1. Shot Put A Comparison of the Rotational and Glide Techniques
by: Jared Garcia and Christy Beune

2. Objectives Competition: Throw the shot the farthest distance
Produce the greatest amount of work on the shot

3. Special Characteristics
Definition
greater height and velocity=greater shot distance
PE=wt. · h KE=1/2mv2
W = KE + PE
greater work
Shot weight:
4 kg (8.8 lbs.) for women
12 lbs lbs. for men from high school to college.

4. 6 Phases of the Rotational technique
Phase Objectives:
#1 Preparation - concentrate
#2 Preliminary Speed - Motion
#3 Building Momentum - Accelerate
#4 Transfer - Tension
#5 Delivery - Ejection
#6 Recovery - Stabilization

5. Phase #1 - The Preparation Phase
From choosing the implement to the starting position
holding the shot
shot rests on base of fingers (ball of hand)
arm relatively horizontal to ground
neck placement
shot pushed against neck, underneath chin

6. Phase #2 - Preliminary Speed Phase (entry)
From the starting position to the end of the left foot pivot
Thrower and implement move at the same speed

7. Phase #3 - Building momentum phase (drive)
From left foot pivot to right foot landing
Right leg moves faster than implement

8. Phase #4 - Transfer Phase (power position)
From right foot landing to left shoulder opening through “power position”
Apply forces to the thrower

9. Phase #5 - Delivery phase
From left shoulder opening to implement leaving the hand
Apply forces to the implement
Optimum release angle 41

10. Phase #6 - The Recovery Phase
From implement leaving the hand to balanced position in the circle

11. 5 Phases for the Glide Technique
#1 Crouch start
#2 Drive
#3 Glide
#4 Power position
#5 Delivery

12. Phase #1 - Crouch Start
Look towards back of ring (Hips need to be in front of upper body)
All weight over one leg (on toes) with kick leg free

13. Phase #2 Drive Transfer weight from toes to heel
Eyes stay looking back
Kick Leg hard to toe board
Keep free arm back (Guide)

14. Phase #3 Glide Land with center of gravity over right foot
Drive hips forward (they will be facing the side of the ring)

15. Phase #4 Power Position Rip free arm across chest Turn hips forward
Beginning the release of the shot

16. Phase #5 Delivery Transfer weight from right leg to left leg.
Free arm moves down side of body
On toes at this point
Arm over toeboard

17. Summary Glide Rotational Most common for beginners
Advantageous for tall massive throwers
Harder to generate more velocity
Rotational
Easier to learn for those who have mastered the glide
Easier to generate velocity
Difficult recovery phase
Provide an efficient way of getting the farthest put
