What Kills Speed

Pole Vault, the Braking Step, back kick, Upward Jumping, swirling. Each one adds time.

Founder method

The Pole Vault

The cut step starts too far from the hurdle.The hip swing expands into a full or reaching step, landing ahead of the center of mass.The planted leg vaults the athlete over.

Coach notes
  • It replaces down-and-back propulsion with braking and extended support. It can be seen in takeoff position, contact relative to center of mass, ground-contact time, flight time and clearance path.

The Braking Step

A contact ahead of the center of mass slows the athlete like a car brake.It is the cardinal sin.Through hurdles one to three, every ground contact belongs behind the center of mass.

Coach notes
  • The point where that rule changes later in the race has not been stated.

  • Unresolved Whether and where the behind-center rule changes after H3.

More Ways to Lose Time

Back kick kills speed.Jump is a bad word.No swirling, no twirling.Arms flying out to the sides like a T, like an airplane, bleed forward momentum.

Wanted

  • frontside mechanics
  • Pop
  • straight lines
  • arms tucked, sprint arms

Rejected

  • back kick kills speed
  • Upward Jumping
  • swirling, twirling
  • arms out to the sides like an airplane
Anti-patterns
Coach notes
  • The airplane-arms fault comes from a third-person summary of a founder video review, where he asks for sprint arms tucked tighter to the body rather than flying out wide.

The Scorecard

Total flight time across the hurdles.Total ground-contact time across the race.

Coach notes
  • The founder proposes these two cumulative measures as the race's scorecard and the way to expose Pole Vault cost. Definitions, instruments and reliability still need to be set.
  • The claim that inaccurate takeoff doubles or more than doubles clearance-related contact time is unverified.

  • The Cut Step -- At hurdle speed there is no time for a full cycle. The cut step is an abbreviated, stiff strike from the hip.
  • Stiffness, Pop and Bounce -- Stiffness is the hurdler's superpower. Pop is good, jump is bad, and the bounce goes forward down the track.
  • Hitting the Track -- Hit the track before you hit the track. The effective strike lands slightly behind you and sends you down the track.
