IAAF CECS Level II Event Specific Theory 2
Whole Sequence
The javelin throw is divided into the following phases:
• Approach
• 5-Stride Rhythm
• Delivery - which is part of the 5-stride rhythm
• Recovery.

The Grip
Objective
• To grasp the javelin firmly and comfortably
Technical CharacteristicsThe grip:
• Javelin lays diagonally in a relaxed hand and palm faces upward
• Choice of two grips:
1. Thumb and first finger grip
2. Thumb and second finger grip.

IAAF CECS Level II Event Specific Theory 4
Approach Phase
Objective
To accelerate the thrower and javelin
Technical Characteristics
• Javelin is held horizontally over the shoulder
• Top of the javelin is at head height
• Arm is held steady - no forward or backward movement
• Acceleration run is relaxed, controlled and rhythmic - 6-12 strides
• Acceleration to optimum speed - which is maintained or increased
in the 5-stride rhythm.

IAAF CECS Level II Event Specific Theory 5
5-Stride Rhythm Phase
Withdrawal
Objective
To position the javelin correctly for the delivery
Technical Characteristics
• Withdrawal starts on landing of the left foot
• Left shoulder faces direction of the throw - left arm is held forward for
balance
• Throwing arm extends backwards during first and second strides
• Throwing arm is at shoulder height or slightly higher after withdrawal
• Tip of the javelin is close to the head in line with the eye.

IAAF CECS Level II Event Specific Theory 6
5-Stride Rhythm Phase
Impulse Stride
Objective
To position and prepare the body for the delivery
Technical Characteristics
• Drive-off is active and flat from whole sole of left foot - no loss of velocity
• Body leans backwards - legs and trunk ‘overtake’ the javelin
• Left shoulder and head face the direction of the throw
• Impulse stride is longer than the delivery stride.

IAAF CECS Level II Event Specific Theory 7
Delivery Phase - Transition
Objective
To transfer velocity from the legs to the trunk
Technical Characteristics
• Right foot is placed flat at an acute angle to the direction of the throw
• Legs have ‘overtaken the trunk’
• Axes of the shoulder, javelin and hip are parallel
• Right knee and hip push forwards actively
• Throwing arm remains extended.

IAAF CECS Level II Event Specific Theory 8
Delivery Phase - Power Position
Objective
To transfer velocity from the trunk to the shoulder and arm
Technical Characteristics
• Placement of left foot is active and solid and left side is stabilised
• Muscles in the front of the body are pre-tensed in the ‘Arc’ or
backward ‘C’ position
• Throwing shoulder pushes forwards
• Throwing elbow turns inwards, palm remains up.

IAAF CECS Level II Event Specific Theory 9
Delivery Phase - Final Arm Movement
Objective
To transfer velocity from the shoulder and arm to the javelin
Technical Characteristics
• Right elbow draws forwards and upwards alongside the head
• Trunk moves forwards and throwing elbow straightens explosively
• Left side of the body is blocked by solid left leg and ‘fixing’ of bent left
elbow close to trunk
• Right foot turns but maintains ground contact until the javelin is
released.

IAAF CECS Level II Event Specific Theory 10
Delivery Phase - Final Arm Movement
Objective
To transfer velocity from the shoulder and arm to the javelin
Technical Characteristics
• Right foot turns on its outside edge and is dragged behind (1)
• Trunk leans slightly to left, right shoulder is directly over left foot (2)
• Throwing arm should be as close to vertical as possible at release (3).

IAAF CECS Level II Event Specific Theory 11
Recovery Phase
Objective
To stop the forward movement of the body and avoid fouling
Technical Characteristics
• Distance from foot of the brace leg to the foul line is 1.5m - 2m
• Legs are reversed quickly after the release
• Right leg is bent to control ‘stop’
• Upper body is lowered and left leg naturally swings backwards.

Foot Placement
Objective
To create velocity and transfer it to the javelin
Technical Characteristics
• 5-stride rhythm comprises:
– withdrawal
– impulse stride
– delivery
• Speed increased to optimum level - based on individual capability.
