Movement analysis

Question 1

ball and socket

Answer 1

a joint that allows movement in every direction

Question 2

hinge joints

Answer 2

a joint that that allows movement in only one direction

Question 3

agonist

Answer 3

The muscle that is moving/ contracting in a movement

Question 4

antagonist

Answer 4

The muscle that is relaxing in a movement

Question 5

flexion

Answer 5

decreasing angle @ joint

Question 6

extension

Answer 6

increasing angle @ joint

Question 7

adduction

Answer 7

moving limb towards midline

Question 8

abduction

Answer 8

moving limb away from midline

Question 9

horrizontal adduction

Answer 9

moving limb forwards and towards midline

Question 10

horrizontal abduction

Answer 10

moving limb backwards and away from midline

Question 11

planterflexion

Answer 11

pointing your toes downwards

Question 12

dorsiflexion

Answer 12

pointing your toes upwards

Question 13

the 3 types of contractions

Answer 13

1. concentric
2. eccentric
3. isometric

Question 14

concentric contraction

Answer 14

muscle fibres shorten

Question 15

eccentric contraction

Answer 15

muscle fibres lengthen

Question 16

isometric contraction

Answer 16

muscle fibres do not chnage in length

Question 17

what happens in weighted, downwards movements

Answer 17

• the body has to break
• agonist and antagonist swap over

Question 18

frontal plane - sagittal axis

Answer 18

The plane/axis that splits the body into front and back.
- adduction and abduction
- sideways movements (cartwheel)

Question 19

sagittal plane - transverse axis

Answer 19

The plane/axis that splits the body into left and right.

• flexion and extension
• forwards movements (somersault/ running)

Question 20

transverse plane - longitudinal axis

Answer 20

The plane/axis that passes through the middle of the body, so dividing it into the bottom and top.
- (horizontal adduction and abduction)
- pirouette
