25
Which movements occur in a saggital plane about a transverse axis
- Flexion, extension - plantar flexion, dorsi flexion - hyper-extension
26
What movements occur in a frontal plane about a saggital axis
Abduction and adduction
27
What movements occur in a transverse plane about a longitudinal axis
Horizontal abduction and horizontal adduction
28
What is flexion
Decreasing the angle between the bones of a joint
29
What is extension
Increasing the angle between bones of a joint
30
What is plantar flexion
Pointing the toes/pushing up on to your toes
31
What is dorsi flexion
Pulling the toes up to the shin
32
What is hyper extension
Increasing the angle beyond 180° between the bones of a joint
33
What is abduction
A movement away from the midline of the body
34
What is adduction
A movement towards the midline of the body
35
What is horizontal abduction
Movement of the body part backwards across the body to abduction
36
What is horizontal adduction
The movement of the body part forwards across the body at 90° to adduction
37
Define agonist
The muscle that is responsible for the movement that is occurring, the muscle which contracts whilst the movement happens
38
Define antagonist
The muscle that works in opposition to the agonist, the muscle that is relaxing while a movement happens
39
Can there be more than one agonist
Yes there can although this does depend on the type of movement that is being performed
40
What is the iliopsoas also known as
The hip flexors
41
What is the agonist and antagonist for this joint action : Elbow flexion
Agonist: Biceps Antagonist: Triceps
42
What is the agonist and antagonist for this joint action : Elbow extension
Agonist: Triceps Antagonist: Biceps
43
What is the agonist and antagonist for this joint action : Ankle plantar-flexion
Agonist: Gastrocnemius Antagonist: Tibialis anterior
44
What is the agonist and antagonist for this joint action : Ankle dorsi flexion

45
What is the agonist and antagonist for this joint action : Knee flexion
Agonist: hamstring Antagonist: quadriceps
46
What is the agonist and antagonist for this joint action : Knee extension
Agonist: quadriceps Antagonist: hamstrings
47
What is the agonist and antagonist for this joint action : Hip flexion
Agonist: hip flexors Antagonist: gluteals
48
What is the agonist and antagonist for this joint action : hip extension/hyper extension

56
What is the agonist and antagonist for this joint action : shoulder horizontal adduction

58
What is the agonist and antagonist for this joint action : shoulder abduction
Agonist: middle deltoid Antagonist: posterior deltoid/latissimus dorsi
59
What is a concentric contraction
When a muscle shortens under tension E.g. elbow flexion, biceps brachii is the agonist
60
What is eccentric contraction
When a muscle lengthens under tension or performs negative work and acts like a brake E.g. triceps lengthen under tension, acts like a brake in the middle of a push up
61
What is a isometric contraction
When a muscle is under tension but there is no visible movement E.g. muscles are contracting in plank but no visible movement
62
What is a isotonic contraction
When a muscles length changes to create a movement Two types: concentric and eccentric
