The Model
Model (definition)
●
– “A system or thing used as an example to follow or imitate.”
ALWAYS HAVE A MODEL
●
– Guides athlete development
– Structures coaching progression
– Provides feedback
Our high jump models
●
– Derek Drouin (takeoff)
– Stefan Holm (bar clearance)
– Antonietta DiMartino (complete jump, female)
Important Concepts
Vector
●
– A measurement that has both magnitude and direction
– Examples:
Velocity
●
Acceleration
●
Center of Mass
●
– A point representing the mean position of the matter in a body or system.
Angular Momentum
●
– Figure Skater Example
Arms out = slow
●
Arms in = fast

Approach
What is the purpose/goal of the approach?
●
– Posture
The approach must prepare the athlete for proper take-off positions
●
The single most important result of the approach is the athlete's body
●
position leaning away from the bar at take-off
– Tempo/Rhythm
The approach must build toward
●
the takeoff
– Speed
Less critical for younger jumpers,
●
but necessary for elite-level heights
●
Approach
Approach Length
●
– A longer approach almost always equates to more speed at takeoff, and
too much speed will limit performance, especially for a younger athlete
– Common stride counts
High School = 8-10
●
College = 8-12
●
Elite = 10-14
●
Approach
Approach Phases
●
– Straight
Generate enough speed so as to not have to over-work the corner
●
Generate rhythm
●
The initial phase of the high jump approach is among the most
●
varied technique in all of track and field; it is very much affected by
athlete comfort and preference
This is the part of the approach most prone to inconsistencies
●
– Corner
Run a true corner to generate the desired body lean
●
– Cannot be an “L” or anything comprised of straight line segments; this
will take the athlete out of the desired body position
A quality high jump cannot be achieved without a quality corner
●
Components of the High Jump
i. Approach
ii. Takeoff
iii. Bar Clearance
Takeoff
What is the goal of the takeoff?
●
– Add a vertical component to the athlete's velocity
Takeoff – in any jump – is the process of increasing the angle of the
●
athlete's velocity vector
“Convert” or “block”
