists training and competition performance.
