Q

Name two examples of a ball and socket

A

Hip, shoulder

29
Q

What is a hinge?

A

Joints that allow you to move in only one direction. They allow flexion and extension of the joint.

30
Q

What is a ball and socket?

A

They allow movement in almost every direction. The joint is made up of the round end of one bone that fits into a small cup-like are of another bone.

Q

What type of joint allows the greatest range of movement?

A

Ball and Socket

32

A

Flexion, Extension, Abduction, Adduction, Planar flexion, Rotation, Dorsiflexion

33
Q

What is flexion and what is an example of it?

A

Elbow flexes whilst performing a bicep curl

34
Q

What is extension and what is an example of it?

A

Straightening a joint and the angle of the joint increases.

The elbow whilst throwing a shot put

35
Q

What is abduction and what is an example of it?

A

Movement away from the midline of the body which occurs at the hip and shoulder.
Performing a jumping jack

36
Q

What is adduction and what is an example of it?

A

Movement towards the midline of the body which occurs at the hip and shoulder.
Jumping in from a jumping jack

37
Q

What is Rotation and what is an example of it?

A

The limb moves in a circular movement around a fixed joint.

When performing a drive shot in golf

38
Q

What is plantar flexion and what is an example of it?

A

Pointing the toes, the movement only occurs in the ankle

For example tendue in ballet (pointing feet )

39
Q

What is dorsiflexion and what is an example of it?

A

The foot moving towards the shin which only occurs in the ankle
Pulling your toes up to stretch

40
Q

What are the two muscles in the arm?

A

Bicep, Tricep

41
Q

What are the five muscles in the leg?

A

Hamstrings, quadriceps, hip flexors, tibialis anterior, gastrocnemius

42
Q

What does the sternocleidomastiod do and what is an example of it in sport?

A

Helps with the breathing process

All sports but especially endurance events

43
Q

What does the deltiod do and what is an example of it in sport?

A

Abduction from the shoulder (moving the arm outwards and away from the body)
Outward arm action in a jumping jack

44
Q

What does the rotator cuffs do and what is an example of it in sport?

A

Stabilise the muscles in the shoulder to help prevent dislocation and allows the shoulder to rotate the humerus around it’s own axis.
A throwing action such as a javelin throw

45
Q

What does the pectorals do and what is an example of it in sport?

A

Adduction of the shoulder (moving the arm towards the body) and shoulder horizontal flexion (moving the arms forward in front of the body)
Upwards phase of a push up

46
Q

What does the intercostals do and what is an example of it in sport?

A

Assist with the breathing process

All sports but especially in endurance events

47
Q

What does the triceps do and what is an example of it in sport?

A

Extend the elbow

Shooting in netball

48
Q

What does the biceps do and what is an example of it in sport?

A

Flex the elbow

Drawing a bow in archery

49
Q

What does the abdominals do and what is an example of it in sport?

A

Flex the trunk across the stomach (sitting upwards)

Performing a sit up

50
Q

What does the latissimus dorsi do and what is an example of it in sport?

A

Shoulder adduction (moving the arm towards the body) and shoulder horizontal flexion (moving the arms forward in front of the body)

51
Q

What does the quadriceps do and what is an example of it in sport?

A

Extend the knee

Kicking a ball

52
Q

What does the hamstrings do and what is an example of it in sport?

A

Flex the knee

Performing a hamstring curl on a weights machine

53
Q

What does the gastrocnemius do and what is an example of it in sport?

A

Plantar flexion of the ankle (pointing the toes)

Standing on tiptoe to mark someone in netball

54
Q

What does the tibialis anterior do and what is an example of it in sport?

A

Dorsiflexion of the ankle (bringing the toes towards the shin)
Foot making contact with a football

55
Q

What is isotonic contraction?

A

When a muscle contracts and changes length

56
Q

What is isotonic concentric contraction?

A

This is when the muscle shortens and goes closer together making it become fatter

57
Q

What is isotonic eccentric contraction?

A

This is when the muscle lengthens whilst under tension. The muscles move away from each other

58
Q

What is isometric contraction?

A

This is when the muscle produces the same tension whilst staying the same length. This is when the body stays in the same position.

59
Q

How do muscles transfer force to the bones?

A

The tendons pull on the body parts. This is called muscle contraction.

60
Q

How does the muscles go back after muscle contraction?

A

Their antagonistic muscle pair contracts whilst the other muscle relaxes or lengthens

61
Q

What is the muscle contracting called in antagonistic muscle pairs?

A

Agonist

62
Q

What is the muscle relaxing or lengthening called in antagonistic muscle pairs?

A

Antagonist

63
Q

What is the antagonistic muscle pair for the biceps?

A

Triceps

64
Q

What is the antagonistic muscle pair for the hamstrings?

A

Quadriceps

65
Q

What is the antagonistic muscle pair for the hip flexors?

A

Gluteals

66
Q

What is the antagonistic muscle pair for the gastrocnemius?

A

Tibialis anterior

67
Q

What is the antagonistic muscle pair for the pectorals?

A

Latissimus dorsi

68
Q

Describe how the antagonistic muscle pairs are working at the elbow during the downwards and upwards phase of a press up

A

During the downwards phase, the triceps are the agonist and they contract eccentrically to control the flexion of the elbow so the body is lowered under control down towards the floor. The biceps are the antagonist .During the upwards phase, the biceps are the agonist and contract concentrically to extend the elbow and the triceps are the antagonist.
