What does Superior mean? | Towards the head |
What does Inferior mean? | Toward the feet |
What does Medial mean? | Toward or at the midline of the body |
What does Lateral mean? | Away from the midline of the body |
What does Proximal mean? | Located nearer to a point of reference |
What does Distal mean? | Located further from a point of reference |
What does Flexion mean? | Away movement that decreases the angle of the joint |
What does Extension mean? | Any movement that increase the angle of the joint |
What does Abduction mean? | Movement of a limb away from the body |
What does Adduction mean? | Movement of a limb towards the body |
What does Rotation mean? | Movement of a bone around its longitude axis without lateral or medial displacement, such as shaking the head |
What does Circumduction mean? | Combination of flexion, abduction, extension and adduction performed one after the other |
What does Supination mean? | Movement so the radius and ulna at the elbow so that the palm is up |

What is Kinematics? | Motion of a body |
Three types of motion? | Linear motion, Angular motion, General motion |
Define linear motion? | Motion of a body in a straight line |
Define angular motion? | Motions of all parts of the object move around a fixed point. |
Define general motion? | Combination of linear and angular. e.g. Swimming. |
Which type of motion can be internal and external? | Angular motion, eg internal: Shoulder Joint, External: Eneven Bars |
What is projectile motion? | Object which moves through the air |
What are the factors affecting projectile motion? (6) | Velocity at release, Angle of release, Height of release, Shape, Air Resistance and Spin |
Give an example of an object which would have a angle of release over 45 degrees and one below 45 degrees? | U: Bowl in cricket H: Netball shot |
Briefly explain velocity at release? | The harder a ball is hit or thrown the higher and further it'll travel |
Briefly explain angle of release? | Angle of release depends of the shape and aerodynamic properties of the projectile |
Briefly explain height of release? | Higher the point of release relative to the ground the further the projectile will follow |
Briefly explain what the shape has to do with projectile motion? | Streamlined shapes travel more effectively in the air due to less drag force |
What is Air Resistance? | When a projectile pushes through the air it creates a drag force behind it |
What is Kinetics? | Forces associated with motion |
Define mass and what it is measured in? | Amount of matter that makes up an object, measured in KG |
Define force? and what is it measured in? | Is the push or pull on a body that can possibly cause change, me |
Two types of forces? | From within the body by muscular contractions, With an aid of equipment |
Newtons first law of motion? | A body continues in it's state of rest or state of motion unless acted upon by a force |
Force can achieve what? | Acceleration, Deceleration, Stop, Start, Change shape, Change Direction |
Newtons second law of motion? | Force = mass x acceleration |
Newtons third law of motion? | For every action there will be an equal and opposite reaction |
What acts as leavers and what acts as axis? | Bones act as leavers while joints act as axis |
Define Stability? | The body's ability to remain in a state of balance, stability can be static or dynamic. |
Why do we analyse performance? (3) | Ensure the correct techniques are being used
Identify Errors
Justify the suggested changes in technique that are recommended |
How many steps are there in biomechanical analysis? | 6 |
