Common General Concepts
General Concepts‐There are several key concepts that are
common to all athletic endeavors
![Page 5: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/5.jpg)
General Concepts Across Athletics
• Balance and Positioning• Temporal Considerations (Rhythm)
• Order of execution
![Page 6: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/6.jpg)
Balance and Positioning
• Postural integrity– Head Alignment
– Pelvic neutrality• Turning
– Core Strength
– Proprioception
![Page 7: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/7.jpg)
Balance Continued• Center of Mass
– Changes according to body position
– Can be outside body
• Conservation Strategies– Base of Support– Lowering – Opposing limbs
• Efficiency of movement– Postural integrity and
conservation of balance are key factors
![Page 8: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/8.jpg)
Temporal Considerations
• Overcoming inertia– Slow to fast with good positioning
• Uniform Acceleration– Shift through the gears
![Page 9: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/9.jpg)
Order of execution
• Order in which human movement occurs– Sequential firing
• Large and proximal joints initiate
• Small and distal follow
• i.e. Vertical leap
![Page 10: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/10.jpg)
Technical Commonalities
![Page 11: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/11.jpg)
Phases of Throwing
• Preparation
• Power Position
• Delivery/Recovery
![Page 12: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/12.jpg)
Preparation• Glide/Rotation/Approach run
• Designed to provide momentum and velocity to thrower and to the implement– Newton’s Second Law– Elite throwers do not let the implement stop
• Moves the thrower to correct delivery position– Foul line, toe board, etc
• Path of the implement is never straight line– Path of athlete, i.e. 100m
![Page 13: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/13.jpg)
Power Position
• Foot Position– Stagger‐Toe to instep– Ball of the foot or flat foot?
• Weight Distribution– Majority of weight over back foot– Rear leg under COM
• Shoulder/hip separation– Keeps implement “back”
![Page 14: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/14.jpg)
Delivery
• Ultimate position that the implement leaves the thrower/implement system
• Positioning dictates:– Height of release– Angle of release– Implement positioning
• Aerodynamics
• Follow through/Projection– Where do limbs stop
![Page 15: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/15.jpg)
Recovery
• Strategies used to prevent a foul– i.e. switching feet in the ring, follow‐through on runway
![Page 16: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/16.jpg)
Additional Technical Commonalities
• Weight Transfer– Strategy used to elongate duration of force application on the implement
– Weight moves from the back leg to front leg
![Page 17: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/17.jpg)
Additional Technical Commonalities
• Blocking– Stopping of the non throwing side in order to increase velocity of the implement
– Can help to preserve balance and positioning
![Page 18: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/18.jpg)
Additional Technical Commonalities
• Turning– Oscillations occur in the hips, torso, arms and legs– Takes place proximally to distally– Provides force application to the implement– Squares thrower to sector for proper delivery position
![Page 19: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/19.jpg)
Additional Technical Commonalities
• Extension• Limbs extend proximally to distally• Lower body:
– Vertical force application– Turn initiates movement, extension follows
• Upper body:– Horizontal force application
![Page 20: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/20.jpg)
Additional Technical Commonalities
• Separation– All throwers should be closed in some way– Refers to shoulder girdle angle vs hip angle– Elongates path of force application– Promotes torque in the mid section
![Page 21: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/21.jpg)
Additional Technical Commonalities
• Free Arm Action
– Extends and traces a path for the implement
– Speeds up the implement
– Sets up the upper body for block
![Page 22: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/22.jpg)
Additional Technical Commonalities
• Stretch Reflex– A stretched muscle provides a harder contraction– Example: Pectorals can act as a rubber band
![Page 23: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/23.jpg)
Creating a Throwing Model
![Page 24: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/24.jpg)
Creating a Throwing Model
• Shot Put/Discus/Javelin delivery systems have their roots in the Double Pivot drill.
• Utilize the drill to teach the skill or rehearse the skill– Use throughout the year
![Page 25: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/25.jpg)
Step 1 –Set up and Posture
• Assume the stance• Line up feet• Step out• Saddle up
![Page 26: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/26.jpg)
Step 2—Weight Shift
• Tap/Tap
![Page 27: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/27.jpg)
Step 3—The Turn
• Start with upper body 90 degrees from sector• Pivot body from torso with weight shift
– Feet turn in synchronicity
• Front turns and foot grounds– Quad is flexed – Establishes lower body block
• Back knee closes to midline of body• Tap of rear leg still exists
![Page 28: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/28.jpg)
Step 4—Full Drill
• Begin with shoulders at 180 Degrees
• As proficiency increases, minimize pause
![Page 29: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/29.jpg)
Upper Body Considerations
• Upper body timing can be taught with full drill– Cone/Bowling Pin—relationship to COM– Block THEN Deliver
• As pivot takes place, non‐throwing arm opens• Upper body block then occurs with the lower body
![Page 30: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/30.jpg)
Variations of the Double Pivot• Does not need to be event specific
– Teaching a skill– Bilateral
• Varying implement– Cone/Bowling pin‐far from COM– Shot Put/Med Ball‐ close to COM
• Dynamic additions– Hop/mini glide/crossover
• Weight Room adaptations– Specific strength—Barbell– Small plyo box/toe board
![Page 31: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/31.jpg)
Implementation of a Coaching Strategy
![Page 32: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/32.jpg)
Throws
• Each event 2‐3x per week• 15‐30 repetitions• Early season:2 or more technical sessions with cones/pins/med balls
• As season progresses, utilize varied implements less– Skill acquisition
![Page 33: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/33.jpg)

Weight Room
• Utilize the weight room for more than conditioning
• TEACH movements and apply them to each event
![Page 35: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/35.jpg)
Specific Weight Room Exercises
• Explosive Triple extension– 1‐2x per week w/ 48‐72 hrs between– Olympic lifts/Jumps
• Strength Triple extension– 1‐2x per week w/ 48‐72 hrs between– Powerlifting Movements
• Body Building/Ancillary– Either GS day or spread out
• Core/Rotary/Forearms(grip)/Calves– Address each day
![Page 36: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/36.jpg)
Identify Strategy for Multiple Throws Athletes
• Identify Training Age• Most HS Athletes are younger than you think!• Part Whole Part
– Introduce Skills– Incorporate into full throw– Take a needs assessment
![Page 37: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/37.jpg)
Strengths vs Weakness
• Primary vs secondary events– Work toward equality
• Needs assessment– Odds are that similar technical faults occur across all of the events
• Make your weaknesses into your strengths!
![Page 38: Commonalities of the - USTFCCCA · 2012. 12. 12. · Additional Technical Commonalities • Separation – All throwers should be closed in some way – Refers to shoulder girdle](https://reader034.fdocuments.in/reader034/viewer/2022051322/602d315f2c011a0c097f35d7/html5/thumbnails/38.jpg)
Final Note: Focus of Practice
• Work the commonalities during each practice
• Some of your best shot put practices you never pick up a shot put!
