Sporting Example: How to get the greatest distance on a LJ

• Maximising Performance with Anterior-Posterior Impulse:

  • Mike Powell has held the long jump world record since 1991!
  • Most important aspect for long jump performance is speed of run up ie initial momentum
• Maximising Performance with Anterior-Posterior Impulse:

  • The best jumpers are able to redirect hz motion into vt motion with minimal loss of forward momentum
  • Optimal way to translate momentum
  • Similar to gait except posterior impulse much larger because change direction
• Carl vs Mike:

  • Carl Lewis
  • 8.91 m
  • Approach velocity = 11.8 m/s
  • Mike Powell
  • 8.95 m
  • Approach velocity = 12.2 m/s
