THROW Pattern PUSH Pattern

1
THROW Pattern PUSH Pattern

• proximal segments in front of projectile with
  distal segments behind projectile
• sequential for ? v
• curvilinear path
• mostly wheel-axle

• all segments behind pushing the projectile or
  ahead pulling the load
• simultaneous for ? F
• rectilinear path
• mostly lever motions

2
Preparation Phase 1. Rotate torso so that contra
lateral shoulder faces target 2. Step forward
with contra lateral leg
3
Hips Rotate whileupper torso and arm lag behind
4
1. HIPS are stopped while upper torso and
shoulders continue to rotate 2. Upper torso and
shoulders are stopped once they are aligned
with hips/lower torso
5
Wheel-Axle medial rotation of the shoulder
6
Wheel-Axle pronation during release phase
7
v r ? r is increased about both longitudinal
axis of torso via elbow extension
8
Release Point is beside torsonot in front of
torso

Mechanical Purposes of PUSH

• 1.
• 2.
• 3.

10
Push Pattern for Force Activities

• maximum strength movements demand simultaneous
  segmental rotations
• move in a rectilinear path
• minimize acceleration in movements to avoid
  injury and to comply with Force/Velocity principle

11
PUSH Pattern Power Activities

• Power movements require both F and v
• moving a resistance fast requires higher F max
• rapid acceleration in a short period of time
• strength-dominant P (e.g. shot putting)
• speed-dominant P (e.g. jump, start, strike, throw)

12
Power in Jumping

• PUSH body into space via segmental rotations
• large F required to achieve maximum vertical or
  maximum horizontal distance
• takeoff of a jump for maximum DistanceVERT
• bodys C of G has high VVERT moderate VHORZ
• takeoff of a jump for maximum DistanceHORZ
• bodys C of G has high VVERT high VHORZ

13
Jumping Motions Sequence

• 1. Massive segments/trunk _at_ open end of chain
• 2. Small segments/feet _at_ closed/fixed end
• 3. ideal direction of F is through bodys CG
• 4. initial shoulder flexion exerts downward F
• 5. stopping shld. flexion initiates trunk
  extension
• 6. Shld. flexion trunk extension loads legs
• 7. Loading of leg muscles increases ROM and
  elicits elastic recoil in hip knee extensors

15
Punch/Strike Power/Accuracy

• F v accuracy important in punch or strike
• Throw/Push Continuum involved in Punch/Strike
• v is initiated and increased using the kinetic
  link and a curvilinear path v r?
• F and accuracy is achieved by changing to a
  rectilinear path near the end of the ROM, just
  prior to contact/impact

16
Accuracy Accuracy with v

• Consistency in movements key to success
• straight line motion just prior to, during, and
  just after release/impact
• rectilinear path for projecting for short
  distance
• curvilinear then a flat space to a rectilinear
  path just prior to and during release/impact
