week 9

Question 1

describe early throwing ( x3)

Answer 1

• mostly arm action
• little trunk movement
• no contribution from legs

Question 2

describe proficient throwing ( steps 1-7)

Answer 2

1- weight shifts to back foot
2- trunk rotation backwards
3- employment of a backswing
4- step taken on contralateral leg which allows greater time to apply force
5- differentiated trunk rotation
6- trunk lateral bending
7- upper arms form a right angle

Question 3

what are the developmental changes in throwing? trunk, backswing, humerus, forearm, foot action

Answer 3

• trunk= no action to differentiated action
• backswing= none to full circular downward swing
• humerus= oblique to lagging
• forearm= no lag to delayed lag
• foot action= no step to long contralateral steps

Question 4

describe early kicking(x4)

Answer 4

• singular action
• no use of sequencing
• no step with non kicking leg
• knee still bent in contact

Question 5

describe proficient kicking ( x4)

Answer 5

• used predatory wind up
• leap or run up
• trunk is rotated back
• kicking legs achieves large flexion before propulsion phase

Question 6

describe early punting ( x4)

Answer 6

• ball tossed instead of dropped
• ball dropped when supported
• knee= bent at 90 degrees
• contact is often with toes

Question 7

describe proficient punting ( x4)

Answer 7

• arms are extended before dropping the ball
• body leaves ground with the hop of supporting leg
• kicking eg knee stays straight
• kicking leg rotates through nearly full range of motion

Question 8

describe early sidearm striking ( x3)

Answer 8

• looks like overarm throw
• chopping action
• little trunk rotation

Question 9

describe proficient side arm striking ( x4)

Answer 9

• step into the shot
• differentiated trunk motion
• slightly mainly horizontal
• effective sequencing of the movement

Question 10

describe early catching? (x3)

Answer 10

• central skill for many sporting activities
• children find taks difficult- need to intercept object
• early attempts= little force absorption, trap ball against chest

Question 11

describe proficient catching ( x3)

Answer 11

• catch with the hand and give the object
• master movement to intercept the object
• orient the hand appropriately
