In Progress

Bio-mechanical Aspect

The parabolic throwing path is also determined by:

  • Frontal drag of the implement
  • Possible lift (e.g. headwind)

Movement Structure

All throwing events can be broken down into 4 phases:

  • Preparation
  • Momentum building
  • Delivery
  • Recovery
Preparation, Momentum building, Delivery, Recovery

Preparation

  • Gripping the implement
  • Assuming a perfect balanced position
  • Concentration

Momentum Building

The aim is

  • to increase the possible release velocity
  • to have a pre-tensed position of the body

Power Position aka « Striking position »

Link between « the momentum building phase » and « the delivery phase » is the

POWER POSITION aka “Striking position

  • Muscular tension throughout the body.
  • A balanced stance with both feet on the ground.
  • Bodyweight over the right foot, right heel lifted.
  • Right heel and left toe lined up.
  • Backward lean against the direction of the throw.

The Delivery Phase

  • blocking action of the left side
  • bow tension
  • twisted position

Arc position” in the javelin throw and comparable positions in the discus throw and shot put;

Recovery

•Discharge the remaining kinetic energy of the thrower 

  • athlete needs to avoid fouling

Recovery

Discharge the remaining kinetic energy of the thrower 

  • athlete often has personal solutions.

Fundamentals of Throwing

“Chaining method” Teaching progressions:

  • Intro to the implement (safety and grip)
  • Delivery (using front throws)
  • Power Position
  • (Recovery)
  • Momentum Building
  • Preparation Phase

Points to Emphasize

  • Optimum velocity in the momentum building phase.
  • Increasing velocity in the Power Position and Delivery.
  • A correct Power Position.
  • Successive activity of the joints involved in the final movement peaking with the maximum velocity transferred to the implement.
  • Complete extension of the body in the Delivery.
  • Developing technique with implements slightly lighter than competition weight.
  • A wide variety of exercises, implements, throwing movements, and situations.

Point

  • Introduction of competition technique to young athletes who have not reached the appropriate physical prerequisites.
  • Implements of inappropriate size, weight, or aerodynamic qualities.
  • Introduction of new technique elements before satisfactory performance of those already introduced.
  • Excessive throwing movements for athletes who have not gained the appropriate strength levels in the abdominal and leg muscles.
