Flashcards in 6 - analysis of movement Deck (31):
1

What are articulations?

Joints

2

Define the agonist mucles

The muscle/muscle group which is mainly responsible for the movement

3

What isometric contraction?

muscle contraction but not movement occurs
eg, wall sit

4

What isotonic contraction?

muscle changes length when contracting
movement is brought about

5

What is a concentric contraction?

A muscle shortening as it contracts

6

What is eccentric contraction

A muscle lengthening as it contracts

7

What is the sagittal plane?

the plane the splits the body into left and right

8

What is the frontal plane?

the plane that splits the body into front and back

9

What is the transverse plane?

The plane that splits the body into top and bottom

10

What is the frontal axis?

The axis that passes from from front to back

11

What is the transverse axis?

The axis that passes from side to side

12

What is the longitudinal axis ?

The axis that passes from top to bottom

13

What are the pairs of planes and axis?

Sagittal plane and transverse axis.
Frontal plane and frontal axis
Transverse plane and longitudinal axis

14

What movement does the sagittal plane and transverse axis make?

Flexion and extension movements
Forwards and backwards movements

15

What Movements does the frontal plane and frontal axis make?

Adduction and Abduction
Side to side movements

16

What movements does the transverse plane and longitudinal axis make?

Rotational movements

17

Name the types of joint and where to find them?

Hinge - Elbow, knee
Ball & Socket - Shoulder, Hip

18

Describe plantarflexion and dorsiflexion

Plantarflexion is point the toes towards the ground
Dorsiflexion is pointing the toes towards the sky

19

Define hyper-extension

When the angle between the bone and the joint exceeds 180

20

Define horizontal hyper extension

When the arm is taken back behind the shoulder but parallel to the ground. (preparing the do an overarm throw)

21

Describe horizontal flexion and extension

(ARM)
Horizontal extension - moving arm away from your body when it is horizontal
Flexion - moving in across your body horizontally

22

What are articulating bones?

Bones that meet at a joint

23

Describe a first class lever

The fulcrum lies in the middle.

24

Describe a second class lever

The resistance lies in the middle

25

Describe a third class lever

The effort lies in the middle

26

Describe the way to remember what lever is working.

123, FRE

This tells you what factor lies in the middle of each lever.

1 is the fulcrum

2 is the resistance

3 is the effort

27

What are the fulcrum, resistance and effort in a level?

Fulcrum - Joint

Effort - the muscle

Resistance - the weight you're moving

28

Give examples of each lever.

1st class lever - throwing, pressups, headstand to handstand.

2nd class- only occurs at the foot/ankle , running, kicking, jumping.

3rd class- bicep curl,

29

Define the force arm

Distance of the force/effort/muscle from the fulcrum.

30

Define resistance arm

The distance between the resistance and the fulcrum

31

What's the mechanical advantage and disadvantage of having a short force arm but a long resistance arm?

A short force arm means it can apply much force to move the object, its not very strong.

A long resistance arm means that a large range of movement, and can lift object quickly

Eg) in a 3rd class lever, you can lift a lot of weight but you can do it quickly
