Test Lock and Release (Delivery)
Agenda
1st QUESTION: What defines the "Block" of the left leg for a right-handed javelin thrower?
Heel thrust forward and knee fully extended and stiff
Continuous impulse with both legs flexed
Vertical jump to increase the height of the throw
Gently support the foot to cushion the impact
2nd QUESTION: What effect does the blocking have on the inertia transfer?
Accelerate the race more before the launch
Increasing biceps work on the final thrust
Braking downward to transfer speed to the trunk and arm
Allowing a rotation of the body without stopping
3rd QUESTION: What happens if the blocking leg is flexed in the support?
Height is gained and the exit angle is improved
Increases the stability of the support by cushioning
Knee is protected from impact without loss of energy
Energy is dissipated and the javelin loses meters drastically
QUESTION 4: How do you describe the Tight Bow position?
Hips set back and chest tucked in to hide the javelin
Left leg locked, hips forward and chest open upward
Both arms in front to guide the tip of the implement
Trunk inclined laterally and elbow below the shoulder
5th QUESTION: How should the elbow of the throwing arm pass in the technical gesture?
High, over the shoulder, as if throwing over a goal
Low, at waist height to avoid tension
Fully extended before moving the trunk
Sticking to the side for a lateral throw
QUESTION 6: What is the risk and effect of lowering the elbow during the throw?
Larger exit angle and more parabolic trajectory
Less stress on the shoulder and more stable flight
Risk to the ulnar collateral ligament and flat flight of the javelin
Improved lockout and transfer of inertia to the trunk
7th QUESTION: What is the optimal angle of release in the final whip?
Less than twenty degrees for penetrating flight
Exactly forty-five degrees for maximum distance
More than fifty degrees to gain height
Between 32 and 36 degrees depending on the text
8th QUESTION: What does the recovery consist of immediately after releasing the javelin?
Jump forward without slowing down so as not to lose momentum
Invert the legs, pass the right leg in front and brake without stepping on the line
Turn on the left heel to return to the start
Accelerate a few more steps to stabilize the flight
